Energy storage: batteries, targets and long duration

Copy link to Energy storage: batteries, targets and long duration

Prelims and Mains

Energy storage does the firming a weather driven grid needs, holding the midday surplus until the evening peak.

Why the grid needs it

  • India's peak demand, 270.8 GW on 21 May 2026, now rises again at night with air conditioning.
  • Round trip efficiency is the share of stored energy that can be taken back out; pumped storage returns 70 to 80 per cent.
  • Planned battery and pumped storage discharge for roughly four to six hours, which covers the daily swing but not a long spell of low generation.
  • Long duration storage discharges for eight hours or more, and includes flow batteries, compressed air and thermal storage.

What public money pays for

  • Public money goes into both the batteries on the grid and the factories that would make their cells.
  • The production linked incentive scheme for Advanced Chemistry Cells targets 50 GWh of cell making capacity.
  • Viability gap funding covers 13.8 GWh of battery storage, with a further 30 GWh under the Power System Development Fund.
  • The Energy Storage Obligation rises from 1 per cent in 2023 to 24, to 4 per cent by 2029 to 30.

What changed

  1. 27 Jul 2026New

    • The National Electricity Plan projects 47.24 GW of battery storage and 26.69 GW of pumped storage by 2031 to 32.
    • Closed loop pumped storage projects away from rivers no longer need concurrence from the Central Electricity Authority.

    Mains: India's green transition is missing long duration storage, since the planned four to six hour systems cover the daily swing only.

Delhi Electric Vehicles Policy, 2026

Copy link to Delhi Electric Vehicles Policy, 2026

Prelims and Mains

Delhi's electric vehicle policy sets dates after which only electric vehicles of a given class may be registered in the city, beginning with three wheelers and light goods vehicles and then two wheelers.

  • Policy 2.0, effective 1 July 2026, targets 30 per cent electrification of the fleet by March 2030.

What changed

  1. 16 Jul 2026New

    • Only electric three wheelers and light goods vehicles may be registered in Delhi from 1 January 2027, and only electric two wheelers from 1 January 2028.
    • The two wheeler target is the hard one: they are about two thirds of the fleet and only 1.7 per cent are electric.
