South African truckers will go to court next week in a bid to get dozens of power deals with renewables projects cancelled, as the nation’s powerful coal lobby continues its campaign of opposition to its clean energy ambitions.

The Coal Transportation Forum (CTF) will ask the Guateng High Court to set aside power purchase agreements (PPAs) signed by state utility Eskom with more than 2GW of wind and solar projects under Round 4 of South Africa’s REIPPPP procurement programme, arguing they were concluded without following due process.
