Innovative Energy Transition Hub

RWE plans to build huge battery storage facility in Dilsen-Stokkem

The energy sector is developing rapidly. In order to become climate-neutral by 2040, RWE is shifting up a gear with its Growing Green investment programme to a more sustainable and flexible production portfolio. The focus is even more on sustainable energy production with sun and wind, but also energy storage (e.g. with batteries) and the production of green hydrogen. This has led RWE to build an Innovative Energy Transition Hub in Dilsen-Stokkem by developing a large-scale battery storage facility.

The plan to build a gas-fired power plant is immediately and completely halted. RWE also withdraws its appeal against the refusal of the environmental permit for the gas plant.

Not energy production but energy storage

RWE wants to build and operate a large-scale lithium-ion battery storage facility on its site at Energielaan 1 in Dilsen-Stokkem (Belgium). The facility will have a total installed capacity of 200 MW (megawatt) and an energy volume of 800 MWh (megawatt hours). This means that the system, once fully charged, can provide 200 MW of power over a four-hour period.

Compared to other flexible power plants, such as gas power plants, a battery storage facility does not produce its own electricity and does not emit CO2 (carbon dioxide) or NOx (nitrogen oxides). It merely acts as a temporary storage of electricity that can later be fed back into the grid. RWE's battery facility will therefore serves to compensate for impending shortages in the electricity supply with electricity previously stored at times of surplus.

Roger Miesen, Chief Executive Officer and Chief Operating Officer of RWE Generation SE

"The Innovative Energy Transition Hub in Dilsen-Stokkem will help facilitate RWE's further growth ambitions in renewable energy production in Belgium and ensure better system integration of such green production technologies.

Dilsen-Stokkem would thus become one of the largest battery storage facilities in Europe. The facility is literally one of the suggestions that came up in the survey of the neighborhood in the context of the earlier application to build a gas power plant. RWE has taken this suggestion to heart and has quietly developed it further."
