How to open an EV charging station in Mumbai

Mumbai is the most structurally complicated city in our reference set, and the complications are not the ones people expect. Land is hard, obviously. But the thing that quietly wrecks Mumbai financial models is simpler: the tariff you looked up is probably not the tariff you will be billed on.

1. Your licensee is an open question — resolve it first

Most of Maharashtra is served by MSEDCL. Mumbai is not. The city is split across multiple licensed areas served by Adani Electricity, Tata Power and BEST, and the tariff that applies to your premises depends on which licensed area your specific address sits in.

Our own Maharashtra reference records this as a critical open question: confirm the exact distribution licensee division and the current licensee-specific tariff for the full address. For Mumbai City and Mumbai Suburban we list the likely supply as “BEST / Tata Power / Adani or other licensed supply” and note that you must confirm the exact premises and the existing bill.

Practical way to settle it: get a copy of an existing electricity bill for the premises. It names the licensee, the division and the current category. That single document resolves in a minute what a week of reading tariff orders will not.

2. The MSEDCL tariff, and why the units are not kWh

For sites on MSEDCL, the EV charging categories for FY 2026–27 read as follows. Note the unit carefully — this is the part that catches people:

Two things stand out, one good and one dangerous.

The good: LT VIII carries a nil fixed and demand charge for this period, on MSEDCL. As in Hyderabad’s LT-IX, that materially de-risks a site with uncertain early throughput — there is no monthly toll running while you build demand. Confirm it applies to your licensee; our source explicitly flags this as MSEDCL only.

The dangerous: these are kVAh rates, not kWh. A kVAh charge bills apparent energy, which includes the reactive component. The practical consequence is that a poor power factor increases your bill for the same energy actually delivered to vehicles. Power factor stops being an engineering footnote and becomes a line in your operating cost, with correction equipment as a real capex item.

One further precision from the tariff table, which we record because it is the kind of thing that causes reconciliation arguments later: the displayed LT VIII components sum to ₹9.25 while the table’s stated total is ₹9.26. Confirm which figure your billing actually applies.

3. Time of day: seasonal, and unusually generous in winter

Maharashtra applies time-of-day as percentages rather than rupee adders, and the solar-hours rebate changes with the season:

The swing from the winter solar window to the evening peak is 45 percentage points on the variable charge. On LT VIII’s ₹9.26/kVAh that is roughly the difference between about ₹6.95 and about ₹11.11 per kVAh — a computed illustration, not a published rate, and before FPPCAS, duty and other additions.

Two operational consequences worth taking seriously. First, an overnight fleet-depot pattern falls largely in the 00:00–09:00 zero-adjustment window, which is a structurally better position than evening public charging. Second, if you are pairing the site with rooftop solar, the generation profile and the rebate window coincide — the same hours are cheap twice over. Confirm category eligibility for the ToD treatment before relying on it.

4. Capital support, and how to treat it in a model

Maharashtra’s EV policy announces viability gap funding for DC charging of up to 15%, capped at ₹5 lakh or ₹10 lakh depending on category, with land and ancillary cost excluded.

Our register flags the funding and application window as unverified, and we would apply the same rule we apply everywhere: no financing credit without a written sanction. Model the project as though the subsidy does not exist, then treat it as upside if it lands. A case that only clears its hurdle with an unconfirmed grant in it is not a case that clears its hurdle.

5. The Mumbai-specific practical problems

Beyond tariff, three things shape Mumbai projects more than they do elsewhere, and we state them as advisory observation rather than sourced fact:

• Land economics dominate. With a service charge capped by regulation, high land cost per square metre is difficult to earn back on charging revenue alone. Sites attached to a business that benefits from the footfall behave very differently from standalone rented plots.
• Plot geometry is the binding constraint more often than area. Queuing space and a workable turning circle are harder to find than total square metres — the failure mode described in choosing a site.
• Existing supply arrangements are complex. In dense redeveloped premises, the metering and sub-metering position needs establishing early; our reference lists confirming LT VIII / HT IX acceptance, separate connection or sub-metering, and the treatment of ancillary loads as an open question.

6. The sequence we would follow

1. Identify the licensee from an actual bill for the premises. Nothing else proceeds reliably until this is settled.
2. Get that licensee’s current schedule for the EV category, including fixed, wheeling, FPPCAS and duty components.
3. Screen the plot for geometry and electrical sizing.
4. Establish connection feasibility and the sub-metering position with the licensee in writing.
5. Model on kVAh with a realistic power factor, and with the ToD profile that matches your expected arrival pattern by season.
6. Exclude unsanctioned subsidy from the base case.

What is still unconfirmed

For Maharashtra we have not verified from a primary source: the exact distribution licensee division and current licensee-specific tariff for a given full address (critical); LT VIII / HT IX acceptance, separate connection or sub-metering and the treatment of ancillary loads (high — avoids a billing-model mismatch); current FSA, duty, taxes, deposits, service-line augmentation and other charges (critical, and needed for capex and delivered energy cost); and the current State Nodal Agency single-window portal, VGF operational guideline, budget and application window. Three further fee entries in our register are recorded as discovery-only or confirmation-required and are not published as fees.
