Building bridges: On India's solar generation, battery storage

500+ questions on Environment with explanations
📌 Summary:
-
Editorial argues that India's solar revolution is at an inflection point where battery storage is no longer optional but essential
-
India installed ~180 GW of solar by mid-2026 but faces severe curtailment due to the "duck curve" problem — solar peaks midday, demand peaks evening
-
Core argument: The gap between solar generation peak and demand peak can only be bridged by large-scale Battery Energy Storage Systems (BESS)
-
Causal chain: Without BESS → midday solar surplus → grid frequency rises → grid operators curtail solar → wasted renewable energy + financial losses for developers → reduced investor confidence → slower deployment
-
India's BESS ambition: Government targets 47 GWh of BESS by 2030 under National Electricity Plan; current installed: <5 GWh
-
Cost trajectory: Lithium-ion battery costs have fallen 90% since 2010; India can benefit but needs to build domestic manufacturing (PLI scheme for ACC batteries)
-
Historical precedent: Germany's Energiewende faced similar curtailment crises in 2010s before storage investments resolved the mismatch
-
India's specific vulnerability: Monsoon variability means solar output itself is variable for 4 months/year → storage acts as buffer
-
Solutions: Fast-track VGF scheme for BESS, mandate storage with every new solar tender, develop pumped hydro in Himalayan and Western Ghat regions, incentivise demand-side flexibility
