Battery energy storage systems

Battery storage completes the flexibility portfolio

The energy transition demands flexibility solutions, such as high-performance battery energy storage systems (BESS). These systems can be utilised with great versatility to stabilise the grid. BESS swiftly balance fluctuations in the electricity grid and stabilise grid frequency. They ensure security of supply while seamlessly integrating electricity production from wind and solar energy into the energy system. As efficient pioneers, they drive the further expansion of renewable energies. 

As part of its strategy, Alpiq is reinforcing its position as a provider of flexibility in its core markets. Alpiq is progressively expanding its highly flexible power plant portfolio with the addition of battery energy storage systems.
