In a surprising move, the Maharashtra Electricity Regulatory Commission (MERC) has approved significantly higher electricity tariffs than those proposed by Mumbai’s major power distribution companies—Adani Electricity, Tata Power, and BEST—for the next five years (2025–26 to 2029–30).
The decision affects nearly 4.6 million consumers, with over 3.1 million residential users, especially those in high-consumption brackets (above 300 units).
Adani Electricity: Hike Despite Proposed Relief
Adani Electricity had originally proposed a uniform rate of ₹6.90/unit for both the 301–500 and 500+ unit brackets, which was lower than the existing tariffs of ₹7.45 and ₹8.55 per unit respectively. However, MERC approved a hike of ₹2–3 per unit, shocking many consumers.
Despite the hike, an Adani spokesperson highlighted year-on-year tariff reductions of 10–11.7%, claiming that fixed charges remain unchanged, and green tariff premiums have dropped to ₹0.25/unit.
BEST Consumers Face Steepest Hike
Consumers under BEST (which serves 1.06 million users, including 577,000 residential ones) are hit the hardest:
- 301–500 units: ₹9.81/unit
- 500+ units: ₹12.01/unit
These rates are ₹2–4 more than current tariffs, and even higher than what BEST had initially requested.
IMPORTANT :
🚨 Starting this month, electricity fares in Mumbai for electricity provided by Adani Electricity have increased between 9.52% and 24.07%.
The wheeling charge on each unit has also increased by 12.69%.

Tata Power Users Get Relative Relief
While MERC also approved higher tariffs than what Tata Power had proposed, the new rates offer slight relief compared to existing ones:
- 301–500 units: ₹10.79/unit (down from ₹11.62)
- 500+ units: ₹11.79/unit (down from ₹12.56)
Tata Power claims to remain Mumbai’s most affordable and reliable power company, and has also cut its Green Tariff from ₹0.66 to ₹0.25 per Kwh to promote clean energy.
Green Energy Now Cheaper Across All Providers
In a welcome shift, all three power distributors have reduced their Green Tariff premium to ₹0.25/unit, making 100% renewable energy more viable and accessible for environmentally conscious consumers.
