PPAs don’t only offer advantages to companies. The Energiewende as a whole also benefits from long-term electricity procurement agreements – they are increasingly supporting the construction of power plants for green electricity. For example, EnBW already concluded the first long-term power purchase agreement in Germany in 2019 for a solar park constructed without the aid of subsidies. This agreement provided the basis for approving the financing of the project: EnBW is acting as an intermediary between the operator and electricity users, purchasing 100 percent of the green electricity generated at an 85 megawatt solar park located to the east of Rostock for a period of 15 years.
EnBW concluded a PPA in the Spanish region of Andalusia in 2021 with the solar park and wind farm operator Blue Elephant Energy AG (BEE) based in Hamburg, and will receive the green electricity from a 150 megawatt solar project over a period of ten years – enough electricity to cover the annual electricity demand of around 95,000 households. “With our long-standing experience on both the generating and trading side, we see good marketing opportunities in the Spanish wholesale market, as well as for customer-specific solutions,” explains EnBW Head of Trading Heydecker. “We believe that PPAs are the bridge between green electricity production and customers.”
In December 2021, EnBW also signed a PPA with the materials manufacturer Covestro. This means Covestro has secured 63 megawatts (MW) of the output from EnBW’s 187 MW “Weesow-Willmersdorf” solar park in Brandenburg. This power plant operated by EnBW is the largest solar park in Germany. It was also constructed without EEG funding from the government. Over the next 15 years, Covestro will primarily use the solar electricity for the production of sustainable plastics made of alternative raw materials at the Covestro sites in Dormagen and Krefeld-Uerdingen – and will thus move a step closer to achieving its target of becoming climate neutral by using renewable energies.
