Comverge is an American privately held company that provides software, hardware, and services to electric utilities implementing demand response and energy efficiency programs.

Comverge was organized in 1997 as a Delaware corporation by Acorn Energy, Inc. At this point, the company made the strategic decision in 2002 to develop, own, and operate load management systems for the benefit of electric utilities.

Comverge has worked with a wide range of investor-owned, public power, and electric cooperative utilities.

Notable clients include Pepco Holdings Inc. (PHI), whose Energy Wise Rewards Program with Comverge recruited over 51 percent of eligible households in its Maryland service territory to participate;[1] and the Southern Maryland Electric Cooperative (SMECO), which had recruited 50 percent of eligible households into their CoolSentry program as of October 2013.

In 2012, Comverge saved its customers 32 gigawatt-hours (gWh) of electricity from June through September, which was equivalent to taking more than 30,000 homes off the grid for one month.
