EnBW and Bosch join forces on storage

Bosch and EnBW are jointly developing a power storage unit, which is being built at EnBW’s power plant in Heilbronn, Germany.

The technology is aimed at providing called primary control energy, or the capability to compensate for short-term fluctuations in the grid.

The duo have announced plans to work closely with battery solutions for the energy market and will establish a joint project company, which is responsible for the design, construction, connection and operation of the battery. The move is still subject to approval from antitrust authorities.

“The cooperation with EnBW is a further important step in establishing storage technology in the energy market and thus successfully shaping energy consumption,” said Cordelia Thielitz, Managing Director of Bosch Energy Storage Solutions.

The current storage in Heilbronn consists of 768 lithium-ion battery modules and has a maximum power output of around 5 MW with an installed storage capacity of five megawatt hours. Lithium-ion batteries can provide very short-term energy and are therefore ideally suited to provide primary control performance.

The storage unit accounts for just under a fifth of the control capacity of a large power station and can store or discharge it within seconds and accurately.

Bosch is responsible for the planning and realization of the battery system, EnBW is responsible for construction work and grid connection at the site.

In a separate development on Friday EnBW’s GKN I became the first nuclear power station in Baden-Wàƒ¼rttemberg to be granted permission to dismantle. In its current assessment, EnBW assumes that the dismantling of GKN I will take approximately 10-15 years. à‚
