Editorial Summary: Business Standard argues that a developing super El Niño in 2026 is pushing peak electricity demand to record levels, but the Gurugram outages of May 18-20 and May 23, 2026 and the IMD’s May 24-30 red-alert heatwave across north-west India have exposed weak grids, slow battery storage scale-up, and over-reliance on thermal power for night-time demand. India must accelerate grid hardening, storage build-out, and renewable firming infrastructure to keep cooling-driven peak demand sustainable.
The 2026 Peak Demand Context
The summer of 2026 has arrived with a developing super El Niño and an IMD red alert across north-west India.
| Indicator | Value |
|---|---|
| IMD severe heatwave alert — Punjab, Haryana, Chandigarh, Delhi | May 25-27, 2026 |
| IMD severe heatwave alert — West Rajasthan | May 24-30, 2026 |
| Delhi maxima forecast | Up to 45°C |
| All-India peak power demand projection (summer 2026) | 250+ GW |
| FY25 peak demand | ~250 GW (June 2025) |
Cooling demand is the binding driver of India’s summer peak, and the trend line is structurally upward.
The Gurugram Outages — May 18-20 and May 23, 2026
Two consecutive blackouts in Gurugram exposed grid infrastructure that has not kept pace with high-temperature induced load. On May 18-20, 2026, a fire at a power grid substation triggered a 36-hour blackout that affected at least 10,000 families across 22 housing societies along the Dwarka Expressway (sectors 99, 102, 103, 107, 108 and 109). On May 23, 2026, underground feeder cables near Dwarka Expressway sectors 99-102 overheated and caught fire, disrupting electricity supply to around 4,500 families for nearly 10 hours and halting Rapid Metro services for over an hour.
The outages are not just incidents — they are signals. AT&C losses remain persistent, distribution-sector weakness, transmission congestion, and the absence of firming storage all converge on the same fault line, with the system caught between a renewables-rich daytime and a thermal-dependent evening.
Capacity vs Generation: The Structural Gap
India’s installed capacity profile is now decisively tilted toward non-fossil sources.
| Source | Installed Capacity (March 2026) |
|---|---|
| Coal | ~219 GW |
| Solar | ~150 GW |
| Wind | ~56 GW |
| Hydro (large) | ~51 GW |
| Nuclear | ~9 GW |
| Total Non-Fossil (share) | 53.2% of installed (283.46 GW of 532.74 GW total) |
But generation share tells a very different story.
| Source | Generation Share (April 2026) |
|---|---|
| Coal | 71.8% |
| Solar + Wind | ~8% |
| Hydro | ~12% |
| Nuclear | ~3% |
The arithmetic is unforgiving: capacity is not generation. Intermittency of solar and wind, the absence of firming storage, and the load profile of peak demand together mean that coal still does most of the work — especially after sundown.
The Storage Gap
Battery Energy Storage Systems (BESS)
- Operational BESS: ~50-60 MW
- NEP 2023 target — by 2027: 35 GWh BESS + 7 GW pumped storage
- NEP 2023 target — by 2030: 47 GW BESS + 27 GW pumped storage
PLI for Advanced Chemistry Cells
- Outlay: ₹18,100 crore, approved May 2021
- Phase I beneficiaries: Reliance New Energy, Ola Cell Technologies, Rajesh Exports
- Phase II (2024): Additional 10 GWh capacity
Pumped Storage Hydropower (PSH)
- Operational: ~4.7 GW
- CEA-assessed potential: ~96 GW
- Under construction: 14 projects
- Policy framework: CEA tariff guidelines for PSH (2023)
Viability Gap Funding for BESS
- Approved FY24: ₹3,760 crore for 4 GWh
The storage gap is the single most consequential bottleneck in India’s energy transition. Without firming, every megawatt of renewable capacity is a daytime megawatt only.
Grid Modernisation Initiatives
| Programme | Year | Function |
|---|---|---|
| Smart Grid Mission | 2015 | Smart grid pilots and standards |
| National Smart Grid Mission (NSGM) | 2015 | Implementation framework |
| Time-of-Day (ToD) tariffs | Notified June 2023 | Price signal for off-peak shifting |
| RDSS — Reforms-based & Results-linked Distribution Sector Scheme | FY22-26, ₹3.03 lakh crore | Discom reform |
| Green Energy Open Access Rules | 2022 | Enable RE consumer access |
Power Sector Pain Points
- Discom AT&C losses: ~15-16% (FY25)
- Inter-state transmission (ISTS) congestion
- Frequency stability with rising RE penetration
- Reactive power management challenges
Cooling Demand: The Binding Driver
The India Cooling Action Plan (ICAP, March 2019) was the country’s first national cooling plan, and its core projection has aged sharply with the climate trajectory.
- AC penetration: ~8% of households; rising rapidly
- Cooling demand growth projection (ICAP): Up to 8x by 2038
- Cooling load share of peak demand on heatwave days: Rising fast in urban centres
Cooling is no longer a discretionary load — for heat-sensitive populations, it is a survival load. The grid must be designed around it.
International Comparison
| Country | BESS Operational | Generation Mix Highlight |
|---|---|---|
| China | 60+ GW | Coal still ~60% of generation |
| United States | 26 GW | Gas 40%, coal 16%, RE 22% |
| United Kingdom | Substantial | Closed last coal plant 30 September 2024 (Ratcliffe-on-Soar) |
| Germany | Substantial | RE 50%+ of generation |
The UK’s coal exit, Germany’s renewables majority, and China’s BESS build-out all illustrate the same lesson: firming infrastructure and demand-side reform are the binding constraints, not headline capacity.
Way Forward
- Accelerate Viability Gap Funding for battery storage build-out (₹3,760 crore for 4 GWh is a start, not a destination)
- Fast-track pumped storage projects — Sharavathi, Pinnapuram, Upper Indravati and the wider 14-project pipeline
- Complete smart meter rollout — about 12 crore deployed, target 25 crore
- Operationalise demand response programmes at scale
- Strengthen cooling efficiency standards under ICAP
- Design a just transition framework for coal-dependent states aligned with the 500 GW non-fossil 2030 target
- National time-of-day tariffs to flatten the evening peak
- Resolve inter-state transmission congestion through ISTS capacity expansion

Editorial Insight
India’s energy transition is no longer a debate about installed capacity — that battle is largely won. It is now a debate about firming storage, distribution reform, and demand-side substitution. The Gurugram outage and the May 2026 heatwave are not anomalies; they are previews of every summer for the next two decades, sharpened by El Niño cycles and a steadily warming baseline. Capacity is not generation, and generation is not reliability. The 500 GW non-fossil target by 2030 will deliver megawatts. Whether those megawatts deliver reliability depends on whether 47 GW of BESS, 27 GW of pumped storage, and a hardened distribution grid arrive on schedule — and whether discoms are reformed before storage scales, not after.
