The Future of Solar PV in the District of Columbia
On behalf of the Office of the People's Counsel for the District of Columbia, Synapse performed a Ward-level analysis of three future solar scenarios for the 2019-2041 timeframe. Using geospatial and economic analysis, Synapse also calculated the likely mix of private and community solar for the District, as well as the likely mix of rooftop, parking lot, and ground-mount solar through the study period. Based on the scenarios developed, Synapse recommended courses of action to help the District meet its ambitious solar carve-out goal (10% in-District solar by 2041). Finally, Synapse conducted a rate impact assessment of each solar scenario to determine which has the best impact on ratepayers in the District. Synapse recommended the District government closely monitor progress of the solar installations relative to the carve-out, as benefits are greatest if compliance is achieved early in the study period.
