E.ON edis AG along with a team applied for a contract to supply heat, cold, power and emergency current to the International Berlin-Brandenburg Airport (BBI).
At the moment of tender, BLS Energieplan GmbH was a part of this team as a concept creator. After the contract award to E.ON edis, BLS Company was appointed as the planning department for the total large project of energy generation within in Berlin-Brandenburg. In contrast to the airport itself, the system was accepted and has been in operation since 2012.
CHP plant with 4 x 2 MW electric output and boiler units (2 x 10 MW) were implemented as planned. Cold is generated by two compression refrigerating machines (2 x 5.6 MW) and two absorption machines (2 x 1.4 MW) driven by exhaust gases of engines and thus achieve a high COP value exceeding 1.3. The cooling systems were supplemented with a central 3,500 m3 cold accumulator.
