SCHEDULE 13D

Page 12 of 18 Pages

Item 4.

PURPOSE OF THE TRANSACTION.

The Reporting Persons originally acquired the Shares for investment in the ordinary course of its business because the Reporting Persons believed that the Shares, when purchased, represented an attractive investment opportunity.

On August 2, 2011, Ardsley sent a letter to the Chairman of the board of directors of the Company (the "August 2, 2011 Letter") encouraging the Company to make certain changes to the Company's structure and strategy, including, exploring a sale of the Company, reducing corporate overheard and making its financial objectives public. In addition, Ardsley asked the board of directors of the Company to suspend any dilutive capital activity until the foregoing changes have been made to the Company's structure and strategy. This summary of the August 2, 2011 Letter does not purport to be complete and is qualified in its entirety by reference to the text of the August 2, 2011 Letter, a copy of which is attached hereto as Exhibit 2 and is incorporated herein by reference. The Reporting Persons have had, and expect to continue to have, discussions with management, other shareholders of the Company and other relevant parties concerning the business, operations, management, governance, strategy and future plans of the Company.

Except as set forth herein or as would occur upon completion of any of the actions discussed herein, the Reporting Persons have no present plan or proposal that would relate to or result in any of the matters set forth in subparagraphs (a)-(j) of Item 4 of Schedule 13D. The Reporting Persons intend to review their investment in the Company on a continuing basis and may engage in discussions with management, the board of directors, other shareholders of the Company and other relevant parties concerning the business, operations, management, governance, strategy and future plans of the Company. Depending on various factors including, without limitation, the Company's financial position and strategic direction, the outcome of the discussions and actions referenced above, actions taken by the board of directors, price levels of the Shares, other investment opportunities available to the Reporting Persons, conditions in the securities market and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Company as they deem appropriate including, without limitation, purchasing additional Shares or selling some or all of their Shares, engaging in short selling of or any hedging or similar transactions with respect to the Shares, voting for or against and expressing support for or against any proposals of the board of directors of the Company or other shareholders of the Company and/or otherwise changing their intention with respect to any and all matters referred to in Item 4 of Schedule 13D.

EXHIBIT 2

Mr. Alec Dreyer

Chairman of the Board

Comverge, Inc.

5390 Triangle Parkway, Suite 300

Norcross, GA 30092

August 2, 2011

Dear Mr. Dreyer:

Ardsley Partners and its affiliates today own 1.75m shares of Comverge common stock, representing over 6% of the company’s outstanding shares. We have built this position with the belief that the market is severely undervaluing the company’s market position, contracted backlog, and other assets.

While we disagree with the market, we also understand why it would make this determination. Through our interaction with various members of management since Comverge’s IPO in 2007, we have come to believe that the company’s officers and Board of Directors have not managed Comverge to near its full potential. With the understanding that the balance sheet of the company is now stretched to the point where additional capital will be necessary in the near future, we wish to suggest some corrective measures that would help to assuage the market that, indeed, the Board’s interests are aligned with those of shareholders.

It is also worth mentioning that the Board/shareholder alignment is not immediately apparent. Collectively, the Board (outside of Mr. Scott Ungerer’s affiliation with EnerTech Capital) own just 1.5% of outstanding common stock. For an outlandishly well-compensated Board that includes a successful venture capitalist, a former FERC commissioner, and several current and ex-officers of large public companies, this is not a vote of confidence that allows us, as your shareholders, to sleep well at night.

Thus, Ardsley will shortly file a Form 13D. In this capacity, and as one of your largest shareholders, we ask that the Board of Directors forestall any potentially dilutive capital activity until the following changes have been made to the company’s structure and strategy. These changes should take three forms:

The Board should hire a banker to explore the sale of the company.

The Board should instruct management to drastically reduce its corporate overhead to bring it in line with that of its peers. This should include significant salary cuts to both senior management and the board of directors, reflecting that Comverge is now a company with a $75m market cap.

After changes to the cost structure are finalized, Management must make its revised financial objectives public in the form of guidance and a path to profitability.

Sale of Company:

As we mentioned, it is Ardsley’s belief that Comverge’s assets are being dramatically underpriced by the market. We believe that this implies an exceedingly high cost of capital. In an environment where much larger and better-capitalized firms have entered hoping to capitalize on prospective growth, a high cost-of-capital is a Sisyphean weight to bear. This has been reflected in Comverge’s lackluster contract wins of late, and its inability to deliver satisfying results in the 2014-15 RPM auction held in the spring. It is difficult to compete when the likes of Honeywell, Johnson Controls, and Siemens are devoting significant resources to take share.

However, this apparent weakness is also a strength. Due to its early strategic positioning and the structure of the major demand response markets, Comverge now has amassed over $570 million of future revenue. This is revenue that, despite their considerable resources, Honeywell and its peers cannot win. And so, it makes sense that they will wish to accelerate their footprint in the demand response markets via selective acquisitions. As a market leader with high overhead, Comverge is an ideal acquisition target.

On 7/29/2011, Shareholder Advocates for Value Enhancement (SAVE) published a letter to the Board outlining a framework for an acquisition of Comverge for between $6.50-10/share. We agree with SAVE’s assessment and think that they are being appropriately conservative. We would encourage an outright sale of the company at these levels. We believe that the Board should immediately hire a banker to advise on such a transaction.

Cuts to Corporate Overhead:

Among the sample of seven peers in the chart below, average 2010 G&A expense as a percentage of revenue was 17.7%. Comverge’s was 33%. This should be an embarrassment to all company officials, and steps should be taken to immediately reduce this expense in line with industry standards.

	FY10 Sales		FY2010 G&A		FY2010 OpEx		G&A (% of Sales)			OpEx (% of Sales)
EnerNOC	$	280.16	$	53.58	$	109.11		19.1	%		38.9	%
Echelon	$	111.04	$	17.65	$	77.47		15.9	%		69.8	%
RuggedCom	$	93.97	$	10.22	$	38.87		10.9	%		41.4	%
LIME Energy*	$	95.72	$	25.88	$	26.47		27.0	%		27.7	%
Active Power	$	64.96	$	5.32	$	21.82		8.2	%		33.6	%
Power Secure	$	97.51	$	29.34	$	37.25		30.1	%		38.2	%
Orion Energy	$	92.46	$	11.43	$	27.50		12.4	%		29.7	%
Group Average								17.7	%		39.9	%
Top Quartile								10.3	%		28.7	%
Comverge**	$	119.39	$	39.36	$	63.67		33.0	%		53.3	%

Given the 2011 $140m revenue target represented to Partners For Growth in an exhibit to the most recent 10-Q, this G&A target should be $25m. Annualizing the Q1 financials, the current run rate is $41m. Thus, management should be charged with the elimination of $16m of annual corporate overhead.

In its recent pre-announcement, management stated that are taking measures to eliminate $4-4.5m of operating expense. This is a start, but not nearly enough.

We have several suggestions:

The Board of Directors is paid too much. Their annual retainer is $63k with $108k in recurring option grants. In a 2010 report prepared for the board of another Ardsley holding (of a similar size/sector as Comverge), the base board retainer was recommended at $35k/year with annual option grants of $5k. This recommendation was immediately adopted by the chair of the compensation committee, who had previously been the CFO of two Fortune 100 companies. Adopting this more reasonable compensation recommendation to Comverge’s eight person board would result in annual cost savings of over $1m per year, or $0.04/share. It would also send an important cultural signal to Comverge’s managers – that operational leanness is the new norm.

Management is also paid too much. The top seven most senior managers are under contract to make $2.0m in base salary alone. In addition, their contracts set forth cash and option bonus based off of three levels of performance: “Threshold,” “Target,” and “Maximum.” In academic parlance, this might be akin to ‘C’, ‘B’, and ‘A’ test scores. The chart below shows these contractual terms:

($000s)		2011		Cash Bonus (% of Base)			Cash Bonus ($)						Option Bonus (% of Base)			Option Bonus ($)						Total Comp ($)
Executive	Title	Salary		Threshold	Target	Max	Threshold		Target		Max		Threshold	Target	Max	Threshold		Target		Max		Threshold		Target		Max

Average		$	292																			$	840	$	1,119	$	1,368
% of 2011 Revenue			1.5%																				4.2%		5.6%		6.8%

As you can see, under “threshold” performance goals defined by the Compensation Committee, an additional $3.8m will be paid to these managers. At “target” levels, that bonus is $5.2m. Given that any bonuses were paid in an abysmal 2010, I suggest that “threshold” performance is a forgone conclusion. I do not know how the Board justifies average annual compensation of $840k (4.2% of overall company revenue) for ‘C’ students, but this must change. Reducing “threshold” bonuses by 75% would save the company nearly $2.9m, or $0.12/share. Under this plan, each manager would still make $430k for failing to meet their financial objectives. I’m sure that if this led to attrition, there will be plenty of candidates to take over these positions.

Comverge portrays to investors a culture of extravagancies. In a recent management meeting, the CEO, Blake Young, handed me a business card made of metal. I do not know how much these metal cards cost, but I can assume that it is orders of magnitude higher than the simple paper cards that we use at our (profitable) firm. More importantly, metal cards add no shareholder value and are a bad signal to investors. Comverge must immediately cut all non-essential expenditures. I would suggest the formation of an operating committee by the Board that would proactively seek out these cuts. This committee, of course, should not pay committee fees.

Merely implementing the specific suggestions that we mentioned, along with the $4.5m already targeted by management, would reduce Comverge’s G&A by $8.4m (to 22% of 2011 revenue). While this should not be the end goal, it would certainly be a down payment on credible Board action.

Financial Guidance:

At its last annual earnings call, Comverge management opted to withhold full year guidance to its investors. This snapped a four-year streak of issuing revenue guidance. What is particularly disconcerting is that management constantly trumpets the superior visibility and stability afforded by its long-term contracts. So why withhold guidance? When asked by investors (including Ardsley), management suggested that they wished to build credibility by only putting out guidance when they were sure of meeting it. While this argument may have had merit in March, it is now August. The idea that investors will give management future credibility based on their ability to ‘forecast’ revenues that have largely already been booked is, quite simply, paradoxical.

More importantly, management has refused to project a long-term path to profitability. They have been mulling an analyst day for nearly a year, and yet this event has been beset with delays and cancellations. The last time, the push-out was blamed on CFO David Mathieson’s hiring; how could a new CFO lay out a company’s path to profitability before he understood the business? That is a fair point, but the reverse is also true: investors should not be asked to purchase stock from a CFO who still is learning the business.

Thus, we charge management and Board with the following imperative: tell investors what they are buying before trying to sell them something.

In conclusion, our directive should be clear: before the Board dilutes its shareholders with an equity offering at a depressed level, it has the fiduciary duty to determine the true worth of the company by undertaking a well-publicized auction of the company. Concurrently, given that a sale is no certainty, the Board must take immediate steps to right-size corporate expenses, including Board expenses, to be commensurate with the size of the company. Finally, the company must take a more transparent approach towards investor communication by publishing short and long-term financial objectives on a regular basis.

Barring an immediate action plan addressing the above three points, we will reevaluate our position as a stock holder, reserving all of our rights as such.

With Kind Regards,
