Ludwigshafen CCGT plant
Since 1997, the combined-cycle gas turbine (CCGT) plant located on BASF's Ludwigshafen site has been supplying BASF with steam and RWE's interconnected grid with electricity. Ludwigshafen is the world's biggest interconnected BASF location, where some 350 chemical production facilities are closely interlocked across approximately ten square kilometres and, in many respects, are suppliers to and buyers from one another.
Since October 2012 the CCGT has been owned by BASF SE, and operated by RWE Generation.
Crucial component in the integrated energy-supply system
The CCGT plant is a crucial component in the integrated energy-supply system at the location whose job it is to cover the annual demand of approximately six billion kilowatt-hours of electric energy and 18 million tons of steam both efficiently and in line with the production facilities' availability requirements.
The plant concept
The plant consists mainly of two gas turbines, two unfired waste-heat steam generators and one back-pressure extraction turbine. Each gas turbine has an electric output of 162 MW. The steam turbine was designed for an electric output of 72 MW. In full-load operations, the plant – after deduction of its own requirements – generates 390 MW electric output and 533 t/h 6-bar steam.
