Solar mini-grids offer economic option for Nigerian electrification plans

first_imgSolar mini-grids offer economic option for Nigerian electrification plans FacebookTwitterLinkedInEmailPrint分享Quartz:Nigeria’s electricity problems mainly revolve around a power generating system that doesn’t produce enough to match demand and an ineffective tariff system that means power distributing companies can hardly make a profit.Just as crucial, there’s a significant infrastructure gap as more than half of Nigeria’s population lacks access to the national power grid. Across the country’s rural areas, the electrification rate is even lower.One way to solve the problem is to take on the expensive and difficult task of connecting tens of millions of homes to the struggling national grid. But independent solar mini-grids offer a more feasible alternative, according to analysis in a report by the Rocky Mountain Institute and the Nigerian Renewable Energy Roundtable. With large-scale solar power projects likely to be delayed by high-level red tape, freeing developers to install mini-grids for local communities is a viable panacea.The mini-grids “fill an important gap between expensive grid extension projects and low-power solutions like solar home systems” the report says. Mini-grids already exist across Nigeria. Indeed, in making its analysis, the report audits ten existing mini-grids in Nigeria which serve 2,000 households. The success of existing mini-grids which have implemented “cost-reflective tariffs and generated customer demand,” the report states, is evidence of “the potential profitability of commercial mini-grid projects.” Crucially, the market is evolving from projects backed by the government grants to viable commercial models.There’s major upside for both customers and mini-grid developers if the local market is scaled. The report forecasts that deploying 10,000 sites with an output of 100 kilowatts (kW) by 2023 would power around 14% of the population. At that scale, tariff forecasts also show mini-grid developers can generate $3 billion in annual revenue.An added boon for local communities are lower power costs in the long-term. A majority of residents in the communities served by the mini-grids report spending less on power compared to the expense of alternatives like a diesel and petrol power generator, the report says. It also projects that tariffs, currently high relative to the national grid, will fall by 60% in the next two years as more development occurs.More: The solution to Nigeria’s big electricity problem lies in thinking smalllast_img read more

President-elect Joe Biden to announce Covid task force on Monday

first_img– Advertisement – – Advertisement – President-elect Joe Biden is expected on Monday to announce the members of his coronavirus task force, who will be charged with crafting a plan to curb the spread of the coronavirus as it reaches record-high levels.The task force will be co-chaired by former Surgeon General Vivek Murthy, former Food and Drug Administration Commissioner David Kessler and Dr. Marcella Nunez-Smith of Yale University, a Biden campaign official told NBC. Axios first reported on the announcement.The announcement, which will come before the president-elect has named any of his senior White House staff or cabinet appointments, signals how high of a priority the pandemic response is to Biden.- Advertisement – “His work needs to begin right now. He needs to begin communicating the urgency of actions with the American people,” she said in a phone interview. “His biggest challenge is going to be getting people to follow his recommendations. He can have the best policies and even the best way to implement his policies, but unless you can win the hearts and minds of the American people, it’s not going to make a difference.”Wen, an emergency physician and public health professor at George Washington University, said if the country continues on its current path, the U.S. could have more than half a million Covid-19 deaths before Biden takes office.“It’s going to get much worse this winter,” she said. “We are surging all across the country. There are firestorms of Covid-19 that we’re seeing in virtually every part of the country, and it is getting worse by the day.”Dr. Megan Ranney, an emergency physician at Brown University, echoed Wen’s concerns about the months ahead.“The worst days of the pandemic are almost certainly still ahead of us,” she said. “This virus is now spread across the entire United States. When the first surge came, it was localized to the Northeast in New England, New York, New Jersey. In the second wave, it was the South and Southwest. But now we’re seeing it literally takeover hospitals across the country.”She added that a Biden presidency gives her hope of a nationally coordinated response to the pandemic, but until Jan. 20, “it’s like we’re on our own.”Ranney added that several of her “colleagues and friends,” whom she declined to name, will serve on Biden’s coronavirus task force and will help him “hit the ground running on day one” when he takes office.“But the trouble is, even with hitting the ground running on day one, it’s going to take two months to manufacture adequate PPE,” she said. “Even if on day one, he says, ‘I’m going to create a mask mandate,’ it’s going to take a while to disseminate that and to get the messaging out.”center_img Biden will not be sworn into office until Jan. 20, when epidemiologists and medical experts say the country could be in a dire situation with the pandemic, if current trends continue. On the day NBC News projected Biden would win the election, the U.S. reported its third-straight record spike in daily new coronavirus cases, according to data compiled by Johns Hopkins University.Average daily new cases are rising by at least 5% in 47 states and the District of Columbia, according to a CNBC analysis of Hopkins data. Dr. Leana Wen, the former Baltimore health commissioner, said Biden will have his work cut out for him when he assumes office in January. She added, though, that he can begin encouraging compliance with public health measures even before he officially takes office.- Advertisement – Democratic U.S. presidential nominee Joe Biden smiles as he takes off his mask to speak about the voting results of the 2020 U.S. presidential election during an appearance in Wilmington, Delaware, U.S., November 4, 2020.Kevin Lemarque | Reuterslast_img read more
