16 June 2008 - Alstom has signed contracts worth €1bn ($1.54bn) with Dutch utility Essent for the repowering of Claus B and the construction of Claus C, resulting in a 1280 MW GT26-based combined-cycle power plant.
These contracts also include a long-term operation support and maintenance agreement. These orders should be booked in the second half of fiscal year 2008/09. The Claus power plant is located in Maasbracht, south east of the Netherlands.
Alstom will design and build Claus C next to the existing power plant and provide the main components, including three GT26 gas turbines along with TOPAIR turbogenerators, heat recovery steam generators, ALSPA distributed control system and the relevant auxiliary equipment. Alstom will also retrofit the existing 640 MW steam turbine of Claus B and integrate it into the new combined cycle.
The replacement of the old gas fired boiler of Claus B by the three new GT26 gas turbines will increase the total output to 1,280 MW from the current 640 MW and reduce CO2 emissions by 40 per cent.
This repowering configuration will increase the efficiency of the plant from 39 per cent now to above 58 per cent, making it one of the most efficient combined-cycle power plants available today.
