Eskom is a South African electricity public utility, established in 1923 as the Electricity Supply Commission by the government of South Africa in terms of the Electricity Act . It was also known by its Afrikaans name Elektrisiteitsvoorsieningskommissie . The two acronyms were combined in 1986 and the company is now known as Eskom. Eskom represents South Africa in the Southern African Power Pool.The utility is the largest producer of electricity in Africa, is among the top seven utilities in the world in terms of generation capacity and among the top nine in terms of sales.Eskom tries to operate a number of notable but non functional power stations, including Kendal Power Station, and Koeberg nuclear power station in the Cape Province which is running at 50%, the only nuclear power plant in Africa. The company is divided into Generation, Transmission and Distribution divisions and together Eskom generates approximately 95% of electricity used in South Africa.Due to the South African governments attempted privatisation of Eskom in the late 1990s, Eskom's requests for budget to build new stations were denied. President Thabo Mbeki said in December 2007 that this was an error, and it is now adversely affecting the South African economy.In January 2008 Eskom introduced "load shedding", planned rolling blackouts based on a rotating schedule, in periods where short supply threatens the integrity of the grid. Demand-side management has focused on encouraging consumers to conserve power during peak periods in order to reduce the incidence of load shedding. Wikipedia.

OCTAVIUS aims to demonstrate integrated concepts for zero emission power plants covering all the components needed for power generation as well as CO2 capture and compression. Operability and flexibility of first generation post combustion processes are demonstrated by TNO, EnBW and ENEL pilot plants in order to prepare full scale demo projects such as the ROAD and Porto Tolle projects that will start in 2015. OCTAVIUS will establish detailed guidelines with relevant data on emissions, HSE, and other operability, flexibility and cost aspects. In addition, OCTAVIUS includes the demonstration of the DMX process on the ENEL pilot plant in Brindisi. This second generation capture process can enable a substantial reduction of the energy penalty and operational cost. The demonstration is an essential step before the first full scale demonstration envisaged to be launched at the end of OCTAVIUS. Application to coal power stations but also NGCC will be considered. OCTAVIUS builds forward on previous FP6 and FP7 CCS projects such as CASTOR and CESAR. The main coordinating research institutes and industrial partners of these projects also take part in OCTAVIUS. Results of the clean coal research are provided by end-users, engineering companies and technology vendors partnering in OCTAVIUS. Each of the demo sub-projects (SP2 and SP3) is led by a power company. The demo sub-projects are supported by work packages in SP1 dealing with RTD support activities and common issues. Two work packages in SP0 are dedicated to management and dissemination actions respectively. The latter work package includes contacting stakeholders outside OCTAVIUS. OCTAVIUS gathers the leading organisations within the field of CCS and clean coal, covering the whole value chain from research institutes to end-users. The consortium consists of 5 research organisations, 2 universities, 1 SME, 1 engineering company, 2 equipment suppliers, and 6 power generators.

Smarter and greener cities are essential to address economic, social, and environmental challenges due to the increase in urbanization, requiring informed decisions based on Internet of Things generated data. A particular challenge is the unstable power supply of cities in underdeveloped countries (e.g. South Africa), thus requiring smart energy management. Future handling of grid overload in South Africa involve demand-response mechanisms, installing small devices at the end-user, communicating over different network technologies to a central controller, allowing loads to be measured and limited if necessary. Further challenges are the deployment of affordable smart sensors (e.g. ABS air sensors) as well as gathering information from nodes with limited power. In scenarios from energy consumption to waste bin levels, data is either sent over IP networks (which delivers data immediately) or collected in a delay tolerant mode by mobile devices of individuals or crowds. In delay tolerant mode the data is stored locally, to be delivered when a suitable network is reached. In cases of open data collection the devices in this Future Internet realm are targets of security attacks and might be vendor-locked with proprietary software stacks. Our approach to address these issues is to interweave a sophisticated Smart City platform (CSIR) and an ETSI/oneM2M compliant Machine-to-Machine (M2M) communication framework (TUB/Fraunhofer OpenMTC) as well as a delay tolerant Smart Platform with the M2M framework. We emphasize secure identification and authentication of sensors and users as well as policy-based store and forward functionality. To validate our approach, we analyse the core developments in federated experimental facilities in Berlin (Fraunhofer) and Cape Town (UCT) using a Slice Federation Architecture (SFA) compliant testbed management framework (TUB FITeagle) and follow an empiric approach by conducting field studies in Johannesburg (CSIR/Eskom) and Spain (I2CAT/ABS).

South African President Jacob Zuma pledged that state utility Eskom will sign delayed power purchase agreement (PPA) contracts for renewables plants, offering hope of a resolution to a stand-off that has stalled the nation’s wind and solar sectors. In his state of the nation address this week Zuma restated South Africa’s commitment to the procurement programme that has driven its clean energy sector. Foreign investors have looked on in dismay as Eskom sat on PPAs to 2.2GW-worth of preferred bidders in Round 4 of the country’s renewables programme, announced as long ago as April 2015. Eskom – which the renewables sector has accused of favouring nuclear – claimed the renewables programme was loading unsustainable costs onto the national power system. But Zuma said this week: “Eskom will sign the outstanding power purchase agreements for renewable energy in line with the procured rounds.” He added: “Government is committed to the overall Independent Power Producer Programme and we are expanding the programme to other sources of energy including coal and gas, in addition to renewable energy.” Zuma’s signal was welcomed by the South African Renewable Energy Council (Sarec), which has previously said it may resort to legal action to end the impasse. Sarec chair Brenda Martin told Recharge: “We now look forward to the identification of PPA signature dates, so that South Africa’s well-oiled independent power procurement programme process can continue, and so that construction of the next set of renewable power plants can begin. “The approximately 57bn rand ($4.25bn) worth of waiting renewable power investment that had been secured under the programme in 2015, can now enter the economy. In addition, up to 15,000 jobs associated with the power procured in 2015, can now be realised.” The South African Photovoltaic Industry Association (SAPVIA) added: “The announcement that Eskom will sign the outstanding Power Purchase Agreements in the Renewable Energy IPP Programme sends a strong message to investors that the renewable energy industry is very much open for business. “We now hope that Eskom heeds the President’s commitment to finalise these agreements and the minister moves ahead with the announcement of the expedited round.”

JOHANNESBURG (Reuters) - South African power provider Eskom has proposed building a nuclear power station on a site that may be at risk of surge storms and tsunamis, a geological report suggests, but the state-owned utility disputes the findings. South Africa has the continent's only nuclear power station and plans to expand nuclear power generation to meet growing electricity demand in Africa's most industrisalised country. The report by Maarten de Wit, a professor at the Nelson Mandela Metropolitan University and director of the Africa Earth Observatory Network, a research institute, says canyons in the bedrock would need to be secured. "If you are going to build anything on that, it's pretty prone to storms, sea level rises and tsunamis," De Wit told Reuters on Friday. The site at Thyspunt, near Port Elizabeth in the Nelson Mandela Bay municipality, is on the Indian Ocean coastline. The report also showed seismic activity along dormant fault lines near the site that could trigger submarine landslides. Any such activity "is likely to generate a large submarine slump, and a possible significant local tsunami that would affect the coastal region, including Thyspunt," the report said, warning that a plant at Thyspunt could be at risk of devastation similar that in Fukushima in Japan in 2011. The utility has applied to the nuclear regulator for licenses to build nuclear plants at Thyspunt and Duynefontein in the Western Cape province. The regulator has pledged thorough safety assessments. "We have defined the height at which we have to build the plant to ensure that we ... avoid those tsunamis," Eskom's Chief Nuclear Officer David Nicholls told Reuters. "That does include an allowance for global warming and average sea temperature rising," he added.

South Africa's Finance Minister Pravin Gordhan is popular with foreign investors but is seen as being at loggerheads with President Jacob Zuma (AFP Photo/Mike Hutchings) Pretoria (AFP) - South Africa's Finance Minister Pravin Gordhan delivers the annual budget in parliament Wednesday as he battles to revive the economy and head off loyalists of the president who seek to oust him. Gordhan, a popular figure in South Africa and among international investors, is widely seen as being at loggerheads with President Jacob Zuma, who has shrugged off a series of recent corruption scandals. The ruling African National Congress (ANC) has been engulfed by friction between Zuma's plans for funding "radical economic transformation" and Gordhan's stand against graft and uncontrolled expenditure. "The budget will allow Gordhan to show his independence as the head of treasury and not be influenced by politics," political analyst Mcebisi Ndletyana told AFP. "But he also has to find some money to support Zuma's projects -- that could prove to be very difficult in this economic climate." Gordhan last year faced fraud charges that were criticised as a move against him by Zuma's associates as political turmoil spooked investors and saw the rand plummet. The charges were dropped at the last minute, exposing tensions in the ANC as several ministers came out in Gordhan's support. The ANC youth league, women's league and its military veterans association have all called for him to resign. Gordhan's future has come under the spotlight again ahead of the budget, with speculation of an imminent cabinet reshuffle to axe him -- a step likely to trigger another crisis of confidence in the markets. Uncertainty increased last week with the announcement that Zuma-ally Brian Molefe, the former chief executive of the state-owned power generator Eskom, was heading for parliament as a new lawmaker. "You don't bring someone of Molefe's calibre into parliament just to make him a backbencher," said Ndletyana. In a pre-budget interview with television news channel eNCA, Gordhan, 67, admitted that he was "not indispensible", adding "we are just humble civil servants." The finance minister, who is not viewed as a future presidential candidate, was appointed in 2015 to calm panicked investors when Zuma sacked two finance ministers within four days. The budget will be closely watched by rating agencies who have raised concern about the country's slow growth and bulging public sector wage bill. In December, South Africa escaped a downgrade by Standard & Poor's, which kept the country's foreign currency debt one notch above junk status but with a negative outlook. South Africa's economic growth slowed to 0.4 percent last year, while gaping inequality and 27 percent unemployment present the ANC government with major challenges. The party recorded its worst-ever election results in local polls last August. It is due to choose a new leader at the end of this year, ahead of the 2019 general election when Zuma must stand down after serving two terms.
