Chambersburg peaking power plant

Chambersburg + Wärtsilä

Energy optimisation and lifecycle solutions in Chambersburg

The Borough of Chambersburg (Franklin County) has approximately 21,000 residents and is part of the State of Pennsylvania. Chambersburg is an exceptional municipality in Pennsylvania since they have their own power plant. As a municipal electric utility, the plant is owned and operated by and for the residents of the community. By making and selling power, Chambersburg has lower net energy costs than communities that buy all their power.

Chambersburg updated the automation system of their 23-megawatt power plant consisting of four Wärtsilä 18V32DF dual-fuel engines to achieve better reliability. The upgrade enables faster ramp-up times and minimizes start failures, which are key features for getting the power plant online quickly. Other benefits are lower NOx-emissions, a slightly improved heat rate and noticeably less cylinder knocking.
