In the last 15 months, India curtailed nearly 11 terawatt-hours of solar generation — enough electricity to power about 10 million homes, according to government data and research by energy think tank Ember. That solar power went unused even as extreme heat and poor monsoon rains drove up demand for power in India for cooling and pumping groundwater for agriculture.
India, the world’s most populous country and one of the largest emitters of climate-polluting gases, is rapidly adding clean energy, especially solar, to its power mix. However, it can’t use all the clean power it could generate because of insufficient transmission and storage capacity and the technical difficulty of shifting between fossil power and renewables.
