Lanxess and Evonik have separately signed power purchase agreements (PPAs) with energy companies Engie and EnBW respectively, under which they will increase the renewable share of their electricity needs in the coming years. The former’s PPA will see 1,400 GWh supplied to seven sites from 17 wind farms and four solar parks in Germany. Meanwhile the latter is taking an additional 50 MW from EnBW’s planned He Dreiht offshore wind farm in the North Sea over the next 15 years, in addition to 100 MW it signed to take last November.
