About the project

Project Sapphire (400 MW / 1,600 MWh) will provide critical storage capacity where renewable generation meets heavy industry. Located near Schwedt’s refinery and cross-border grid flows, it helps secure reliable, clean electricity for households and industry alike. Developed in partnership with the city of Schwedt/Oder, the municipality of Vierraden, and local stakeholders, Sapphire strengthens regional resilience and supports Brandenburg’s energy future.
