Key Messages

Keeping in view India’s recent international commitment to expand the share of renewable electricity to 40%
of total generation by 2030, this paper proposes a framework for planning and addressing the implications of high share of renewables in the energy portfolio. Of the planned capacity addition target of 175 Giga Watt (GW) for renewables, wind and solar energy sources form a predominant share of 160 GW. These sources are inherently intermittent in nature. For effective integration of these sources, a system-level framework is required to understand the impact – in terms of resource availability, land utilization, technology options, economics, evacuation infrastructure and the need for storage.There are multiple stakeholders involved in the planning and implementation of policies, both at the state and central levels.This framework will aid stakeholders to envision the impact of varying the share of renewables in the future energy mix over the medium to long-term period. Additionally, it can test specific policy levers to plan for a high share of renewables (up to 100%) in the energy mix. The framework is expected to facilitate the decision making process by incorporating inputs from multiple energy and power sector entities, thereby providing an integrated visual representation of the current and future energy situation in India. This framework is demonstrated for the state of Karnataka.
