![]() ![]() ![]() Electricity also replaced kerosene, lowering fossil fuel emissions, reducing the danger of fires and easing health problems. Children were able to study after dark, and the number attending school doubled in two years. For example, bringing power to weavers and tailors in Barmer, an arid district in the Indian state of Rajasthan, pushed up their productivity by 50 percent and 40 percent respectively because they were able to work at night and avoid searing daytime temperatures. In India, they are likely to be the best solution for many of the 14,000 villages which the government has earmarked for electrification in the coming years under its “Power for all” initiative.Įxperience shows that when a community gets electricity, the benefits start to be realized almost immediately. In sub-Saharan Africa, where two-thirds of the population – 620 million people – live without power, microgrids could dramatically speed up economic development. Microgrids have enormous potential in India and Africa, where more than 900 million people lack access to electricity. Thanks to grid stabilizing technology, which enables high solar-energy penetration, the towns now obtain close to 60 percent of their power from solar generation, saving approximately 400,000 liters of diesel and 1,100 tonnes of greenhouse gas emissions each year. Others include the solar- and diesel-powered microgrids in the remote towns of Marble Bar and Nullagine in Western Australia. A notable example is the Azores island of Faial in the Atlantic, population 15,000, which has a self-contained microgrid powered by five wind turbines and six oil-fired generators. They lend themselves perfectly to island communities and remote villages and towns. The microgrid rovides the overall control to coordinate these resources to meet the requirements of industrial, residential or consumer loads. Microgrids integrate multiple distributed generation sources including conventional diesel and gas, and/or renewables such as solar photovoltaic (PV), wind, hydroelectric, tidal and even thermal schemes like combined heat and power (CHP), together with energy storage. ![]() They are also ideal as back-up power sources for grid-connected installations in places prone to power outages. These small-scale grids are exceptionally flexible, bringing power to remote communities and facilities that might otherwise have to wait years or even decades for a grid connection. Among the solutions ABB is championing at the COP22 climate change conference is microgrids. One is microgrids, powered by renewable energy. ![]()
