India Curtailed 8,133 GWh of Solar Power to Maintain Grid Security
Context
India curtailed 8,133 GWh of solar power during the April – June quarter of FY 2026-27 to maintain grid stability. The move highlights the growing challenge of integrating rapidly expanding renewable energy capacity with the country’s transmission infrastructure.
Key Highlights
- India reduced 8,133 GWh of solar power generation during the first quarter of FY 2026- 27 as the existing transmission network was unable to absorb the available renewable energy while ensuring grid stability.
- The curtailment was largely attributed to delays in the commissioning of transmission infrastructure despite the rapid expansion of utility-scale solar projects across the country.
- Despite these constraints, India’s installed solar power capacity increased to 162.15 GW by June 2026, reflecting continued progress toward the country’s renewable energy and clean energy targets.
- The government informed Parliament that renewable power generation was restricted whenever required to maintain grid security, ensuring a reliable electricity supply under varying demand and transmission conditions.
Key Concepts
- Renewable Energy Curtailment refers to the intentional reduction of electricity generation from renewable sources when the grid lacks sufficient capacity to absorb or transmit the available power without compromising system stability.
- The Green Energy Corridor (GEC) project aims to strengthen interstate and intrastate transmission networks for the seamless integration of renewable energy into the national grid.
- Grid Security refers to the ability of the power system to maintain a stable balance between electricity generation and consumption while ensuring reliable frequency, voltage, and uninterrupted power supply.
- The National Solar Mission, launched under the National Action Plan on Climate Change (NAPCC), promotes large-scale deployment of solar energy to accelerate India’s clean energy transition.
- PM Surya Ghar: Muft Bijli Yojana encourages rooftop solar adoption by providing financial assistance to households, promoting decentralised renewable energy generation and reducing dependence on conventional power sources.
