“The project has the potential to set new standards for the entire industry, with state-of-the-art solar power plants being built on a former mining site, generating sustainable electricity and creating economic value. This revitalises unutilised land and contributes to the sustainable energy transition of German industry. We are proud to be a partner in this innovative project,” says Dr Jan Wicke, Chief Financial Officer of Talanx AG.

Construction of the solar power plant began in spring 2026. The facility is located at a former quarry belonging to a cement plant in the Misburg district of Hanover and has a capacity of approximately 25 MWp. The plant’s capacity is equivalent to the energy consumption of approximately 7,200 households, helping to reduce around 18,700 tonnes of CO2 emissions. Around 60 per cent of the renewable electricity will be supplied directly to the Heidelberg Materials production plant via a long-term direct supply agreement. Further projects at other Heidelberg Materials sites across Germany are already in the planning stage.

The project is being implemented in partnership with Heidelberg Materials, one of the world’s largest building materials companies, and WI Energy, a specialist provider of large-scale photovoltaic systems which will take on the long-term operational management of the planned projects. The Talanx Group’s investment is being made through Ampega Asset Management, a subsidiary of Talanx AG based in Cologne.

“This project makes a significant contribution to the realisation of our ESG ambitions together with supporting Heidelberg Materials in reducing its carbon footprint through sustainable on-site electricity generation,” says Dr Thomas Mann, CEO of Ampega. “In addition to existing grid connections and high scalability, the project also offers the opportunity to integrate other technologies, such as battery storage, into the wider investment strategy.”
