Schwäbisch Hall municipality invests in modern technology for district heating
MAN Diesel & Turbo has won the contract to supply a 12V35/44 gas engine with dual turbocharger for a heat/power cogeneration unit in southern Germany. The new MAN unit has an output of 7.5 megawatts (MW) and will replace the existing two engines – each with an output of 3 MW – at the Schwäbisch Hall cogeneration unit which has generated electrical energy and heat for the local district-heating grid since 1997.
T
he plant offers a power production of 3,700 MWh and a thermal output of
3,000 plants.” Hajo Hoops, Senior Sales Manager in the Power Plants division of MAN Diesel & Turbo. comments: "Schwäbisch Hall Municipal Utilities are pioneers in the field of the energy transformation & decentralised generation.
"The decision to order from
MAN was made on the basis of the outstanding efficiency and flexibility of the system. It will also be possible to participate in the balancing energy market in the future; the existing district-heating storage components allow the decoupling of electrical and thermal energy-generation." "The new engine will achieve an electrical efficiency of 47%,

“The new engine will achieve an electrical efficiency of 47%, compared to 39% with the current units. This represents a 20% boost in efficiency.”
compared to 39% with the current units," confirmed Gebhard Gentner, managing director of Schwäbisch Hall Municipal Utilities. "This represents a 20% boost in efficiency. Along with state subventions for cogeneration units, this is the precondition for operating the plant economically." In terms of overall efficiency, the new system has an energy utilisation rate of around 90%. "High-efficiency technologies such as heat/power cogeneration make an
important contribution to con- trollable power generation in the context of the energy transformation," explains Gentner. "Schwäbisch Hall Municipal
Utilities generate power and heat with more than 50 cogeneration units at 30 sites."
