Statkraft inks 300 GWh RE PPA with German cement mfr

Statkraft, a hydropower company fully owned by the Norwegian state, has signed a further power purchase agreement (PPA) with OPTERRA, a German cement manufacturer, for the supply of renewable power from onshore wind and solar power.

It follows a wind power PPA agreed in 2021 and enables OPTERRA to further transition its plant operations to a renewable energy supply, an official statement said.

Under the agreement, OPTERRA, will receive an additional 300 gigawatt hours (GWh) of renewable power supplied by Statkraft to its plants in Karsdorf (Saxony-Anhalt) and Wössingen (Baden-Württemberg).

From April 2022 to June 2023, 15 GWh of wind power will be provided; and from July 2023 to December 2032, approx. 30 GWh of solar power will be supplied annually.

“Having concluded the first wind power PPA at the end of 2021, OPTERRA has sought additional green power volumes for a long-term period. Thanks to our diversified portfolio, we can combine electricity supplies from wind farms available at short notice with long-term electricity supplies from new solar plants. Thus, OPTERRA receives exactly the PPA concept that meets its needs,” says Patrick Koch, Head of Origination for Statkraft in Germany.

“Renewable power PPAs are still relatively new in some German industries. As an experienced and reliable partner, we are very pleased to be able to demonstrate how such PPAs help energy-intensive companies like OPTERRA to reduce CO2 emissions.”

“The second PPA is another step forward on our roadmap for reducing CO2 emissions. Initiatives like these demonstrate our ongoing sustainability commitments and contribute to achieving OPTERRA’s ambitious sustainability goals,” says Danilo Buscaglia, CEO of OPTERRA.

In December last year, Statkraft and OPTERRA concluded a renewable power PPA with a term of four years (2022 to 2025) and a total supply volume of 120 GWh of wind power. With the additional annual delivery of approx. 30 GWh of renewable power, which corresponds to the yearly consumption of around 7,500 four-person households, OPTERRA hopes to be able to cover up to 20% of the Karsdorf and Wössingen cement plants’ annual electricity demand.

The wind power is generated in wind farms that no longer receive EEG subsidies. The PPA thus enables the continued operation of these wind farms. The solar power is supplied from Statkraft’s solar portfolio and thus directly supports the growth of renewable energy in Germany, said the company.
