We own 8,337 megawatts of efficient thermal generation across the West. Currently 26 units use coal to boil water and create steam, which turns the turbines to generate power. Three more units at our Gadsby Plant use gas to create the steam needed by their turbines. The Blundell plant also uses steam to power its turbines, but that steam is created from water heated naturally by magma and pumped to the plant from as deep as 20,000 feet below the Earth’s surface. Of our thermal generation, 1,230 MW is fueled by natural gas in simple-cycle and combined-cycle systems that employ combustion turbines, similar to jet engine technology. Two of those plants and three units at Gadsby have joined our fleet since 2005. So our emission-free 1,158 MW capabilities in hydro power and 1,793 MW in renewables – that rely on the forces of nature – are reinforced by these more traditional thermal resources fueled by coal and gas. We demonstrate our environmental stewardship through our choices in low-sulfur coal supplies and by the emission controls we build into or retrofit onto our thermal plants. We believe that responsible environmental management is good business because it benefits our customers and improves the quality of the environment in which we live. That makes for a resource portfolio that is well balanced and capable of meeting the needs and preferences of our 1.7 million customers across six Western states.
