Partner Profile
Philadelphia's Greenworks Philadelphia plan set a goal to purchase and generate 20 percent of the electricity used in Philadelphia from alternative energy sources. As America’s fifth largest city working toward becoming the greenest city in America, the City purchases renewable energy covering approximately one percent of the usage of the municipal government. The City’s first City-owned solar array came online in mid-2011, at the Southeast Water Pollution Control Plant. This 250 kW Solar PV project produces approximately 340,000 kWh of solar power each year. In March of 2012, the City’s water and wastewater utility, Philadelphia Water, installed a NovaThermal Energy geothermal unit, which uses sewage as a sustainable heat source for the plant, and is the first installation of its kind in the nation. This installation produces the equivalent of about 450,000 kWh per year when it runs for a full heating season. Philadelphia Water also installed and began running a 5.6 MW Biogas Co-generation facility in December 2013. The system generates approximately 28,000,000 kWh/year from excess gas captured from digesters at the Northeast Water Pollution Control Plant.

Over time, the City plans to move towards actively supporting more local renewable energy generation by using budgeted dollars for voluntary renewable energy certificate (REC) purchases from local renewable energy projects. While the dollars spent on voluntary RECs will be the same, the number of RECs the City will be able to purchase and retire will likely be less due to the higher cost of locally generated RECs. However, the City views this approach as valuable as it invests in job creation, reduced grid congestion, increased fuel source diversity, and reductions in carbon emissions from scope 2 (indirect) sources in the city and our region.
