The Combined Heat and Power Alliance (CHP Alliance) is the leading national voice for the deployment of Combined Heat and Power (CHP) and Waste Heat to Power (WHP). We are a coalition of business, labor, contractor, non-profit organizations, and educational institutions with the common purpose to educate all Americans about CHP and WHP, and how CHP and WHP can make America’s manufacturers and other businesses more competitive, reduce energy costs, enhance grid reliability, and reduce emissions. We operated as the Alliance for Industrial Efficiency from 2010 to 2019, but in September 2019 we changed our name and refocused our mission on CHP and WHP. According to the U.S. Department of Energy, combined heat and power (CHP) and waste heat to power (WHP) could provide 20 percent of America’s electricity while cutting emissions and slashing energy costs for U.S. manufacturers and other businesses. The CHP Alliance leads its members’ education and advocacy activities with Congress and the Administration and state policymakers, develops coordinated communications strategies, and mobilizes members and affiliates to support expanded awareness of the use of CHP and WHP.
