Hitachi unit to supply SCR system to Tri-State Generation and Transmission

Hitachi Power Systems America Ltd., a unit of Hitachi America, Ltd., won a contract for the design and supply of a selective catalytic reduction (SCR) system including Hitachi’s proprietary catalyst with Tri-State Generation and Transmission Association, Inc. 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 about 428 MW.

The Craig Station fires Colorado low sulfur bituminous coal as its primary fuel. SCR systems reduce nitrogen oxide emissions, a contributor to the formation of ozone and smog. The SCR system being furnished by HPSA will use Hitachi’s catalyst, offering high nitrogen oxide removal efficiencies over a wide operating load range.

This environmental technology will help Tri-State Generation meet or exceed its nitrogen oxide reduction requirements, while keeping sulfur trioxide emissions low.
