ITEM 1.01 Entry into a Material Definitive Agreement

On October 27, 2011, Consolidated Edison, Inc. (“Con Edison”) and its subsidiaries Consolidated Edison Company of New York, Inc. (“Con Edison of New York”) and Orange and Rockland Utilities, Inc. (“O&R,” and along with Con Edison and Con Edison of New York, each a “Company” and collectively, the “Companies”) entered into a Credit Agreement, dated as of October 27, 2011, (the “Credit Agreement”) among the Companies, the lenders party thereto (the “Lenders”) and JPMorgan Chase Bank, N.A., as Administrative Agent. A copy of the Credit Agreement is included as an exhibit to this report, and the description of the Credit Agreement that follows is qualified in its entirety by reference to the Credit Agreement.

The Credit Agreement terminates the Amended and Restated Credit Agreement, dated as of June 22, 2006, among the Companies, the banks party thereto and JPMorgan Chase Bank, N.A., as Administrative Agent.

Under the Credit Agreement, the Lenders committed to provide loans and letters of credit, on a revolving credit basis, in an aggregate amount of up to $2.25 billion of credit available, with the full amount available to Con Edison of New York, $1 billion available to Con Edison and $200 million available to O&R (subject to increase to $250 million if the necessary regulatory approvals are requested and obtained), including up to $1.2 billion of letters of credit. Subject to certain conditions, the Companies and one or more Lenders or additional lenders may increase by up to $500 million the aggregate principal amount of loans available under the Credit Agreement, with availability to each of the Companies proportionate to availability prior to the increase. Each Company will be severally obligated with respect to loans made to it, and letters of credit issued on its behalf, under the Credit Agreement. None of the Companies is responsible for the obligations under the Credit Agreement of any Company other than itself.

The Companies intend to use the Credit Agreement to support their commercial paper programs. Loans and letters of credit issued under the Credit Agreement may also be used for other general corporate purposes. Any borrowings under the Credit Agreement would generally be at variable interest rates. Interest and fees for loans and letters of credit under the Credit Agreement generally reflect the respective credit ratings of the Companies.

The Lenders’ commitments under the Credit Agreement to make a loan to, or issue a letter of credit on behalf of, a Company terminate on October 27, 2016, unless extended for additional one–year terms as provided therein, and are subject to certain conditions, including that there be no Event of Default (see below) or event which with notice or the lapse of time would become an event of default with respect to that Company, that the representations and warranties of the Company contained in the Credit Agreement (not including that the Company did not have a material adverse change) be true on and as of the date of such loan or issuance and, in the case of Con Edison of New York and O&R, that the Company shall have received required regulatory approvals.

Upon a change of control with respect to a Company, each Lender may terminate its commitments to that Company under the Credit Agreement, declare the loans, accrued interest and any other amounts owed by that Company under the Credit Agreement immediately due and payable and require that Company to provide cash collateral relating to the letters of credit issued for it under the Credit Agreement, in the manner, with such effect and subject to the conditions provided in the Credit Agreement.

If an event of default under the Credit Agreement (an “Event of Default”) with respect to a Company occurs and is continuing, the Lenders may terminate their commitments to that Company under the Credit Agreement, declare the loans (including accrued interest) under the Credit Agreement to that Company immediately due and payable and require that Company to provide cash collateral relating to the letters of credit issued for it under the Credit Agreement, in the manner, with such effect and subject to the conditions provided in the Credit Agreement. Events of Default, among others, include:
