Saudi Arabian developer ACWA Power has signed an investment agreement with the state-owned Central Energy Fund of South Africa to build the 100MW Redstone solar thermal power plant in Northern Cape province.

The partnership establishes the framework for both players to co-invest in renewable energy projects, the first of which will be Redstone.

The 100MW solar project, developed as part of the Renewable Energy Independent Power Producers Programme (REIPPPP) of the Department of Energy, is due to start construction later this year.
