BASKING RIDGE, N.J., January, 2014 – Hitachi Power Systems America, Ltd.
(HPSA), a wholly owned subsidiary of Hitachi America, Ltd., today announced that it
has been awarded 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 approximately 428
MW. The Craig Station fires Colorado low sulfur bituminous coal as its primary fuel.
SCR systems reduce nitrogen oxide (NOx) emissions, a contributor to the formation of
ozone and smog. The SCR system being furnished by HPSA will utilize Hitachi’s
state-of-the-art catalyst, offering high NOx removal efficiencies over a wide operating
load range. This leading edge technology will help Tri-State Generation meet or
exceed its NOx reduction requirements, while keeping sulfur trioxide (SO3) emissions
low. This highly reliable system is being designed for continuous operation throughout
the year.

Henry Bartoli, president and CEO of HPSA stated, “We are extremely pleased to have
been selected by Tri-State Generation to execute this project and look forward to
supporting Tri-State Generation’s efforts to supply its customers with clean, efficient,
low cost electricity. This contract represents another important milestone in the
deployment of Hitachi’s proven technologies to the U.S. markets and further
establishes HPSA’s important leadership position as an industry leader in the
reduction of emissions from power generation facilities.”
