At the ongoing United Nations Climate Change Conference, COP27, India released its long-term low-carbon development strategies. Low-carbon development of India’s electricity systems is crucial because the power sector accounts for 45% of the country’s total greenhouse gas (GHG) emissions (based on emission estimates published by the Ministry of Environment, Forest and Climate Change). The power sector is a key driver for decarbonising nearly all major energy-intensive sectors as it enables the shift to renewable energy-based electricity from the current fossil fuel–based processes.
