Renewable Energy Demonstration Project (REDP)

May 04, 2009


The District of Columbia Renewable Energy Demonstration Project (REDP) was developed by the District Department of the Environment (DDOE) Energy Division -- formerly the D.C. Energy Office -- to increase the awareness and use of renewable-energy technologies by residents, businesses and institutions. In December 2006, a total of $450,000 from the D.C. Reliable Energy Trust Fund -- a public benefits fund administered through the DDOE and overseen by the D.C. Public Service Commission -- was made available for demonstration projects featuring solar photovoltaics (PV), wind, biomass-fired combined heat and power (CHP), fuel cells, small hydropower facilities, geothermal-electric facilities, and certain other renewable-energy resources. Under the fourth round of solicitations for renewable energy installations, a total of $150,000 is available. The fourth solicitation closed on August 15, 2008. Residential awards are limited to $3.00 per watt up to three kilowatts (kW), with a maximum award of $9,000. Non-residential awards are limited to $2.50 per watt up to 8 kW, with a maximum award of $20,000. Due to limited funding, applicants for round four funding will automatically enter a reservation queue for the next round of funding. Interested parties are encouraged to submit applications as soon as possible to reserve a place in line. A fifth found of REDP will soon be announced for fiscal year 2009. Due to tremendous demand, there may be additional funds available for the 2008 and 2009 program years. The REDP Grant Package is available at Contact the DDOE Sustainable Solutions Division for more information.
