Strategic Electrification Roadmap for Buildings and Transportation in the District of Columbia
On behalf of the District of Columbia’s Department of Energy and Environment, Synapse Energy Economics led a team of several consultants, including Siemens, Integral, and Nelson Nygaard, to develop an electrification roadmap for buildings and transportation in the District, consistent with the District’s carbon neutrality policy and objective to reduce energy use in buildings by 50 percent by 2032.
The team developed electric load impacts associated with the electrification pathway in each sector. We then examined the grid impacts of electrification on several specific distribution substations and circuits in 2032 and developed both “wires” and “non-wires” solutions to maintain reliability despite increases in load. We estimated the potential for energy efficiency, demand response, and battery storage measures to mitigate the potential distribution grid constraints and compared that portfolio with reconductoring and construction of new feeders.
The District of Columbia's Department of Energy and Environment filed the report as part of Formal Cases 1130 and 1167 in April 2023.
