Various forms of energy storage will become an increasingly important part of the power system as the share of wind and solar power rises. Storage can use a variety of different technologies and employ both utility-scale and small-scale solutions.

Given that solar and wind power are dependent on weather conditions to generate electricity, their production can vary over time. Energy storage makes it possible to store surplus energy that is generated during periods of high production and use this energy when production is lower, or when demand exceeds generation. By realizing energy storage systems, Eolus can ensure that energy from wind and solar can be stored and used efficiently when needed, which contributes to a more reliable and sustainable energy future. This also makes it possible to reduce fossil-fuel use and support the transition to an efficient and renewable energy based future.
