CMS Energy Corporation
Consumers Energy Company
Management’s Discussion and Analysis of Financial Condition and Results of Operations
This MD&A is a combined report of CMS Energy and Consumers.
Executive Overview
CMS Energy is an energy company operating primarily in Michigan. It is the parent holding company of several subsidiaries, including Consumers, an electric and gas utility, and NorthStar Clean Energy, primarily a domestic independent power producer and marketer. Consumers’ electric utility operations include the generation, purchase, distribution, and sale of electricity, and Consumers’ gas utility operations include the purchase, transmission, storage, distribution, and sale of natural gas. Consumers’ customer base consists of a mix of primarily residential, commercial, and diversified industrial customers. NorthStar Clean Energy, through its subsidiaries and equity investments, is engaged in domestic independent power production, including the development and operation of renewable generation, and the marketing of independent power production.
CMS Energy and Consumers manage their businesses by the nature of services each provides. CMS Energy operates principally in three business segments: electric utility; gas utility; and NorthStar Clean Energy, its non‑utility operations and investments. Consumers operates principally in two business segments: electric utility and gas utility. CMS Energy’s and Consumers’ businesses are affected primarily by:
regulation and regulatory matters
state and federal legislation
economic conditions
weather
energy commodity prices
interest rates
their securities’ credit ratings
The Triple Bottom Line
CMS Energy’s and Consumers’ purpose is to achieve world class performance while delivering hometown service. In support of this purpose, CMS Energy and Consumers employ the “CE Way,” a lean operating model designed to improve safety, quality, cost, delivery, and employee morale.
CMS Energy and Consumers measure their progress toward the purpose by considering their impact on the “triple bottom line” of people, planet, and profit, which is underpinned by performance; this consideration takes into account not only the economic value that CMS Energy and Consumers create for customers and investors, but also their responsibility to social and environmental goals. The triple bottom line balances the interests of employees, customers, suppliers, regulators, creditors, Michigan’s residents,
14

the investment community, and other stakeholders, and it reflects the broader societal impacts of CMS Energy’s and Consumers’ activities.
cms.jpg
CMS Energy’s Environmental, Social, Governance and Sustainability Report, which is available to the public, describes CMS Energy’s and Consumers’ progress toward world class performance measured in the areas of people, planet, and profit.
People: The people element of the triple bottom line represents CMS Energy’s and Consumers’ commitment to their employees, their customers, the residents of local communities in which they do business, and other stakeholders.
The safety of employees, customers, and the general public is a priority of CMS Energy and Consumers. Accordingly, CMS Energy and Consumers have worked to integrate a set of safety principles into their business operations and culture. These principles include complying with applicable safety, health, and security regulations and implementing programs and processes aimed at continually improving safety and security conditions. Over the last ten years, Consumers’ Occupational Safety and Health Administration recordable incident rate has decreased by 34 percent.
CMS Energy and Consumers also place a high priority on customer value and on providing a hometown customer experience. Consumers’ customer-driven investment program is aimed at improving safety and increasing electric and gas reliability, which has resulted in measurable improvements in customer satisfaction.
Central to Consumers’ commitment to its customers are the initiatives it has undertaken to keep electricity and natural gas affordable, including:
replacement of coal-fueled generation and PPAs with a cost-efficient mix of renewable energy, less-costly dispatchable generation sources, and energy waste reduction and demand response programs
targeted infrastructure investment to reduce maintenance costs and improve reliability and safety
supply chain optimization
economic development to increase sales and reduce overall rates
information and control system efficiencies
employee and retiree health care cost sharing
workforce productivity enhancements
While CMS Energy and Consumers have experienced some supply chain disruptions and inflationary pressures, they have taken steps to mitigate the impact on their ability to provide safe and reliable service to customers.
Planet: The planet element of the triple bottom line represents CMS Energy’s and Consumers’ commitment to protect the environment. This commitment extends beyond compliance with various state
15

and federal environmental, health, and safety laws and regulations. Management considers climate change and other environmental risks in strategy development, business planning, and enterprise risk management processes.
CMS Energy and Consumers continue to focus on opportunities to protect the environment and to reduce their carbon footprint. As a result of actions already taken through 2022, CMS Energy and Consumers have:
decreased their combined percentage of electric supply (self-generated and purchased) from coal by 17 percentage points since 2015
reduced carbon dioxide emissions by over 30 percent since 2005
reduced the amount of water used to generate electricity by over 35 percent since 2012
reduced landfill waste disposal by over 1.7 million tons since 1992
reduced methane emissions by more than 20 percent since 2012
Since 2005, Consumers has reduced its sulfur dioxide and particulate matter emissions by over 90 percent and its NOx emissions by over 80 percent. Consumers began tracking mercury emissions in 2007; since that time, it has reduced such emissions by nearly 90 percent.
The 2016 Energy Law:
raised the renewable portfolio standard to 15 percent in 2021; Consumers has met the 15percent requirement and expects to continue meeting the requirement going forward with a combination of newly generated RECs and previously generated RECs carried over from prior years
established a goal of 35percent combined renewable energy and energy waste reduction by 2025; Consumers achieved 33percent combined renewable energy and energy waste reduction through 2022
authorized incentives for demand response programs and energy efficiency programs, referring to the combined initiatives as energy waste reduction programs
established an integrated planning process for new electric capacity and energy resources
Consumers’ Clean Energy Plan details its strategy to meet customers’ long-term energy needs. The Clean Energy Plan was most recently revised and approved by the MPSC in June 2022. Under its Clean Energy Plan, Consumers will meet the requirements of the 2016 Energy Law using its clean and lean strategy, which focuses on increasing the generation of renewable energy, helping customers use less energy, and offering demand response programs to reduce demand during critical peak times.
The Clean Energy Plan outlines Consumers’ long-term strategy for delivering clean, reliable, resilient, and affordable energy to its customers, including plans to:
end the use of coal-fueled generation in 2025, 15 years sooner than initially planned
purchase an existing natural gas-fueled generating unit, providing an additional 1,176 MW of nameplate capacity and allowing Consumers to continue to provide controllable sources of electricity to customers
solicit approximately 700 MW of capacity through PPAs from sources able to deliver to Michigan’s Lower Peninsula beginning in 2025
expand its investment in renewable energy, adding nearly 8,000 MW of solar generation by 2040
Under the Clean Energy Plan, Consumers earns a return equal to its weighted-average cost of capital on payments made under new competitively bid PPAs with non-affiliated entities approved by the MPSC.
16

The Clean Energy Plan will allow Consumers to exceed its breakthrough goal of at least 50percent combined renewable energy and energy waste reduction by 2030.
Presented in the following illustration is Consumers’ 2021 capacity portfolio and its future capacity portfolio under its Clean Energy Plan. This illustration includes the effects of purchased capacity and energy waste reduction and uses the nameplate capacity for all energy sources:
7801
1    Does not include RECs.
2    These amounts and fuel sources will vary and are dependent on a one-time competitive solicitation to acquire approximately 700 MW of capacity through PPAs from sources able to deliver to Michigan’s Lower Peninsula beginning in 2025.
In addition to Consumers’ plan to eliminate its use of coal-fueled generation in 2025, CMS Energy and Consumers have set the net‑zero emissions goals discussed below.
Net-zero methane emissions from natural gas delivery system by 2030: Under its Methane Reduction Plan, Consumers plans to reduce methane emissions from its system by about 80 percent by accelerating the replacement of aging pipe, rehabilitating or retiring outdated infrastructure, and adopting new technologies and practices. The remaining emissions will likely be offset by purchasing and/or producing renewable natural gas.
Net-zero carbon emissions from electric business by 2040: This goal includes not only emissions from owned generation, but also emissions from the generation of power purchased through long-term PPAs and from the MISO energy market. Consumers expects to meet 90 percent of its customers’ needs with clean energy sources by 2040 through execution of its Clean Energy Plan. New technologies and carbon offset measures including, but not limited to, carbon sequestration, methane emission capture, forest preservation, and reforestation may be used to close the gap to achieving net-zero carbon emissions.
17

Net-zero greenhouse gas emissions target for the entire business by 2050: This goal, announced in March 2022, incorporates greenhouse gas emissions from Consumers’ natural gas delivery system, including suppliers and customers, and has an interim goal of reducing customer emissions by 20 percent by 2030. Consumers expects to meet this goal through carbon offset measures, renewable natural gas, energy efficiency and demand response programs, and the adoption of cost-effective emerging technologies once proven and commercially available.
Additionally, to advance its environmental stewardship in Michigan and to minimize the impact of future regulations, Consumers set the following targets in 2022:
to enhance, restore, or protect 6,500 acres of land by 2026; in 2022, Consumers enhanced, restored, or protected over 700 acres of land
to reduce water usage by 1.5 billion gallons by 2026; in 2022, Consumers reduced water usage by more than 750 million gallons
to increase the rate of waste diverted from landfills (through waste reduction, recycling, and reuse) to 90 percent from a baseline of 88 percent through 2023; in 2022, Consumers’ rate of waste diverted from landfills was 92 percent
CMS Energy and Consumers are monitoring numerous legislative, policy, and regulatory initiatives, including those to regulate and report greenhouse gases, and related litigation. While CMS Energy and Consumers cannot predict the outcome of these matters, which could affect them materially, they intend to continue to move forward with their clean and lean strategy.
Profit: The profit element of the triple bottom line represents CMS Energy’s and Consumers’ commitment to meeting their financial objectives and providing economic development opportunities and benefits in the communities in which they do business. CMS Energy’s and Consumers’ financial strength allows them to maintain solid investment-grade credit ratings and thereby reduce funding costs for the benefit of customers and investors, to attract and retain talent, and to reinvest in the communities they serve.
For the three months ended March 31, 2023, CMS Energy’s net income available to common stockholders was $202 million, and diluted EPS were $0.69. This compares with net income available to common stockholders of $351 million and diluted EPS of $1.21 for the three months ended March 31, 2022. In 2023, lower gas and electric sales due primarily to unfavorable weather, and higher service restoration costs, were partially offset by gas and electric rate increases. A more detailed discussion of the factors affecting CMS Energy’s and Consumers’ performance can be found in the Results of Operations section that follows this Executive Overview.
Over the next five years, Consumers expects weather-normalized electric and gas deliveries to remain relatively stable compared to 2022. This outlook reflects the effects of energy waste reduction programs offset largely by modest growth in electric and gas demand.
Performance: Impacting the Triple Bottom Line
CMS Energy and Consumers remain committed to achieving world class performance while delivering hometown service and positively impacting the triple bottom line of people, planet, and profit. During 2022, CMS Energy and Consumers:
settled and received approval of Consumers’ Clean Energy Plan, gas rate case, and electric rate case, demonstrating the constructive nature of Michigan’s regulatory environment
partnered with state and federal agencies to secure over $100 million of customer assistance to help keep customer bills affordable
18

CMS Energy and Consumers will continue to utilize the CE Way to enable them to achieve world class performance and positively impact the triple bottom line. Consumers’ investment plan and the regulatory environment in which it operates also drive its ability to impact the triple bottom line.
Investment Plan: Over the next five years, Consumers expects to make significant expenditures on infrastructure upgrades, replacements, and clean generation. While it has a large number of potential investment opportunities that would add customer value, Consumers has prioritized its spending based on the criteria of enhancing public safety, increasing reliability, maintaining affordability for its customers, and advancing its environmental stewardship. Consumers’ investment program is expected to result in annual rate-base growth of over seven percent. This rate-base growth, together with cost-control measures, should allow Consumers to maintain affordable customer prices.
Presented in the following illustration are planned capital expenditures of $15.5 billion that Consumers expects to make from 2023 through 2027:
14200
19

Of this amount, Consumers plans to spend $12.4 billion over the next five years to primarily maintain and upgrade its gas infrastructure and electric distribution systems in order to enhance safety and reliability, improve customer satisfaction, reduce energy waste on those systems, and facilitate its clean energy transformation. The gas infrastructure projects comprise $6.3 billion to sustain deliverability, enhance pipeline integrity and safety, and reduce methane emissions. Electric distribution and other projects comprise $6.1 billion to strengthen circuits and substations, replace poles, and interconnect clean energy resources. Consumers also expects to spend $3.1 billion on clean generation, which includes investments in wind, solar, and hydroelectric generation resources.
Regulation: Regulatory matters are a key aspect of Consumers’ business, particularly rate cases and regulatory proceedings before the MPSC, which permit recovery of new investments while helping to ensure that customer rates are fair and affordable. Important regulatory events and developments not already discussed are summarized below.
2022 Gas Rate Case: In December 2022, Consumers filed an application with the MPSC seeking an annual rate increase of $212 million, based on a 10.25percent authorized return on equity for the projected twelve-month period ending September 30, 2024. The filing requests authority to recover new infrastructure investment and related costs that are expected to allow Consumers to improve system safety and reliability and reduce fugitive methane emissions.
2022 Electric Rate Case: In January 2023, the MPSC approved a settlement agreement authorizing an annual rate increase of $155 million, based on a 9.9-percent authorized return on equity. The MPSC also approved a surcharge for the recovery of $6 million of depreciation, property tax, and interest expense related to distribution investments made in 2021 that exceeded what was authorized in rates in accordance with the December 2020 electric rate order. The new rates became effective January 20, 2023.
Looking Forward
CMS Energy and Consumers will continue to consider the impact on the triple bottom line of people, planet, and profit in their daily operations as well as in their long-term strategic decisions. Consumers will continue to seek fair and timely regulatory treatment that will support its customer-driven investment plan, while pursuing cost-control measures that will allow it to maintain sustainable customer base rates. The CE Way is an important means of realizing CMS Energy’s and Consumers’ purpose of achieving world class performance while delivering hometown service.

Capital Resources and Liquidity
CMS Energy and Consumers expect to have sufficient liquidity to fund their present and future commitments. CMS Energy uses dividends and tax-sharing payments from its subsidiaries and external financing and capital transactions to invest in its utility and nonutility businesses, retire debt, pay dividends, and fund its other obligations. The ability of CMS Energy’s subsidiaries, including Consumers, to pay dividends to CMS Energy depends upon each subsidiary’s revenues, earnings, cash needs, and other factors. In addition, Consumers’ ability to pay dividends is restricted by certain terms included in its articles of incorporation and potentially by FERC requirements and provisions under the Federal Power Act of 1920 and the Natural Gas Act of 1938. For additional details on Consumers’ dividend restrictions, see Notes to the Unaudited Consolidated Financial Statements—Note 3, Financings and Capitalization—Dividend Restrictions. During the three months ended March 31, 2023, Consumers paid $287 million in dividends on its common stock to CMS Energy.
Consumers uses cash flows generated from operations and external financing transactions, as well as stockholder contributions from CMS Energy, to fund capital expenditures, retire debt, pay dividends, and fund its other obligations. Consumers also uses these sources of funding to contribute to its employee benefit plans.
Financing and Capital Resources: CMS Energy and Consumers rely on the capital markets to fund their robust capital plan. Barring any sustained market dislocations or disruptions, CMS Energy and Consumers expect to continue to have ready access to the financial and capital markets and will continue to explore possibilities to take advantage of market opportunities as they arise with respect to future funding needs. If access to these markets were to diminish or otherwise become restricted, CMS Energy and Consumers would implement contingency plans to address debt maturities, which could include reduced capital spending.
In January 2023, Consumers entered into a bond purchase agreement to issue an aggregate principal amount of $400 million of first mortgage bonds through a private placement offering. The bonds, which were priced in November 2022, carry a weighted average interest rate of 5.251 percent and mature at varying dates between 2026 and 2037. The bonds are expected to be issued in May 2023. The proceeds of the bonds will be used to finance a portion of the purchase price of the New Covert Generating Facility and for general corporate purposes. For more information on the purchase of the New Covert Generating Facility, see Consumers Electric Utility Outlook and Uncertainties—Clean Energy Plan.
CMS Energy has entered into forward sales transactions that it may either settle physically by issuing shares of its common stock at the then-applicable forward sale price specified by the agreement or settle net by delivering or receiving cash or shares. CMS Energy may settle the contracts at any time through their maturity dates, and presently intends to physically settle the contracts by delivering shares of its common stock. As of March 31, 2023, these contracts have an aggregate sales price of $440 million, maturing through February 2024. For more information on these forward sale contracts, see Notes to the Unaudited Consolidated Financial Statements—Note 3, Financings and Capitalization—Issuance of Common Stock.
At March 31, 2023, CMS Energy had $529 million of its revolving credit facility available and Consumers had $1.3 billion available under its revolving credit facilities. CMS Energy and Consumers use these credit facilities for general working capital purposes and to issue letters of credit. An additional source of liquidity is Consumers’ commercial paper program, which allows Consumers to issue, in one or more placements, up to $500 million in aggregate principal amount of commercial paper notes with maturities of up to 365 days at market interest rates. These issuances are supported by Consumers’ revolving credit facilities. While the amount of outstanding commercial paper does not reduce the available capacity of the revolving credit facilities, Consumers does not intend to issue commercial paper
27

in an amount exceeding the available capacity of the facilities. At March 31, 2023, there were no commercial paper notes outstanding under this program. For additional details on CMS Energy’s and Consumers’ secured revolving credit facilities and commercial paper program, see Notes to the Unaudited Consolidated Financial Statements—Note 3, Financings and Capitalization.
Certain of CMS Energy’s and Consumers’ credit agreements contain covenants that require CMS Energy and Consumers to maintain certain financial ratios, as defined therein. At March 31, 2023, no default had occurred with respect to any financial covenants contained in CMS Energy’s and Consumers’ credit agreements. CMS Energy and Consumers were each in compliance with these covenants as of March 31, 2023, as presented in the following table:

Outlook
Several business trends and uncertainties may affect CMS Energy’s and Consumers’ financial condition and results of operations. These trends and uncertainties could have a material impact on CMS Energy’s and Consumers’ consolidated income, cash flows, or financial position. For additional details regarding these and other uncertainties, see Forward-Looking Statements and Information; Notes to the Unaudited Consolidated Financial Statements—Note 1, Regulatory Matters and Note 2, Contingencies and Commitments; and Part II—Item 1A. Risk Factors.
Consumers Electric Utility Outlook and Uncertainties
Clean Energy Plan: Consumers’ Clean Energy Plan details its strategy to meet customers’ long-term energy needs and provides the foundation for its goal to achieve net-zero carbon emissions from its electric business by 2040. Under this net-zero goal, Consumers plans to eliminate the impact of carbon emissions created by the electricity it generates or purchases for customers. Additionally, through its Clean Energy Plan, Consumers continues to make progress on expanding its customer programs, namely its demand response, energy efficiency, and conservation voltage reduction programs, as well as increasing its renewable energy and pumped storage generation.
The Clean Energy Plan was most recently revised and approved by the MPSC in June 2022. Under this plan, Consumers will eliminate the use of coal-fueled generation in 2025 and expects to meet 90 percent of its customers’ needs with clean energy sources by 2040. Specifically, the Clean Energy Plan provides for:
the retirement of the D.E. Karn coal-fueled generating units, totaling 515 MW of nameplate capacity, in May 2023
the retirement of the J.H. Campbell coal-fueled generating units, totaling 1,407 MW of nameplate capacity, in 2025
28

the retirement of the D.E. Karn oil and gas-fueled generating units, totaling 1,219 MW of nameplate capacity, in 2031, the units’ original retirement date
The MPSC has authorized Consumers to issue securitization bonds to finance the recovery of and return on the D.E. Karn coal-fueled generating units. Additionally, the MPSC has authorized regulatory asset treatment for Consumers to recover the remaining book value of the J.H. Campbell coal-fueled generating units, as well as a 9.0‑percent return on equity, commencing in 2025.
Under the Clean Energy Plan, Consumers will:
purchase the New Covert Generating Facility, a natural gas-fueled generating unit with 1,176 MW of nameplate capacity in Van Buren County, Michigan, for $815 million, subject to certain adjustments, in 2023; the purchase was approved by FERC in November 2022
conduct a one-time competitive solicitation to acquire approximately 700 MW of capacity through PPAs from sources able to deliver to Michigan’s Lower Peninsula beginning in 2025; of this amount, 500 MW would be from dispatchable sources
These actions are expected to help Consumers continue to provide controllable sources of electricity to customers while expanding its investment in renewable energy. The Clean Energy Plan forecasts renewable energy capacity levels of 30 percent in 2025, 43 percent in 2030, and 61 percent in 2040, including the addition of nearly 8,000 MW of solar generation. Additionally, Consumers plans to deploy battery storage beginning in 2024, with 75 MW of energy storage by 2027 and an additional 475 MW by 2040.
Under its Clean Energy Plan, Consumers bids new capacity competitively and will own and operate approximately 50 percent of new capacity, with the remainder being built and owned by third parties. Additionally, Consumers earns a return equal to its weighted-average cost of capital on payments made under new competitively bid PPAs with non-affiliated entities approved by the MPSC.
29

As a result of requests for proposals, Consumers has entered into PPAs to purchase renewable capacity, energy, and RECs from solar generating facilities and build transfer agreements to purchase solar generating facilities. Presented in the following illustration is the aggregate renewable capacity that Consumers expects to add to its portfolio as a result of these agreements:
3902
In support of its Clean Energy Plan, Consumers issued a request for proposals in September 2022 to acquire approximately 700 MW of capacity through PPAs from sources able to deliver to Michigan’s Lower Peninsula beginning in 2025. Specifically, Consumers solicited offers to acquire 500 MW of capacity from dispatchable sources and 200 MW of capacity from intermittent resources and dispatchable, non-intermittent clean capacity resources (including battery storage resources).
In March 2022, the U.S. Department of Commerce announced it is opening inquiries into whether manufacturers of solar modules that are produced in certain countries using supplies obtained from China are circumventing antidumping and countervailing duties which apply to Chinese modules. The U.S. Department of Commerce has made an initial determination that four manufacturers have circumvented tariffs. The remainder of this inquiry process is continuing, with a final ruling expected in May 2023. In June 2022, the Biden Administration paused for two years the imposition of duties that might result from the U.S. Department of Commerce’s pending inquiries. In addition, the Uyghur Forced Labor Prevention Act, which was enacted in 2021 and became effective in June 2022, along with an earlier withhold release order that U.S. Customs and Border Protection issued in 2021, restrict the importation of goods sourced from the Xinjiang region of China. Solar modules whose raw materials come from the Xinjiang region are a key focus of these import laws. Consumers continues to closely monitor these matters and their potential impacts on availability of solar modules and timing associated with pending and planned solar projects.
Renewable Energy Plan: Michigan has established a 15-percent renewable portfolio standard. Under this standard, Consumers is required to submit RECs, which represent proof that the associated electricity was generated from a renewable energy resource, in an amount equal to at least 15 percent of Consumers’ electric sales volume each year. Under its renewable energy plan, Consumers has met the 15percent
30

requirement and expects to continue meeting the requirement going forward with a combination of newly generated RECs and previously generated RECs carried over from prior years.
Under Consumers’ renewable energy plan, the MPSC has approved the acquisition of up to 525 MW of new wind generation projects and authorized Consumers to earn a 10.7percent return on equity on any projects approved by the MPSC. Specifically, the MPSC has approved the following:
purchase and construction of a 150MW wind generation project in Gratiot County, Michigan; the project became operational and Consumers took full ownership in 2020
purchase of a 166MW wind generation project in Hillsdale, Michigan; the project became operational and Consumers took full ownership in 2021
purchase of a wind generation project under development, with capacity of up to 201 MW, in Gratiot County, Michigan; Consumers expects to take full ownership and begin commercial operation of the project in the fourth quarter of 2023
The MPSC also approved the execution of a 20-year PPA under which Consumers will purchase 100 MW of renewable capacity, energy, and RECs from a 149MW solar generating facility to be constructed in Calhoun County, Michigan; the facility is targeted to be operational in 2024.
Voluntary Large Customer Renewable Energy Program: Consumers provides service under a program that provides large full-service electric customers with the opportunity to advance the development of renewable energy beyond the requirements of the 2016 Energy Law. In 2021, the MPSC approved Consumers’ request to amend its renewable energy plan to remove the annual subscription limit associated with this program. The MPSC also approved up to 1,000 MW of new wind and solar generation projects between 2024 and 2027 to meet customer demand for the program. Consumers will competitively solicit for additional renewable energy assets based on customer applications and will construct the assets based on customer subscriptions to the program. In March 2023, Consumers entered into a build transfer agreement for a 309‑MW solar generating facility to be constructed in Calhoun County, Michigan; the facility is targeted to be operational in 2025. The build transfer agreement is subject to MPSC approval.
Electric Customer Deliveries and Revenue: Consumers’ electric customer deliveries are seasonal and largely dependent on Michigan’s economy. The consumption of electric energy typically increases in the summer months, due primarily to the use of air conditioners and other cooling equipment. In addition, Consumers’ electric rates, which follow a seasonal rate design, are higher in the summer months than in the remaining months of the year. Each year in June, electric residential customers transition to a summer peak time-of-use rate that allows them to take advantage of lower-cost energy during off-peak times during the summer months. Thus, customers can reduce their electric bills by shifting their consumption from on‑peak to off‑peak times.
Over the next five years, Consumers expects weather-normalized electric deliveries to remain relatively stable compared to 2022. This outlook reflects the effects of energy waste reduction programs offset largely by modest growth in electric demand. Actual delivery levels will depend on:
energy conservation measures and results of energy waste reduction programs
weather fluctuations
Michigan’s economic conditions, including utilization, expansion, or contraction of manufacturing facilities, population trends, electric vehicle adoption, and housing activity
Electric ROA: Michigan law allows electric customers in Consumers’ service territory to buy electric generation service from alternative electric suppliers in an aggregate amount capped at ten percent of Consumers’ sales, with certain exceptions. At March 31, 2023, electric deliveries under the ROA program
31

were at the ten‑percent limit. Of Consumers’ 1.9 million electric customers, fewer than 300, or 0.02 percent, purchased electric generation service under the ROA program.
The 2016 Energy Law established a path to ensure that forward capacity is secured for all electric customers in Michigan, including customers served by alternative electric suppliers under ROA. The law also authorized the MPSC to ensure that alternative electric suppliers have procured enough capacity to cover their anticipated capacity requirements for the four-year forward period. In 2017, the MPSC issued an order establishing a state reliability mechanism for Consumers. Under this mechanism, if an alternative electric supplier does not demonstrate that it has procured its capacity requirements for the four-year forward period, its customers will pay a set charge to the utility for capacity that is not provided by the alternative electric supplier.
During 2017, the MPSC issued orders finding that it has statutory authority to determine and implement a local clearing requirement, which requires all electric suppliers to demonstrate that a portion of the capacity used to serve customers is located in the MISO footprint in Michigan’s Lower Peninsula. In 2020, the Michigan Supreme Court affirmed the MPSC’s statutory authority to implement a local clearing requirement on individual electric providers.
In 2020, ABATE and another intervenor filed a complaint against the MPSC in the U.S. District Court for the Eastern District of Michigan challenging the constitutionality of a local clearing requirement. The complaint requests the federal court to issue a permanent injunction prohibiting the MPSC from implementing a local clearing requirement on individual electric providers. In February 2023, the U.S. District Court for the Eastern District of Michigan dismissed the complaint. In March 2023, ABATE and the other intervenor filed a claim of appeal of the Eastern District Court’s decision with the U.S. Court of Appeals for the Sixth Circuit. In April 2023, Consumers and the MPSC filed appearances and also filed cross-appeals.
Electric Rate Matters: Rate matters are critical to Consumers’ electric utility business. For additional details on rate matters, see Notes to the Unaudited Consolidated Financial Statements—Note 1, Regulatory Matters and Note 2, Contingencies and Commitments.
MPSC Distribution System Audit: In October 2022, the MPSC ordered the state’s two largest electric utilities, including Consumers, to report on their compliance with regulations and past MPSC orders governing the utilities’ response to outages and downed lines. Also, the MPSC Staff was directed to engage a third-party auditor to review all equipment and operations of the two utilities’ distribution systems.
Consumers has responded to the MPSC’s order and awaits further action by the MPSC. Consumers is committed to working with other state utilities, the third-party auditor, and the MPSC to continue improving electric reliability and safety in Michigan. In March 2023, the MPSC Staff issued a request for proposal to engage a third-party auditor and is expected to execute a contract by September 2023.
Retention Incentive Program: Under its Clean Energy Plan, Consumers will retire the D.E. Karn coal-fueled electric generating units in May 2023 and the J.H. Campbell coal-fueled generating units in 2025. Consumers has announced retention incentive programs to ensure necessary staffing at both locations through the anticipated retirements. The aggregate cost of the D.E. Karn program through 2022 was $31 million, and Consumers expects to recognize an additional $2 million of retention benefit costs in the first half of 2023. The aggregate cost of the J.H. Campbell program through 2025 is estimated to be $50 million; Consumers expects to recognize $16 million of retention benefit costs in 2023. The MPSC has approved deferred accounting treatment for these costs; this expense will be deferred as a regulatory asset. For additional details on these programs, see Notes to the Unaudited Consolidated Financial Statements—Note 12, Exit Activities.
32

Electric Environmental Outlook: Consumers’ electric operations are subject to various federal, state, and local environmental laws and regulations. Consumers estimates that it will incur capital expenditures of $210 million from 2023 through 2027 to continue to comply with RCRA, the Clean Air Act, and numerous other environmental regulations. Consumers expects to recover these costs in customer rates, but cannot guarantee this result. Multiple environmental laws and regulations are subject to litigation. Consumers’ primary environmental compliance focus includes, but is not limited to, the following matters.
Air Quality: Multiple air quality regulations apply, or may apply, to Consumers’ electric utility.
In 2012, the EPA published emission standards for electric generating units, known as MATS, based on Section 112 of the Clean Air Act. Consumers has complied, and continues to comply, with the MATS regulation, and does not expect MATS to materially impact its environmental strategy.
CSAPR requires Michigan and many other states to improve air quality by reducing power plant emissions that, according to EPA modeling, contribute to ground-level ozone in other downwind states. Since its 2015 effective date, CSAPR has been revised several times. In March 2023, the EPA finalized a revision to CSAPR affecting Michigan. This regulation establishes allowance budgets for electric generating units in 22 states, including Michigan, between 2023 and 2029 and changes the mechanism for allocating such allowances on a year-over-year basis beginning in 2026. Consumers is evaluating potential cost impacts from this regulation on its electric generating units.
In 2015, the EPA lowered the NAAQS for ozone and made it more difficult to construct or modify power plants and other emission sources in areas of the country that do not meet the ozone standard. In 2018, the EPA designated certain areas of Michigan as not meeting the ozone standard. None of Consumers’ fossil-fuel-fired generating units are located in these areas. Additionally, in January 2023, the EPA proposed lowering the NAAQS for particulate matter. Consumers will continue to monitor NAAQS rulemakings and evaluate potential impacts to its generating assets.
Consumers’ strategy to comply with air quality statutes and regulations involved the installation and operation of emission control equipment at some facilities and the suspension of operations at others; however, Consumers continues to evaluate these rules in conjunction with other EPA and EGLE rulemakings, litigation, executive orders, treaties, and congressional actions. This evaluation could result in:
a change in Consumers’ fuel mix
changes in the types of generating units Consumers may purchase or build in the future
changes in how certain units are operated
the retirement, mothballing, or repowering with an alternative fuel of some of Consumers’ generating units
changes in Consumers’ environmental compliance costs
the purchase or sale of allowances
Greenhouse Gases: There have been numerous legislative and regulatory initiatives at the state, regional, national, and international levels that involve the potential regulation and reporting of greenhouse gases. Consumers continues to monitor and comment on these initiatives, as appropriate.
In June 2022, the EPA announced its plan to propose a new rule to address greenhouse gas emissions from existing fossil-fuel-fired electric generating units. Under its Clean Energy Plan, Consumers will eliminate the use of coal-fueled generation in 2025. Therefore, it is unlikely that the proposed rule will materially impact Consumers over the remaining operating lives of these coal-fueled facilities. However,
33

Consumers cannot predict the form and extent of such potential regulation on its natural gas-fueled generation until this rule is released.
Under the Paris Agreement, an international agreement addressing greenhouse gas emissions, the U.S. has committed to reduce greenhouse gas emissions by 50 to 52 percent from 2005 levels by 2030. Under its Clean Energy Plan, Consumers plans to reduce carbon emissions from its electric business by 60 percent from 2005 levels in 2025. At this time, Consumers does not expect any adverse changes to its environmental strategy as a result of this event, as its plans exceed the nationally committed reduction. The commitment made by the U.S. is not binding without new Congressional legislation.
In 2020, Michigan’s Governor signed an executive order creating the Michigan Healthy Climate Plan, which outlines goals for Michigan to achieve economy-wide net-zero greenhouse gas emissions and to be carbon neutral by 2050. The executive order aims for a 28percent reduction below 2005 levels of greenhouse gas emissions by 2025. These goals are aspirational in nature and any changes in law or regulation to achieve these goals would need to be approved by the Michigan Legislature or the relevant regulatory agency. Additionally, Consumers has already surpassed the 28percent reduction milestone for its owned electric generation and previously announced a goal of achieving net-zero carbon emissions from its electric business by 2040. Consumers does not expect any adverse changes to its environmental strategy as a result of this event.
Increased frequency or intensity of severe or extreme weather events, including those due to climate change, could materially impact Consumers’ facilities, energy sales, and results of operations. Consumers is unable to predict these events or their financial impact; however, Consumers evaluates the potential physical impacts of climate change on its operations, including increased frequency or intensity of storm activity; increased precipitation; increased temperature; and changes in lake and river levels. Consumers released a report addressing the physical risks of climate change on its infrastructure in 2022. Consumers is taking steps to mitigate these risks as appropriate.
While Consumers cannot predict the outcome of changes in U.S. policy or of other legislative, executive, or regulatory initiatives involving the potential regulation or reporting of greenhouse gases, it intends to move forward with its Clean Energy Plan, its present net-zero goals, and its emphasis on reliable and resilient supply. Litigation, international treaties, executive orders, federal laws and regulations (including regulations by the EPA), and state laws and regulations, if enacted or ratified, could ultimately impact Consumers. Consumers may be required to:
replace equipment
install additional emission control equipment
purchase emission allowances or credits (including potential greenhouse gas offset credits)
curtail operations
arrange for alternative sources of supply
purchase facilities that generate fewer emissions
mothball or retire facilities that generate certain emissions
pursue energy efficiency or demand response measures more swiftly
take other steps to manage or lower the emission of greenhouse gases
Although associated capital or operating costs relating to greenhouse gas regulation or legislation could be material and cost recovery cannot be assured, Consumers expects to recover these costs in rates consistent with the recovery of other reasonable costs of complying with environmental laws and regulations.
CCRs: In 2015, the EPA published a rule regulating CCRs under RCRA. This rule adopts minimum standards for beneficially using and disposing of non‑hazardous CCRs and establishes technical
34

requirements for CCR landfills and surface impoundments. The rule also sets out conditions under which some CCR units would be forced to cease receiving CCR wastewater and initiate closure. Due to continued litigation, many aspects of the rule have been remanded to the EPA, resulting in more proposed and final rules.
Separately, Congress passed legislation in 2016 allowing participating states to develop permitting programs for CCRs under RCRA Subtitle D. In 2020, EGLE submitted a regulatory package for Michigan’s permit program to the EPA for its review, which is still pending.
Consumers, with agreement from EGLE, completed the work necessary to initiate closure by excavating CCRs or placing a final cover over each of its relevant CCR units prior to the closure initiation deadline. Consumers has historically been authorized to recover in electric rates costs related to coal ash disposal sites.
Water: Multiple water-related regulations apply, or may apply, to Consumers.
The EPA regulates cooling water intake systems of existing electric generating plants under Section 316(b) of the Clean Water Act. The rules seek to reduce alleged harmful impacts on aquatic organisms, such as fish. In 2018, Consumers submitted to EGLE for approval all required studies and recommended plans to comply with Section 316(b) for its coal-fueled units, but has not yet received final approval.
The EPA also regulates the discharge of wastewater through its effluent limitation guidelines for steam electric generating plants. In 2020, the EPA revised previous guidelines related to the discharge of certain wastewater, but allowed for extension of the compliance deadline from the end of 2023 to the end of 2025, upon approval by EGLE through the NPDES permitting process. Consumers received such an extension to 2025 for its J.H. Campbell generating facility, which it plans to retire in 2025. In March 2023, the EPA released a proposed rule seeking to replace its 2020 rule and corresponding effluent limitation guidelines. Consumers is evaluating the proposed effluent limitation guidelines for its potential impacts on its generating facilities.
In recent years, the EPA and the U.S. Army Corps of Engineers have proposed changes to the scope of federal jurisdiction over bodies of water and to the frequency of dual jurisdiction in states with authority to regulate the same waters; Michigan is one such state. Additionally, a final 2022 rulemaking changed the definition of “Waters of the United States.” Consumers does not expect adverse changes to its environmental strategy as a result of the current interpretations.
Many of Consumers’ facilities maintain NPDES permits, which are vital to the facilities’ operations. Consumers applies for renewal of these permits every five years. Failure of EGLE to renew any NPDES permit, a successful appeal against a permit, a change in the interpretation or scope of NPDES permitting, or onerous terms contained in a permit could have a significant detrimental effect on the operations of a facility.
Protected Wildlife: Multiple regulations apply, or may apply, to Consumers relating to protected species and habitats.
Statutes like the federal Endangered Species Act, the Migratory Bird Treaty Act, and the Bald and Golden Eagle Protection Act may impact operations at Consumers’ facilities. In 2021, the U.S. Fish and Wildlife Service announced its intent to regulate incidental take under the Migratory Bird Treaty Act. Any resulting permitting and monitoring fees and/or restrictions on operations could impact Consumers’ existing and future operations, including wind and solar generation facilities.
35

Additionally, Consumers is monitoring proposed changes to the listing status of several species within its operational area due to an increase in wildlife-related regulatory activity at federal and state levels. A change in species listed under the Endangered Species Act may impact Consumers’ costs to mitigate its impact on protected species and habitats at certain existing facilities as well as siting choices for new facilities.
Other Matters: Other electric environmental matters could have a material impact on Consumers’ outlook. For additional details on other electric environmental matters, see Notes to the Unaudited Consolidated Financial Statements—Note 2, Contingencies and Commitments—Consumers Electric Utility Contingencies—Electric Environmental Matters.
Consumers Gas Utility Outlook and Uncertainties
Gas Deliveries: Consumers’ gas customer deliveries are seasonal. The peak demand for natural gas typically occurs in the winter due to colder temperatures and the resulting use of natural gas as heating fuel.
Over the next five years, Consumers expects weather-normalized gas deliveries to remain stable relative to 2022. This outlook reflects the effects of energy waste reduction programs offset largely by modest growth in gas demand. Actual delivery levels will depend on:
weather fluctuations
use by power producers
availability and development of renewable energy sources
gas price changes
Michigan’s economic conditions, including population trends and housing activity
the price or demand of competing energy sources or fuels
energy efficiency and conservation impacts
Gas Rate Matters: Rate matters are critical to Consumers’ gas utility business. For additional details on rate matters, see Notes to the Unaudited Consolidated Financial Statements—Note 1, Regulatory Matters and Note 2, Contingencies and Commitments.
2022 Gas Rate Case: In December 2022, Consumers filed an application with the MPSC seeking an annual rate increase of $212 million, based on a 10.25percent authorized return on equity for the projected twelve-month period ending September 30, 2024. The filing requests authority to recover new infrastructure investment and related costs that are expected to allow Consumers to improve system safety and reliability and reduce fugitive methane emissions. Presented in the following table are the components of the requested increase in revenue:
Projected Twelve-Month Period Ending September 302024
Components of the requested rate increase
Investment in rate base$80 
Operating and maintenance costs47 
Cost of capital63 
Sales and other revenue22 
Total$212 
The filing also seeks approval of cost deferral mechanisms that will allow Consumers to defer for future recovery or refund pension and OPEB expense and uncollectible accounts expense above the amounts used to set existing rates.
36

Postretirement Benefits Expense Accounting Application: In January 2023, Consumers filed an application with the MPSC, requesting authority to defer the future recovery or refund of pension and OPEB expenses above or below the amounts used to set existing rates, respectively. Consumers requested this accounting treatment to begin in 2023 and to continue until rates are reset in the 2022 gas rate case. In March 2023, the MPSC denied Consumers’ application, instead recommending that this would be more appropriately considered as part of Consumers’ current gas rate case.
Gas Pipeline and Storage Integrity and Safety: The U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration has published various rules that expand federal safety standards for gas transmission pipelines and underground storage facilities. Initial requirements took effect in 2020, with future regulation phases to be released over numerous years. To comply with these rules, Consumers will incur increased capital and operating and maintenance costs to install and remediate pipelines and to expand inspections, maintenance, and monitoring of its existing pipelines and storage facilities.
Although associated capital or operating and maintenance costs relating to these regulations could be material and cost recovery cannot be assured, Consumers expects to recover such costs in rates consistent with the recovery of other reasonable costs of complying with laws and regulations.
Gas Environmental Outlook: Consumers expects to incur response activity costs at a number of sites, including 23 former MGP sites. For additional details, see Notes to the Unaudited Consolidated Financial Statements—Note 2, Contingencies and Commitments—Consumers Gas Utility Contingencies—Gas Environmental Matters.
Consumers’ gas operations are subject to various federal, state, and local environmental laws and regulations. Multiple environmental laws and regulations are subject to litigation. Consumers’ primary environmental compliance focus includes, but is not limited to, the following matters.
Air Quality: Multiple air quality regulations apply, or may apply, to Consumers’ gas utility.
In March 2023, the EPA finalized a revision to CSAPR affecting Michigan. This regulation will reduce interstate air pollution transport issues that EPA modeling suggests contribute to downwind states attaining or maintaining compliance with the NAAQS for ozone. While prior CSAPR regulations focused only on electric generating units, this latest rule includes other emission sources, including engines at natural gas compressor stations. Compliance with new NOx emission limits is required by May 2026, unless the EPA approves an extension. Consumers is currently evaluating the applicability of the regulation to its gas business and expects to incur costs to retrofit or replace equipment at some of its compressor stations.
In 2015, the EPA lowered the NAAQS for ozone and made it more difficult to construct or modify natural gas compressor stations and other emission sources in areas of the country that do not meet the ozone standard. In 2018, the EPA designated certain areas of Michigan as not meeting the ozone standard. Seven counties in southeastern Michigan were not in attainment with the ozone standard by a 2021 regulatory deadline and, in March 2023, had their ozone nonattainment designations increased from marginal to moderate. EGLE has submitted an attainment redesignation request to EPA based on current ozone data for these seven counties, and is waiting on a final decision. The EPA also recently elevated the nonattainment status of three counties in western Michigan from marginal to moderate. Some of Consumers’ compressor stations are located in these ozone nonattainment areas. Consequently, Consumers has initiated plans to retrofit equipment to lower emissions in compliance with these new regulations at two of its compressor stations located in the nonattainment areas. Additionally, in January 2023, the EPA proposed lowering the NAAQS for particulate matter. Consumers will continue to
37

monitor NAAQS rulemakings and evaluate potential impacts to its compressor stations and other applicable natural gas storage and delivery assets.
Greenhouse Gases: There is increasing interest at the federal, state, and local levels in potential regulation of greenhouse gases or their sources. Such regulation, if adopted, may involve requirements to reduce methane emissions from Consumers’ gas utility operations and carbon dioxide emissions from customer use of natural gas. No such measures apply to Consumers at this time.
In 2020, Michigan’s Governor signed an executive order creating the Michigan Healthy Climate Plan, which outlines goals for Michigan to achieve economy-wide net-zero greenhouse gas emissions and to be carbon neutral by 2050. The executive order aims for a 28percent reduction below 2005 levels of greenhouse gas emissions by 2025. For additional details on the executive order, see Consumers Electric Utility Outlook and Uncertainties—Electric Environmental Outlook.
Under the Paris Agreement, an international agreement addressing greenhouse gas emissions, the U.S. has committed to reduce greenhouse gas emissions by 50 to 52 percent from 2005 levels by 2030. The commitment made by the U.S. is not binding without new Congressional legislation. Consumers continues to monitor these initiatives and comment as appropriate. Consumers cannot predict the impact of any potential future legislation or regulation on its gas utility.
Consumers is making voluntary efforts to reduce its gas utility’s methane emissions. Under its Methane Reduction Plan, Consumers has set a goal of net-zero methane emissions from its natural gas delivery system by 2030. Consumers plans to reduce methane emissions from its system by about 80 percent by accelerating the replacement of aging pipe, rehabilitating or retiring outdated infrastructure, and adopting new technologies and practices. The remaining emissions will likely be offset by purchasing and/or producing renewable natural gas. To date, Consumers has reduced methane emissions by more than 20 percent from a 2012 baseline.
In March 2022, Consumers also announced a net-zero greenhouse gas emissions target for its entire natural gas system by 2050. This includes suppliers and customers, and has an interim goal of reducing customer emissions by 20 percent by 2030. Consumers’ Natural Gas Delivery Plan, a 10-year strategic investment plan to deliver safe, reliable, clean, and affordable natural gas to customers, outlines ways in which Consumers can make early progress toward these goals in a cost-effective manner, including energy waste reduction or energy efficiency, carbon offsets, and renewable natural gas supply.
Consumers has already initiated work in these key areas, continuing to expand its energy waste reduction targets, launching a program allowing gas customers to purchase carbon offset credits on a voluntary basis, and announcing plans to begin development of a renewable natural gas facility that will capture methane from manure generated at a Michigan-based farm and convert it into renewable natural gas. Consumers is evaluating and monitoring newer technologies to determine their role in achieving Consumers’ interim and long-term net-zero goals, including hydrogen, biofuels, and synthetic methane; carbon capture sequestration systems; and other innovative technologies.
NorthStar Clean Energy Outlook and Uncertainties
CMS Energy’s primary focus with respect to its NorthStar Clean Energy businesses is to maximize the value of generating assets, its share of which represents 1,478 MW of capacity, and to pursue opportunities for the development of renewable generation projects.
NorthStar Clean Energy’s operations may be subject to various federal, state, and local environmental laws and regulations. Multiple environmental laws and regulations are subject to litigation. NorthStar

Clean Energy’s primary environmental compliance focus includes, but is not limited to, the following matters.
CSAPR requires Michigan and many other states to improve air quality by reducing power plant emissions that, according to EPA modeling, contribute to ground-level ozone in other downwind states. Since its 2015 effective date, CSAPR has been revised several times. In March 2023, the EPA finalized a revision to CSAPR affecting Michigan. This regulation establishes allowance budgets for electric generating units in 22 states, including Michigan, between 2023 and 2029 and changes the mechanism for allocating such allowances on a year-over-year basis beginning in 2026. NorthStar Clean Energy is evaluating this rule and its impact on NorthStar Clean Energy’s emission sources and may incur costs in allowance purchases or equipment retrofits.
In 2015, the EPA lowered the NAAQS for ozone and made it more difficult to construct or modify power plants and other emission sources in areas of the country that do not meet the ozone standard. In 2018, the EPA designated certain areas of Michigan as not meeting the ozone standard. Seven counties in southeastern Michigan were not in attainment with the ozone standard by a 2021 regulatory deadline and, in March 2023, had their ozone nonattainment designations increased from marginal to moderate. The DIG plant is within one of these counties and, as a result, may be subject to additional permitting restrictions in the event of any future increase in the nonattainment designation.
Many of NorthStar Clean Energy’s facilities maintain NPDES permits, which are vital to the facilities’ operations. NorthStar Clean Energy applies for renewal of these permits every five years. Failure of EGLE to renew any NPDES permit, a successful appeal against a permit, a change in the interpretation or scope of NPDES permitting, or onerous terms contained in a permit could have a significant detrimental effect on the operations of a facility.
For additional details regarding the new ozone NAAQS or CSAPR rule, see Consumers Electric Utility Outlook and Uncertainties—Electric Environmental Outlook.
Trends, uncertainties, and other matters related to NorthStar Clean Energy that could have a material impact on CMS Energy’s consolidated income, cash flows, or financial position include:
investment in and financial benefits received from renewable energy and energy storage projects
changes in energy and capacity prices
severe weather events and climate change associated with increasing levels of greenhouse gases
changes in commodity prices on certain derivative contracts that do not qualify for hedge accounting and must be marked to market through earnings
changes in various environmental laws, regulations, principles, or practices, or in their interpretation

In March 2022, the U.S. Department of Commerce announced it is opening inquiries into whether manufacturers of solar modules that are produced in certain countries using supplies obtained from China are circumventing antidumping and countervailing duties which apply to Chinese modules. The U.S. Department of Commerce has made an initial determination that four manufacturers have circumvented tariffs. The remainder of this inquiry process is continuing, with a final ruling expected in May 2023. In June 2022, the Biden Administration paused for two years the imposition of duties that might result from the U.S. Department of Commerce’s pending inquiries. In addition, the Uyghur Forced Labor Prevention Act, which was enacted in 2021 and became effective in June 2022, along with an earlier withhold release order that U.S. Customs and Border Protection issued in 2021, restrict the importation of goods sourced from the Xinjiang region of China. Solar modules whose raw materials come from the Xinjiang region are a key focus of these import laws. CMS Energy continues to closely monitor these matters and their potential impacts on availability of solar modules and timing associated with pending and planned solar projects.

Other Outlook and Uncertainties
Litigation: CMS Energy, Consumers, and certain of their subsidiaries are named as parties in various litigation matters, as well as in administrative proceedings before various courts and governmental agencies, arising in the ordinary course of business. For additional details regarding these and other legal matters, see Notes to the Unaudited Consolidated Financial Statements—Note 1, Regulatory Matters and Note 2, Contingencies and Commitments.
Employee Separation Program: In April 2023, CMS Energy and Consumers announced a voluntary separation program for non-union employees. Under the program, employees can elect to request separation, and management will decide which requests to accept. In May 2023, management will communicate its decisions to interested employees, who will have 45 days to decide whether to separate. The program is expected to result in recognition of additional expense in the second quarter of 2023; however, CMS Energy and Consumers expect to benefit from future cost savings, as employee staffing levels will be better aligned with business needs.
New Accounting Standards
There are no new accounting standards issued but not yet effective that are expected to have a material impact on CMS Energy’s or Consumers’ consolidated financial statements.
