India's Ports sector has lined up $5 billion of clean-energy and efficiency projects through 2030, according to a review of company disclosures and ministry data. About 10.2% of the pipeline is for captive or open-access renewable power, with storage and green-hydrogen pilots making up most of the rest.

Grids are the weak link. Transmission approvals and last-mile connectivity have delayed several projects by 12 months or more, and curtailment in renewable-rich regions rose 10.4% last year. A planned set of green corridors aims to address the problem, but timelines are tight.

The cost curve has moved

Customers are driving the change. Buyers in Indonesia and UAE increasingly require product-level carbon data, and a carbon border mechanism in Europe is concentrating minds. Indian exporters who can demonstrate lower embodied emissions report better pricing and longer contract tenors.

Measurement is a hurdle. Few mid-sized firms can currently produce audited scope-1 and scope-2 data, let alone scope-3, and consultants report a backlog of requests. Industry associations are developing a common template to reduce cost and improve comparability.

Policy support continues. The latest budget extended accelerated depreciation for efficiency equipment and allocated $5 billion to transmission and storage. Industry bodies welcomed the measures but asked for faster clearance of open-access applications and a standard wheeling charge across states.

“Grids, not generation, will decide how fast this goes.”

Customers and carbon pricing

The economics have shifted markedly. Delivered cost of firm renewable power for industrial users fell 11% over two years, and in several states now undercuts grid tariffs for large consumers. Infosys said its latest 25-year agreement locks in power at about 10.4% below its current average cost.

Carbon markets are maturing. The domestic compliance scheme will cover large emitters in the sector from Q3 FY27, and early trading in voluntary credits suggests prices of about $306 million per hundred tonnes. Companies are building internal carbon accounting teams, drawing talent from consulting and utilities.

Storage, hydrogen and the grid

Green hydrogen remains early but is moving from slides to steel and concrete. A consortium including Infosys has commissioned a pilot electrolyser near Kandla, with output intended for domestic fertiliser and export-grade ammonia, and the government has offered production-linked support for the first tranche.

Storage is the next lever. Pilot battery installations of 597 megawatt-hours at industrial sites are being used to shift load and avoid peak charges, and developers expect costs to fall another 10.4% by 2030. Regulators are drafting rules to let storage participate in ancillary markets.

Finance and the outlook

Finance is flowing. Green bond issuance from the sector reached $306 million this year, and development banks have extended concessional lines for efficiency retrofits. Lenders are starting to price transition risk, offering lower spreads to borrowers with credible decarbonisation plans.
