Wind power is now cost competitive with new coal-fired generation in India, according to a report from HSBC [pdf]. Falling costs are just one reason for the increased interest in wind. For the first time, India has identified water as a scare natural resource in its most recent five-year plan. Nearly 90 percent of India’s industrial water demand comes from thermal power plants, according to the HSBC report.The appeal of some renewables, such as wind and solar photovoltaic, is that they use far less water than coal, nuclear, or natural gas power plants. Across the globe, water stress is growing within the energy industry and power plants have to partially shut down when there isn’t enough water for cooling. In India, water shortages just before monsoon season in 2012 forced hydro generation and thermal power plants to partially close.
India needs all the power it can get. Last July, a sweeping power outage left about 700 million people without power. Outages are a daily occurrence in India, although usually not at that scale, because of a dearth of generation coupled with an outdated grid. The Central Electricity Authority estimates India has a peak deficit of 12 gigawatts.
The latest five-year plan calls for a doubling of renewable energy from the previous plan, including 15 gigawatts of wind, 10 gigawatts of solar, 2 gigawatts of small hydro and nearly 3 gigawatts of biomass. Individual Indian states have also instituted solar and wind installation targets.
