Remains Committed to Providing the Highest Quality Products and
             Services Throughout the Chapter 11 Process

               Obtains $2 Million Financing Commitment

WALLINGFORD, Conn., June 4, 2008 (PRIME NEWSWIRE) -- Distributed Energy Systems Corp. (Nasdaq:DESC) announced today that the corporation and its wholly-owned subsidiary, Northern Power Systems, Inc., have filed voluntary petitions under Chapter 11 of the United States Bankruptcy Code. The company determined today's voluntary filings were necessary to complete going-concern sales of the Northern Power unit and another wholly-owned subsidiary, Proton Energy Systems, Inc., and was the best course of action to maximize the value of the company's assets for all stakeholders including its 175 employees.

The company expects its operations to function normally during the Chapter 11 process, with little or no impact on how it conducts business. The company will continue to fulfill customer demands and provide uninterrupted customer service by honoring commitments in the normal course of business. The company will continue paying suppliers for goods and services they provide after the filings, and will pay all wages and benefits for active employees, as usual and without interruption.

To fund its continuing operations during the Chapter 11 process, the company obtained a $2 million debtor-in-possession (DIP) financing commitment from its senior secured lender, Perseus Partners VII, L.P. Subject to bankruptcy court approval, the DIP financing will be used to supplement the company's cash flow during the Chapter 11 process and is expected to provide adequate funds for the company to operate in the ordinary course of business.

Bernard Cherry, chief executive officer of Distributed Energy Systems Corp., said: "We are grateful for the continuing loyalty and support of our employees and customers. We intend to use the Chapter 11 process as a strategic vehicle to obtain the time and legal protection necessary to complete a structured sale of our two primary operating units, and to maintain the going concern value of both business units. Our dedication to providing our customers with the highest quality products and services will remain strong during this strategic process."

The Chapter 11 filings were made earlier today, June 4, 2008, in the United States Bankruptcy Court for the District of Delaware, in Wilmington, Delaware. The company's legal advisor with respect to the Chapter 11 filings is Young Conaway Stargatt & Taylor, LLP and its financial advisor is Allen & Company.
