The UK Foreign Secretary’s Special Representative for Climate Change, Sir David King, warned on Monday that countries building new coal-fired power stations could well be building “stranded assets”. Speaking in Johannesburg on Monday, Britain’s former Chief Scientific Adviser, who was born and educated in South Africa, said any country still building coal-fired power stations was building “white elephants”. Print Send to Friend 13 2 “These are stranded assets that won’t yield electricity in 50 years time, because you would have mothballed them in favour of clean, renewable energy coming through.” South Africa is currently building two new large-scale coal-fired power stations in the form of Medupi and Kusile and is about to embark on a programme to procure coal baseload capacity from independent power producers. It is also a major coal exporter.

The installation of rooftop photovoltaic panels is on the rise, but South Africa is not as solar-friendly as it could be.
Eskom may be unable to avert an energy crisis, but South African households and businesses can generate power on their rooftops at a cost per kilowatt that rivals that of megaprojects such as Medupi or Kusile, without subsidies or incentives.
The cost of rooftop solar photovoltaic systems to power residential and commercial buildings has dropped over recent years to reach parity with domestic and commercial tariffs.
According to the Council for Scientific and Industrial Research (CSIR), residential-sized photovoltaic systems are already a cost-competitive alternative to other new-build options, coming in at an estimated 81 cents a kilowatt hour (kWh) versus 80 cents at Medupi or Kusile. This solar power cost includes financing at an interest rate of 9%…
By 2030, South Africa’s new coal-powered stations Medupi and Kusile will be online and several nuclear power stations will feed into the grid. The country will have enough power and parents will tell their children stories about how they were conceived during something called “load shedding”.
During the 2008 energy crisis, the department of energy commissioned a plan for the next 20 years that would ensure the country had enough power. The document, called the Integrated Resource Plan (IRP) 2010, was written at a time of crisis and called for a doubling of the national grid to 85 000MW. The plan was also based on ambitious economic growth rates. Read more on MG Online
South Africa’s Department of Energy (DoE) has issued a formal appeal for companies and individuals to provide it with information on possible near-term solutions to reduce or shift electricity demand, as well as to immediately improve supply – the responses will guide the design of future procurement processes.
Government’s Independent Power Producer (IPP) Office released the request for information (RFI) in mid-December and responses need to be submitted by February 2.
The RFI documentation notes that demand response and/or distributed generation strategies are “critical” to improving the reserves needed by the system operator to better employ available generating capacity and to allow for higher levels of power-station maintenance. The anticipated daily shortfall, the RFI adds, is likely to be between 3 000 MW and 5 000 MW until additional generation capacity is introduced. Read more on Polity
GOVERNMENT has made “significant progress” in engaging with prospective nuclear vendor countries, the Presidency said on Wednesday.
Intergovernmental framework agreements had been signed with Russia, France, China, South Korea and the US, marking the “initiation of the preparatory stage for the procurement process”, Presidency spokesman Mac Maharaj said in a statement.
The government had now concluded a series of international vendor parades, which was “a significant milestone in the government pre-procurement phase for the roll out of the nuclear new build programme”. The government will now “design and launch a procurement process”, the Presidency said. Read more on BDLive
