    Optionally, additional GenericAssetTypes can be created using:
    flexmeasures db upgrade +1 -x '{"name": "waste power plant"}' -x '{"name": "EVSE", "description": "Electric Vehicle Supply Equipment"}'
    The +1 makes sure we only upgrade by 1 revision, as these arguments are only meant to be used by this upgrade function.
