Shares of Tata Power moved higher in early trade on March 20 after the Gujarat government approved a revised power supply agreement, enabling the company to resume operations at its 4 GW Mundra plant. The stock rose as much as 4% intraday before trading around 2.7% higher at ₹409.4 by late morning, reflecting investor optimism around improved asset utilisation.

The Mundra project, one of India’s largest imported coal-based power plants, had remained idle for nearly six months. The shutdown followed the withdrawal of a government-backed emergency clause that previously allowed power producers to pass on higher fuel costs arising from expensive imported coal. Without that compensatory mechanism, operations at the plant had become economically unviable.

The revised agreement signals a policy recalibration. Gujarat has now cleared a framework that allows Tata Power to resume long-term supply, although the arrangement remains subject to approval from the power regulator. Notably, the deal is expected to take effect retrospectively from April 2025, indicating a potential backdated financial adjustment once regulatory clearance is secured.

While the exact tariff structure has not been disclosed, available information suggests that Gujarat has capped pricing to ensure it does not exceed rates paid by other states. This condition underscores the balancing act between ensuring supply security and preventing tariff escalation for consumers.

The timing of the agreement is significant. India is preparing for peak summer electricity demand amid concerns of a potential gas shortage linked to geopolitical tensions in the Middle East. With gas-based power generation likely to face constraints, coal-fired plants are once again emerging as a critical pillar of the country’s energy mix. In this context, restarting idle capacity such as Mundra becomes strategically important for grid stability.

From a business standpoint, the development could improve capacity utilisation for Tata Power, which has faced headwinds in its thermal portfolio due to volatile fuel costs and regulatory uncertainties. However, the financial implications will depend heavily on the final tariff structure approved by regulators and the sustainability of imported coal economics.

The company’s recent financial performance reflects these pressures. In the December quarter, Tata Power reported a marginal increase in consolidated net profit to ₹1,194 crore compared to ₹1,188 crore a year earlier. However, this came alongside a notable decline in total income, which fell nearly 10% year-on-year to ₹14,269 crore. The divergence between profit and revenue indicates ongoing cost management efforts, but also highlights demand and pricing challenges in parts of the business.

For the broader power sector, the agreement may set a precedent. Imported coal-based plants across India have struggled with viability issues due to fluctuating global coal prices and rigid power purchase agreements. If similar renegotiations gain traction, it could lead to a partial revival of stranded or underutilised assets.

From an India market perspective, the development is incrementally positive for power utilities with thermal exposure. It reinforces the government’s willingness to intervene pragmatically to ensure energy security, particularly during periods of external supply risk. However, it also signals that such support may come with pricing discipline, limiting upside for generators.
