German magazine Capital reports that Hamburg-based energy company 1Komma5 Grad has secured up to €500 million in financing through a partnership with Deutsche Bank and Norddeutsche Landesbank, in a bid to expand renewable energy systems in public buildings across Germany.

The company said the funding could support the rollout of photovoltaic systems, battery storage and, where needed, electric vehicle wallboxes at roughly 10,000 buildings. Under the model, public institutions would not pay upfront for the equipment or installation. Instead, 1Komma5 Grad would install and operate the systems and enter fixed-term electricity supply contracts with the institutions.

The initiative targets a largely untapped segment of the energy transition in Germany’s public sector. 1Komma5 Grad, which sells solar, storage and heat pump systems and connects distributed power sources through its own energy management software, is positioning the project as a way to address budget constraints that have slowed adoption.

The company is already testing the approach in Lower Saxony, where it won a contract to install and operate solar systems on 550 state-owned buildings.
