Discuss the significance of industrial heat electrification for India's manufacturing competitiveness and decarbonisation goals. What lessons can be drawn from India's solar PV cost-reduction experience?

Industrial heat — steam, drying, furnaces — constitutes nearly two-thirds of industrial energy demand [1], and in India is met largely by coal, furnace oil and pet coke. Electrifying this heat with renewable power is the logical next phase of an energy transition that has so far focused on mobility, irrigation and buildings.

Significance for manufacturing competitiveness

• Cost predictability: MSMEs in textiles, food processing, foundries and chemicals face volatile imported fuel prices; grid-based electric heat insulates margins from that volatility.
• Efficiency gains: electric technologies such as heat pumps and induction convert energy far more efficiently than combustion boilers, which lose a large share as flue-gas and radiation losses.
• Financing support already exists: the ADEETIE Scheme (July 2025), with a ₹1,000 crore outlay under BEE, offers 5% interest subvention to micro and small units and 3% to medium units across 60 industrial clusters [2].
• Export readiness: as importing markets price embedded carbon, low-carbon process heat protects India's export share.

Significance for decarbonisation goals

• Process heat is India's largest unaddressed industrial emission source; electrification directly abates it rather than merely improving intensity.
• It complements the shift from the PAT scheme under the Energy Conservation Act, 2001 [3] to the Carbon Credit Trading Scheme, which sets greenhouse gas intensity targets for nine energy-intensive sectors [4].
• It advances India's NDC commitments and the Net Zero–2070 pledge, while cutting local air pollution from pet coke and furnace oil.

Lessons from the solar PV experience

• Aggregated demand and reverse auctions drove tariffs to a then-historic ₹2.44/unit at Bhadla [5]; similar cluster-level aggregation can lower equipment costs for MSMEs.
• Standardised contracts and a competitive vendor ecosystem matter more than subsidy alone.
• Concessional finance plus a nodal institution de-risked early adoption — replicable through BEE and ADEETIE.
• Solar scaled because generation was measured; industrial steam is rarely metered, so audits and metering must come first.

A coordinated national blueprint — cluster planning, affordable renewable supply, workforce skilling and demonstration plants — can make heat electrification India's second decarbonisation success story, aligning industrial growth with climate commitments.
