Electricity Purchase Agreements Regulatory Matters
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 NJBPU. The tariffs include schedules of rates for service that limit the rates charged by the Utilities to amounts that 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:
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.

Cost reconciliations that reconcile pension and other postretirement benefit costs, environmental remediation costs, property taxes, variable-rate tax-exempt debt and certain other costs 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.
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.
Positive revenue adjustments for achievement of performance standards related to achievement of clean energy goals, 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.
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”). 
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 pretax 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).

(a)In January 2020, the NYSPSC approved the October 2019 Joint Proposal for CECONY's electric rate plan for January 2020 through December 2022. If at the end of any semi-annual period ending June 30 and December 31, Con Edison’s investments in its non-utility businesses exceed 15 percent of its total consolidated revenues, assets or cash flow, or if the ratio of holding company debt to total consolidated debt rises above 20 percent, CECONY is required to notify the NYSPSC and submit a ring-fencing plan or a demonstration why additional ring-fencing measures (see Note T) are not necessary.
(b)The electric base rate increases were in addition to a $48 million increase resulting from the December 2016 expiration of a temporary credit under the prior rate plan. At the NYSPSC’s option, these increases were implemented with increases of $199 million in each rate year. Base rates reflect recovery by the company of certain costs of its energy efficiency, system peak reduction and electric vehicle programs (Yr. 1 - $20.5 million; Yr. 2 - $49 million; and Yr. 3 - $107.5 million) over a 10-year period, including the overall pre-tax rate of return on such costs.

(d)Amounts reflect amortization of the 2018 tax savings under the federal Tax Cuts and Jobs Act of 2017 (TCJA) allocable to CECONY’s electric customers ($377 million) over a three-year period ($126 million annually), the protected portion of the regulatory liability for excess deferred income taxes allocable to CECONY’s electric customers ($1,663 million) over the remaining lives of the related assets ($49 million in Yr. 1, $50 million in Yr. 2, and $53 million in Yr. 3) and the unprotected portion of the net regulatory liability ($784 million) over five years ($157 million annually). Amounts also reflect amortization of the regulatory asset for deferred MTA power reliability costs ($238 million) over a five-year period ($48 million annually).
(e)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.
(f)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
30 percent of the amount reflected in the January 2017-December 2019 rate plan and 15 percent of the amount reflected in the January 2020-December 2022 rate plan.
(g)In addition, the NYSPSC staff has commenced a focused operations audit to investigate the income tax accounting of CECONY and other New York utilities. Any NYSPSC-ordered adjustment to CECONY’s income tax accounting will be refunded to or collected from customers, as determined by the NYSPSC. See "Other Regulatory Matters," below.

The revenue requirement reflects a return on common equity of 10.0 percent.

COVID-19 Regulatory Matters
Governors, public utility commissions and other regulatory agencies in the states in which the Utilities operate have issued orders related to the COVID-19 pandemic that impact the Utilities as described below.

New York State Regulation
In March 2020, New York State Governor Cuomo declared a State Disaster Emergency for the State of New York due to the COVID-19 pandemic and signed the "New York State on PAUSE" executive order that closed all non-essential businesses statewide. New York State designated utilities, including CECONY and O&R, as essential businesses that were able to continue a portion of their work during the effectiveness of the PAUSE order. In May 2020, the "New York Forward" plan went into effect. New York Forward is a phased plan to reopen businesses in geographic areas of New York State that meet metrics established by various public health organizations. In October 2020, Governor Cuomo announced a new cluster action initiative to address COVID-19 hotspots that have arisen in various areas of New York within the Utilities’ service territory and to impose new rules and restrictions targeted to areas with the highest concentration of COVID-19 cases and the surrounding communities. As a result of these COVID-19 clusters, the Utilities have limited their work in customer premises in the impacted areas to only address emergency, safety-related and selected service connections requested by customers. Since the emergency declaration, and due to economic conditions, the NYSPSC and the Utilities have worked to mitigate the potential impact of the COVID-19 pandemic on the Utilities, their customers and other stakeholders.

In March 2020, the Utilities began suspending service disconnections, certain collection notices, final bill collection agency activity, new late payment charges and certain other fees for all customers. The Utilities also began providing payment extensions for all customers that were scheduled to be disconnected prior to the start of the COVID-19 pandemic. In June 2020, the state of New York enacted a law prohibiting New York utilities, including CECONY and O&R, from disconnecting residential customers during the COVID-19 state of emergency. In addition, such prohibition will apply for an additional 180 days after the state of emergency ends for residential customers who have experienced a change in financial circumstances due to the COVID-19 pandemic. The law expires on March 31, 2021, although legislation has been introduced to extend the expiration date until December 31, 2021 or later. For the year ended December 31, 2020, the estimated foregone revenues that were not collected by CECONY and O&R were approximately $61 million and $3 million, respectively (see Note M). Also in March 2020, the Utilities requested and the NYSPSC granted extensions to file their 2019 Earnings Adjustment Mechanisms (EAMs) reports, which were filed in July 2020. The earned EAM incentives of approximately $46 million and $3 million for CECONY
and O&R, respectively, are being recovered from customers over a twelve-month period that began September 2020.

In June 2020, the NYSPSC directed CECONY to implement a summer cooling credit program to help mitigate the cost of staying home and operating air conditioning for health-vulnerable low-income customers due to the limited availability of public cooling facilities as a result of the COVID-19 social distancing measures. The cost of the program is being recovered over a five-year period that began January 2021. As of December 31, 2020, CECONY deferred for later recovery $63.4 million of summer cooling credit costs.

The Utilities’ New York rate plans allow them to defer costs resulting from a change in legislation, regulation and related actions that have taken effect during the term of the rate plans once the costs exceed a specified threshold. For the year ended December 31, 2020, the reserve increases to the allowance for uncollectible accounts associated with the COVID-19 pandemic for CECONY electric and gas operations and O&R electric operations were $73 million and $2 million, respectively, and were deferred pursuant to the legislative, regulatory and related actions provisions of the rate plans as a result of the New York State on PAUSE and related executive orders. The reserve increase to the allowance for uncollectible accounts associated with the COVID-19 pandemic for O&R gas operations of $1 million did not meet the deferral threshold at December 31, 2020. The Utilities’ New York rate plans also provide for an allowance for write-offs of customer accounts receivable balances. The above amounts deferred pursuant to the legislative, regulatory and related actions provisions were reduced by the amount that the actual write-offs of customer accounts receivable balances were below the allowance reflected in rates (due to the New York State on PAUSE and related executive orders), which differences were $18 million and $1 million for CECONY and O&R, respectively, for the year ended December 31, 2020.

In June 2020, the NYSPSC established a generic proceeding on the impacts of the COVID-19 pandemic and sought comment on a variety of COVID-19 related issues. In July 2020, the Utilities submitted joint comments with other large utilities in New York State that included a formal request to defer all COVID-19 related costs and for a surcharge mechanism to collect such deferrals based upon the individual utility's need. In January 2021, NYSPSC staff provided guidance to New York utilities that no additional mechanisms are required because there are already established mechanisms for utility recovery of unexpected material expenses through rate plan change in legislation, regulation and related actions provisions and the filing of individual deferral petitions The guidance further provided that utilities deferring COVID-19 related costs pursuant to the provisions that allow deferral of costs resulting from a change in legislation, regulation and related actions must comply with the provisions of their rate plans, be able to demonstrate the nexus between the changes in law or regulation and the specific revenue and expense items, and consider any offsetting cost savings due to the pandemic.

In February 2021, the NYSPSC staff issued its report on New York State’s Energy Affordability Policy that provides recommendations to large New York utilities, including CECONY and O&R. The report recommends, among other things, that residential and commercial customers’ late payment fees and interest on deferred payment agreements be waived until two years after the expiration of the New York State moratorium on utility terminations (the moratorium currently expires on March 31, 2021, although legislation has been introduced to extend the expiration to December 31, 2021 or later) and each utility develop an arrears management program to mitigate the financial burdens of the COVID-19 pandemic on New York households and that program costs be shared, perhaps equally, between shareholders and customers. The NYSPSC staff has requested that the utilities and interested parties comment on the report prior to staff submitting the recommendations to the NYSPSC for consideration.

As of December 31, 2020, CECONY deferred, for New York City residential customers, $54.9 million of higher summer generation capacity supply costs. CECONY expects to recover such costs from customers by October 2021.

The Utilities’ rate plans have revenue decoupling mechanisms in their New York electric and gas businesses that reconcile actual energy delivery revenues to the authorized delivery revenues approved by the NYSPSC per month and accumulate the deferred balances semi-annually under CECONY's electric rate plan (January through June and July through December, respectively) and annually under CECONY's gas rate plan and O&R New York's electric and gas rate plans (January through December). Differences are accrued with interest each month for CECONY and O&R New York’s electric customers and after the annual deferral period ends for CECONY and O&R New York’s gas customers for refund to, or recovery from customers, as applicable. Generally, the refund to or recovery from customers begins August and February of each year over an ensuing six-month period for CECONY's electric customers and February of each year over an ensuing twelve-month period for CECONY's gas and O&R New York's electric and gas customers.
New Jersey State Regulation
In March 2020, New Jersey Governor Murphy declared a Public Health Emergency and State of Emergency for the State of New Jersey. Since that declaration, the NJBPU and RECO have worked to mitigate the potential impact of the COVID-19 pandemic on RECO, its customers and other stakeholders. In March 2020, RECO began suspending late payment charges, terminations for non-payment, and no access fees during the COVID-19 pandemic. The suspension of these fees is not expected to be material.

In July 2020, the NJBPU authorized RECO and other New Jersey utilities to create a COVID-19-related regulatory asset by deferring prudently incurred incremental costs related to the COVID-19 pandemic beginning on March 9, 2020, and through the later of September 30, 2021, or 60 days after the emergency declaration is no longer in effect. RECO deferred net incremental COVID-19 related costs of $0.5 million through December 31, 2020.

Other Regulatory Matters
In August 2018, the NYSPSC ordered CECONY to begin on January 1, 2019 to credit the company's electric and gas customers, and to begin on October 1, 2018 to credit its steam customers, with the net benefits of the federal Tax Cuts and Jobs Act of 2017 (TCJA) as measured based on amounts reflected in its rate plans prior to the enactment of the TCJA in December 2017. The net benefits include the revenue requirement impact of the reduction in the corporate federal income tax rate to 21 percent, the elimination for utilities of bonus depreciation and the amortization of excess deferred federal income taxes.

CECONY, under its electric rate plan that was approved in January 2020, is amortizing its TCJA net benefits prior to January 1, 2019 allocable to its electric customers ($377 million) over a three-year period, the “protected” portion of its net regulatory liability for future income taxes related to certain accelerated tax depreciation benefits allocable to its electric customers ($1,663 million) over the remaining lives of the related assets and the remainder, or “unprotected” portion of the net regulatory liability allocable to its electric customers ($784 million) over a five-year period. CECONY, under its gas rate plan that was approved in January 2020, is amortizing its remaining TCJA net benefits prior to January 1, 2019 allocable to its gas customers ($63 million) over a two-year period, the protected portion of its net regulatory liability for future income taxes allocable to its gas customers ($725 million) over the remaining lives of the related assets and the unprotected portion of the net regulatory liability allocable to its gas customers ($107 million) over a five-year period. See footnote (d) to the CECONY - Electric and Gas tables under “Rate Plans,” above.

CECONY's net benefits prior to October 1, 2018 allocable to the company’s steam customers ($15 million) are being amortized over a three-year period. CECONY’s net regulatory liability for future income taxes, including both the protected and unprotected portions, allocable to the company’s steam customers ($185 million) is being amortized over the remaining lives of the related assets (with the amortization period for the unprotected portion subject to review in its next steam rate proceeding).

O&R, under its current electric and gas rate plans, has reflected its TCJA net benefits in its electric and gas rates beginning as of January 1, 2019. Under the rate plans, O&R is amortizing its net benefits prior to January 1, 2019 ($22 million) over a three-year period, the protected portion of its net regulatory liability for future income taxes ($123 million) over the remaining lives of the related assets and the unprotected portion ($30 million) over a fifteen-year period. See "Rate Plans," above.

In January 2018, the NYSPSC issued an order initiating a focused operations audit of the income tax accounting of certain utilities, including CECONY and O&R. The Utilities are unable to estimate the amount or range of their possible loss related to this matter. At December 31, 2020, the Utilities had not accrued a liability related to this matter.

In March 2018, Winter Storms Riley and Quinn caused damage to the Utilities’ electric distribution systems and interrupted service to approximately 209,000 CECONY customers, 93,000 O&R customers and 44,000 RECO customers. At December 31, 2020, CECONY's costs related to March 2018 storms, including Riley and Quinn, amounted to $134 million, including operation and maintenance expenses reflected in its electric rate plan ($15 million), operation and maintenance expenses charged against a storm reserve pursuant to its electric rate plan ($84 million), capital expenditures ($29 million) and removal costs ($6 million). At December 31, 2020, O&R and RECO costs related to 2018 storms amounted to $43 million and $17 million, respectively, most of which were deferred as regulatory assets pursuant to their electric rate plans. In January 2019, O&R began recovering its deferred storm costs over a six-year period in accordance with its New York electric rate plan. In February 2020, RECO began recovering its deferred storm costs over a four-year period in accordance with its New Jersey electric
rate plan. The NYSPSC investigated the preparation and response to the storms by CECONY, O&R, and other New York electric utilities, including all aspects of their emergency response plans. In April 2019, following the issuance of a NYSPSC staff report on the investigation, the NYSPSC ordered the utilities to show cause why the NYSPSC should not commence a penalty action against them for violating their emergency response plans. During 2020, CECONY and O&R accrued $5.6 million and $0.85 million, respectively, related to this matter. In August 2020, the NYSPSC approved a July 2020 settlement agreement that provides for the Utilities to set aside $5.6 million and $0.85 million for the benefit of CECONY and O&R electric customers, respectively.

In July 2018, the NYSPSC commenced an investigation into the rupture of a CECONY steam main located on Fifth Avenue and 21st Street in Manhattan. Debris from the incident included dirt and mud containing asbestos. The response to the incident required the closing of buildings and streets for various periods. The NYSPSC has commenced an investigation. As of December 31, 2019, with respect to the incident, the company incurred operating costs of $17 million for property damage, clean-up and other response costs and invested $9 million in capital and retirement costs. During the second quarter of 2020, the company accrued a $3 million liability related to this matter.

In March 2019, the NYSPSC ordered CECONY to show cause why the NYSPSC should not commence a penalty action and prudence proceeding against CECONY for alleged violations of gas operator qualification, performance, and inspection requirements. At December 31, 2019, the company had an accrued regulatory liability related to this matter of $10 million, and at March 31, 2020, the company accrued an additional regulatory liability of $5 million. In April 2020, the NYSPSC approved a $15 million settlement agreement for the benefit of CECONY’s gas customers between CECONY and NYSPSC staff related to this matter.

In July 2019, electric service was interrupted to approximately 72,000 CECONY customers on the west side of Manhattan. Also in July 2019, electric service was interrupted to approximately 30,000 CECONY customers primarily in the Flatbush area of Brooklyn. In November 2020, the NYSPSC issued an order in its proceedings investigating these July 2019 power outages ordering CECONY to show cause why the NYSPSC should not commence a review of the prudency of CECONY’s actions and/or omissions prior to, during, and after the July 2019 outages in Manhattan and Brooklyn, and pursue civil or administrative penalties in the amount of up to $24.8 million for CECONY’s alleged failure to comply with certain requirements. The order further indicated that should the NYSPSC confirm some or all of the apparent violations identified in the order or other orders issued by the NYSPSC in the future in connection with this proceeding, and should such confirmed violations be classified as findings of repeated violations of the Public Service Law or rules or regulations adopted pursuant thereto that demonstrate a failure of CECONY to continue to provide safe and adequate service, the NYSPSC would be authorized to commence a proceeding under Public Service Law Section 68(2) to revoke or modify CECONY’s certificate as it relates to its service territory or any portion thereof.

In December 2020, CECONY filed a response to the NYSPSC order demonstrating why the NYSPSC should not commence a penalty or prudence action against CECONY. CECONY stated that the NYSPSC order misapplied Section 25-a of the Public Service Law by ignoring the reasonable compliance standard under the statute and instead, was imposing a strict liability standard. For both outages, CECONY presented evidence that it either had complied or reasonably complied with NYSPSC requirements. With respect to the Manhattan outage, CECONY stated that a prudency proceeding was not justified because CECONY’s actions with respect to the Manhattan outage were reasonable based on the information the company had at the time. With respect to the Brooklyn outage, the company stated that the order failed to allege that improper company actions caused the outage. During 2019, CECONY recorded negative revenue adjustments associated with reliability performance provisions of $15 million in aggregate primarily related to these outages. CECONY has not accrued any additional liability related to this matter and is unable to determine the outcome of this proceeding at this time.

In August 2020, Tropical Storm Isaias caused significant damage to the Utilities’ electric distribution systems and interrupted service to approximately 330,000 CECONY electric customers and approximately 200,000 O&R electric customers. As of December 31, 2020, CECONY incurred costs for Tropical Storm Isaias of $153 million (including $77 million of operation and maintenance expenses charged against a storm reserve pursuant to its electric rate plan, $58 million of capital expenditures and $18 million of operation and maintenance expenses). As of December 31, 2020, O&R incurred costs for Tropical Storm Isaias of $34 million (including $26 million of operation and maintenance expenses charged against a storm reserve pursuant to its New York electric rate plan and $8 million of capital expenditures). The Utilities’ electric rate plans provide for recovery of operating costs and capital expenditures under different provisions. The Utilities’ incremental operating costs attributable to storms are to be deferred for recovery as a regulatory asset under their electric rate plans, while capital expenditures, up to specified levels, are reflected in rates under their electric rate plans. In addition, as of December 31, 2020, CECONY and O&R incurred costs of $7.5 million and $2.9 million, respectively, for food and medicine spoilage claims. The provisions of the Utilities’ New York electric rate plans that impose negative revenue adjustments for operating
performance provide for exceptions for major storms and catastrophic events beyond the control of the companies, including natural disasters such as hurricanes and floods.

In November 2020, the NYSPSC issued an order in its proceedings investigating the New York utilities’ preparation for and response to Tropical Storm Isaias that ordered the Utilities to show cause why (i) civil penalties or appropriate injunctive relief should not be imposed against CECONY (in the amount of up to $102.3 million relating to 33 alleged violations) and against O&R (in the amount of up to $19 million relating to 38 alleged violations) to remedy such noncompliance, and (ii) a prudence proceeding should not be commenced against the Utilities for potentially imprudent expenditures of ratepayer funds related to the matter. The order stated that given the continuing nature of the investigation of this matter by the New York State Department of Public Service (NYSDPS), the NYSPSC may amend the order to include any subsequently determined apparent violations identified by the NYSDPS. In addition, the order indicated that should the NYSPSC confirm some or all of the apparent violations identified in the order or other orders issued by the NYSPSC in the future in connection with this proceeding, and should such respective confirmed violations be classified as findings of repeated violations of the Public Service Law or rules or regulations adopted pursuant thereto that demonstrate a failure of CECONY and/or O&R to continue to provide safe and adequate service, the NYSPSC would be authorized to commence a proceeding under Public Service Law Section 68(2) to revoke or modify CECONY’s and/or O&R’s certificate as it relates to its service territory or any portion thereof.

In December 2020, CECONY and O&R filed responses to the NYSPSC order demonstrating why the NYSPSC should not commence penalty or prudence actions against them. The Utilities stated that the NYSPSC orders misapplied Section 25-a of the Public Service Law by ignoring the reasonable compliance standard under the statute and instead, was imposing a strict liability standard. CECONY and O&R also presented evidence that the order either misrepresented the applicable requirements or ignored that the Utilities were acting pursuant to practices approved by the NYSPSC. Finally, CECONY and O&R stated that there was no basis to commence a prudence proceeding because the Utilities acted reasonably based on the information available and the circumstances at the time. The Utilities have not accrued a liability related to this matter and are unable to determine the outcome of this proceeding at this time.

In October 2020, the NYSPSC issued an order instituting a proceeding to consider requiring New York’s large, investor-owned utilities, including CECONY and O&R, to annually disclose what risks climate change poses to their companies, investors and customers going forward. The order notes that some holding companies, including Con Edison, already disclose climate change risks at the holding company level, but states that the NYSPSC believes that climate-related risk disclosures should be issued specific to the operating companies in New York, such as CECONY and O&R, and that such climate-related risk disclosures should be included annually with the utilities’ financial reports. In December 2020, CECONY and O&R, along with other large New York utilities, filed comments supporting climate change risk disclosures in annual reports filed with the NYSPSC and recommended the use of an industry-specific template.

In May 2020, the president of the United States issued the "Securing the United States Bulk-Power System" executive order. The executive order declares threats to the bulk-power system by foreign adversaries constitute a national emergency and prohibits the acquisition, importation, transfer or installation of certain bulk-power system electric equipment that is sourced from foreign adversaries. The Department of Energy is expected to issue regulations implementing the executive order. In January 2021, the president of the United States suspended the May 2020 executive order for 90 days. The Companies are unable to predict the impact on them of regulations that may be adopted regarding the bulk-power system.

* See "Federal Income Tax" in Note A, "Other Regulatory Matters," above, and Note L.

Unrecognized pension and other postretirement costs represent the net regulatory asset associated with the accounting rules for retirement benefits. See Note A.
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.
Deferred storm costs represent response and restoration costs, other than capital expenditures, in connection with Tropical Storm Isaias, Superstorm Sandy and other major storms that were deferred by the Utilities.

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.

Settlement of gas proceedings represents the amount to be credited to customers pursuant to a settlement agreement approved by the NYSPSC in February 2017 related to CECONY’s practices of qualifying persons to perform plastic fusions on gas facilities and alleged violations of gas safety violations identified by the NYSPSC staff in its investigation of a March 2014 Manhattan explosion and fire (see Note H).

COVID - 19 Deferrals represents both the amount to be collected from customers related to the Emergency Summer Cooling Credits program for CECONY and amounts related to the increase in the allowance for uncollectible accounts resulting from the COVID-19 pandemic and New York on PAUSE and related executive orders, for electric and gas operations for CECONY and electric operations for O&R.
The NYSPSC has authorized CECONY to accrue unbilled electric, gas and steam revenues. CECONY has deferred the net margin on the unbilled revenues for the future benefit of customers by recording a regulatory liability of $198 million and $199 million at December 31, 2020 and 2019, respectively, for the difference between the unbilled revenues and energy cost liabilities.
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.
In general, the Utilities are receiving or being credited with a return on their regulatory assets for which a cash outflow has been made ($1,696 million and $1,188 million for Con Edison, and $1,509 and $1,054 million for CECONY at December 31, 2020 and 2019, respectively). Regulatory liabilities are treated in a consistent manner. The Other Customer-Provided Capital rate for the years ended December 31, 2020 and 2019 was 2.65 percent and 4.2 percent, respectively. The recognition of the return on regulatory assets is determined by the Utilities’ rate plans or orders issued by state regulators.
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, 2020 and 2019, regulatory assets for Con Edison and CECONY that did not earn a return consisted of the following items:
Regulatory Assets Not Earning a Return

Total4,7663,7994,4813,546
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 pursuant to NYSPSC policy.

The deferral for revenue taxes represent the 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 Purchase Agreements
The Utilities have electricity purchase agreements with non-utility generators and others for generating capacity. The Utilities recover their purchased power 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 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 purchase agreements are estimated to be as follows:
