We provide electricity to nearly 340,000 customers and natural gas to about 300,000 customers across 30,000 square miles and four northwestern states.
Our diverse generation system allows us to produce energy that consistently ranks among the nation’s most competitively priced. It includes:
- Eight hydroelectric generating plants on two rivers.
- Coal, natural gas and wood-waste combustion plants in five eastern Washington, northern Idaho, and eastern Montana locations.
- Pipeline access to domestic natural gas, as well as Canadian supplies, that allows us to capture market opportunities and increase cost efficiencies for our growing number of natural gas customers.
