The installed storage capacity opens up new possibilities for Fill in terms of self-sufficiency: On weekends, the entire company is powered by surplus PV electricity – without drawing power from the public grid. On average workdays, the storage system bridges the night hours and ensures that the solar power generated during the day is used optimally.
“Our goal is to charge all excess power from our PV systems into the storage units and feed it back to our consumers as needed,” explains Günter Redhammer, COO of Fill. A key advantage: Until now, the PV systems had to be partially taken off the grid on particularly sunny days – especially on weekends. “The reason for this was highly fluctuating electricity prices, which can even drop into negative territory when grid utilization is high. In such cases, we would have had to pay to feed PV electricity into the grid,” adds Redhammer. The Battery Park provides an economically and energetically sensible alternative here.
Optimal utilization thanks to AI-supported control
Even during the winter months, when the PV electricity production is lower, the storage system offers significant advantages. AI-supported control software continuously optimizes self-supply. The system intelligently decides whether to charge the storage system from PV systems or – when prices are low enough – from the grid. At the same time, the facility actively helps relieve the strain on the power grid, as the storage system cushions consumption peaks from production.
Strong partnerships for a forward-looking project
The project was planned and implemented in close collaboration with long-standing partner companies hapec GmbH and EBG GmbH from Ried. Together, they realized a forward-looking solution that combines economic efficiency, sustainability, and security of supply.
