Regulatory Matters

Regulatory Matters

Regulatory matters are critical to Consumers. The Michigan Attorney General, ABATE, the MPSC Staff, residential customer advocacy groups, environmental organizations, and certain other parties typically participate in MPSC proceedings concerning Consumers, such as Consumers’ rate cases and PSCR and GCR processes. These parties often challenge various aspects of those proceedings, including the prudence of Consumers’ policies and practices, and seek cost disallowances and other relief. The parties also have appealed significant MPSC orders. Depending upon the specific issues, the outcomes of rate cases and proceedings, including judicial proceedings challenging MPSC orders or other actions, could negatively affect CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations. Consumers cannot predict the outcome of these proceedings.

There are multiple appeals pending that involve various issues concerning cost recovery from customers, the MPSC’s authority to approve voluntary revenue refunds, and other matters. Consumers is unable to predict the outcome of these appeals.

Regulatory Assets and Liabilities

Consumers is subject to the actions of the MPSC and FERC and therefore prepares its consolidated financial statements in accordance with the provisions of regulatory accounting. A utility must apply regulatory accounting when its rates are designed to recover specific costs of providing regulated services. Under regulatory accounting, Consumers records regulatory assets or liabilities for certain transactions that would have been treated as expense or revenue by non‑regulated businesses.

Presented in the following table are the regulatory assets and liabilities on Consumers’ consolidated balance sheets:

1These regulatory assets have arisen from an alternative revenue program and are not associated with incurred costs or capital investments. Therefore, the MPSC has provided for recovery without a return.

2The MPSC has provided a specific return on these regulatory assets.

3This regulatory asset is included in rate base, thereby providing a return.

4These regulatory assets represent incurred costs for which the MPSC has provided recovery without a return on investment.

Regulatory Assets

Energy Waste Reduction Plan Incentive: The energy waste reduction incentive mechanism provides a financial incentive if the energy savings of Consumers’ customers exceed annual targets established by the MPSC. Consumers accounts for this program as an alternative-revenue program that meets the criteria for recognizing revenue related to the incentive as soon as energy savings exceed the annual targets established by the MPSC.

In October 2022, the MPSC approved a settlement agreement authorizing Consumers to collect $46 million during 2023 as an incentive for exceeding its statutory savings targets in 2021. Consumers recognized incentive revenue under this program of $46 million in 2021.

Consumers also exceeded its statutory savings targets in 2022, achieved certain other goals, and will request the MPSC’s approval to collect $55 million, the maximum performance incentive, in the energy waste reduction reconciliation to be filed in May 2023. Consumers recognized incentive revenue under this program of $55 million in 2022.

Costs of Coal-fueled Electric Generating Units to be Retired: In 2019, the MPSC approved the settlement agreement reached in Consumers’ 2018 IRP, under which Consumers will retire the D.E. Karn coal-fueled electric generating units in 2023. Under Michigan law, electric utilities have been permitted to use highly rated, low-cost securitization bonds to finance the recovery of qualified costs. In 2019, Consumers removed from total plant, property, and equipment an amount representing the projected remaining book value of the two coal-fueled electric generating units upon their retirement, and recorded it as a regulatory asset. In 2020, the MPSC issued a securitization financing order authorizing Consumers to issue securitization bonds in order to finance the recovery of the remaining book value of the two coal-fueled electric generating units upon their retirement. Until securitization, the book value of the generating units will remain in rate base and receive full regulatory returns in general rate cases.

In June 2022, the MPSC approved the settlement agreement reached in Consumers’ 2021 IRP, under which Consumers plans to retire the J.H. Campbell coal-fueled generating units in 2025. Under the 2021 IRP, upon the units’ retirement, Consumers will receive regulatory asset treatment to recover their remaining book value, as well as a 9.0‑percent return on equity, over their original design lives. Until retirement, the book value of the generating units will remain in rate base and receive full regulatory returns in general rate cases.

In June 2022, Consumers removed from total plant, property, and equipment an amount of $1.3 billion, representing the projected remaining book value of the electric generating units upon their retirement, and recorded it as a non-current regulatory asset on its consolidated balance sheets.

Postretirement Benefits: As part of the ratemaking process, the MPSC allows Consumers to recover the costs of postretirement benefits. Accordingly, Consumers defers the net impact of actuarial losses and gains, prior service costs and credits, and settlements associated with postretirement benefits as a regulatory asset or liability. The asset or liability will decrease as the deferred items are amortized and recognized as components of net periodic benefit cost. For details about settlements and the amortization periods, see Note 10, Retirement Benefits.

ARO: The recovery of the underlying asset investments and related removal and monitoring costs of recorded AROs is approved by the MPSC in depreciation rate cases. Consumers records a regulatory asset and a regulatory liability for timing differences between the recognition of AROs for financial reporting purposes and the recovery of these costs from customers. The recovery period approximates the useful life of the assets to be removed.

Securitized Costs: In 2013, the MPSC issued a securitization financing order authorizing Consumers to issue securitization bonds in order to finance the recovery of the remaining book value of seven smaller coal-fueled electric generating units that Consumers retired in 2016 and three smaller natural gas-fueled electric generating units that Consumers retired in 2015. Upon receipt of the MPSC’s order, Consumers removed the book value of the ten units from plant, property, and equipment and recorded this amount as a regulatory asset. Consumers is amortizing the regulatory asset over the life of the related securitization bonds, which it issued through a subsidiary in 2014. For additional details regarding the securitization bonds, see Note 4, Financings and Capitalization.

MGP Sites: Consumers is incurring environmental remediation and other response activity costs at 23 former MGP facilities. The MPSC allows Consumers to recover from its natural gas customers over a ten-year period the costs incurred to remediate the MGP sites.

Unamortized Loss on Reacquired Debt: Under regulatory accounting, any unamortized discount, premium, or expense related to debt redeemed with the proceeds of new debt is capitalized and amortized over the life of the new debt.

Retention Incentive Program: To ensure necessary staffing at the D.E. Karn and J.H. Campbell generating complexes through the anticipated retirement of the coal-fueled generating units, Consumers has established retention incentive programs. In 2020, the MPSC approved deferred accounting treatment for the retention and severance costs incurred under the D.E. Karn program, and Consumers began deferring these costs as a regulatory asset in 2021. In addition, under the 2021 IRP, the MPSC approved deferred accounting treatment for the retention and severance costs incurred under the J.H. Campbell program during 2022; deferral of costs beyond 2022 was approved as part of the 2022 electric rate case settlement. For additional details regarding the retention incentive program, see Note 19, Exit Activities and Discontinued Operations.

Demand Response Program: In Consumers’ 2018 IRP and general rate cases, the MPSC has approved the recovery of demand response costs. Consumers annually files a reconciliation with the MPSC to review actual demand response costs against amounts approved. The amount of spending incurred in excess of amounts included in rates for recovery is recorded as a regulatory asset and amortized when it is collected from customers. The amount included in rates for recovery in excess of spending incurred is recorded as a regulatory liability to be refunded to customers.

Energy Waste Reduction Plan: The MPSC allows Consumers to collect surcharges from customers to fund its energy waste reduction plan. The amount of spending incurred in excess of surcharges collected is recorded as a regulatory asset and amortized as surcharges are collected from customers over the plan period. The amount of surcharges collected in excess of spending incurred is recorded as a regulatory liability and amortized as costs are incurred.

Regulatory Liabilities

Income Taxes, Net: Consumers records regulatory assets and liabilities to reflect the difference between deferred income taxes recognized for financial reporting purposes and amounts previously reflected in Consumers’ rates. This net balance will decrease over the remaining life of the related temporary differences and flow through income tax expense. The majority of the net regulatory liability recorded

related to income taxes is associated with plant assets that are subject to normalization, which is governed by the Internal Revenue Code, and will be returned to customers over the remaining book life of the related plant assets. For additional details on deferred income taxes, see Note 12, Income Taxes.

Reserve for Customer Refunds: In December 2022, the MPSC issued an order authorizing Consumers to refund $22 million voluntarily to utility customers. In January 2023, Consumers submitted a filing proposing that the refund take the form of incremental funding to cover the cost of, and return on, certain distribution capital investments above amounts included in rates and contributions to programs that assist vulnerable customers.

Additionally, in the settlement of its 2022 electric rate case, Consumers agreed to refund voluntarily $15 million of 2022 revenues to utility customers through a one-time bill credit and to fund $10 million in contributions to programs that directly assist vulnerable customers with utility bills.

Cost of Removal: The MPSC allows Consumers to collect amounts from customers to fund future asset removal activities. This regulatory liability is reduced as costs are incurred to remove the assets at the end of their useful lives.

Renewable Energy Grant: In 2013, Consumers received a $69 million renewable energy grant for Lake Winds® Energy Park, which began operations in 2012. This grant reduces Consumers’ cost of complying with Michigan’s renewable portfolio standard and, accordingly, reduces the overall renewable energy surcharge to be collected from customers. The regulatory liability recorded for the grant will be amortized over the life of Lake Winds® Energy Park.

Renewable Energy Plan: Consumers has collected surcharges to fund its renewable energy plan. Amounts not yet spent under the plan are recorded as a regulatory liability, which is amortized as incremental costs are incurred to operate and depreciate Consumers’ renewable generation facilities and to purchase RECs under renewable energy purchase agreements. Incremental costs represent costs incurred in excess of amounts recovered through the PSCR process.

Consumers Electric Utility

2021 Electric Rate Case: In December 2021, the MPSC issued a final order in Consumers’ 2021 electric rate case, disallowing cost recovery for fleet assets and certain other categories of recently completed capital expenditures incurred by Consumers. As a result, Consumers impaired certain of these capital expenditures, a portion of which were held by the gas utility, and recorded impairment charges totaling $45 million within maintenance and other operating expenses on its consolidated statements of income for the year ended December 31, 2021.

2022 Electric Rate Case: In April 2022, Consumers filed an application with the MPSC seeking a rate increase of $272 million, based on a 10.25-percent authorized return on equity for the projected twelve-month period ending December 31, 2023. In September 2022, Consumers revised its requested increase to $292 million. The filing requested authority to recover future investments associated with distribution system reliability, solar generation, environmental compliance, and enhanced technology.

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. Additionally, the approved settlement provides for the following:

•a pension and OPEB tracker that will allow Consumers to defer the future recovery or refund of pension and OPEB expenses above or below the amounts used to set existing rates, respectively

•a refund of $15 million of 2022 revenues to utility customers through a one-time bill credit

•a commitment to fund $10 million in contributions to programs that directly assist vulnerable customers with utility bills

•deferred accounting treatment for depreciation and property tax expense as well as the debt component of the overall rate of return for distribution-related capital investments exceeding a certain threshold amount

•an increase to the distributed generation cap from two percent to four percent on Consumers’ system

There were no direct disallowances of historical capital expenditures within the approved settlement agreement. The new rates became effective January 20, 2023.

Voluntary Radio Tower Asset Sale Gain Share: In May 2022, Consumers completed a sale of various radio tower assets. In June 2022, Consumers filed an application with the MPSC requesting approval to share voluntarily half of the gain from the sale with its electric and gas utility customers; this application was approved by the MPSC in October 2022. During 2022, Consumers shared two-thirds with electric customers through additional spending for tree trimming and one-third with gas customers through a donation to nonprofit agencies that provide customer energy bill assistance.

Consumers Gas Utility

2021 Gas Rate Case: In December 2021, Consumers filed an application with the MPSC seeking an annual rate increase of $278 million, based on a 10.5-percent authorized return on equity for the projected twelve-month period ending September 30, 2023. In April 2022, Consumers reduced its requested annual rate increase to $233 million, based on a 10.25-percent authorized return on equity. In July 2022, the MPSC approved a settlement agreement authorizing an annual rate increase of $170 million, based on a 9.9-percent authorized return on equity, effective October 1, 2022. The MPSC also approved the continuation of a revenue decoupling mechanism, which annually reconciles Consumers’ actual weather-normalized non-fuel revenues with the revenues approved.

Power Supply Cost Recovery and Gas Cost Recovery

The PSCR and GCR ratemaking processes are designed to allow Consumers to recover all of its power supply and purchased natural gas costs if incurred under reasonable and prudent policies and practices. The MPSC reviews these costs, policies, and practices in annual plan and reconciliation proceedings. Consumers adjusts its PSCR and GCR billing charges monthly, subject to ceiling factor limitations, in order to minimize the underrecovery or overrecovery amount in the annual reconciliations. Underrecoveries represent probable future revenues that will be recovered from customers; overrecoveries represent previously collected revenues that will be refunded to customers.

Presented in the following table are the assets and liabilities for PSCR and GCR underrecoveries and overrecoveries reflected on Consumers’ consolidated balance sheets:

In Millions
December 31	2022			2021
Assets
PSCR underrecoveries		$	401		$	—
GCR underrecoveries		8			25
Accounts receivable and accrued revenue		$	409		$	25
Liabilities
PSCR overrecoveries		$	—		$	12
Accrued rate refunds		$	—		$	12

Due to spikes in fuel prices during 2022, the cost of electric generation increased, resulting in higher market prices for electricity. Accordingly, Consumers’ power supply costs for 2022 were significantly higher than those projected in its 2022 PSCR plan. Consumers included a projection of its full-year 2022 underrecovery in the 2023 PSCR plan filed with the MPSC in September 2022. In January 2023, Consumers filed a motion for a temporary order in its 2023 PSCR plan, requesting that the MPSC approve only a third of the 2022 underrecovery amount for recovery in 2023, with the remaining amount to be recovered equally during 2024 and 2025. Recovering the 2022 underrecovery over three years will provide immediate relief to electric customers, and the financial impact will be neutral to Consumers’ earnings.

PSCR Plans and Reconciliations: In August 2022, the MPSC issued an order in Consumers’ 2020 PSCR reconciliation, authorizing recovery of $1.8 billion of power costs and authorizing Consumers to reflect in its 2021 PSCR reconciliation the underrecovery of $1 million. In its order, the MPSC disallowed the recovery of $1 million of replacement power costs associated with an extended outage at Ludington. Consumers filed an appeal of the MPSC’s order with the Michigan Court of Appeals in September 2022.

In March 2022, Consumers filed its 2021 PSCR reconciliation, requesting full recovery of $2.1 billion of power costs and authorization to reflect in its 2022 PSCR reconciliation the overrecovery of $8 million.

Consumers submitted its 2022 PSCR plan to the MPSC in September 2021 and self-implemented its proposed 2022 PSCR charge in January 2022.

GCR Plans and Reconciliations: In April 2022, the MPSC approved a settlement agreement in Consumers’ 2020-2021 GCR reconciliation, authorizing recovery of $0.4 billion of gas costs and authorizing Consumers to reflect in its 2021-2022 GCR reconciliation the overrecovery of $2 million.

In June 2022, Consumers filed its 2021-2022 GCR reconciliation, requesting full recovery of $0.7 billion of gas costs and authorization to reflect in its 2022-2023 GCR reconciliation the underrecovery of $9 million.

Consumers submitted its 2022-2023 GCR plan to the MPSC in December 2021 and self-implemented its proposed 2022-2023 GCR charge in April 2022. In June 2022, Consumers filed with the MPSC a revised GCR plan requesting an increase to the GCR factor due to rising natural gas prices. Consumers self-implemented that increased factor in October 2022.

Regulatory Matters

Regulatory matters are critical to Consumers. The Michigan Attorney General, ABATE, the MPSC Staff, residential customer advocacy groups, environmental organizations, and certain other parties typically participate in MPSC proceedings concerning Consumers, such as Consumers’ rate cases and PSCR and GCR processes. These parties often challenge various aspects of those proceedings, including the prudence of Consumers’ policies and practices, and seek cost disallowances and other relief. The parties also have appealed significant MPSC orders. Depending upon the specific issues, the outcomes of rate cases and proceedings, including judicial proceedings challenging MPSC orders or other actions, could negatively affect CMS Energy’s and Consumers’ liquidity, financial condition, and results of operations. Consumers cannot predict the outcome of these proceedings.

There are multiple appeals pending that involve various issues concerning cost recovery from customers, the MPSC’s authority to approve voluntary revenue refunds, and other matters. Consumers is unable to predict the outcome of these appeals.

Regulatory Assets and Liabilities

Consumers is subject to the actions of the MPSC and FERC and therefore prepares its consolidated financial statements in accordance with the provisions of regulatory accounting. A utility must apply regulatory accounting when its rates are designed to recover specific costs of providing regulated services. Under regulatory accounting, Consumers records regulatory assets or liabilities for certain transactions that would have been treated as expense or revenue by non‑regulated businesses.

1These regulatory assets have arisen from an alternative revenue program and are not associated with incurred costs or capital investments. Therefore, the MPSC has provided for recovery without a return.

2The MPSC has provided a specific return on these regulatory assets.

3This regulatory asset is included in rate base, thereby providing a return.

4These regulatory assets represent incurred costs for which the MPSC has provided recovery without a return on investment.

Regulatory Assets

Energy Waste Reduction Plan Incentive: The energy waste reduction incentive mechanism provides a financial incentive if the energy savings of Consumers’ customers exceed annual targets established by the MPSC. Consumers accounts for this program as an alternative-revenue program that meets the criteria for recognizing revenue related to the incentive as soon as energy savings exceed the annual targets established by the MPSC.

In October 2022, the MPSC approved a settlement agreement authorizing Consumers to collect $46 million during 2023 as an incentive for exceeding its statutory savings targets in 2021. Consumers recognized incentive revenue under this program of $46 million in 2021.

Consumers also exceeded its statutory savings targets in 2022, achieved certain other goals, and will request the MPSC’s approval to collect $55 million, the maximum performance incentive, in the energy waste reduction reconciliation to be filed in May 2023. Consumers recognized incentive revenue under this program of $55 million in 2022.

Costs of Coal-fueled Electric Generating Units to be Retired: In 2019, the MPSC approved the settlement agreement reached in Consumers’ 2018 IRP, under which Consumers will retire the D.E. Karn coal-fueled electric generating units in 2023. Under Michigan law, electric utilities have been permitted to use highly rated, low-cost securitization bonds to finance the recovery of qualified costs. In 2019, Consumers removed from total plant, property, and equipment an amount representing the projected remaining book value of the two coal-fueled electric generating units upon their retirement, and recorded it as a regulatory asset. In 2020, the MPSC issued a securitization financing order authorizing Consumers to issue securitization bonds in order to finance the recovery of the remaining book value of the two coal-fueled electric generating units upon their retirement. Until securitization, the book value of the generating units will remain in rate base and receive full regulatory returns in general rate cases.

In June 2022, the MPSC approved the settlement agreement reached in Consumers’ 2021 IRP, under which Consumers plans to retire the J.H. Campbell coal-fueled generating units in 2025. Under the 2021 IRP, upon the units’ retirement, Consumers will receive regulatory asset treatment to recover their remaining book value, as well as a 9.0‑percent return on equity, over their original design lives. Until retirement, the book value of the generating units will remain in rate base and receive full regulatory returns in general rate cases.

In June 2022, Consumers removed from total plant, property, and equipment an amount of $1.3 billion, representing the projected remaining book value of the electric generating units upon their retirement, and recorded it as a non-current regulatory asset on its consolidated balance sheets.

Postretirement Benefits: As part of the ratemaking process, the MPSC allows Consumers to recover the costs of postretirement benefits. Accordingly, Consumers defers the net impact of actuarial losses and gains, prior service costs and credits, and settlements associated with postretirement benefits as a regulatory asset or liability. The asset or liability will decrease as the deferred items are amortized and recognized as components of net periodic benefit cost. For details about settlements and the amortization periods, see Note 10, Retirement Benefits.

ARO: The recovery of the underlying asset investments and related removal and monitoring costs of recorded AROs is approved by the MPSC in depreciation rate cases. Consumers records a regulatory asset and a regulatory liability for timing differences between the recognition of AROs for financial reporting purposes and the recovery of these costs from customers. The recovery period approximates the useful life of the assets to be removed.

Securitized Costs: In 2013, the MPSC issued a securitization financing order authorizing Consumers to issue securitization bonds in order to finance the recovery of the remaining book value of seven smaller coal-fueled electric generating units that Consumers retired in 2016 and three smaller natural gas-fueled electric generating units that Consumers retired in 2015. Upon receipt of the MPSC’s order, Consumers removed the book value of the ten units from plant, property, and equipment and recorded this amount as a regulatory asset. Consumers is amortizing the regulatory asset over the life of the related securitization bonds, which it issued through a subsidiary in 2014. For additional details regarding the securitization bonds, see Note 4, Financings and Capitalization.

MGP Sites: Consumers is incurring environmental remediation and other response activity costs at 23 former MGP facilities. The MPSC allows Consumers to recover from its natural gas customers over a ten-year period the costs incurred to remediate the MGP sites.

Unamortized Loss on Reacquired Debt: Under regulatory accounting, any unamortized discount, premium, or expense related to debt redeemed with the proceeds of new debt is capitalized and amortized over the life of the new debt.

Retention Incentive Program: To ensure necessary staffing at the D.E. Karn and J.H. Campbell generating complexes through the anticipated retirement of the coal-fueled generating units, Consumers has established retention incentive programs. In 2020, the MPSC approved deferred accounting treatment for the retention and severance costs incurred under the D.E. Karn program, and Consumers began deferring these costs as a regulatory asset in 2021. In addition, under the 2021 IRP, the MPSC approved deferred accounting treatment for the retention and severance costs incurred under the J.H. Campbell program during 2022; deferral of costs beyond 2022 was approved as part of the 2022 electric rate case settlement. For additional details regarding the retention incentive program, see Note 19, Exit Activities and Discontinued Operations.

Demand Response Program: In Consumers’ 2018 IRP and general rate cases, the MPSC has approved the recovery of demand response costs. Consumers annually files a reconciliation with the MPSC to review actual demand response costs against amounts approved. The amount of spending incurred in excess of amounts included in rates for recovery is recorded as a regulatory asset and amortized when it is collected from customers. The amount included in rates for recovery in excess of spending incurred is recorded as a regulatory liability to be refunded to customers.

Energy Waste Reduction Plan: The MPSC allows Consumers to collect surcharges from customers to fund its energy waste reduction plan. The amount of spending incurred in excess of surcharges collected is recorded as a regulatory asset and amortized as surcharges are collected from customers over the plan period. The amount of surcharges collected in excess of spending incurred is recorded as a regulatory liability and amortized as costs are incurred.

Regulatory Liabilities

Income Taxes, Net: Consumers records regulatory assets and liabilities to reflect the difference between deferred income taxes recognized for financial reporting purposes and amounts previously reflected in Consumers’ rates. This net balance will decrease over the remaining life of the related temporary differences and flow through income tax expense. The majority of the net regulatory liability recorded

related to income taxes is associated with plant assets that are subject to normalization, which is governed by the Internal Revenue Code, and will be returned to customers over the remaining book life of the related plant assets. For additional details on deferred income taxes, see Note 12, Income Taxes.

Reserve for Customer Refunds: In December 2022, the MPSC issued an order authorizing Consumers to refund $22 million voluntarily to utility customers. In January 2023, Consumers submitted a filing proposing that the refund take the form of incremental funding to cover the cost of, and return on, certain distribution capital investments above amounts included in rates and contributions to programs that assist vulnerable customers.

Additionally, in the settlement of its 2022 electric rate case, Consumers agreed to refund voluntarily $15 million of 2022 revenues to utility customers through a one-time bill credit and to fund $10 million in contributions to programs that directly assist vulnerable customers with utility bills.

Cost of Removal: The MPSC allows Consumers to collect amounts from customers to fund future asset removal activities. This regulatory liability is reduced as costs are incurred to remove the assets at the end of their useful lives.

Renewable Energy Grant: In 2013, Consumers received a $69 million renewable energy grant for Lake Winds® Energy Park, which began operations in 2012. This grant reduces Consumers’ cost of complying with Michigan’s renewable portfolio standard and, accordingly, reduces the overall renewable energy surcharge to be collected from customers. The regulatory liability recorded for the grant will be amortized over the life of Lake Winds® Energy Park.

Renewable Energy Plan: Consumers has collected surcharges to fund its renewable energy plan. Amounts not yet spent under the plan are recorded as a regulatory liability, which is amortized as incremental costs are incurred to operate and depreciate Consumers’ renewable generation facilities and to purchase RECs under renewable energy purchase agreements. Incremental costs represent costs incurred in excess of amounts recovered through the PSCR process.

Consumers Electric Utility

2021 Electric Rate Case: In December 2021, the MPSC issued a final order in Consumers’ 2021 electric rate case, disallowing cost recovery for fleet assets and certain other categories of recently completed capital expenditures incurred by Consumers. As a result, Consumers impaired certain of these capital expenditures, a portion of which were held by the gas utility, and recorded impairment charges totaling $45 million within maintenance and other operating expenses on its consolidated statements of income for the year ended December 31, 2021.

2022 Electric Rate Case: In April 2022, Consumers filed an application with the MPSC seeking a rate increase of $272 million, based on a 10.25-percent authorized return on equity for the projected twelve-month period ending December 31, 2023. In September 2022, Consumers revised its requested increase to $292 million. The filing requested authority to recover future investments associated with distribution system reliability, solar generation, environmental compliance, and enhanced technology.

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. Additionally, the approved settlement provides for the following:

•a pension and OPEB tracker that will allow Consumers to defer the future recovery or refund of pension and OPEB expenses above or below the amounts used to set existing rates, respectively

•a refund of $15 million of 2022 revenues to utility customers through a one-time bill credit

•a commitment to fund $10 million in contributions to programs that directly assist vulnerable customers with utility bills

•deferred accounting treatment for depreciation and property tax expense as well as the debt component of the overall rate of return for distribution-related capital investments exceeding a certain threshold amount

•an increase to the distributed generation cap from two percent to four percent on Consumers’ system

There were no direct disallowances of historical capital expenditures within the approved settlement agreement. The new rates became effective January 20, 2023.

Voluntary Radio Tower Asset Sale Gain Share: In May 2022, Consumers completed a sale of various radio tower assets. In June 2022, Consumers filed an application with the MPSC requesting approval to share voluntarily half of the gain from the sale with its electric and gas utility customers; this application was approved by the MPSC in October 2022. During 2022, Consumers shared two-thirds with electric customers through additional spending for tree trimming and one-third with gas customers through a donation to nonprofit agencies that provide customer energy bill assistance.

Consumers Gas Utility

2021 Gas Rate Case: In December 2021, Consumers filed an application with the MPSC seeking an annual rate increase of $278 million, based on a 10.5-percent authorized return on equity for the projected twelve-month period ending September 30, 2023. In April 2022, Consumers reduced its requested annual rate increase to $233 million, based on a 10.25-percent authorized return on equity. In July 2022, the MPSC approved a settlement agreement authorizing an annual rate increase of $170 million, based on a 9.9-percent authorized return on equity, effective October 1, 2022. The MPSC also approved the continuation of a revenue decoupling mechanism, which annually reconciles Consumers’ actual weather-normalized non-fuel revenues with the revenues approved.

Power Supply Cost Recovery and Gas Cost Recovery

The PSCR and GCR ratemaking processes are designed to allow Consumers to recover all of its power supply and purchased natural gas costs if incurred under reasonable and prudent policies and practices. The MPSC reviews these costs, policies, and practices in annual plan and reconciliation proceedings. Consumers adjusts its PSCR and GCR billing charges monthly, subject to ceiling factor limitations, in order to minimize the underrecovery or overrecovery amount in the annual reconciliations. Underrecoveries represent probable future revenues that will be recovered from customers; overrecoveries represent previously collected revenues that will be refunded to customers.

Presented in the following table are the assets and liabilities for PSCR and GCR underrecoveries and overrecoveries reflected on Consumers’ consolidated balance sheets:

In Millions
December 31	2022			2021
Assets
PSCR underrecoveries		$	401		$	—
GCR underrecoveries		8			25
Accounts receivable and accrued revenue		$	409		$	25
Liabilities
PSCR overrecoveries		$	—		$	12
Accrued rate refunds		$	—		$	12

Due to spikes in fuel prices during 2022, the cost of electric generation increased, resulting in higher market prices for electricity. Accordingly, Consumers’ power supply costs for 2022 were significantly higher than those projected in its 2022 PSCR plan. Consumers included a projection of its full-year 2022 underrecovery in the 2023 PSCR plan filed with the MPSC in September 2022. In January 2023, Consumers filed a motion for a temporary order in its 2023 PSCR plan, requesting that the MPSC approve only a third of the 2022 underrecovery amount for recovery in 2023, with the remaining amount to be recovered equally during 2024 and 2025. Recovering the 2022 underrecovery over three years will provide immediate relief to electric customers, and the financial impact will be neutral to Consumers’ earnings.

PSCR Plans and Reconciliations: In August 2022, the MPSC issued an order in Consumers’ 2020 PSCR reconciliation, authorizing recovery of $1.8 billion of power costs and authorizing Consumers to reflect in its 2021 PSCR reconciliation the underrecovery of $1 million. In its order, the MPSC disallowed the recovery of $1 million of replacement power costs associated with an extended outage at Ludington. Consumers filed an appeal of the MPSC’s order with the Michigan Court of Appeals in September 2022.

In March 2022, Consumers filed its 2021 PSCR reconciliation, requesting full recovery of $2.1 billion of power costs and authorization to reflect in its 2022 PSCR reconciliation the overrecovery of $8 million.

Consumers submitted its 2022 PSCR plan to the MPSC in September 2021 and self-implemented its proposed 2022 PSCR charge in January 2022.

GCR Plans and Reconciliations: In April 2022, the MPSC approved a settlement agreement in Consumers’ 2020-2021 GCR reconciliation, authorizing recovery of $0.4 billion of gas costs and authorizing Consumers to reflect in its 2021-2022 GCR reconciliation the overrecovery of $2 million.

In June 2022, Consumers filed its 2021-2022 GCR reconciliation, requesting full recovery of $0.7 billion of gas costs and authorization to reflect in its 2022-2023 GCR reconciliation the underrecovery of $9 million.

Consumers submitted its 2022-2023 GCR plan to the MPSC in December 2021 and self-implemented its proposed 2022-2023 GCR charge in April 2022. In June 2022, Consumers filed with the MPSC a revised GCR plan requesting an increase to the GCR factor due to rising natural gas prices. Consumers self-implemented that increased factor in October 2022.
