Wind Powers 35% of Washington DC Government

July 27, 2015 By Linda Hardesty

350196The District of Columbia signed a 20-year power purchase agreement (PPA) with Iberdrola Renewables that will supply 35 percent of the government’s electricity with wind power.

Under the PPA, the Department of General Services (DGS), which manages the District’s portfolio of government buildings, will purchase the entire output of Iberdrola’s South Chestnut 46 MW wind farm in southwestern Pennsylvania. This will supply Washington with about 125,000 MWh every year.

The wind power will be drawn from 23 turbines located on private property in three Pennsylvania townships – Georges, Springhill and Wharton.

Since 2012, the District has purchased 100 percent green power via Renewable Energy Certificates (RECs). Under the new wind PPA, the District will directly receive wind power for 35 percent of its electricity demand. The District government will continue to use RECs for the remainder of its electricity needs, ensuring that 100 percent of its electricity consumption remains emission-free.
