These contracts also include a long-term operation support and maintenance agreement. The Claus power plant is located in Maasbracht, in southeast Netherlands.
Alstom will design and build the Claus-C unit 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 640MW steam turbine of Claus-B and integrate it into the new combined cycle.
The replacement of the old gas-fired boiler of the Claus-B by the three new GT26 gas turbines will increase the total output to 1,280MW from the current 640MW and reduce CO2 emissions by 40%. This repowering configuration will increase the efficiency of the plant from 39% to above 58%.
Philippe Joubert, Alstom’s executive vice-president and president for power systems, said: Alstom, as a plant integrator specialist will be providing Essent with a highly flexible plant in line with the stringent environmental regulations that are currently in place in the Netherlands.
