Salzgitter Flachstahl, the strip-making subsidiary of Salzgitter AG, and Zelestra have signed what they say is Germany’s largest hybrid solar-plus-storage power supply agreement (PPA).
The long-term agreement covers two projects that support the production of green steel and increase grid flexibility, Kallanish learns from the steelmaker.
As part of the agreement, Zelestra will build, own and operate two new hybrid plants, each with directly connected battery storage systems, in Brandenburg and Thuringia. Salzgitter will purchase a total of 147 MW or 158 GWh/year of solar power from both plants and control the operation of the battery storage systems.
According to Salzgtter, the agreement is the first hybrid PPA in the German market for both partners, and makes Salzgitter the operator of a battery storage system for the first time.
For Salzgitter Flachstahl, hybrid PPAs are an important building block in meeting increasing demand for green electricity for the transformation of steel production within its SALCOS project, it says.
With Germany a core market for Zelestra, the company is now advancing more than 2 GW of solar, hybrid, wind and storage projects in the country, Salzgitter says.
