India curtailed more than 8 TWh of solar generation in Q1 FY2027: Kearney
India curtailed more than 8 TWh of solar power generation between April and June 2026, with grid congestion identified as a major factor, according to a report by global management consulting firm Kearney. The report says the nation’s ambition to hit 500 GW of renewable energy capacity by 2030 will depend on how quickly the power transmission network scales up its planning, execution, and digitalization capabilities.

Three-month ISTS delay could widen FY27 renewable evacuation gap beyond 40GW, risking INR 18 billion in revenue
Ind-Ra projects a 32 GW mismatch between generation and transmission for projects commissioning by 2HFY27. This gap may widen to 40 GW, if interstate transmission system (ISTS) commissioning is delayed by three more months beyond the current commissioning timelines.

India needs 10 GWh of battery storage to prevent renewable energy curtailment
Ember’s analysis found that about 2.1 TWh of renewable electricity generation was curtailed in fiscal year 2025–26, equivalent to 1.3% of total renewable generation, to keep coal-fired power plants operating at their minimum technical load. The report estimates that around 10 GWh of energy storage, charged during peak midday solar generation hours, would have been sufficient to absorb this surplus renewable output, maintain coal plants above their minimum technical load, and avoid the curtailment altogether.
