Wood Group, an international energy services company, has received an engineering, procurement and construction (EPC) contract, valued at approximately $152m, from GWF Energy to construct and commission the conversion of the Tracy Peaker power plant in Tracy, California.

GWF is converting the plant to a combined-cycle facility in support of a new power purchase agreement with Pacific Gas & Electric (PG&E).

The existing facility, which consists of two GE Frame 7EA gas turbine generators, will be converted to combined-cycle operation through the turnkey design and installation of two heat recovery steam generators and a single steam turbine generator, an air cooled condenser, and related balance of plant equipment.

Upon completion, the converted 336MW Tracy combined-cycle plant will offer additional flexible electric generating capacity for PG&E and its customers, Wood Group said.
