Background

Overview

This concept is crucial for India's energy security, achieving its climate change commitments (NDCs), fostering economic growth through cheaper power, and developing critical infrastructure. It involves policy, technology, and economic dimensions vital for sustainable development and energy transition.

Renewable energy integration refers to the process of seamlessly incorporating intermittent renewable power sources like solar and wind into the existing electricity grid. This involves addressing challenges related to grid stability, transmission capacity, and demand-supply balancing, often requiring advanced grid technologies and energy storage solutions.

Facts & tables

Key facts

Stranded Renewable Power

Tens of gigawatts of India's cheapest solar and wind power are stranded due to inadequate grid infrastructure.

Potential Unlocked Capacity

Upgrading the grid and adding storage can unlock 1,000 GW of new clean energy without acquiring additional land for transmission.

Accelerated Deployment

India added over 45 GW of solar and wind in 2025, matching the United States.

Cost-Effective Firm Power

Paired with low battery costs, India can deliver firm clean power at approximately ₹3.5 per kWh.
