Utility-scale Battery Storage Systems

Energy storage will make an important contribution to the stability of future power grids which have a significant share of renewable energy. It will become more important as the renewable energy share will get larger in the future energy mix.

The main areas of application of a storage unit are: Permanent frequency regulation, peak-shaving at high load or high feed-in periods, allocation of regulation energy for national grid operators as well as continual energy provision for off-grid applications. The BELECTRIC LION EBU (Energy Buffer Unit) is optimized for these applications and is designed for maximal scalability and flexibility. It can be adapted for today’s and tomorrow’s needs at local or national power grids, guaranteeing a stable grid, and even allowing more renewable energy in the near future.


Sustainable, safe and fast as lightning. The BELECTRIC EBU  delivers 1300 kW of power to your grid within a fraction of a second.
