RWE installs megabattery project

• The 117MW project is set to begin commercial operations in the following few days

RWE has actually ended up installing a megabattery project at 2 of its power plants.

Work on the 117MW/128MWh battery system was completed in 14 months, with an overall of 420 blocks of lithium-ion batteries installed at RWE power plant sites in Lingen (Lower Saxony, 49MWh) and also Werne (North Rhine-Westphalia,79 MWh).

The new system is capable of providing the specified power for around a hr.

The system has a virtual connection with RWE's run-of-river power plants along the Moselle River. By precisely managing the flow rate at these plants, RWE can provide extra power as balancing power.

As a result, the complete ability of power available for grid stabilisation in this system enhances by approximately 15%.

The battery storage system has currently fed power into the grid and is presently undergoing a dry run. Commercial operation is arranged to begin in the next few days.

The firm has spent around EUR50m right into the megabattery project.

Roger Miesen, Chief Executive Officer of RWE Generation, said: "With the enhancing expansion of renewable resources, Germany needs ingenious storage space services on an industrial scale that can step in when the wind and also sun are not providing.

" In terms of size and technology, we are establishing benchmarks in this nation with our mega-battery. The finished battery storage space facilities as well as our hydroelectric power plants on the Moselle will function hand in hand in the future to aid secure the power grid."
