Washington D.C.'s Rebates and Incentives for Solar Energy Systems

Washington D.C., the permanent and autonomous home our our federal government, has ironically average renewable energy standards. Symbolic of the fact that U.S. states are far outpacing the feds in the green energy race, D.C. is taking small steps to incorporating solar and other renewable resources into energy needs. In 2005 the District implemented its own Renewable Portfolio Standard (RPS) which requires that by 2022 at least 11% of electricity come from clean energy sources. This is a fairly average standard, but at least it is a standard. Uniquely, part of D.C.'s RPS dictates that nearly 37% of that electricity be derived from solar power--good news for solar enthusiasts!

Around that same time, District lawmakers developed The Reliable Energy Trust Fund to promote the used of renewable technologies in all sectors. It is this fund that supports Washington D.C.'s sole residential incentive program:

The Renewable Energy Demonstration Project (REDP)

• This grant program offers funds to homeowners interested in installing a solar photovoltaic (PV) electric system. Other solar technologies, such as solar space and water heating, are noticeably absent.
• Awards for residential applications peak at $3.00/watt up to a 3kW system, with an incentive maximum of $9,000.
• However, funds are limited. For the current round of funding (deadline August 15, 2008) there is only $150,000 available. This funding covers all sectors, including commercial and industrial. Because of the lack of funding current applicants are being placed on a waiting list for funds to be appropriated in what will be round five of the grant project.
• For more information and an application, see the REDP website.

District of Columbia - Net Metering

• D.C.'s net metering law addresses solar thermal and PV electric systems. The law encourages the use of smart meters, or meters that record electrical flow in both directions. Utility companies (of which D.C. has but one--Pepco) may install a second meter but must cover the cost.
• Net excess generation (NEG) must be credited, at the full-retail rate, to the customer's bill at the end of each month.
• Utilities must offer customers a standard interconnection agreement formulated by the D.C. Public Services Commission.
