Maithan Alloys Limited has informed stock exchanges that its Kalyaneshwari unit in Paschim Bardhaman, West Bengal will resume full capacity ferro alloys production with effect from May 1, 2026 — ending a period of reduced operations that has lasted nearly 21 months since August 2024.
In a regulatory filing dated April 30, 2026, the company disclosed that the Kalyaneshwari unit had been operating at reduced capacity since August 1, 2024, following intimations to the exchanges on July 27, 2024 and February 1, 2025 regarding the production curtailment. The filing confirms that full capacity operations will recommence from May 1, 2026.
Why this matters
Kalyaneshwari is Maithan Alloys’ original and largest unit, located in West Bengal’s Paschim Bardhaman district — a region with established ferro alloys manufacturing infrastructure. The company also operates Unit II at Byrnihat in Meghalaya and Unit III at the Adani Ports Special Economic Zone in Visakhapatnam, Andhra Pradesh. The curtailment at Kalyaneshwari since August 2024 would have meaningfully weighed on the company’s consolidated production volumes and revenue potential from its flagship West Bengal facility over the past seven quarters.
The resumption of full capacity at Kalyaneshwari from May 1 is a positive volume catalyst for Maithan Alloys heading into FY27. Ferro alloys — primarily manganese alloys used as inputs in steel production — are directly tied to steel industry demand cycles, and the timing of the restart coincides with a period of improving domestic steel sector activity.
The reasons behind the original capacity reduction in August 2024 — whether related to power costs, raw material availability, market conditions or plant maintenance — were not detailed in the current filing. However, the decision to restore full operations signals that the conditions that prompted the curtailment have either resolved or that the current demand and economics justify absorbing whatever costs or constraints were previously involved.
For investors tracking Maithan Alloys, the Kalyaneshwari restart represents a meaningful operating leverage event — incremental volume from a facility whose fixed costs have continued to be borne during the reduced-capacity period will carry higher marginal contribution to profitability as output normalises.
