Tata Power Mundra Restart: Govt Acts to Secure Summer Power Supply

Government Intervenes to Avert Power Shortage

The Indian government has directed Tata Power to restart its 4,000-megawatt (4GW) imported coal-fired power plant in Mundra, Gujarat. The directive, issued by the power ministry, requires the plant to operate all its units to meet an anticipated surge in electricity demand during the peak summer months. This move is a pre-emptive measure to ensure grid stability as the country braces for a strong heatwave.

The order was issued to Coastal Gujarat Power (CGPL), a subsidiary of Tata Power that operates the Mundra facility, under the provisions of Section 11 of the Electricity Act. This specific section grants the central government the authority to compel power generating companies to operate and maintain their stations to their maximum capacity in extraordinary circumstances to secure the public interest and maintain the smooth supply of electricity.

The Rationale Behind the Directive

The decision comes as India's Central Electricity Authority (CEA) projects a potential power shortage of 10-12GW during peak summer demand. The Mundra plant, a significant asset in India's power infrastructure, had been offline following a prolonged maintenance shutdown last year. Its restart is considered critical to bridging the anticipated supply-demand gap. While the current directive is specific to the Mundra plant, it sets a precedent for over 18.7GW of imported coal-fired capacity in the country, which could also be brought online if demand escalates.

Financial Hurdles and the Path to Viability

The Mundra plant's operational status has been precarious for years, primarily due to financial unviability. The facility became a loss-making enterprise after Indonesia, its primary coal supplier, changed its regulations in 2011 to link coal prices to international benchmarks. This move significantly increased fuel costs, making the plant's original long-term power purchase agreements (PPAs) unsustainable.

The prolonged shutdown resulted in substantial financial losses for Tata Power. The company reported a loss of approximately ₹800 crore in the first nine months of the 2025-26 financial year. The losses stemmed from the inability to collect capacity charges while still incurring fixed operational costs. Restarting the plant, which accounts for nearly 25% of Tata Power's total generation capacity of 16GW, is crucial for the company's financial health.

A Breakthrough Agreement with Gujarat

A significant breakthrough came when the Gujarat government approved a supplementary power purchase agreement (SPPA) between Tata Power and the state-owned distributor, Gujarat Urja Vikas Nigam (GUVNL). This revised agreement allows for a tariff adjustment, enabling Tata Power to pass through the higher costs of imported coal. The company had sought such an approval for several years to offset the financial strain.

While Gujarat is the largest offtaker of power from the Mundra plant, Tata Power will need to secure similar supplementary agreements with other states that procure electricity from the facility, including Maharashtra, Punjab, Haryana, and Rajasthan. However, the approval from Gujarat, combined with the central government's directive, has paved the way for the plant's imminent restart.

Key Data on the Mundra Plant Restart

Market Impact and Investor Confidence

The news of the impending restart was received positively by the market. Tata Power's shares surged by 5% to a new 52-week high following the announcement of the revised agreement with Gujarat. The development provides much-needed operational stability for the Mundra project and improves the company's earnings outlook. Analysts maintain a positive stance on Tata Power, with a consensus 'Strong Buy' recommendation, viewing the resolution of the Mundra issue as a key catalyst for future growth. The company's management expects a significantly stronger performance in the upcoming quarters following the plant's resumption of operations.

Broader Implications for India's Energy Security

The government's action highlights a strategic, albeit temporary, reliance on coal to ensure energy security during periods of high demand. While the country has record-high domestic coal inventories, estimated at nearly 220 million tonnes, the directive to use imported coal plants underscores the need for a diversified and flexible power generation fleet. The move is also seen as a safeguard against potential disruptions in gas supplies due to geopolitical tensions in West Asia. The successful operationalization of the Mundra plant under the new commercial terms will be closely watched as a model for other stressed power assets in the country.

Conclusion: A Strategic Restart

The restart of the Tata Power Mundra plant is a critical development for India's power sector ahead of a challenging summer. It represents a coordinated effort between the central government, a state government, and a private utility to address both energy security and the financial viability of a key infrastructure asset. As the plant ramps up its operations, it will play a vital role in stabilizing the national grid and supporting India's economic activity during the high-demand season.
