This report suggests ways for India to maximise the amount and value of solar and wind power in its electricity system. It addresses demand-side flexibility, power plant flexibility, storage (pumped-storage hydro and batteries) and grid flexibility, as well as policy, market and regulatory solutions for the short to medium term. It adds to existing research by focusing on renewable integration in individual states, rather than at the national level, as the power system flexibility challenges, solutions and priorities are different in each state.
