- Key drivers and restraints
- Regional trends
- The impact of the commodity price increase on the battery prices
The project was announced in 2019 and will be commissioned in 2025.
Description
The key application of the project is grid supportive services.
Additional information
The project is a part of German grid operators plan to reduce redispatch costs. German power grid operators plan to trial massive batteries as grid boosters at vulnerable locations to reduce redispatch costs and defer new cable investment. TransnetBW GmbH, one of four German transmission system operators, is planning a 250 MW battery at Kupferzell.
Methodology
All publicly-announced energy storage projects included in this analysis are drawn from GlobalData’s Power IC. The information regarding the projects are sourced through secondary information sources such as country specific power players, company news and reports, statistical organisations, regulatory body, government planning reports and their publications and is further validated through primary from various stakeholders such as power utility companies, consultants, energy associations of respective countries, government bodies and professionals from leading players in the power sector.
