Alstom and E.ON Benelux Contract Covers Steam Turbine for Netherlands Power Plant

Posted on May 27, 2009

Alstom and E.ON Benelux have agreed on a contract to supply the steam turbine unit for the new fossil-fuel power plant at the Maasvlakte power station in Rotterdam. Like the existing Maasvlakte power plant, the new unit will be able to co-fire biomass and is being designed for subsequent retrofitting with carbon capture technology. Strategically located near the North Sea and the Rotterdam harbour area, the new plant can profit from seawater for cooling and deep waterways for supply of coal and biomass.

Alstom will provide a 1110 MW steam turbine generator package and will carry out transport to the site, full erection, commissioning and trial runs. The package includes 1 steam turbine with heat extraction, generator and condenser, HD5X8 + MD5X + 3XND49AU/B + 50WT25E-160, and 1 x boiler-feed-pump-turbine (BFPT 245) + condenser. This technology will contribute to a net efficiency of 46%, compared with a European average of 36%, thus improving the environmental performance significantly. The new Maasvlakte power plant is scheduled to start commercial operation from 2013.

"This new generation of steam turbine generator technology, resulting in high plant efficiency, is key to significantly reducing CO2 emissions in coal-fired power plants while considerably improving power plant economics," commented Guy Chardon, senior vice president, Alstom Power Thermal Products.

In this project we combine state-of-the-art technology”, says Aris Blankenspoor, general project manager of E.ON’s Maasvlakte Power Plant 3 project. “New boiler technology, with super critical steam parameters of 285 bar and 620°C, is key to an efficiency improvement of about 20% per kilowatt. We need less coal for the same amount of energy. Our flue gas treatment results in the lowest possible specific emissions e.g. for dust, SO2, CO2 and NOx. Thus realizing a coal-fired power plant with emissions, comparable with gas-fired units.”
