Battery storage

upgrades for solar power plants

Increase the profitability of your solar power plant

The energy market is changing constantly. The existing power network infrastructure is not prepared for decentralised and volatile power generation through renewable energies, and regularly reaches its limits. In order to be prepared for future market changes, BELECTRIC is expanding existing plants with large-scale battery storage technology now.

BELECTRIC has been selling battery storage primarily as a decentralised unit for stabilising electricity grids since 2012. BELECTRIC is now also opening up this market for solar power plant operators and has developed a storage upgrade that can be used to equip all existing and newly built plants. In addition to trading in classic solar power, plant operators also sell the stored energy as instantly available balancing power for example, at attractive prices.
