The renewable energy from South Africa’s first wind and solar projects last year delivered R800-million more in financial benefits for the country than it cost, according to a study by the Council for Scientific and Industrial Research (CSIR).
The study was based on actual hourly production data for the different supply categories of the South African power system, including coal, diesel, wind and solar photovoltaic (PV).
The study found that diesel and coal fuel cost savings were R3.7-billion, owing to the generation of 2.2 TWh of wind and solar energy, which replaced the electricity that would have been generated from diesel and coal – 1.07 TWh from diesel-fired open-cycled gas turbines and 1.12 TWh from coal power stations.
Further, the CSIR determined that the economy saved R1.6-billion as a result of the 120 hours of “so-called unserved energy” that was avoided owing to the power generated by wind and solar projects.
