AI summary

Tata Power provided an update on the temporary suspension of operations at its Mundra units, first reported on October 17, 2025. The company says it is continuing the required corrective measures and anticipates resuming operations on a tentative basis by December 31, 2025.

Likely market impact

Extended Mundra shutdown may weigh on near-term output. A clear restart date reduces uncertainty, but any further delay remains a risk.
