CON EDISON REPORTS 2017 EARNINGS

NEW YORK - Consolidated Edison, Inc. (Con Edison) (NYSE: ED) today reported 2017 net income of $1,525 million or $4.97 a share compared with $1,245 million or $4.15 a share in 2016. Adjusted earnings were $1,264 million or $4.12 a share in 2017 compared with $1,198 million or $3.99 a share in 2016. Adjusted earnings for 2017 exclude the re-measurement of Con Edison's deferred tax assets and liabilities upon enactment of the Tax Cuts and Jobs Act of 2017 (TCJA), the effects of the gain on the sale of a solar electric production project and the net mark-to-market of Con Edison Clean Energy Businesses, Inc. (the Clean Energy Businesses or the CEBs). Adjusted earnings for 2016 exclude the effects of the gain on the sale of the CEBs' retail electric supply business, the goodwill impairment of the CEBs' energy service business and the net mark-to-market of the CEBs.

For the fourth quarter of 2017, net income was $505 million or $1.63 a share compared with $207 million or $0.68 a share in the fourth quarter of 2016. Adjusted earnings were $247 million or $0.80 a share in 2017 compared with $211 million or $0.69 a share in 2016. Adjusted earnings for the fourth quarter of 2017 exclude the re-measurement of Con Edison's deferred tax assets and liabilities upon enactment of the TCJA and the net mark-to-market effects of the Clean Energy Businesses. Adjusted earnings for the fourth quarter of 2016 exclude the effects of the gain on the sale of the CEBs' retail electric supply business, the goodwill impairment of the CEBs' energy service business and the net mark-to-market of the CEBs.

“The company’s performance was strong in 2017, and we continue to be committed to safety, reliability, and improving the customer experience,” said John McAvoy, Con Edison’s chairman and CEO. “We are working every day to lead the way to a new energy future that increasingly relies on clean, renewable resources. Our employees also took on both new and unexpected challenges, including performing heroically coming to the aid of hurricane victims in Florida and Puerto Rico."

The following table is a reconciliation of Con Edison’s reported earnings per share to adjusted earnings per share and reported net income to adjusted earnings for the three months and the years ended December 31, 2017 and 2016.

Adjusted earnings per share and adjusted earnings (non-GAAP basis)	$0.80	$0.69	$247	$211	$4.12	$3.99	$1,264	$1,198

(a) After taxes of $(48) million for the year ended December 31, 2016, which includes an adjustment for the apportionment of state income taxes.

(b) After taxes of $3 million for the three months and the year ended December 31, 2016.

(c) Upon enactment of the TCJA, Con Edison re-measured its deferred tax assets and liabilities based upon the 21 percent corporate income tax rate under the TCJA. As a result, Con Edison decreased its net deferred tax liabilities by $5,312 million, recognized $259 million (or $0.84 per share and $0.85 per share for the three months and the year ended December 31, 2017, respectively) in net income, decreased its regulatory asset for future income tax by $1,250 million, decreased its regulatory asset for revenue taxes by $90 million and accrued a regulatory liability for future income tax of $3,713 million. The amounts recognized in net income were $269 million (or $0.87 per share and $0.88 per share for the three months and the year ended December 31, 2017, respectively), $11 million (or $0.04 per share for the three months and the year ended

CON EDISON REPORTS 2017 EARNINGS page 2

December 31, 2017), and $(21) million (or $(0.07) per share for the three months and the year ended December 31, 2017) for the Clean Energy Businesses, Con Edison Transmission, Inc., and the parent company, respectively.

(d) After taxes of $(2) million for the year ended December 31, 2016.

The company expects its adjusted earnings for the year 2018 to be in the range of $4.15 to $4.35 per share. Adjusted earnings per share exclude the Clean Energy Businesses' net mark-to-market effects, the amount of which will not be determinable until year end. The forecast reflects capital investments of $3,969 million and operations and maintenance expenses of $3,095 million.

Con Edison plans to meet its 2018 capital requirements through internally-generated funds and the issuance of securities. The company's plans include the issuance of between $1,300 million and $1,800 million of long-term debt at the utilities, and the issuance of additional debt secured by its renewable electric production projects. The plans also include the issuance of up to $450 million of common equity in addition to equity under its dividend reinvestment, employee stock purchase and long term incentive plans. The plans do not reflect the provision to the utilities’ customers of any TCJA benefits that the New York State Public Service Commission and the New Jersey Board of Public Utilities may require to be provided.

The results of operations for the three months and the year ended December 31, 2017, as compared with the 2016 periods, reflect changes in rate plans and regulatory charges and the impact of weather on steam revenues. The results of operations also reflect income from renewable investments at the Clean Energy Businesses and income from equity investments at Con Edison Transmission, Inc. Operations and maintenance expenses for Consolidated Edison Company of New York, Inc. (CECONY) for the three months and the year ended December 31, 2017 primarily reflect lower costs for pensions and other postretirement benefits. In addition, the utilities' rate plans provide for revenues to cover expected changes in certain operating costs including depreciation, property taxes and other tax matters. See Attachments B and C to this press release for the estimated effect on earnings per share and net income for the 2017 periods compared to the 2016 periods resulting from these and other factors.

The Company's 2017 Annual Report on Form 10-K is being filed with the Securities and Exchange Commission. Consolidated income statements for 2017 and 2016 are attached to this press release (Attachment A). A 2017 earnings release presentation will be available at www.conedison.com (select "For Investors" and then select "Press Releases").

This press release contains forward-looking statements that are intended to qualify for the safe-harbor provisions of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements are statements of future expectations and not facts. Words such as “forecasts,” “expects,” “estimates,” “anticipates,” “intends,” “believes,” “plans,” “will” and similar expressions identify forward-looking statements. The forward-looking statements reflect information available and assumptions at the time the statements are made, and speak only as of that time. Actual results or developments may differ materially from those included in the forward-looking statements because of various factors such as those identified in reports the company has filed with the Securities and Exchange Commission, including that the company’s subsidiaries are extensively regulated and are subject to penalties; its utility subsidiaries’ rate plans may not provide a reasonable return; it may be adversely affected by changes to the utility subsidiaries’ rate plans; the intentional misconduct of employees or contractors could adversely affect it; the failure of, or damage to, its subsidiaries’ facilities could adversely affect it; a cyber-attack could adversely affect it; it is exposed to risks from the environmental consequences of its subsidiaries’ operations; a disruption in the wholesale energy markets or failure by an energy supplier could adversely affect it; it has substantial unfunded pension and other postretirement benefit liabilities; its ability to pay dividends or interest depends on dividends from its subsidiaries; it requires access to capital markets to satisfy funding requirements; changes to tax laws could adversely affect it; its strategies may not be effective to address changes in the external business environment; and it also faces other risks that are beyond its control.

This press release also contains a financial measure, adjusted earnings, that is not determined in accordance with generally accepted accounting principles in the United States of America (GAAP). This non-GAAP financial measure should not be considered as an alternative to net income, which is an indicator of financial performance determined in accordance with GAAP. Adjusted earnings excludes from net income the net mark-to-market changes in the fair value of the derivative instruments theClean Energy Businesses use to economically hedge market price fluctuations in related underlying physical transactions for the purchase or sale of electricity and gas. Adjusted earnings may also exclude from net income certain other items that the company does not consider indicative of its ongoing financial performance. Management uses this non-GAAP financial measure to facilitate the analysis of the company's financial performance as compared to its internal budgets and previous financial results. Management also uses this non-GAAP financial measure to communicate to investors and others the company’s expectations regarding its future earnings and dividends on its common stock. Management believes that this non-GAAP financial measure is also useful and meaningful to investors to facilitate their analysis of the company's financial performance.
