India met its NDC non-fossil capacity target five years early. Critically analyse why installed capacity overstates the progress of decarbonisation, and suggest how storage and transmission can close the gap.

Under its Updated NDC, India aimed for about 50% of installed electricity capacity from non-fossil sources by 2030. It reached 50.07% (242.8 GW of 484.82 GW) in June 2025, five years early [1]. The milestone is real, but it counts capacity built, not clean power delivered, so it overstates how far India has decarbonised.

Where the milestone is genuine

• Capacity is no longer the constraint: planned solar capacity of 306 GW already exceeds the 292 GW target for 2030 [3].
• A useful long-term signal: big targets let manufacturers and grid planners invest early. The ₹2.4 lakh crore transmission plan is tied to 500 GW of renewables [2].

Why installed capacity overstates decarbonisation

• Capacity vs generation: solar and wind plants run at lower load factors than coal plants. Their share of electricity actually generated is therefore much smaller than their share of installed capacity [4].
• Contracted ≠ consumed: 43,942 MW of capacity awarded at auction had no Power Sale Agreement with any buyer (Sep 2025). DISCOMs won't commit to power whose grid connection is years away [2].
• Stranded by slow wires: transmission lines run late because of slow forest clearances and right-of-way disputes, so finished plants cannot send out their power [5].
• Evening-peak gap: solar cannot meet evening demand without storage. India needs 208 GWh of battery storage by 2030, but only about 43 GWh has VGF support [6].

Closing the gap: storage

• Scale up Viability Gap Funding (VGF) for battery storage towards the 208 GWh that the National Electricity Plan 2023 says is needed [6].
• Tender solar-plus-storage projects so DISCOMs buy power they can use at night. This matches the PM's call for round-the-clock solar and indigenous batteries [4].

Closing the gap: transmission

• Auction only where grid connection is near, and tighten the 'green shoe option', which lets winning bidders take extra capacity at the same price [2].
• Amend the GNA (General Network Access) regulations so grid corridors can be shared and stranded capacity freed up [2].
• Set time-bound clearances and a standard right-of-way compensation formula [5].
• Expand Green Energy Corridors under One Nation, One Power Grid to carry renewable power to states that are short of it [4].

India has built the capacity, but contracts, transmission lines and batteries have not kept up. The new 500 GW target [4] should come with storage targets in GWh and a goal for the share of generation. That would turn installed megawatts into clean power that is actually delivered, in line with SDG-7 and India's net-zero 2070 commitment.
