In 2016, Perennial Power acquired interests in West Deptford Energy Holdings, LLC, which owns West Deptford Power Station, from an affiliate of LS Power Group, a power developer in the United States. LS Power affiliates continue to participate in the West Deptford Power Station as a fellow owner and as the project's operator.
West Deptford Power Station is a natural gas-fired combined-cycle power generation facility with a capacity of 751 megawatts. Since its commercial operation in November 2014, it has supplied power to the northeastern part of the PJM in the United States (Pennsylvania-New Jersey-Maryland). PJM has the largest wholesale electricity market in North America. West Deptford Power Station is well positioned as one of the most advanced power sources in northeastern PJM and is expected to play an important role in maintaining a stable and environmental friendly power supply in that region at a time when there are many anticipated retirement of coal-fired and nuclear power stations.
Hermiston Generating Plant (HGP) is located in northeastern Oregon, nine miles south of the Columbia River. HGP is a 474 megawatt highly reliable modern natural gas fueled power plant that provides power for nearly 500,000 households in the Pacific Northwest. The plant also provides steam to Lamb-Weston's adjacent potato processing plant.
