Chennai Electric Buses Face Stricter Supply Checks
Chennai’s plan to add 1,520 electric buses is entering a more demanding procurement phase, with the Metropolitan Transport Corporation revising tender conditions after industry consultations. The changes extend delivery periods while imposing stronger checks on manufacturers’ production capacity. For passengers, the outcome will depend not only on how quickly buses arrive, but also on whether the larger electric fleet delivers reliable, accessible and affordable services.
The revised tenders cover 1,000 air-conditioned 12-metre buses, 220 Metro feeder buses and 300 seven-metre buses. Together, they represent a significant expansion of Chennai’s electric public transport capacity and could influence how the city reduces emissions from its heavily road-dependent transport system. For the 1,000-bus contract, MTC has reduced the assured monthly operation requirement from 6,500 km to 6,000 km per bus. Since operators receive payments linked to kilometres operated, the change reduces their minimum assured revenue while also lowering MTC’s long-term financial exposure under the 12-year Gross Cost Contract.
The corporation has simultaneously raised the bar on manufacturing capacity. Bidders must now demonstrate available production capacity equivalent to at least 60% of the quantity they seek, after accounting for existing orders. A Chartered Accountant-certified statement carrying a UDIN must support the claim.The move addresses a practical risk in large electric-bus programmes: manufacturers securing multiple contracts without enough production capacity to meet promised schedules. For Chennai, avoiding prolonged delivery delays matters because fleet expansion directly affects service frequency and the viability of public transport as an alternative to private vehicles.Delivery schedules have been relaxed across the smaller bus contracts. For the 220 Metro feeders, full delivery of five-metre buses now gets nine months instead of six, while seven-metre buses receive 12 months instead of nine. The 300-bus feeder tender follows a similar extension, with complete delivery now allowed over 12 months.
Some technical requirements have also become more flexible. Five-metre buses can use either air or mechanical suspension, while their energy benchmark has been fixed at 0.6 kWh per kilometre. The seven-metre fleet retains a 0.8 kWh/km benchmark. At the same time, MTC has reduced certain equipment requirements. The 300-bus tender now requires three driver-training simulators rather than one at every depot, while passenger display boards have fallen from four to three per bus. CCTV storage, however, has been increased from 30 to 90 days.The Metro feeder fleet will operate without conductors, making dependable onboard ticketing critical. Payment systems must support digital modes such as UPI, QR codes, NCMC and cards, while retaining cash as a fallback. For Chennai, the larger question is whether procurement changes translate into dependable daily mobility. MTC electric buses can contribute to cleaner transport only when high fleet availability, accessible boarding, adequate charging infrastructure and consistent service frequencies accompany electrification. The next test will be timely delivery and sustained operations across the city.
