Germany is to grow its large electricity battery capacity threefold to 200 MW from 60 MW this year according to Team Consult advisory.

With the country’s grid infrastructure not developed sufficiently to capitalise on its remarkable green energy growth, storage is being seen as vital in supplying super fast balancing services, ensuring the overall system runs efficiently.
Big energy storage
Battery storage is a significant new development in the transformation of the power sector as it will eventually allow harnessing of fluctuating wind and solar power for use by transport grids, solar-producing householders, and the car industry.

“We observe a rising trend for storage batteries to be used to stabilize grids,” said author Christoph Hankeln.

Through the batteries, grids will receive short-term boosts to cope with varying green power output.

Team Consult estimates that this market has a 800 MW capacity, meaning batteries could account for 25 per cent by the end of this year, displacing some of the currently active thermal energy plants.

An example is coal-to-power group Steag, which in a $106.32m project is due to complete the installation of six 15 MW batteries at German coal plant sites this year.

Britain’s National Grid last August awarded four-year contracts to battery operators worth a total of £66m.
