AI summary

Tata Power has temporarily suspended operations at its Mundra units to address technical issues through pending overhaul work. The units generated ₹11,290 crore in turnover in FY 2024-25, about 17.5% of consolidated turnover of ₹64,502 crore. Their net worth is below 10% of the group's total. The closure is tentatively scheduled through November 30, 2025.

Likely market impact

Mundra operations disruption may weigh on near-term revenue, but their net worth is below 10% of the group's, limiting the overall impact.
