South Africa\u2019s biggest cities are preparing to source their own power after the energy ministry this month approved letting them wean themselves off the state utility that\u2019s subjected cities to outages for the past 13 years.<\/p>\n
Johannesburg and Cape Town, which have a combined population of about 10 million people, plan to diversify away from the electricity produced mainly from coal by Eskom Holdings SOC Ltd to more sustainable sources such as solar and power generated from landfill gas.<\/p>\n
\u201cThe City is looking at 300 megawatts of renewable\u201d energy, Kadri Nassiep, Cape Town\u2019s executive director for energy and climate change, said by email. \u201cIf all clarity is obtained and plans forge ahead, we could start seeing greater diversification of our energy resources as a city in about three to five years time.\u201d<\/p>\n
In addition to improving security of supply, the move will allow the cities to boost their fight against climate change by using power that doesn\u2019t result in the emission of greenhouse gases. Still, it will slash revenue for Eskom, which is struggling to service a $30 billion debt bill.<\/p>\n
\u201cInternationally many cities are at the forefront of dealing with climate-change disasters and so have adopted proactive climate-change responses,\u201d Lauren Hermanus, director of Adapt, a South African company that provides consultancy services on sustainable energy, said in an interview.<\/p>\n
\u201cWe are also all aware of Eskom\u2019s related operational, governance and fiscal challenges, most clear in our bouts of load shedding,\u201d she said, using a local term for power outages.<\/p>\n
Landfill Gas<\/strong><\/p>\n South Africa produces the same quantity of greenhouse gases as the UK, which has an economy eight times larger. Eskom, which runs a fleet of coal-fired power plants, is the country\u2019s worst polluter, accounting for about 40% of the greenhouse-gas emissions.<\/p>\n Cape Town plans to build a photovoltaic solar power plant by the end of the 2023 financial year, as well as sourcing additional sustainable energy, Nassiep said. The city took the energy ministry to court this year to win the right to source its own power. The judge ruled that further negotiations with the government should take place.<\/p>\n \u201cWe intend putting out a tender for renewable-energy plants embedded in our grid in the next year and we would like to source renewable energy from large independent power producers as soon as is feasible,\u201d he said.<\/p>\n Johannesburg, South Africa\u2019s biggest city and financial hub, is considering sourcing power from solar plants and landfills, where gas from rotting garbage can be used to produce electricity.<\/p>\n The initiative is driven mainly by Eskom\u2019s unreliability, the city\u2019s commitment to reduce carbon emissions and the need to protect customers from rising power prices, said Isaac Mangena, a spokesman for Johannesburg\u2019s City Power utility.<\/p>\n \u201cCity Power is still at early stages of the initiative and we expect the process to take at least 2 years,\u201d he said.<\/p>\n
