Sustainable woodfibre products and solutions company Sappi’s Southern Africa business and energy trader Enpower Trading have reached financial close on a five-year 175 GWh/y renewable energy power purchase agreement (PPA). Under the terms of the PPA, which was first announced in May last year, Enpower will source power from green energy solutions provider SolarAfrica Energy’s 1 GW Sun Central 1 solar PV project, which is being built near De Aar, in the Northern Cape, and supply electricity to Sappi’s South African operations.
