The Green Energy Solution is Right Under your Feet

Vicinity feeds the Philadelphia district systems with low carbon, green steam generated in our combined heat and power (CHP) facilities. Our CHPs produce electricity while simultaneously capturing waste heat that would otherwise be lost under conventional means. This waste heat is converted to green steam and supplied to our customers through our vast underground network, providing heating, cooling, humidification and sterilization to our customers.

Biogenic Fuels - Circular Economy

Integrating Renewable Energy Into Our Fuel Mix as an Alternative ​to Fossil Fuels

Vicinity Energy centrally produces and distributes steam, hot water and chilled water to over 230 million square feet (nearly eight square miles) of building space nationwide. Now, in partnership with Lifecycle Renewables, Vicinity will begin to integrate LR100™ across each of its facilities over time. Permits have already been acquired and the biogenic fuel tested in Philadelphia, with implementation in other districts on the immediate horizon. A truly circular solution, the wastes discarded by the local food service industry will now be used to heat and cool businesses and institutions in the same city.

The Benefits of Transitioning to LR100™

12,200 tons

Significantly reducing Vicinity’s distillate fuel use, cutting carbon emissions by 12,200 tons, or the equivalent of removing 2,650 cars from Philadelphia’s roads each year

600,000 Gallons

Recycling 600,000 gallons of food service industry waste oil (the average person consumes approximately 1.5 gallons of oil a year) into energy, that would otherwise be discarded in landfills or city sewers


Reducing greenhouse gas emissions by over 80% versus distillate fuel, improving local air quality through reductions in nitrogen oxides, sulfur oxides and particulate emissions compared to traditional heavy fuel oils


Expanding Lifecycle Renewables’ operations in Philadelphia, resulting in job creation, recycling programs and cost savings for local restaurants, and sustainability benefits for the community

How District Energy Works

District energy is an innovative and resilient energy solution that uses a centrally located facility, or facilities, to generate thermal energy—heat, hot water or chilled water—which is then transported through highly insulated underground pipes directly to nearby buildings, avoiding the need for boilers, chillers and cooling towers in individual buildings. Watch the video to learn more about how district energy works.
