Battery storage systems

We store more – for a secure power supply in a world of renewables

Link between renewables and stable electricity grid

Battery storage systems are a key element in the energy transition, since they can store excess renewable energy and make it available when it is needed most.

As a battery storage pioneer, RWE develops, builds and operates innovative and competitive large battery storage systems as well as onshore and solar-hybrid projects in Europe, Australia and the US.

When it comes to linking battery storage technology with green electricity production, RWE can draw on many years of experience in the energy storage and renewables sector. The company provides project planning, modelling, system integration, and commissioning of the projects in house and under one roof.

Battery storage systems as all-rounders

Battery storage technology is mature and competitive. It can be adapted to suit almost any conditions. Battery storage systems can be erected nearly anywhere with very short lead-in and construction times. They can be small and compact or come in XXL sizes to suit industrial applications.

Highly efficient modern batteries play in the top league of storage technologies – the stored energy can be made available again at any time with extremely minimal losses.

Another advantage is their ability to store electricity and feed it back into the grid with lead times counted in fractions of seconds. Thanks to smart IT solutions, battery storage systems can automatically rectify imbalances between electricity production and demand.
