Hitachi Power Systems America (HPSA) was awarded a contract for the design and supply of a selective catalytic reduction (SCR) system with Tri-State Generation and Transmission Association for its Craig Generation Station, Unit 2, located in Craig, Colorado. The contract includes the design and supply of a SCR System for Craig Unit 2 which is a coal-fired steam electric generating unit with a net capacity of approximately 428 MW. The SCR system being furnished by HPSA will utilize Hitachi's catalyst, offering high NOx removal efficiencies over a wide operating load range. This technology will help Tri-State Generation meet or exceed its NOx reduction requirements, while keeping sulfur trioxide (SO3) emissions low. This system was designed for continuous operation throughout the year.
