The utility, which serves 1 million electric customers and over 750,000 natural gas customers in 11 counties of the US, has the Whatcom County facility from Tenaska Washington Partners.
The power plant employs combined-cycle, co-generation technology that can generate electricity first from its natural gas-fired turbines and then from a steam-driven turbine.
Built in 1994, the generating facility is adjacent to a Phillips 66 oil refinery about five miles west of Ferndale. Through 2011, the utility had purchased the plant’s power output from Tenaska.
With the latest transaction, the energy company has obtained more than 2,100MW of power-generating assets over the past 10 years.
Commenting on the acquisition, Puget Sound Energy senior VP Paul Wiegand said, "With the addition of this plant to our supply portfolio, our customers gain another cost-effective, environmentally responsible source of power."
The firm owns three other natural gas-fired power plants, with a combined generating capacity of 439MW, in Whatcom County, US.
