On the shoreline of the planned Hambach opencast mining lake, RWE has realised two photovoltaic plants, one of which has an integrated battery storage system. Until the lake has reached its final filling level, there will be many years of temporary use of the site for the two large solar parks. In total, the RWE Neuland solar parks can supply 14,500 households with green electricity. RWE operates the solar parks together with the Neuland Hambach GmbH, the inter-municipal organisation representing the interests of the neighbouring municipalities of Elsdorf, Jülich, Kerpen, Merzenich, Niederzier and Titz. This organisation plays a key role in coordinating and shaping the structural change around the Hambach open-cast mine.

“RWE Neuland Solar Farm” photovoltaic plant with integrated battery storage

The solar plant provides 12 MW of electricity at its peak. The connected battery storage is configured for a two-hour charging and supply cycle of 4.1 MW. It thus acts as a buffer between solar power generation and the grid, enabling power feed-in to be even better matched to demand. 

Status: In operation

Hambach Niederzier Solar Farm

RWE has started construction of a new photovoltaic plant near the village of Niederzier. More than 22,000 solar modules are being installed on a 12-hectare area on the western edge of the Hambach open-cast mine. Combined, they will generate enough electricity to supply around 4,500 households in a climate-friendly way. The new photovoltaic plant is scheduled to be commissioned in September 2025. It will then have an output of 13.9 megawatts peak (12 MW AC).

Status: Under construction
