ENGIE starts French solar-storage build while R.Power nears German solar completion
ENGIE began construction on its first French project pairing solar generation with battery storage, a 29.8 MWp array and 8.8 MW/20 MWh battery at a former quarry in Centre-Val de Loire. R.Power is finishing a 20 MWp solar farm in Saxony-Anhalt, Germany, expected to be connected before the end of November 2026. Madison Energy and Verogy completed a 7.2 MW solar facility for Beaver Water District in Arkansas, estimated to supply 15–20% of the utility's electricity needs.
ENGIE’s Buisson installation will place roughly 46,000 panels across about 23 hectares of a disused quarry near Saint-Jean-Froidmentel. The solar array and battery will use shared grid infrastructure, including an approximately 11-kilometre link to a substation, with grid connection planned for summer 2027 and commercial operation by December 2027.
R.Power’s Kloetze plant in Saxony-Anhalt is due to energise before late November 2026 and should produce about 20 GWh yearly. It holds a 20-year auction-backed support agreement, was financed with Deutsche Leasing Finance in January 2026, and is the company’s first large German PV development; it also reports about 115 MW of further auction contracts and a pipeline above 2 GW.
These projects could affect local residents, grid operators, and utility customers by adding renewable generation and storage near existing infrastructure. The French battery may help shift solar output toward higher-demand periods, while the German and Arkansas installations may support regional electricity needs and, for Beaver Water District, potentially lower long-term costs for a utility serving more than 425,000 customers. Benefits may depend on grid connections, construction timelines, and how storage is operated.
