MAN Energy Solutions has announced that it has fully commissioned a new 7.5MW CHP plant for Schwäbisch Hall Municipal Utilities in southern Germany. The company was contracted to supply a MAN 12V35/44G TS gas engine to replace the two previous engines, each of which had an output of 3MW. The company said that the engine’s two-stage turbocharging design makes the 7.5MW unit particularly efficient, and that as a result, the Schwäbisch Hall CHP plant now achieves a fuel efficiency of up to 90 per cent.
Gebhard Gentner, Managing Director of Schwäbisch Hall Municipal Utilities, said: “The new engine will achieve an electrical efficiency of 47 per cent, compared to the 39 per cent of the previous units. This means a 20 per cent increase in the efficiency of the plant as a whole, thereby fulfilling the requirements stipulated in the German CHP Act for the plant to be operated commercially. High-efficiency technologies make an important contribution to controllable power generation in the context of the energy transition.”
