Jonas, the smart apprentice of the Brandenburg Solar Park, picks up his mobile phone and taps four Clean Energy Packs in the charging cabinet of workshop with the Clean Energy Net app. The charging rack is connected to the inverters of the solar park through its Clean Energy Link and controls uploading, withdrawal and charging with electricity according to availability and demand. Jonas places the Clean Energy Packs in the large drawer under the loading bay of the electric service wagon, which has charged its remaining Clean Energy Packs through the charging cable overnight. After he has loaded his fully electrical tools on the loading bay, his boss gets behind the wheel and silently cruises into the vast solar fields.
Once there, Jonas unloads the autonomous electric lawnmower and inserts two Clean Energy Packs. Another tap on the app activates the two packs and connects them to the lawn mower, which mows the grass between the massive pillars of the stacked-up solar panels over the day. The boss takes another Clean Energy Pack and attaches a small adapter with a 230 volt socket. Then the master connects the powerful, portable welding gear and gets to work fixing the substructure beams that were broken in the last thunderstorm. The saw for replacement beams is connected directly to the 3-phase power socket of the service wagon, the grinder for oxidised contacts is connected right next to it.
At noon, the four Clean Energy Packs are discharged, but there is still a lot of work to be done; Jonas gets in the pickup and drives to the next charging, where he exchanges the four empty packs for new, charges ones and, with a simple tap, logs them into his service group’s stock. The depot offers Clean Energy Packs with green electricity from the local solar park; the operator has thousands of Clean Energy Packs of various manufacturers, performance, and pricing in circulation all over Europe. On the way back, Jonas returns the four Clean Energy Packs to the local hardware store, which is on the way. The billing of the Clean Energy Pack rental and electric power is done automatically through the Battery-as-a-Service contract with the local solar pork company.
The holidays are just around the corner – the boss has already arranged to return the Clean Energy Packs to the local utility company for the time; a residual amount is agreed in the BaaS contract, which the utility company requires to balance the electricity grid. Jonas puts the Clean Energy Packs back into the charging cabinet, taps them with his mobile phone and starts their charging with clean, local energy.
