Electric Bus and Charging Infrastructure Operator Insurance in India 2026: Depot Fire, Fleet OPEX and Charge-Point Liability Under PM E-Drive

Budget 2025 set aside Rs 4,000 crore for the PM E-Drive scheme in FY26, with roughly Rs 4,391 crore earmarked for the procurement of 14,028 electric buses across nine cities with populations above 40 lakh, and Rs 2,000 crore to build about 72,300 public chargers (including 1,800 sized for buses). Convergence Energy Services Ltd (CESL) aggregates demand, and the separate PM-eBus Sewa Payment Security Mechanism, notified in October 2024 with an outlay of Rs 3,435 crore, backs operator payments for up to twelve years per bus. By early 2026 tenders for 6,228 buses had concluded and Letters of Award for 4,720 buses were issued, with the first operational fleets rolling under the scheme.

The insurance question turns on how these contracts allocate ownership and revenue. Most e-bus deployments run on a gross-cost-contract (GCC) basis: the private operator (the concessionaire) owns, operates, and maintains the buses and is paid a fixed rate per kilometre, while the State Transport Undertaking or Public Transport Authority collects the fare box. That split matters because the party that owns the asset and earns the availability payment is usually the party contractually obliged to insure it, not the government agency whose name appears on the route.

So a broker placing this account is really insuring two businesses at once. One is a transport operator running a depot full of high-value rolling stock on thin per-kilometre margins. The other, where the same group also runs public charging, is a charge-point operator (CPO) exposing the public to high-voltage equipment. Reading the concession agreement first, before quoting, is what separates a priced programme from a mispriced one, because the penalty and indemnity clauses in that agreement decide where the loss actually lands.

The defining property exposure of an e-bus operation is the depot at night. A single depot for a 150-bus fleet can hold several hundred kilowatt-hours of lithium chemistry per vehicle, all charging in close proximity during the same overnight window, alongside the pantograph or plug-in chargers themselves. A thermal runaway event in one bus battery, or an arc-fault in a charger cabinet, can propagate across parked rows because the fire load and the ignition sources sit together. This is a genuine aggregation exposure, not a single-vehicle risk.

Property cover for the depot structure, charging equipment, workshop, and stored spares is written on the Bharat Sookshma Udyam Suraksha or Bharat Laghu Udyam Suraksha wordings for values up to Rs 50 crore, and on the Standard Fire and Special Perils policy above that. Underwriters increasingly want to see charger placement, battery-management-system alarms, fire compartmentation between charging bays, and spacing between parked buses before they settle rate and deductible.

Two clauses deserve a hard read. The average clause will cut any claim proportionately if the depot and its contents are under-insured on a reinstatement-value basis, which is easy to trigger when battery and charger prices move. And the exclusions around self-ignition, electrical breakdown, and experimental equipment can be read narrowly by an insurer to contest an EV fire. Both points should be settled in the wording, not argued during a claim.

Each e-bus is a transport vehicle under the Motor Vehicles Act, 1988, so third-party liability cover under Section 146 is compulsory, and own-damage cover is a commercial decision the concession agreement usually makes mandatory. The own-damage section on an electric bus carries valuation questions that a diesel fleet never raised: the battery pack can be 35 to 45 percent of vehicle value, its replacement cost falls over the policy period, and total-loss settlement turns on whether the sum insured tracks a declining or a fixed value. Getting the sum insured basis wrong understates premium and overstates recovery.

The commercial heart of a GCC operator is the availability payment. The operator is paid per kilometre only for buses that run, and the concession imposes penalties for shortfalls against a committed daily availability. A depot fire, a flood, or a mass battery recall can strand a large share of the fleet at once. Standard motor own-damage pays to repair or replace the bus, but it does not pay the per-kilometre revenue lost while the fleet is off the road, nor the availability penalty deducted by the authority.

That gap is filled, where insurers will write it, by business-interruption or contingent business-interruption cover tied to an insured physical-damage event, and by a delay-in-start-up extension on new depots still being commissioned. Brokers should also confirm how the Payment Security Mechanism interacts with cover: the PSM protects the operator against the authority defaulting on payment, which is a credit risk, and does not respond to physical damage or business interruption. The two sit side by side and neither replaces the other.

A public charging site is the point where a commercial operator exposes the general public to high-voltage direct-current equipment, cables handled in the open, and vehicles that occasionally catch fire while charging. This is a distinct liability profile from the depot, and it is the exposure the siblings on commercial motor, battery energy storage, and battery recycling do not reach.

The primary cover is a public-liability policy responding to third-party bodily injury and property damage at the site: an electrocution or arc-flash injury to a member of the public, a fire that spreads from a charging vehicle to an adjacent car or building, or a trip-and-fall over charging cables. Note that the Public Liability Insurance Act, 1991 imposes compulsory no-fault cover only on handlers of notified hazardous substances, which a charging forecourt is generally not, so the commercial public-liability policy here is voluntary and its limit is a judgement call the broker must size against footfall and site value.

Where the operator also owns the chargers, a product-liability angle appears if a defective charger injures a user, and the third-party-liability boundary between the charger OEM, the site host, and the CPO should be pinned in the wording. Contractual liability assumed under the site-host or concession agreement is frequently excluded by default, and needs an express write-back if the operator has signed up to indemnify the landlord or the authority.

Between the catastrophic fire and the routine crash sits a band of loss that operators consistently under-insure: the equipment failing without an external accident. A charger power module, a transformer at the depot substation, a pantograph, or a battery pack degrading below its warranted state of health are machinery-breakdown and electronic-equipment exposures, not fire or motor claims.

Machinery-breakdown cover responds to sudden and unforeseen internal failure of the chargers and depot electricals, and an electronic-equipment section covers the control boards, payment terminals, and telemetry that a modern charge point cannot run without. Both carry their own deductibles and their own exclusion for gradual deterioration, which is exactly where battery degradation claims are contested. An operator expecting insurance to cover a pack that simply aged out of warranty will find that outcome sitting on the wrong side of the wear-and-tear exclusion.

The warranty position needs mapping alongside the policy. Battery packs and chargers typically carry OEM warranties of several years, and cover is designed to sit above the warranty, not to duplicate it. A deductible set below the point where the warranty responds simply hands the insurer a subrogation argument, or funds a claim the OEM should have borne.

Grid-tie brings a further exposure. Bus depots and large charging hubs draw heavily and can suffer, or cause, voltage transients and outages. Damage to the operator's own switchgear from a grid disturbance is an equipment claim, while the operator's liability for feeding a fault back into the distribution network is a liability question. Non-damage business interruption from a prolonged grid outage, absent physical damage, generally falls outside standard cover and should be flagged to the client rather than assumed.

Placing this account well means treating it as one programme with several interlocking sections rather than a stack of unrelated policies. The starting point is an honest schedule of values: buses at a correctly stated sum insured, the depot and chargers on a reinstatement-value basis, and business-interruption limits sized to the availability payments and penalties actually written into the concession agreement.

Aggregation is the discipline that most often gets missed. Because hundreds of batteries and their chargers sit in one depot overnight, the realistic maximum loss is not one bus but a large slice of the fleet plus the building. The property limit, the motor fleet exposure, and any business-interruption indemnity period should be tested against that single-depot scenario, and the broker should know how co-insurance or reinsurance treaty terms respond to a loss of that size before binding.

Several wording points decide whether the programme holds together:

• The deductible structure across motor, property, and machinery-breakdown, so a single fire event does not stack three separate excesses against the operator.
• Contractual-liability write-backs matching the indemnities the operator has actually given to the authority and the site host.
• Clarity on which section, motor or fire, responds to a battery fire, and confirmation there is no double exclusion leaving it uninsured.
• Alignment of the indemnity period with the real time to re-procure buses and rebuild a depot, which can run well beyond twelve months.

Under a per-kilometre GCC with thin margins, an uninsured aggregation loss or a contested battery-fire claim can end the concession. The value a broker adds is in the wording detail, not the headline premium, and that detail is where the account is won or lost.

The PM E-Drive and PM-eBus Sewa build-out is moving fast, and the operators winning these concessions are signing multi-year obligations before their insurance programmes are fully tested against a real depot-scale loss. The recurring theme across every section above is the same: the difference between a covered loss and a declined one lives in the exact wording of the exclusions, the write-backs, and the boundaries between the motor, fire, liability, and machinery sections.

That is precisely the comparison work that is hard to do by hand across dozens of insurer wordings. Sarvada maintains a searchable index of Indian insurer policy wordings, so a broker structuring an e-bus or charge-point-operator programme can check how a given insurer treats battery self-ignition, EV fire at a public charger, contractual liability, or the average clause on a depot, across carriers, in one place.
