25 September 2006 — ALSTOM has won a contract worth over €700 million with US-based global energy company AES Corporation to build a turnkey 670 MW clean coal power plant in Bulgaria.
ALSTOM will provide an integrated clean power solution including engineering, procurement, construction, and in-house manufacturing of the main equipment for the Maritza East 1 lignite-fired power plant, located near the town of Galabovo in the south-east of the country.
The plant will achieve emissions levels below those required by the EU Large Combustion Plant Directive. It will be equipped with ALSTOM advanced lignite-firing pulverized coal boilers using state-of-the-art low NOx burners.
In addition to the boilers, emissions control will be achieved with post-combustion equipment from ALSTOM. The limestone-based wet flue gas desulphurisation (wet FGD) system will achieve 98 percent sulphur dioxide removal. The electrostatic precipitator (ESP) will limit particulate emissions.
The plant will feature other ALSTOM technology, including two 335 MW
turbine-generator sets and TOPGAS turbogenerators, as well as coal and ash handling systems, electrical, information and control systems and balance of plant.
Maritza East 1 will be the first large-scale power project to be built in Bulgaria for the last 20 years and is planned to start commercial operation in 2009.
