Current developments in the field of commercial power storage

Commercial power storage technology has reached a remarkable level of maturity over the last two years, making its use not only economically viable but even indispensable.

• Power storage systems are becoming increasingly efficient.

• The costs of electricity storage are continuously declining. (The acquisition costs per kilowatt hour have fallen by over 60% in the last three years.)

• This improves the benefit-cost ratio of electricity storage.

At the same time...

• The demand for electricity in Germany is continuously increasing.

• Energy policy and energy prices are unpredictable: Nuclear power plants are being shut down, coal as an energy source is politically controversial, and there is a risk of uncertain dependence on Russian energy sources. The expansion of the power grid is stalling.

• This makes decentralized energy solutions more attractive.

This is reflected in the brisk activity and the electricity prices offered in the balancing energy market. This is especially true for owners of PV systems: The feed-in tariff is continuously decreasing, increasing the importance and value of self-consumption.

In fact, developments in the field of energy storage make the construction of PV systems even more advantageous than ever before, both in terms of technological development and the price development of components.
