General Description of Project

Humboldt Bay Generating Station (HBGS) is located at 1000 King Salmon Avenue, Eureka, California. The project is located on 5.4 acres within a 143-acre parcel currently occupied by the existing PG&E Humboldt Bay Power Plant.

HBGS is a load following power plant consisting of ten (10) natural gas-fired Wartsila 18V50DF 16.3 megawatt (MW) reciprocating engine-generator sets and associated equipment with a combined nominal generating capacity of 163 MW. HBGS is also capable of running on California Air Resources Board (CARB)-certified diesel fuel in order to ensure local area reliability during instances of natural gas curtailment in the region as required by the California Public Utilities Commission (CPUC) and PG&E's CPUC Gas Tariff Rule 14.

This project is a replacement of the original 105 MW Units 1 and 2 and the two 15 MW Mobile Emergency Power Plants (MEPP) at PG&E's Humboldt Bay Power Plant site. HBGS was certified on September 24, 2008 and began commercial operation on October 1, 2010.

Energy Commission Facility Certification Process

The California Energy Commission is the lead agency (for licensing thermal power plants 50 megawatts and larger) under the California Environmental Quality Act (CEQA) and has a certified regulatory program under CEQA. Under its certified program, the Energy Commission is exempt from having to prepare an environmental impact report. Its certified program, however, does require environmental analysis of the project, including an analysis of alternatives and mitigation measures to minimize any significant adverse effect the project may have on the environment.
