A-One Steels India Ltd reports 83% renewable electricity in FY26

A-One Steels India Ltd reported that renewable sources supplied 83.20% of electricity consumption in financial year (FY) 2026, compared with 0.01% for peer Shyam Metallics and Energy Limited. The disclosed mix supports an estimated electricity-related emissions intensity of 0.08-0.10 tonnes of carbon-dioxide equivalent (tCO2e) per tonne of crude steel, against 0.5-0.6 tCO2e for a producer sourcing all electricity from the grid.

How did A-One Steels reach an 83% renewable electricity share in FY26?

A-One Steels reported an 83.20% renewable share of electricity consumption in FY26 from a mix that includes solar, wind, hydro, waste-heat recovery boilers and grid electricity. The group also has captive power plants and renewable captive power-purchase arrangements to meet electricity needs across its steel operations.

The FY26 figure was below A-One Steels’ renewable-electricity shares of 89.46% in FY25 and 88.86% in FY24. The FY26 proportion was therefore 6.26 percentage points lower than FY25, although renewable sources still accounted for more than four-fifths of electricity consumption. The disclosure considers renewable electricity consumption using figures provided by A-One Steels and does not state renewable generation volumes in megawatt-hours (MWh).

A-One Steels operates six manufacturing plants, with five in Karnataka and one in Andhra Pradesh, covering steelmaking and raw-material preparation. Its portfolio includes sponge iron, mild-steel billets, thermo-mechanically treated (TMT) bars, hot-rolled coils and pipes, cold-rolled pipes, met coke, silico manganese and ferro silicon. Electricity is used in induction-furnace steelmaking, continuous casting, rolling and finishing stages.

Why does A-One Steels’ renewable electricity mix affect emissions?

A-One Steels’ renewable electricity mix affects estimated electricity-related emissions because induction-furnace (IF) producers consume about 0.7-0.9 MWh of electricity for each tonne of product. Using a grid-emission factor of 0.71 tCO2e per MWh, the disclosure estimates that a producer purchasing all electricity from the grid would generate 0.5-0.6 tCO2e per tonne of crude steel from electricity consumption.

A-One Steels estimates its electricity-consumption emissions at 0.08-0.10 tCO2e per tonne of crude steel in FY26. The estimate incorporates adjustments for renewable-energy transactions through open access and for captive power supplied to the grid. The gap between the 0.08-0.10 tCO2e estimate and the grid-only 0.5-0.6 tCO2e estimate arises from the company’s stated 83.20% renewable electricity share.

The comparison covers electricity-related emissions rather than all emissions from making steel. A-One Steels separately reported average emissions intensity of about 0.59 tCO2e per tonne of finished steel in FY25, which uses a different output measure from the FY26 electricity estimate per tonne of crude steel. The lower electricity estimate would depend on A-One Steels maintaining a high renewable sourcing share and electricity use within the stated 0.7-0.9 MWh-per-tonne range.

How large is A-One Steels’ gap with Shyam Metallics?

A-One Steels’ FY26 renewable-electricity share was 83.19 percentage points above Shyam Metallics’ 0.01% share. Shyam Metallics’ reported proportion fell from 0.74% in FY25 to 0.01% in FY26, while A-One Steels’ share fell from 89.46% to 83.20%. The figures have different stated disclosure bases: A-One Steels’ number is based on company-provided data, while Shyam Metallics’ number is drawn from the business responsibility and sustainability section of its annual report.

Shyam Metallics was larger than A-One Steels in several FY26 production categories. Shyam Metallics produced 2,583,691 tonnes of sponge iron and 1,826,403 tonnes of billets or mild-steel ingots, compared with 252,686 tonnes and 493,371 tonnes, respectively, for A-One Steels. The electricity-sourcing comparison is thus a percentage measure rather than a comparison of absolute renewable electricity use.

Shyam Metallics had 467 megawatts of captive-power capacity in March 2026, including 9 megawatts of renewable-power capacity. A-One Steels did not disclose a comparable renewable-capacity figure in the supplied information. The 83.20% and 0.01% figures therefore compare renewable electricity consumption shares, not installed renewable generation capacity or renewable electricity volumes.

What operational factors could change A-One Steels’ renewable electricity share?

A-One Steels’ renewable electricity share can change with its renewable procurement arrangements, captive-power operations and the power requirements of its product mix. FY26 output included 493,371 tonnes of billets, 253,343 tonnes of steel bars and rods, 188,789 tonnes of mild-steel or galvanised-pipe products, and 170,384 tonnes of hot-rolled coils. These products pass through different electricity-using process stages, including melting, casting, rolling and finishing.

The Central Electricity Authority stated that about 71% of electricity generation in FY26 came from fossil-fuel sources, including coal, natural gas and diesel, while about 29% came from non-fossil sources including hydro, solar, wind and nuclear. A-One Steels’ 83.20% renewable consumption share was above the cited 29% national non-fossil generation share. The measures are not identical because one records company electricity sourcing and the other records national electricity production.

A-One Steels also operates facilities near iron-ore areas in Karnataka and within about 450 kilometres of major ports, including Krishnapatnam, Ennore, New Mangalore and Goa-Mormugao. Its direct-reduced iron facility is in the Bellary iron-ore-producing region, while the company states that producing one tonne of crude steel requires about 1.6-1.7 tonnes of iron ore. These locations concern raw-material procurement and logistics, but the supplied disclosure does not quantify their effect on renewable electricity sourcing or emissions.

Conclusion

A-One Steels’ FY26 disclosure places renewable sources at 83.20% of electricity consumption, compared with 0.01% for Shyam Metallics, and supports an estimated electricity-related emissions intensity of 0.08-0.10 tCO2e per tonne of crude steel. The estimate reflects the company’s disclosed renewable mix, captive arrangements and adjustments for open-access transactions and captive power supplied to the grid, rather than product categories alone.

The next reported measure to watch is whether A-One Steels returns to its FY25 renewable share of 89.46% after the FY26 proportion declined to 83.20%. Readers should also keep the FY25 finished-steel emissions intensity of about 0.59 tCO2e per tonne separate from the narrower FY26 electricity-related estimate, because their output measures differ.
