Book Description

Plymouth Energy, L.L.C. (Plymouth Energy) proposes to construct and operate the Plymouth Generating Facility (PGF), which would be a 307-megawatt (MW) natural gas-fired, combined cycle power generation facility on a 44.5-acre site 2 miles west of the rural community of Plymouth in southern Benton County, Washington. Plymouth Energy has proposed that the PGF would be interconnected to the Bonneville Power Administration's (BPA's) proposed McNary-John Day 500-kilovolt (kV) transmission line at a point approximately 4.7 miles west of BPA's McNary Substation. This tie-in to the McNary-John Day line would be approximately 0.6 mile to the north of the project site. Natural gas would be supplied to the project by an 800-foot pipeline lateral from the Williams Northwest Gas Pipeline Company (Williams Co.) Plymouth Compressor Station, which is located adjacent to the plant site. Water for project use would be supplied from a groundwater well whose perfected rights have been transferred to the project. A small additional quantity of water to meet plant peak needs would be obtained by lease from the neighboring farm operation. Wastewater resulting from project operations would be supplied to the neighboring farm for blending with farm-supplied water, and then used for crop irrigation. Electricity generated by the PGF would be delivered to the BPA electric grid via a new transmission interconnection for transmission of energy to regional purchasers of electricity.
