Wärtsilä Corporation, a leading global provider of power
plants for decentralized power generation, was selected to deliver a
163 MWe gas-fired power plant to Pacific Gas and Electric Company
(PG&E), one of the largest gas and electric utilities in the United
The plant will be located in Humboldt Bay near Eureka in northern
California and is expected to enter commercial operation by mid-
2009. PG&E selected Wärtsilä’s technology in order to repower their
existing Humboldt Bay plant. The new facility will be 35% more
efficient with 90% fewer air emissions. The agreement is subject to
the approval of the California Public Utility Commission and
environmental permits issued by the California Energy Commission.
"This project marks a significant entry for Wärtsilä in California.
Wärtsilä gas engine technology is an outstanding choice for the
utility’s energy shaping requirements, as well as for the state of
California’s increasing environmental concerns. Our technology offers
high simple cycle efficiency on full and part load as well as other
ancillary service benefits that make the Wärtsilä solution a natural
choice for this operation," says Mr. Frank Donnelly, Vice President,
Power Plants, Wärtsilä North America.
For the Humboldt Bay power plant, Wärtsilä will deliver 10 Wärtsilä
18V50DF lean-burn dual-fuel engines on an engineering, procurement
and construction (EPC) basis. The engines will be fuelled by natural
gas, and will be capable of using fuel oil as back-up during times of
natural gas curtailment. The 163 MW plant will produce reliable
electricity for the local grid in California’s north coast. The plant
will produce enough electricity to serve roughly 125,000 California
Wärtsilä’s dual fuel engine technology - a competitive and popular
alternative to gas turbines
The Wärtsilä 50DF lean-burn dual-fuel engine is the most powerful gas-
burning engine on the market today and its design incorporates both
low emissions and high fuel efficiency, making it a competitive
alternative to gas turbines. It has become a popular engine for power
plant installations in countries all over the world. It is available
with up to 18 cylinders giving up to 16.64 MWe in continuous base-
load operation. The 50DF features a 7608kJ/kWh heat rate which is
equivalent to an overall thermal efficiency of 47.3% at the busbars.
In the event of loss of gas pressure, the engines switch over to the
back-up fuel oil. The engines are fully capable of automatically
changing from gas to back-up liquid fuel instantly if the gas supply
is interrupted while continuing to deliver full power. When the gas
supply is restored, it is then possible to immediately switch back to
