The role of coal plant retrofitting strategies in developing India's net-zero power system: a data-driven sub-national analysis [PDF]

open access: yesarXiv
India set two Nationally Determined Contribution targets to achieve the net zero carbon emission goal by 2070, which requires deep decarbonization of India's power generation sector. Yet, coal power generation contributes to more than 60\% of its total power generation, and policies still permit further coal fleet expansion and lifetime extensions.
