Customer Affordability Remains a Top Priority CECONY electric customer bills are lower than our proxy peer average on both a total bill and share of wallet basis. 10 Information derived from data published by the U.S. Energy Information Administration (as of October 2026), St. Louis FRED, and CECONY’s internal analysis. Three year (2023 – 2025) average customer electric bills are annualized full-service residential bills. Share of wallet calculated as annual bill over median income. The “peers” are Con Edison’s proxy peers set forth in its proxy statement filed in April 2026, excluding CenterPoint Energy because directly comparable data was not available, and including O&R.

CECONY Electric Bills Over Time Compared to Peers CECONY has generally improved affordability over time, with the majority of CECONY customers receiving bills below peer average. Source: Energy Information Administration Note: CECONY’s and the peers’ numbers are the three-year (2023-2025) rolling average monthly bill for residential customers, with available EIA data. The “peers” are Con Edison’s proxy peers set forth in its proxy statement filed in April 2026, excluding CenterPoint Energy because directly comparable data was not available, and including O&R. 11 Ranking average electric bills by utility ($/month, 3-yr average) CECONY vs. Peer Average: • $180 less annually (12% lower) CECONY vs. Peer Median: • $216 less annually (14% lower)

Affordability Programs Are Easing the Energy Burden In 2025, we provided $268 million in bill discounts through affordability programs, supporting more than 500,000 income-eligible customers across New York and New Jersey.(a) 12 • ~494,000 customers enrolled: Approximately 14% of residential customers across CECONY and O&R service territories are enrolled in New York’s Energy Affordability Program (EAP) and Enhanced EAP (EEAP), as of August 2026. • Expanded eligibility: Through Enhanced EAP, households with incomes below the median income may be eligible for monthly bill discounts. To date, more than 25,000 customers(b) have been approved since the program’s January 2026 launch. • Supports affordability: Goal is to help eligible customers maintain an energy burden of approximately 6% of household income, and discounts increase as customer bills rise.(c) (a) Monthly bill discount programs include those for CECONY, O&R and RECO Matter Master: 14-02621/14-M-0565 (b) As of August 2026 (c) Discounts levels also account for changes in income indicators like federal, state, and area median income. Discounts may be limited by program budget.

Committed to Helping Customers Manage Energy Bills 13 Financial Assistance Programs for Vulnerable Customers • Monthly bill discounts reduce monthly energy costs for low- and moderate-income customers – Energy Affordability Program (EAP) aims to manage typical customer’s energy bills to 6% of wallet in NY.

NYSPSC & NYISO Proceedings and Developments 23 Utility Ownership of Renewables • On April 24, 2026, CECONY and O&R, along with other New York Utilities, submitted comments in response to questions posed by the NYSPSC related to Utility-owned Renewable Generation, proposing a separate procurement process in which utilities would jointly solicit bids for renewable projects. New York State Department of Public Service (NYSDPS) Staff is expected to issue a white paper, which would be subject to stakeholder comment, and followed by an NYSPSC order. (NYSPSC docket number 15-E-0302) • In October 2026, the NYISO reported that it had determined that the Champlain Hudson Power Express transmission project (CHPE) had demonstrated its planned power capability, and therefore, the Q3 2026 Short-Term Assessment of Reliability no longer identified a near-term reliability need. The NYISO noted, however, that its update did not affect the longer-term reliability assessments, and that it continued to foresee reliability concerns for the Lower Hudson Valley and New York City beginning in 2032, even assuming CHPE and other planned projects are available. • In July 2026, CECONY filed with the NYSPSC its updated Reliability Needs Report, which projects electric reliability needs in New York City of 125 MW beginning in 2033 and increasing to 675 MW by 2036. This report reflects a deferral of the need by one year and a reduction in the size of the need relative to the company’s January 2026 Reliability Needs Report. CECONY continues to project increasing long-term capacity shortfalls in its New York City transmission system, driven by load growth and generation retirements without new replacement generation materializing. (NYSPSC docket number 25-E-0764) • Also in July 2026, CECONY filed a reliability contingency plan with the NYSPSC to address transmission reliability needs in New York City. The plan emphasizes competitive procurement of clean energy resources, including transmission- and distribution-connected battery storage, while preserving flexibility to implement transmission infrastructure solutions, if necessary. CECONY requested regulatory approvals to support the competitive procurement of battery storage, including cost recovery. CECONY expects its proposed solutions, if approved, would be sufficient to address the identified ten-year reliability need through 2036 and will continue to evaluate evolving reliability forecasts, market conditions, technological developments and policy changes and provide updates to the NYSPSC. Electric Reliability Needs

NYSPSC & NYISO Proceedings and Developments (continued) 24 Clean Energy Zones • In May 2026, NYSDPS Staff issued a White Paper outlining two proposals to implement Clean Energy Zones (“CEZs”), areas where proactive coordination among New York State, developers, utilities, and communities could facilitate the co-deployment of new generation and transmission projects. The White Paper discusses two potential CEZ frameworks and a range of related policy and regulatory changes to support development in these areas. The NYSDPS Staff seeks stakeholder input on key design questions, including zone designation criteria and a number of items related to community engagement and benefits. The initiative aims to improve planning coordination, reduce costs, improve project development timelines and support the integration of more than 60 GW of renewable resources. Comments were originally due August 10, 2026 but have been extended to December 8, 2026. State Utility Regulation • In May 2026, as part of New York State’s Fiscal Year 2026-2027 Enacted Budget, the state enacted Chapter 58 of the Laws of 2026, which, among other things, amends and adds provisions to the Public Service Law governing utility rate cases and addressing affordability. Effective for base rate filings submitted by the Utilities after January 1, 2027, Chapter 58: (i) requires the Utilities to submit, in addition to their recommended proposal, a budget-constrained rate plan that limits aggregate revenue increases to the average Consumer Price Index growth over the prior three years; (ii) directs the Utilities to return revenues above the authorized return on equity (ROE), with retention of up to 0.25% over the authorized ROE if certain criteria are met; (iii) further defines non-recoverable lobbying expenses and formalizes non-recoverability of public relations and goodwill advertising expenses; (iv) extends the NYSPSC’s authority to suspend a rate case to 14 months; and (v) authorizes
