The federal government is planning to build up to 20 GW of new gas power plants to cover dark spots and supply gaps. But this strategy falls short. Modern storage technologies have long offered a more economical, climate-friendly and flexible alternative.

With the steadily growing share of renewable energy in the German power grid, the challenge of storage is moving into focus. Battery storage systems show that the future of energy supply is not only turning green — it is also becoming big.

The storage industry is very concerned about AGnES — the major reform of the network charging system by the Federal Network Agency (BNetzA). The discussion also focuses on the question of what network benefits large battery storage systems have in a commercial mode of operation.
