The first two eGPUs are being used on the apron by AeroGround, a wholly owned subsidiary of Munich Airport, and 20 will be in use by next month.
Two thirds of the GPUs at Munich Airport have been switched to electric units, which is expected to save around 8,000 tons of CO2 annually.
Switching to electric units will cut emissions and noise, improving working conditions on the apron and reducing pollution.
Munich Airport is investing heavily in electric-powered vehicles, having taken delivery of 10 electric passenger buses earlier this year.
Another 27 will enter service by the end of the year and there is the option for another 25.
The acquisition of the eGPUs was supported with €5.6 million by the Federal Ministry for Digital and Transport as part of a funding programme to switch to sustainable power sources.
The funds were split between Munich Airport and AeroGround.
