On June 20, 2025, pockets of Mahim West, Bandra and Santacruz in Mumbai were plunged into darkness for up to four hours, leaving thousands of households and small businesses scrambling for alternative lighting and backup power. The outages have reignited concerns over the city’s ageing power distribution network, administrative gridlocks and rising consumption that experts say threaten both daily life and economic activity in India’s financial capital.
1. What Happened?
- Incident Overview: Residents in Mahim West reported power cuts beginning around 6:15 pm local time on June 20, with supply not fully restored until after 10 pm. Similar trippings were recorded in Bandra and Santacruz at approximately 8 pm, disrupting local train services and digital payment systems.
- Immediate Causes: According to BEST Electricity Division, the outages were triggered by repeated tripping of old underground cables, exacerbated by heavy monsoon rains. A spokesperson, Mr. Rajesh Verma, noted in an official statement that “the collapse of earthen conduit housing 11 kV feeders led to abrupt load shedding as a protective measure.”
- Administrative Deadlock: The Brihanmumbai Municipal Corporation (BMC) has repeatedly withheld excavation permits needed by BEST to replace deteriorated concrete roads and install new cables, citing safety concerns and ongoing municipal projects timesofindia.indiatimes.com.
2. Expert Analysis
“Mumbai’s distribution network suffers from Transmission & Distribution (T&D) losses of nearly 18%, one of the highest among major metros,” explains Dr. Arvind Singh, Professor of Energy Systems, IIT Bombay (profile). “Aging infrastructure coupled with monsoon-induced water ingress accelerates equipment failure.”

Dr. Singh’s observations align with the Electricity Sector in India report, which records T&D losses of 17.68% in FY 2022–23, largely attributed to outdated cables, illegal tapping and inadequate maintenance en.wikipedia.org.
3. Government Data & Policy Context
- Central Electricity Authority (CEA) Findings: The CEA’s October 2024 Executive Summary highlights that Maharashtra’s urban feeders are operating at 120–130% of their designed capacity, with replacements pending due to funding constraints and land permissions cea.nic.in.
- State-Level Deficit: According to a PRS Legislative Research analysis, Maharashtra faced a 0.5% energy deficit and 1.9% peak demand shortfall in 2023–24, prompting scheduled load shedding in non-essential zones to maintain grid stability prsindia.org.
4. Timeline of Recent Outages
| Date | Localities Affected | Duration | Cause |
|---|---|---|---|
| Mar 28, 2024 | Mahapalika Marg, Marine Lines | ~1 hour | Cable tripping following heavy rains indiatoday.in |
| Apr 12, 2025 | Dadar, Matunga | 70 minutes | MSETCL transmission line trip nationalheraldindia.com |
| Jun 20, 2025 | Mahim West, Bandra, Santacruz | 3–4 hours | Underground cable failure + no excavation permit |
5 Key Takeaways
- Aging Assets: Over half of Mumbai’s distribution cabling surpasses its 25-year design life.
- Bureaucratic Hurdles: BMC’s excavation permit backlog stalls urgent upgrades.
- Rising Demand: Monsoon season spikes usage as air-cooling and lighting needs surge.
- High T&D Losses: Nearly one-fifth of generated power is lost before reaching consumers.
- Economic Impact: SMEs reliant on uninterrupted electricity report revenue losses up to ₹10,000 per hour of outage.
What Happens Next?
- Pending Permissions: BEST has submitted fresh excavation applications to the BMC, anticipating approval by late July 2025.
- RDSS Funding: Under the Revamped Distribution Sector Scheme, Maharashtra is slated to receive ₹1,200 crore in 2025–26 for network modernization—conditional on timely municipal clearances.
- Community Initiatives: Resident Welfare Associations in affected areas plan to partner with IIT Bombay for a real-time outage reporting app, aiming to reduce response time and improve accountability.
Fact-Check
| Claim | Status |
|---|---|
| “Outages are due to local protests against rate hikes.” | False. No documented protests occurred in Mahim West in June 2025; MSEDCL attributes interruptions solely to technical faults and permit delays. |
| “MSEDCL deliberately cuts power to non-paying customers.” | Misleading. While unpaid dues can trigger individual disconnections, large-scale feeder outages result from system faults, not billing enforcement. |
| “Alternative solar solutions can fully replace grid supply.” | Partially True. Rooftop solar with battery storage can offset daytime loads but cannot yet meet peak monsoon demands without grid support. |
