The initial design of the Claus power plant in Massbracht originally consisted of the two gas-fired units A and B, from 1977 and 1978 respectively. Both had a generating capacity of 640 megawatts. In order to increase operational flexibility of the unit B (the project), we were assigned to act as owner’s engineer and technical advisor on behalf of Essent (now RWE Generation SE, NL) for the project. The Steam Turbine systems of Claus B were refurbished and reused and three new GT26 Gasturbines and Heat Recovery Steam Generators were added as a 3-on-1 CCGT.
Our owner’s engineer services included: project development, project management, tendering, contract award and management (EPC/multi-lot, LTSA), engineering review and site supervision. We also ensured compliance with health and safety policies and advised mobilization acitivies for later operation of the plant.
The project was completed ahead of schedule and with an excellent work-safety score. With our help, Claus B has been completely modernized and converted into Claus C, with a total 1,245 megawatts and an efficiency of 58.5 per cent (old Claus B had 40 per cent)
Power Plant Modernization
Over the last two decades, we supported various power plant modernization projects within the RWE Group. Aiming to keep the RWE generation fleet profitable and competitive, we assessed the techno-economic potential of upgrading plants by improving existing gas-fired plants (especially in UK / NL) or repowering and modernizing the coal-fired fleet in Germany. We applied modern technologies on gas turbines or water steam cycles, upgrading generators to enable those extra MW’s being safely and efficiently generated and supplied to the grid. We also supported the role-out of O&M solutions that brought major cost savings to the total fleet.
