MAN Energy Solutions has won the contract to provide a new combined-heat-and-power (CHP) solution for Ben Gurion Airport in Tel Aviv, Israel. As the future main energy source, a dual-fuel engine MAN 9L51/60DF will supply the airport with 9.2 MW of electrical energy. The engine will primarily run off a domestic natural-gas supply with plant hand-over – upon its construction by Israeli company, Telemenia – planned for the end of 2019.
The power-plant engine will not only generate electricity, but will also contribute to the airport’s air-conditioning system through combined-heat-and-power generation. Instead of a conventional, compression chiller powered by electricity, the air-conditioning system will exploit heat generated by the engine to provide cooling.
The cogeneration solution not only increases the plant’s efficiency to over 70%, but the airport will also save on the electricity that would otherwise have been required to operate the chiller.
An indispensible solution
With more than 16.5 million passengers a year, Ben Gurion Airport is the largest and most important airport in Israel, making a reliable energy supply indispensable. The operation of the new facility will mean that the airport will no longer draw its energy from the national grid but, rather, will operate independently of the public power supply.
In order to meet high safety standards, the airport’s energy supply must be assured in the event of any crisis. Accordingly, the reliability of the technology used is of great importance. Thanks to its dual-fuel capability, the MAN 9L51/60DF engine will remain fully operational, even during any disruption to its gas supply.
