Covestro to purchase solar power for producing mass-balanced plastics
Source:Adsale Plastics Network    Editor:JK    Date:22.Dec.2021

Covestro and energy provider EnBW have signed a long-term corporate power purchase agreement (PPA) for solar-generated electricity. Under the agreement, Covestro has secured 63 megawatts (MW) of capacity from EnBW’s 187 MW “Weesow-Willmersdorf” solar farm in Brandenburg, Germany.


The EnBW-operated solar array is the biggest of its kind in Germany and has been implemented without any subsidy under the German Renewable Energy Sources Act. This agreement with Covestro is the first PPA for the project.


The solar power will be deployed at the german Covestro sites in Dormagen and Krefeld-Uerdingen for 15 years from the beginning of 2022. The company will use the renewable energy there primarily for the production of more sustainable, mass-balanced plastics manufactured in a so-called drop-in process using alternative raw materials. These include mass-balanced polycarbonates and mass-balanced thermoplastic polyurethanes.


The EnBW solar farm "Weesow-Willmersdorf" in Brandenburg is the biggest of its kind in Germany with its total of 465,000 solar panels.

“By sourcing solar power from EnBW’s farm, we are underlining our ambition to play a pioneering role on the road to a climate-neutral future and once again sending out a signal for the expansion of renewable energies in Germany,” said Dr. Klaus Schäfer, Chief Technology Officer at Covestro.


EnBW’s solar farm near Berlin with its 465,000 solar panels has been fully connected to the grid since March 2021. “PPAs are an important tool for making subsidy-free generating assets commercially viable. They are also pivotal to the energy transition, as they help industrial consumers achieve their climate targets quickly and efficiently,” added Dr. Georg Stamatelopoulos, Chief Operating Officer Generation & Trading at EnBW.


Covestro intends to primarily use the solar power from EnBW in the production of mass-balanced and ISCC Plus-certified high-performance plastics of the Makrolon RE and Desmopan product series at its sites in Dormagen and Krefeld-Uerdingen.


Covestro is already able to produce selected grades of Makrolon RE polycarbonate that are climate-neutral from cradle to factory gate. It also produces Desmopan thermoplastic polyurethane with an improved carbon footprint. Polycarbonates are used in electronics products and car headlights, among other things. Thermoplastic polyurethanes are used, for example, in household products, ski boots and industrial applications.
