Ceat Limited increases stake in solar arm Greenzest to power its energy transition strategy

Mumbai-based tyre manufacturer Ceat Limited has announced a further investment of ₹3.5 crore in Greenzest Solar Private Limited, a strategic move aimed at strengthening its captive solar power capabilities. The new capital infusion will increase Ceat’s equity stake in the solar energy special purpose vehicle (SPV) to 27.52%, according to a regulatory filing.

Greenzest Solar was formed specifically to oversee the construction, operation, and maintenance of a captive solar power generation facility that supplies electricity exclusively to Ceat’s manufacturing units. The energy generated from this solar plant is intended to directly offset Ceat’s conventional grid power usage, as the tyre manufacturer steps up efforts to transition to cleaner energy sources in line with corporate sustainability goals.

What is the purpose behind Ceat’s latest ₹3.5 crore investment in Greenzest Solar?

Ceat Limited will subscribe to 437,500 equity shares in Greenzest Solar, with each share having a face value of ₹10, priced at a premium of ₹70 per share—bringing the total subscription cost to ₹80 per share. This follows earlier rounds of investment through which Ceat already secured a significant minority position in the SPV.

The rationale behind this fresh round of equity capital is to deepen Ceat’s control and oversight of the solar project operations, allowing the tyre manufacturer to better manage its long-term power procurement costs and improve environmental performance. By holding more than one-fourth of the SPV’s equity, Ceat also strengthens its influence over board-level decisions and governance structures, critical in an energy transition scenario where reliability of captive power sources can impact production timelines and cost margins.

How does Greenzest Solar support Ceat’s manufacturing operations?

Greenzest Solar Private Limited has been set up exclusively to support Ceat’s captive energy requirements. Under India’s Electricity Act and related captive power consumption guidelines, a manufacturing company can source energy directly from its own generating units or dedicated SPVs, provided it owns at least 26% equity and consumes at least 51% of the power generated.

With the latest investment increasing Ceat’s equity holding to 27.52%, the tyre manufacturer remains compliant with these rules and is eligible to claim the regulatory and financial benefits associated with captive consumption. This structure allows Ceat to bypass distribution companies (discoms) and avoid hefty cross-subsidy charges or wheeling losses, resulting in improved power cost economics over the long term.

The investment also signals Ceat’s commitment to decarbonizing its manufacturing operations, aligning with broader environmental, social, and governance (ESG) benchmarks being adopted across the global automotive and tyre sectors.

Why are Indian tyre manufacturers like Ceat prioritizing captive solar power?

Tyre manufacturing is a power-intensive industry that relies heavily on stable and cost-effective electricity for operations such as vulcanization, mixing, curing, and extrusion. The move toward captive renewable energy—particularly solar—has gained momentum in India due to rising grid tariffs, increased pressure to lower carbon emissions, and improved availability of utility-scale and rooftop solar solutions.

By securing captive power from Greenzest Solar, Ceat not only insulates itself from volatile electricity prices but also positions itself to meet the carbon disclosure and sustainability targets set by international investors and OEM clients. With electric vehicles gaining traction, OEMs have begun demanding greener supply chains, prompting component makers like Ceat to integrate renewable energy into their operations more aggressively.

Analysts following India’s industrial renewable energy segment have noted that captive solar usage by manufacturing firms has grown significantly in recent years. According to industry data available in July 2022, India’s captive solar market was expected to cross 5 GW in cumulative capacity by the end of FY2023, driven largely by sectors such as automotive components, cement, steel, and textiles.

What is the financial structure of Ceat’s share subscription in Greenzest Solar?

The ₹3.5 crore investment will be made through direct equity subscription into Greenzest Solar by Ceat Limited. Each share, with a face value of ₹10, carries a premium of ₹70, taking the all-in cost per share to ₹80. With 437,500 shares being subscribed, the total outlay stands at ₹3.5 crore, and Ceat’s equity stake will climb to 27.52%, giving it a stronger say in key operational and board-level decisions.

This pricing suggests that Greenzest Solar is being valued in a range that reflects both current generation capacity and future project pipeline potential, including additional solar installations that may be developed in support of Ceat’s expansion plans.

How does this fit into Ceat Limited’s broader sustainability goals?

Ceat Limited has steadily been investing in green infrastructure to reduce its carbon footprint and energy costs. The company’s commitment to renewable energy is part of a larger sustainability initiative that includes water recycling, solid waste reduction, and process-level efficiency upgrades across its manufacturing plants located in Maharashtra, Tamil Nadu, and Gujarat.

While Greenzest Solar plays a pivotal role in the renewable energy vertical, Ceat has also undertaken other measures such as integrating energy-efficient curing presses and adopting alternate fuel sources to reduce dependency on fossil fuels.

By increasing its stake in Greenzest Solar, Ceat is reinforcing its strategic alignment with ESG objectives, which are increasingly influencing institutional investor sentiment. Publicly listed companies in India, especially those in resource-intensive industries, are seeing increased scrutiny over their environmental practices, and investments such as this one help signal long-term resilience and accountability.

How are institutional investors likely to view this move?

While the investment size of ₹3.5 crore is relatively modest in the context of Ceat’s broader capital expenditure and operating budgets, institutional observers are likely to view the move positively. It aligns with emerging global trends around green financing, responsible manufacturing, and energy security.

Although no specific analyst commentary was available in the public domain as of July 30, 2022, generic sentiment around corporate adoption of captive solar power has been favorable. Market watchers have consistently indicated that Indian industrial firms with captive solar capacity are better positioned to manage input cost volatility and demonstrate climate resilience.

Additionally, increased promoter or parent-level equity infusion into renewable SPVs is often interpreted as a sign of commitment and operational trust in the captive model, particularly in sectors with tight operating margins.
