Photovoltaic facilities and battery storage at the Hambach opencast mine, North Rhine-Westphalia

On the shoreline of the planned Hambach opencast mining lake, RWE has realised three 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 19,000 households with green electricity. RWE operates all three solar farms together with Neuland Hambach GmbH, the inter-municipal interest group representing 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. In addition, RWE has begun construction of a further solar power plant in the southern part of the Hambach opencast mine. Once completed at the end of 2026, the “Manheimer Bucht” solar park will generate enough electricity to supply around 5,000 households per year with climate-friendly power. A battery storage facility is also due to be built alongside the solar park from this summer onwards.

“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.

“RWE Neuland 3 Solar Farm” – a ground-mounted photovoltaic plant

The “RWE Neuland 3 Solar Farm”, with a capacity of 14 megawatts peak (12 MWac), is located near the village of Niederzier. Spanning around 12 hectares on the western edge of the Hambach opencast mine, over 22,000 solar panels can now generate enough green electricity to supply around 4,500 households per year in a climate-friendly manner. The photovoltaic plant was commissioned in August 2025.

“Manheimer Bucht” ground-mounted solar farm & battery storage

The “Manheimer Bucht” solar park is being built within the Hambach opencast mine, in the municipality of Kolpingstadt Kerpen. A total of 25,300 solar modules are being installed in an area the size of around 20 football pitches. Upon completion at the end of 2026, the solar farm will have a capacity of 16.5 megawatts peak (14.8 MWac) and will produce enough climate-friendly electricity to supply the equivalent of around 5,000 households annually.

“Manheimer Bucht” will form the southern end of the future lake at Hambach opencast mine. It will take several decades for the water to reach the area. RWE is using this time to expand renewable energies in suitable, approved areas.

The solar farm will be supplemented by a co-located battery storage facility, construction of which is scheduled to begin this summer. Designed to have a capacity of 80 megawatt-hours, the storage-facility is planned to be commissioned end of 2026 to contribute to grid stability.

As part of the cooperation between RWE and NEULAND HAMBACH GmbH, the municipalities also have the option to participate in the “Manheimer Bucht” project.

Status: Under construction
