Chambersburg peaking power plant

The Borough of 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.

“We sell all power to the local power grid, which has quite stringent rules for power plants delivering electricity. Having a quicker online time has made us more valuable in the eyes of the regional network operator,”
