Shell Energy Europe Ltd. said Sept. 7 it signed a 15-year power purchase agreement (PPA) for solar power from Witznitz Energy Park, the largest solar project being developed in Germany.

The PPA with asset owner HANSAINVEST Real Assets is for 600 megawatts (MW) of capacity, Shell said in a news release. The energy company said it will sell 323 MW to Microsoft Corp. as part of a separate agreement. Both companies are working toward net-zero ambitions. Microsoft has committed to a 100% supply of renewable energy by 2025, while Shell is targeting net-zero emissions by 2050.

“We are continuing to strengthen our low-carbon power portfolio,” Tom Summers, European vice president at Shell Energy Trading, said in the release. “Solar power purchase agreements enable us to combine our strengths in power trading and optimization with our existing customer relationships to deliver more value with less emissions.”

The solar project, being constructed by Move On Energy at the former site of a coal mine near Leipzig, is expected to start generating electricity by year-end 2023.
