Between 2020 and 2025, electric buses went from minority traffic to a familiar sight on Indian roads, priced nearly 30% below diesel and backed by public procurement in most states. India went from about 500 electric buses in 2020 to over 63,000 buses contracted in 2026, with 16,000 on the road — valued at $8 billion. The government was firmly at the wheel of this transformation, and it delivered.

Contrast that with freight. Despite years of pilots, subsidies, and industry pledges, fewer than 1,000 electric heavy-duty trucks operate on Indian roads, out of a fleet of nearly four million. The global discourse on commercial vehicle electrification rests on a single proposition: As battery prices fall and electricity stays cheaper than diesel, market forces will drive the switch. This is only partly true. Cost competitiveness is a powerful tailwind, but it is also fragile, reversible, and unevenly motivating across the supply chain. The single most consequential lever available to accelerate freight electrification is a fleet electrification mandate, which compels India’s largest industrial shippers to convert diesel trucks to electric on a defined timeline.

But cost savings alone won’t do it. Indian trucks consume roughly ₹6 lakh crore of diesel every year. At today’s grid tariff of about ₹8/unit, full electrification could cut this to ₹2.1 lakh crore, a 65% saving. At renewable tariffs of ₹4/unit, savings climb to nearly ₹4.8 lakh crore, or 80%.

These same economics underpinned India’s electric bus transition, where high upfront capital costs were amortised over long-term service contracts, resulting in........
