Rate Plans

The Utilities provide service to New York customers according to the terms of tariffs approved by the NYSPSC. Tariffs for service to customers of Rockland Electric Company (RECO), O&R’s New Jersey regulated utility subsidiary, are approved by the New Jersey Board of Public Utilities (NJBPU). The tariffs include schedules of rates for service that limit the rates charged by the Utilities to amounts that the Utilities recover from their customers costs approved by the regulator, including capital costs, of providing service to customers as defined by the tariff. The tariffs implement rate plans adopted by state utility regulators in rate orders issued at the conclusion of rate proceedings. Pursuant to the Utilities’ rate plans, there generally can be no change to the charges to customers during the respective terms of the rate plans other than specified adjustments provided for in the rate plans. The Utilities’ rate plans each cover specified periods, but rates determined pursuant to a plan generally continue in effect until a new rate plan is approved by the state utility regulator.

Common provisions of the Utilities’ New York rate plans include:

Base Rates are designed to recover core costs of providing electric, gas or steam delivery service such as the costs of constructing, operating and maintaining a service’s system.

Earnings sharing that require the Utilities to defer for customer benefit a portion of earnings over specified rates of return on common equity. There is no symmetric mechanism for earnings below specified rates of return on common equity.

Negative revenue adjustments for failure to meet certain performance standards relating to service, reliability, safety and other matters.

Net utility plant reconciliations that require deferral as a regulatory liability of the revenue requirement impact of the amount, if any, by which actual average net utility plant balances are less than amounts reflected in rates. There is generally no symmetric mechanism if actual average net utility plant balances are more than amounts reflected in rates.

Other revenue adjustments that represent positive revenue adjustments, positive incentives, and earnings adjustments mechanisms for achievement of performance standards related to achievement of clean energy goals, safety and other matters.

Rate base, as reflected in the rate plans, is, in general, the sum of the Utilities’ net plant, working capital and certain regulatory assets less deferred taxes and certain regulatory liabilities. For each rate plan, the NYSPSC uses a forecast of the average rate base for each year that new rates would be in effect (“rate year”).

Recoverable energy costs that allow the Utilities to recover on a current basis the costs for the energy they supply with no mark-up to their full-service customers.

Regulatory reconciliations that reconcile pension and other postretirement benefit costs, environmental remediation costs, property taxes, variable-rate tax-exempt debt and certain other costs (including late payment charges and write-offs of customer accounts receivable balances) to amounts reflected in delivery rates for such costs. In addition, changes in the Utilities' costs not reflected in rates, in excess of certain amounts, resulting from changes in tax or changes in legislation, regulation or related actions, are deferred as a regulatory asset or regulatory liability to be reflected in the Utilities' next rate plan or in a manner to be determined by the NYSPSC. Also, the Utilities generally retain the right to petition for recovery or accounting deferral of extraordinary and material cost increases and provision is sometimes made for the utility to retain a share of cost reductions, for example, property tax refunds.

Revenue decoupling mechanisms that reconcile actual energy delivery revenues to the authorized delivery revenues approved by the NYSPSC. The difference is accrued with interest for refund to, or recovery from customers, as applicable.

Weighted average cost of capital is determined based on the authorized common equity ratio, return on common equity, cost of long-term debt and cost of customer deposits reflected in each rate plan. For each rate plan, the revenues designed to provide the utility a return on invested capital for each rate year are determined by multiplying each utility rate base by its pre–tax weighted average cost of capital. The Utilities’ actual return on common equity will reflect their actual operations for each rate year, and may be more or less than the authorized return on equity reflected in their rate plans (and if more, may be subject to earnings sharing).

(e)In general, if actual expenses for municipal infrastructure support (other than company labor) are below the amounts reflected in rates the company will defer the difference for credit to customers, and if the actual expenses are above the amount reflected in rates the company will defer for recovery from customers 80 percent of the difference subject to a maximum deferral, subject to certain conditions, of 15 percent of the amount reflected in the rate plans.

(f)In addition, the NYSPSC continues its focused operations audit to investigate CECONY's financial accounting for income taxes. Any NYSPSC ordered adjustment to CECONY’s financial accounting for income taxes is expected to be refunded to or collected from customers, as determined by the NYSPSC. See "Other Regulatory Matters," below.

(g)Reconciliation of net utility plant for AMI will be done on a combined basis for electric and gas.

(h)Calculated in accordance with the earnings calculation method prescribed in the rate order.

(i)In November 2021, the NYSPSC issued an order that allowed CECONY to recover $43 million of late payment charges and fees that were not billed for the year ended December 31, 2020. The recalculated return on equity for 2020 which reflects the recovery of these fees is 8.81 percent.

(j)Amounts reflect amortization of the TCJA allocable to CECONY’s electric customers ($256 million) over a two-year period ($128 million in Yr. 1 and Yr. 2), the protected portion of the regulatory liability for excess deferred income taxes allocable to CECONY’s electric customers ($1,512 million) over the remaining lives of the related assets ($34 million in Yr. 1, $63 million in Yr. 2, and $34 million in Yr. 3) and the unprotected portion of the net regulatory liability ($306 million) over two years ($153 million annually). Amounts also reflect amortization of the regulatory asset for deferred MTA power reliability costs ($93 million) over a three-year period ($31 million annually).

In April 2023, the NYSPSC approved CECONY’s December 2022 petition seeking cost recovery approval for a proposed clean energy hub in Brooklyn, New York (Brooklyn Clean Energy Hub). The Brooklyn Clean Energy Hub primarily addresses an identified reliability need in 2028 due to a forecasted increase in electric demand. Construction began in September 2023 and is expected to be completed by 2028. CECONY’s January 2025 electric rate case filing reflected the costs for the Brooklyn Clean Energy Hub in base rates.

In January 2024, the NYSPSC approved CECONY's August 2023 petition requesting authorization and cost recovery to construct two new substations in Jamaica, Queens (Idlewild Project) that is in addition to the capital expenditures approved in CECONY's 2023 - 2025 electric rate plan summarized above. The project is expected to be completed by May 2028 to meet anticipated reliability needs and to support New York State’s Climate Leadership and Community Protection Act goals. CECONY estimates that construction will cost $1,200 million. CECONY's January 2025 electric rate case filing reflected the costs for the Idlewild Project in base rates.

In January 2025, CECONY filed a request with the NYSPSC for an electric rate increase of $1,612 million, effective January 1, 2026. The filing reflects a return on common equity of 10.1 percent and a common equity ratio of 48 percent.

The company is requesting provisions pursuant to which expenses for pension and other post-retirement benefits, long-term debt, storm restoration, property taxes, municipal infrastructure support, the impact of new laws, late payment charges, and environmental site investigation and remediation are reconciled to amounts reflected in rates. In addition, the company is proposing a continued reconciliation and current recovery or surcharge mechanism of uncollectible write-offs to the level in rates. The company is proposing the continuation of earnings opportunities from Earnings Adjustment Mechanisms for meeting energy efficiency goals. The filing also reflects continuation of the revenue decoupling mechanism and the provisions pursuant to which the company recovers its purchased power and fuel costs from customers.

The filing includes supplemental information regarding electric rate plans for 2027 and 2028, which the company is not requesting, but would consider through settlement discussions. For purposes of illustration, rate increases of $932 million and $880 million effective January 2027 and 2028, respectively, were calculated based upon an assumed return on common equity of 10.1 percent and a common equity ratio of 48 percent.

Earnings sharing	Weather normalized earnings above an annual earnings threshold of 9.9 percent are to be applied to reduce regulatory assets for environmental remediation and other costs. In 2014, the company had no earnings above the threshold. Actual earnings were $11.5 million and $7.8 million above the threshold in 2015 and 2016, respectively. In 2017, actual earnings were $8.5 million above the threshold, offset in part by a positive adjustment related to 2016 of $4 million. In 2018, actual earnings were $16.5 million above the threshold, and an additional $1.1 million related to 2017 was recorded. In 2019 actual earnings were $5 million above the threshold, offset in part by an adjustment related to 2018 of $2.3 million. In 2020, 2021, 2022 and 2023, the company had no earnings sharing above the threshold. Reserve adjustments of $0.4 million and $0.2 million were recorded in 2021 related to potential adjustment to the excess earnings sharing amounts for 2016 and 2018, respectively.	Most earnings above an annual earnings threshold of 9.75 percent are to be applied to reduce regulatory assets for environmental remediation and other costs accumulated in the rate year. There were no earnings above the threshold in Yr. 1.

(a)The base rate increases will be implemented with increases of $77.8 million in Yr. 1; $77.8 million in Yr. 2; and $77.8 million in Yr. 3 to levelize the customer bill impact. New rates were effective as of November 1, 2023. CECONY began billing customers at the new levelized rate in December 2023.

(b)Amounts reflect amortization of the tax savings under the federal Tax Cuts and Jobs Act of 2017 (TCJA) for the unprotected portion of the regulatory liability for excess deferred income taxes allocable to CECONY’s steam customers (the entire $24 million in Yr.1), the protected portion of the regulatory liability for excess deferred income taxes allocable to CECONY’s steam customers over the remaining lives of the related assets ($3 million in Yr. 1; $5 million in Yr. 2; and $6 million in Yr. 3) and the non-plant portion of the regulatory asset for deficient deferred income taxes allocable to CECONY’s steam customers (the entire $11 million in Yr.1).

(c)CECONY will defer the difference between its actual write-offs of uncollectible expenses and late payment fees (from January 1, 2020 through October 31, 2026) to amounts reflected in rates, with recovery/refund from or to customers via surcharge/sur-credit. Surcharge recoveries for write-offs of uncollectible expenses and late payment fees will each be subject to an annual cap that produces no more than a half percent (0.5 percent) total customer bill impact (estimated to be $2.5 million, $3.0 million, $3.5 million for Yr. 1, Yr. 2 and Yr. 3, respectively). Amounts in excess of the annual surcharge cap in a specific year may be rolled forward for recovery and will count towards the following year’s surcharge cap. Amounts in excess of the surcharge cap will be deferred as a regulatory asset for recovery in CECONY’s next steam base rate case.

(d)Deferrals for property taxes are limited to 90 percent of the difference from amounts reflected in rates, subject to an annual maximum for the remaining difference of not more than a maximum number of basis points impact on return on common equity (Yr. 1 – 10.0 basis points; Yr. 2 – 7.5 basis points; and Yr. 3 – 5.0 basis points), with recovery/refund from or to customers via surcharge/sur-credit. Surcharge recoveries will be subject to an annual cap that produces no more than a half percent (0.5 percent) total customer bill impact (estimated to be $2.5 million, $3.0 million, $3.5 million for Yr. 1, Yr. 2 and Yr. 3, respectively). Amounts in excess of the annual surcharge cap in a specific year may be rolled forward for recovery and will count towards the following year’s surcharge cap. Amounts in excess of the surcharge cap will be deferred as a regulatory asset for recovery in CECONY’s next steam base rate case.

(e)In general, if actual expenses for municipal infrastructure support (other than company labor) are below the amounts reflected in rates, CECONY will defer the difference for credit to customers, and if the actual expenses are above the amount reflected in rates, CECONY will defer for recovery from customers 80 percent of the difference subject to a maximum deferral, subject to certain conditions, of 30 percent of the amount reflected in the rate plan.

(f)In addition, the NYSPSC continues its focused operations audit to investigate CECONY's financial accounting for income taxes. Any NYSPSC ordered adjustment to CECONY’s financial accounting for income taxes is expected to be refunded to or collected from customers, as determined by the NYSPSC. See "Other Regulatory Matters," below.

(g)Rates determined pursuant to this rate plan were in effect until October 31, 2023. 2023 or Yr. 10 represents a partial year commencing January 1, 2023 through October 31, 2023.

(h)The impact of these base rate changes was deferred which resulted in an $8 million regulatory liability at December 31, 2016.

(i)Deferrals for property taxes are limited to 90 percent of the difference from amounts reflected in rates, subject to an annual maximum for the remaining difference of not more than a 10 basis point impact on return on common equity.

(j)Calculated in accordance with the earnings calculation method prescribed in the rate order.

Pursuant to the CECONY 2023-2026 steam rate plan, CECONY may file petitions for approval of future decarbonization projects and may defer/capitalize up to $3 million in total incremental operation and maintenance and/or capital costs for preliminary work on future decarbonization projects until there is a NYSPSC order on cost recovery.

Rockland Electric Company (RECO)

In December 2021, the NJBPU approved an electric rate increase, effective January 1, 2022, of $9.65 million for RECO. The following table contains a summary of the terms of the distribution rate plans.

RECO
Effective period	January 2022
Base rate changes	$9.65 million
Amortization to income of net regulatory (assets) and liabilities	$0.2 million over three years and $9.2 million of deferred storm costs over a three-year period (excluding $2.4 million of costs for Tropical Storm Henri which will be deferred over a three year period in base rates) and continuation of $10 million over 3 years
Recoverable energy costs	Current rate recovery of purchased power costs.
Cost reconciliations	Reconciliation of uncollectible accounts, Demand Side Management and Clean Energy Program.
Average rate base	$262.8 million
Weighted average cost of capital (after-tax)	7.08 percent
Authorized return on common equity	9.6 percent
Actual return on common equity	Yr. 1 - 9.6 percent Yr. 2 - 9.7 percent Yr. 3 - 8.3 percent
Cost of long-term debt	4.74 percent
Common equity ratio	48.51 percent

Effective July 2021, the NJBPU authorized a conservation incentive program for RECO, that covers all residential and most commercial customers, under which RECO’s actual electric distribution revenues are compared with the authorized distribution revenues and the difference accrued, with interest, for refund to, or recovery from, customers, as applicable. The conservation incentive program is not permitted if RECO’s actual return on equity exceeds the approved base rate filing return on equity by 50 basis points or more.

In December 2022, the NJBPU authorized a $47.8 million Infrastructure Investment Program (IIP) over a five-year period (2023 – 2027). RECO’s IIP provides accelerated infrastructure investments to enhance safety, reliability, and resiliency.

In October 2023, FERC approved a July 2023 settlement agreement among RECO, the New Jersey Division of Rate Counsel and the NJBPU that resolves all issues set for hearing and increases RECO's annual transmission revenue requirement from $16.9 million to $18.2 million, effective August 30, 2022 through December 31, 2023 and to $20.7 million, effective January 1, 2024.

In November 2024, RECO filed a petition with the NJBPU for an order authorizing RECO to defer incremental preparation costs of $5 million associated with six storms that occurred during 2023 and 2024 until RECO’s next base rate case.

Bill Relief Program

In March 2024, CECONY and O&R received $91 million and $9 million, respectively, pursuant to a New York State bill relief program funded by the state that provided a one-time bill credit for electric and gas customers. The program was established to partially offset the costs all customers pay to fund utility energy affordability programs.

Other Regulatory Matters

In January 2023, CECONY initiated a review of welds on certain gas and steam mains following the company’s discovery of a leak from a gas main weld in Queens, New York. During the course of its review thus far, CECONY discovered a limited number of other non-conforming gas and steam main welds. New York regulations require utilities to perform and record weld films for certain gas and steam main welds. Upon reviewing these films, CECONY determined that in some instances third-party contractors engaged in misconduct by substituting duplicate weld films for different welds, while another third-party contractor had created poor quality weld films. CECONY voluntarily disclosed its initial review and findings to the NYSDPS which, in turn, initiated its own investigation. CECONY also reported the contractors’ misconduct to law enforcement. Given the nature of the non-conforming

welds identified, CECONY does not anticipate significant impact to the operation of its gas and steam mains. CECONY continues to investigate this matter, is remediating and monitoring the known non-conforming welds and is cooperating with the NYSDPS on its investigation of this matter. CECONY is unable to estimate the amount or range of its possible loss, if any, related to this matter. At December 31, 2024, CECONY had not accrued a liability related to this matter.

In May 2024, the NYSPSC issued an order denying an April 2023 petition by CECONY that requested permission to capitalize costs to implement its new customer billing and information system to the extent those costs exceeded the $421 million cap established in CECONY’s 2020 – 2022 electric and gas rate plans. CECONY’s final costs for the new system were $510 million ($89 million above the $421 million cap in the rate plans). CECONY believes that the incremental costs were both prudent and necessary for the successful deployment of the system for the benefit of its customers. In May 2024, CECONY expensed incremental costs of $51 million for the new system that were previously capitalized, in addition to a $38 million reserve established at December 31, 2023. In June 2024, CECONY filed a petition for rehearing with the NYSPSC. CECONY is unable to predict the NYSPSC's response to its rehearing petition.

In January 2018, the NYSPSC issued an order initiating a focused operations audit of the Utilities’ financial accounting for income taxes. The audit is investigating the Utilities’ inadvertent understatement of a portion, the amount of which may be material, of their calculation of total federal income tax expense for ratemaking purposes related to the calculation of plant retirement-related cost of removal. As a result of such understatement, the Utilities accumulated significant income tax regulatory assets ($1,078 million and $14 million for CECONY and O&R, respectively, as of December 31,2024 and $1,113 million and $18 million for CECONY and O&R, respectively, as of December 31, 2023) which are not earning a return. While the Utilities have properly calculated and paid their federal income taxes and there is no uncertain tax position related to this matter, this understatement of historical income tax expense materially reduced the amount of revenue collected from the Utilities' customers in the past relative to what it should have been. The Utilities’ rate plans have reflected the correct amount of federal income taxes recoverable from customers, including a proportionate recovery of the regulatory asset, beginning with O&R’s rate plans effective November 2015, CECONY’s electric and gas rate plans effective January 2017, and CECONY’s steam plan effective November 2023. As part of the audit, the Utilities plan to pursue a private letter ruling from the Internal Revenue Service (IRS) confirming that the Utilities’ inadvertent understatement of prior years’ income tax expense constitutes a normalization violation that can be cured through an increase in future years’ revenue requirements until such time as the regulatory asset is fully recovered in rates, and not through a write-down of all or a portion of the Utilities’ regulatory asset. Under Accounting Standards Codification Topic (ASC) 740, the Utilities recorded an unfunded deferred federal income tax liability (with a gross-up amount) and a corresponding regulatory asset. The income tax regulatory assets are netted against the related regulatory liability for future income tax and are shown in the line “Future income tax” in the following table of Regulatory Assets and Liabilities and on the Companies’ consolidated balance sheets in the line “Regulatory liabilities.” Management’s assessment is that the income tax regulatory assets as of December 31, 2024 are probable of collection through future rates. The IRS provides safe harbor relief for inadvertent normalization violations through the jurisdictional rate setting process of including in rates adequate revenue to fully recover the deferred tax balance. However, the Utilities would record a liability or impair a portion of the regulatory assets associated with this understatement if the NYSPSC were to issue an order that required the Utilities to write off all or a portion of their existing regulatory asset. The Utilities are unable to estimate the amount or range of their possible loss, if any, related to this matter. At December 31, 2024, the Utilities had not accrued a liability related to this matter.

(a) Energy Efficiency and Other Clean Energy Programs represent programs designed to increase energy efficiency achievements and other clean energy transformation efforts.

(b) Customer account deferrals include (1) the amount to be collected from customers related to the Emergency Summer Cooling Credits program for CECONY, (2) deferrals under CECONY and O&R's electric and gas rate plans for the reconciliation of write-offs of customer accounts receivable balances to amounts reflected in rates as well as for increases to the allowance for uncollectible accounts receivable and (3) deferral related to the arrears relief programs. Amounts deferred under the arrears relief programs were $323.7 million and $1.4 million for CECONY and O&R at December 31, 2024, respectively, and $398.6 million and $2.1 million at December 31, 2023, respectively, and receive a return at the pre-tax weighted average cost of capital.

(c) Pursuant to their rate plans, CECONY and O&R are recovering the costs of legacy meters over a 15-year period beginning January 1, 2024 and a 12-year period beginning January 1, 2022, respectively.

(d) Deferred storm costs represent response and restoration costs, other than capital expenditures, in connection with Tropical Storm Isaias and other major storms that were deferred by the Utilities.

(e) Property tax reconciliation represents the amount deferred between actual property taxes incurred and the level included in rates subject to the provisions of the respective rate plans.

(f) MTA power reliability deferral represents CECONY’s costs in excess of those reflected in its prior electric rate plan to take certain actions relating to the electrical equipment that serves the Metropolitan Transportation Authority (MTA) subway system. The company is recovering this regulatory asset pursuant to its current electric rate plan. See footnote (d) to the CECONY - Electric table under “Rate Plans,” above.

(g) Allowance for cost of removal less salvage represents cash previously collected from customers to fund future anticipated removal expenditures.

(h) Unrecognized pension and other postretirement costs represent the deferrals associated with the accounting rules for retirement benefits. See "Pension and Other Postretirement Benefits" in Note A.

(i) Settlement of prudence proceeding represents the remaining amount to be credited to customers pursuant to a Joint Proposal, approved by the NYSPSC in April 2016, with respect to the prudence of certain CECONY expenditures and related matters.

The NYSPSC has authorized CECONY to accrue unbilled electric, gas and steam revenues. CECONY has deferred the differences between unbilled revenues and energy costs for the future benefit of customers by recording a regulatory liability of $436 million and $278 million at December 31, 2024 and 2023, respectively.

In general, the Utilities receive or are being credited with a return at the Other Customer-Provided Capital rate for regulatory assets that have not been included in rate base, and receive or are being credited with a return at the pre-tax weighted average cost of capital once the asset is included in rate base. Similarly, the Utilities pay to or credit customers with a return at the Other Customer-Provided Capital rate for regulatory liabilities that have not been included in rate base, and pay to or credit customers with a return at the pre-tax weighted average cost of capital once the liability is included in rate base. The Other Customer-Provided Capital rate for the years ended December 31, 2024 and 2023 was 5.95 percent and 5.20 percent, respectively.

In general, the Utilities are receiving or being credited with a return on their regulatory assets for which a cash outflow has been made ($3,262 million and $2,541 million for Con Edison, and $3,024 million and $2,359 million for CECONY at December 31, 2024 and 2023, respectively). Regulatory assets of RECO for which a cash outflow has been made ($28 million and $24 million at December 31, 2024 and 2023, respectively) are not receiving or being credited with a return. RECO recovers regulatory assets over a period of up to four years or until they are addressed in its next base rate case in accordance with the rate provisions approved by the NJBPU. Regulatory liabilities are treated in a consistent manner.

Regulatory assets that represent future financial obligations and were deferred in accordance with the Utilities’ rate plans or orders issued by state regulators do not earn a return until such time as a cash outlay has been made. Regulatory liabilities are treated in a consistent manner. At December 31, 2024 and 2023, regulatory assets for Con Edison and CECONY that did not earn a return consisted of the following items:

Regulatory Assets Not Earning a Return*

	Con Edison		CECONY
(Millions of Dollars)	2024	2023	2024	2023
Environmental remediation costs	$1,037	$1,105	$942	$1,022
Revenue taxes	567	490	543	470
UB deferral for uncollectible accounts receivable	551	291	541	288
Deferred derivative losses - long term	106	163	94	148

Other	39	29	28	28
Total	$2,402	$2,347	$2,240	$2,209

*This table presents regulatory assets not earning a return for which no cash outlay has been made.

The recovery periods for regulatory assets for which a cash outflow has not been made and that do not earn a return have not yet been determined, except as noted below, and are expected to be determined pursuant to the Utilities’ future rate plans to be filed or orders issued by the state regulators in connection therewith.

The Utilities recover unrecognized pension and other postretirement costs over 10 years, and the portion of investment gains or losses recognized in expense over 15 years, pursuant to NYSPSC policy.

The deferral for revenue taxes represents the New York State metropolitan transportation business tax surcharge on the cumulative temporary differences between the book and tax basis of assets and liabilities of the Utilities, as well as the difference between taxes collected and paid by the Utilities to fund mass transportation. The Utilities recover the majority of the revenue taxes over the remaining book lives of the electric and gas plant assets, as well as the steam plant assets for CECONY.

The Utilities recover deferred derivative losses – current within one year, and noncurrent generally within three years.

Electricity and Gas Purchase Agreements

The Utilities have electricity purchase agreements with non-utility generators and others for generating capacity and gas purchase agreements for natural gas supply, transportation and storage. The Utilities recover their purchased power and gas costs in accordance with provisions approved by the applicable state public utility regulators. See “Recoverable Energy Costs” in Note A. The Utilities also conducted auctions and have entered into various other electricity and gas purchase agreements. Assuming performance by the parties to the electricity purchase agreements, the Utilities are obligated over the terms of the agreements to make capacity and other fixed payments.

The future capacity and other fixed payments under the electricity and gas purchase agreements are estimated to be as follows:

(Millions of Dollars)	2025	2026	2027	2028	2029	All Years Thereafter
Con Edison
Electricity power purchase agreements	$234	$131	$60	$49	$44	$302
Natural gas	383	11	8	—	—	—
Gas transportation and storage	510	497	450	376	212	2,390

Natural gas	331	10	7	—	—	—
Gas transportation and storage	445	434	394	329	185	2,083

For energy delivered and gas purchased under most of the electricity and gas purchase agreements, the Utilities are obligated to pay variable prices. The company’s payments under the significant terms of the agreements for capacity, energy, gas transportation and storage, and other fixed payments in 2024, 2023 and 2022 were as follows:
