23 August 2006 - Alstom has been awarded a contract for the engineering, design and construction of the boiler and air quality control equipment for a new 850 MW advanced high-efficiency coal-fired power plant for US utility Kansas City Power & Light (KCP&L). This contract is worth $700m.
When completed in 2010, this unit will generate extremely clean and reliable electricity from the US' abundant coal resources.
Located at the Iatan Generating Station near Weston, Missouri, US, the new unit, known as Iatan 2, will be Alstom's largest sliding pressure supercritical coal-fired plant in the US. The award also includes integrated environmental control systems for the new unit and major retrofit work to the environmental control systems of Iatan 1, the existing 670 MW subcritical coal-fired unit at the plant. Burns & McDonnell, headquartered in Kansas City, Missouri (US), has been named the Owner's Engineer.
The new Iatan 2 boiler, equipped with Alstom's low NOx tangential firing system and designed to burn low-sulphur Powder River Basin Coal, will also feature state-of-the-art post-combustion environmental technologies including a selective catalytic reduction (SCR) system, wet flue gas desulphurization (FGD) system and fabric filter (FF) to control emissions.
The design basis of Unit 2 is an advanced high-pressure, high-temperature steam cycle, which will substantially increase plant efficiency and thereby also minimise emissions and fuel costs. KCP&L will upgrade the environmental performance of Iatan 1 with the retrofit of Alstom's Air Quality Control System (AQCS), including an SCR, wet FGD and FF to control and reduce NOx, SO2, mercury and particulate matter emissions. The Iatan 1 upgrades will be completed by the summer of 2009.
"Selection of Alstom for the boiler and AQCS components of Iatan 2 is a crucial step toward completion of this important regional asset," said Bill Downey, President and CEO of KCP&L. "The addition of Iatan 2, along with the planned environmental upgrades to Iatan Unit 1 will meet growing regional energy needs, while substantially improving air emissions at that site. With this agreement, the largest single component of our Comprehensive Energy Plan is on track to meet its goals envisioned in the plan."
Philippe Joubert, President of Alstom's Power Turbo Systems/Power Environment Sector, commented: "Alstom will provide a solution for Iatan 2 that integrates the latest boiler technology with post-combustion air emissions control equipment. For Iatan 1, we will integrate several components to bring the plant up to a very high environmental standard. Our expertise in both the individual components and in integrated engineering was an important factor in Alstom winning this contract."
