Filed by Consolidated Edison, Inc. Pursuant to Rule 425 under the Securities Act of 1933 Subject Company: Consolidated Edison, Inc. (DE) Commission File No. 333-31390 The following information will be mailed on March 24, 2000 to all employees of Northeast Utilities: March 24, 2000 Dear Fellow Employee, As you know, on October 13, 1999, NU and Consolidated Edison, Inc. of New York (Con Edison) announced a merger that valued NU at more than three times the level at which our shares traded three years ago. I'd like to share my thoughts on this event with you. Of all the questions about the merger I hear, employees most often ask: "Is this a good deal?" and "Is this merger the right thing to do?" You know my feelings on the importance and value of our merger with Con Edison, but let me add some additional perspective. First, the original deal was designed to provide a per share value to NU shareholders of approximately $25 per share, assuming a Con Edison share price of at least $36 at closing. Today, the price of Con Edison shares is lower, and at its current share price, NU shareholders would receive a somewhat smaller return at closing. Bottom Line: NU's current share price is being supported by the announced merger. We believe that even if you allow some value for our investment in NEON, absent the merger, our share price would be quite a bit lower than it is today. In the competitive arena, size matters, and the enterprise value of the combined company will provide the financial resources that we anticipate will be needed to grow and prosper in the future. This strength and stability should help increase the efficiency of our operations, enhance our ability to deploy advanced technologies, further strengthen our infrastructure and customer service, and increase shareholder value through growth in earnings. In short, we believe this combination presents greater prospects for a bright future for employees, shareholders and customers. As you know, all the details about our forthcoming merger are contained in the Joint Proxy Statement which is also available online at www.nu.com/investor/proxy.pdf. Please read it carefully and be sure to call our Shareholder Services Department toll free at 1-800-794-1104 if you have any questions. - more - Your vote on these proposals is very important, and I urge you to please complete, sign, date and return each proxy card you receive right away.
