Zimbabwe platinum mines to ride out power cuts, gold output less secure

Power imports are cushioning platinum mining companies against Zimbabwe's worst blackouts in three years, but gold mines could face production cuts as they continue to rely on an unstable national grid, industry officials said. State utility ZETDC this week started indefinite rolling power cuts lasting up to ten hours per day, blaming low water levels at the dam that supplies the biggest hydro plant and creaking infrastructure at ageing coal-fired generators.

Swedish Foreign Minister outlines goal to be 100% reliant on renewables

The Nordic countries have brought their renewable energy expertise to South Africa for African Utility Week and shown how serious they are about reducing carbon emissions.

Release of updated IRP imminent, says Radebe, as he allays coal producers' fears

Energy Minister Jeff Radebe has promised that the update of the Integrated Resource Plan, which reflects the government’s policy blueprint for the power sector, will be concluded "very shortly". He told delegates attending the African Utility Week and PowerGEN Africa forum, in Cape Town, on Tuesday, that the government was still in the process of engaging with its social partners at the National Economic Development and Labour Council, but emphasised that the update was imminent. “Cabinet's approval of the IRP for South Africa will define a tangible plan for energy security that also enables the participation of independent power producers side by side with Eskom and municipalities,” said Radebe. He also pointed out that there was a room for coal-fired power in the future, but placed an emphasis on the need for clean coal technologies.

CER urges Ramaphosa to appoint environment-focussed Cabinet

In anticipation of next week’s Cabinet announcement, law clinic the Centre for Environmental Rights has requested that President Cyril Ramaphosa make environmental governance a priority and appoint committed Ministers to lead institutional reform. The CER has written to Ramaphosa with recommendations for the Presidency to create a Climate Change portfolio and a new Department of Energy and Climate, and has also advised that the Department of Water and Sanitation not merge with another department. With climate change severely threatening the planet, the CER wants the new Cabinet to prioritise climate considerations across all spheres of government and to be proactive in dealing with the threat, which the CER says the government has done very little to address, thus far.

Release of IRP 'imminent' – Energy Minister

South Africa's Integrated Resource Plan, which will set out South Africa's future energy mix, would be "concluded imminently", Energy Minister Jeff Radebe said on Tuesday. Speaking at African Utility Week taking place at the Cape Town International Convention Centre, Radebe said the IRP was still the subject of engagement with government's social partners at the National Economic Development and Labour Council. "Cabinet approval for the IRP for South Africa will define a tangible plan for energy security that also enables the participation of independent power producers side by side with Eskom," Radebe told delegates.

Global energy investment out of step with security of supply, climate needs

A new report on global energy investment in 2018 points to an ongoing misalignment between approved expenditure on new fuel and power projects and meeting the twin goals security of supply and decarbonisation. The International Energy Agency’s (IEA’s) ‘World Energy Investment 2019’ report, released on Tuesday, states that global energy investment stabilised at $1.8-trillion in 2018, following three consecutive years of decline.

Zimbabwe starts rolling power cuts, hitting mines, industry

Zimbabwe has started rolling power cuts lasting up to eight hours that will also hit mines, a schedule from the State power utility showed on Monday, after reduced output at both the largest hydropower plant and ageing coal-fired generators. The power cuts will add to mounting public anger against President Emmerson Mnangagwa’s government as Zimbabweans grapple with an economic crisis that has seen shortages of US dollars, fuel, food and medicines, as well as soaring inflation that is eroding earnings and savings.

Zimbabwe starts load-shedding as drought hits Kariba Dam power station

Zimbabwe started implementing load-shedding on Monday, after the government announced it was facing critical power shortfalls and had to introduce rotational power cuts in order to "balance the power supply available and the demand". Power utility supplier the Zimbabwe Electricity Transmission & Distribution Company last week said it had been forced to cut power generation at its Kariba Dam power plant due to low water levels. The dam, on the border of Zimbabwe and Zambia, is only 34% full and cannot generate electricity at optimal capacity.

South Africa’s energy transition won’t be ‘just’ in absence of inclusive social dialogue

South African Federation of Trade Unions general-secretary Zwelinzima Vavi has called for urgent social dialogue on South Africa’s “inevitable” energy transition from coal to renewable energy, warning that the country’s current framework will fail to deliver a just outcome for workers and poor communities. Speaking at a seminar in Johannesburg convened under the theme ‘Unlocking a Just Energy Transition for South Africa’, Vavi said not a single union failed to recognise that there would be a shift away from a carbon-based economy.

Eberhard calls for renewables to play a far greater role in South Africa

Energy expert Anton Eberhard has called for renewable energy to play a far greater role in South Africa, adding that solar and wind energy had saved the country from what could have been a far darker place during the recent spate of load-shedding. “Independent power producers have mitigated load-shedding. If we didn't have wind and solar, we wouldn't have had Stage 4 . . . we would have had Stage 5 and 6 [load-shedding]. South Africa would have been in darkness, so renewables are already proving their economic worth.”

Energy dept launches updated Wind Atlas for South Africa

Department of Energy (DoE) acting director-general has launched the Wind Atlas for South Africa (WASA) High-Resolution Wind Resource Map, which has expanded its coverage to all nine provinces of the  country.   Addressing delegates at a seminar in East London, the acting director-general emphasised the importance of accurately determining the availability of wind resources.   “As we continue on our ambitious renewable energy path, wind energy remains an integral part of this goal. However, it ...

Sand mining 'mafias' destroying environment, livelihoods – UN

Sand mining is eroding the world's river deltas and coastlines, damaging the environment and hurting livelihoods from Cambodia to Colombia, as government regulation fails to keep pace with rising demand, the United Nations warned on Tuesday. Global demand for sand and gravel, used extensively in construction, is about 50-billion tonnes or an average of 18 kg (40 lb) per person per day, according to a report published by the UN Environment Programme (UNEP).

IEA says world cannot ‘press pause’ on renewables, as capacity growth stalls

The International Energy Agency has expressed concern over the “unexpected flattening” of renewable-energy capacity additions in 2018, which, at 180 GW, remained in line with additions recorded in 2017. It was the first time since 2001 that year-on-year additions of renewable energy failed to grow and coincided with a 1.7% rise in greenhouse-gas emissions to an historic high of 33 gigatonnes. The IEA said in a statement that the 2018 renewables additions represented only 60% of the 300 GW in net new additions needed yearly to 2030 to meet the long-term climate goals outlined in the Paris Climate Agreement.

SABS hosts wind energy technical meeting

The South African Bureau of Standards (SABS) is hosting 40 international delegates of the International Electrotechnical Commission’s (IEC’s) technical committee 88 (TC 88) at the SABS’s plenary meeting on May 6 and 7. The IEC’s Renewable Energy Conformity Assessment will then meet on May 9 and 10 at the Groenkloof campus, in Pretoria.

Agri SA says concerned by Nersa’s reluctance to register small-scale embedded generator projects

Agricultural industry association Agri SA said on Monday it was concerned about what it called the National Energy Regulator of South Africa's (Nersa) reluctance to register small-scale embedded generator (SSEG) projects.  In a statement, Agri SA said its members had the potential to supply the electricity needed to prevent future rolling blackouts, known as load shedding,  through small-scale solar photovoltaic installations.
