A list compiled by a British price comparison website draws upon data from German company Statista which shows clean energy – including hydro – made up 12.74% of the nation’s power mix at the end of September.

French thinktank the Institut Montaigne says Africa is absent from the global solar revolution for several reasons including a lack of suitable financing tools, the small size of projects and a systematic recourse to tendering. Removing artificial price signals set by ever more competitive tenders could be a step towards a more mature market, ready for large scale solar tenders.

Battery innovations started to come thick and fast this quarter as the hunt for alternatives to lithium-ion intensified and the latest slew of solar tenders indicated the relentless pressure on solar power generation costs was showing no sign of abating.

The nation has been plagued by extensive power outages again with debt-riddled utility Eskom blaming heavy summer floods for taking out extensive parts of its coal-fired power generation fleet.

The South African utility has issued a 20-strong tender for 50 kW solar inverters and mounting structures, to be used in four power plants. Although it is unclear whether the tender marks the energy company’s first step into solar energy, the procurement follows the recent publication of South Africa’s Integrated Resource Plan. Eskom is reportedly developing a renewables-linked large scale storage project which may explain the need for inverters.

With power production up 133% year-on-year, revenues and EBITDA also rose significantly.

That would take the country to 8.28 GW of generation capacity by the end of the next decade with the government stating up to 6 GW of small scale capacity could be required on top. By that stage, however, coal would still amount to 43% of generation capacity and gas and diesel a combined 8.1%, under the new Integrated Resource Plan.

The building-sized trucks run on diesel and prompt logistical complications as large amounts of diesel must be shipped to remote mining sites. Attempts to decarbonize the mining sector will have to consider the heavy-duty vehicles.

Power purchase agreements may be voluntarily renegotiated by extending the 20-year deals or enabling independent power producers to add more efficient PV components, thus increasing plant generation capacity.

A team of researchers modeled the country’s energy future, finding that the drought plagued municipalities could benefit massively from large scale renewables deployment. The current reliance on coal-fired power stations causes immense water consumption, worsening the problem.
