FOR IMMEDIATE RELEASE:

Comverge Reports Year End 2008 Financial Results

Annual Revenue Growth Exceeds 35% for 4^th Consecutive Year

East Hanover, NJ: March 10, 2009 – Comverge, Inc. (NASDAQ: COMV), a leading provider of comprehensive smart grid, demand management, and energy efficiency solutions, announced fourth quarter and year-end financial and operating results for 2008.

Robert M. Chiste, Chairman, President and CEO of Comverge said:

“Comverge again demonstrated strong results in 2008, as we attained 40% revenue growth in a very tumultuous economic climate and increased megawatts under management by over 60%. This marks the fourth consecutive year that our revenue growth exceeded 35%. Our revenue visibility increased dramatically with estimated future revenues from long-term contracts currently exceeding $520 million, assuming regulatory approval of two contracts included in the make up of these revenues. In addition, our pipeline is growing rapidly, as we responded to RFP’s, in January alone, valued at more than $500 million. More utilities are partnering with Comverge for demand management solutions as they increasingly realize the most economic and cleanest megawatt is the megawatt never produced. With the recent nationwide emphasis on building the smart grid, we believe that we are at the forefront of the alternative energy sector by providing Strategic Utility Management through Innovation and Technology.”

Financial Summary:

Full year revenues were $77.2 million in 2008 compared to $55.2 million in 2007, a 40% increase. Fourth quarter revenues for 2008 were $33.0 million compared to $34.8 million in the fourth quarter of 2007, a 5% decrease. Revenues for both periods include revenues from our residential VPC contracts, which are deferred and recognized in the fourth quarter.

For the full year 2008, adjusted EBITDA was a loss of $5.1 million compared to income of $0.5 million for 2007. Adjusted EBITDA for the fourth quarter of 2008 was positive $12.7 million compared to positive $13.3 million for the fourth quarter of 2007. Adjusted EBITDA is earnings before interest, taxes, depreciation, amortization, non-cash stock compensation expense and non-cash impairment charges (see Schedule 5 – Reconciliation of Non-GAAP Financial Measure to the Most Directly Comparable GAAP Financial Measure).

Net loss for full year 2008 was $94.1 million, or $4.45 per share basic and diluted. Included in the 2008 net loss was the non-cash impairment charge recorded in the third quarter of 2008 for goodwill and certain intangible assets related to our acquisition of Enerwise Global Technologies, Inc., of $75.4 million, or $3.52 per share basic and diluted after a $1.0 million tax benefit. Net loss for full year 2008, excluding the impact of the impairment charge, was $19.7 million, or $0.93 per share basic and diluted, compared to a net loss of $6.6 million, or $0.46 per share basic and diluted for full year 2007. Net income for the fourth quarter of 2008 was $6.1 million, or $0.29 per share basic and $0.28 per share diluted, compared to net income of $7.6 million, or $0.38 per share basic and $0.36 per share diluted for the fourth quarter of 2007.

Entered into a new $25 million senior credit facility with Silicon Valley Bank.

Recent Developments:

In 2009, Comverge has:

Entered into a five year contract with Pepco Holdings, Inc. to provide full turnkey services, including an AMI-enabled demand response hardware and software system, as well as installation and marketing services;

Announced the release of its Apollo® Demand Response Management System software platform;

Announced the delivery of its five millionth demand management device;

Appointed Larry Hagewood and Thomas Gutierrez to the Board of Directors.

Current Outlook:

We currently expect our full year fiscal 2009 revenues will exceed $90 million. Comverge’s management and Board of Directors use three metrics to measure the company’s operational progress: (i) megawatts owned under long-term contracts, (ii) megawatts managed under open market programs, and (iii) estimated future revenues from long-term contracts. We believe these metrics are the most important to the growth and long-term success of the company.

Our 2009 targets for growth in these metrics are:

-- Add a net 275 megawatts of capacity under long-term contracts;

-- Add a net 225 megawatts in open market programs; and

-- Add a net $150 million increase in the amount of estimated future revenues from long-term contracts.

As of the date of this release, we have 866 megawatts under long-term contract which will contribute to contracted future revenues of $522 million. Of these amounts, 165 megawatts of capacity under long-term contracts representing an expected $114 million in contracted future revenues, are still awaiting regulatory approval. In the event we receive regulatory approval on these 165 megawatts, and including new megawatts acquired in open market programs and a new turnkey contract awarded during the first quarter of 2009, our total megawatts managed will be 2,620 megawatts.

The above statements are based on current expectations. These statements are forward-looking and actual results may differ materially. The Company assumes no obligation to publicly update or revise its outlook. Investors are reminded that actual results may differ from these estimates for the reasons described below under the caption “For Comverge Investors” and in our filings with the Securities and Exchange Commission.
