German energy giant RWE develops a new giant battery storage system which is 128MWh in Total
Innovative battery storage solutions are an important component of Germany’s energy transformation.
In March, RWE jointly established a giant battery storage system with a total output of 128 MWh in Lingen (Lower Saxony) and Werne (North Rhine Westphalia), which includes 420 lithium ion battery modules to help stabilize the power grid.
RWE (German Rhine Group) was founded in 1898 and headquartered in Essen, Germany. It is the largest energy company in Germany and one of the three largest energy companies in Europe. Over 100 years of operation, the company’s business has covered the entire energy industry chain, including mining and power generation, energy planning, environmental consulting, engineering design, asset optimization, environmental protection services, energy trading, etc.
As of March 15 this year, RWE’s ongoing battery storage project has an installed capacity of approximately 280 MWh. Currently, it is planning to implement a global battery storage project with a capacity of more than 1.7 GWh, with the goal of establishing three 3GWh (totaling 9 GWh) battery storage systems worldwide by 2030.
“With the increasing expansion of renewable energy, Germany needs innovative industrial scale storage solutions to assist wind and solar energy in achieving better utility in Germany.” Roger Miesen, CEO of RWE, welcomed the project. “In terms of size and technology, our giant battery system has also set a standard in Germany.”
RWE’s new battery storage system is combined with radial flow power plants to provide additional energy capacity by selectively increasing or decreasing the flow of hydropower plants (an increase of 15%). According to RWE, the investment amount for giant batteries is about 50 million euros. The completed battery energy storage system and hydropower stations will work together to stabilize the power grid system in the future.
