River Road generating plant

In the River Road plant, we use "combined-cycle" technology to produce power. This highly efficient process produces the most electricity for the amount of fuel used. The plant was completed in 1997 and is capable of providing about half of the power needed by our customers.

Minimal environmental impact
Air emissions are monitored continuously and are so low that the facility is defined by state law as a minor source of emissions. The controls include a selective catalytic reduction system for control of nitrogen oxides that result from burning natural gas. Carbon monoxide emissions are controlled by using combustion controls and an oxidation catalyst.

Water used in the plant is recycled extensively, but must be replaced on a continuous basis. Two wells at the plant site serve as the water source. Water cycled through the plant is used to enhance nearby wetland areas and also to water lawns and landscaping at the nearby Vancouver Lake and Frenchman's Bar parks. Water not used for these purposes is discharged directly into the Columbia River.
