BENGAL’S SOLAR AMBITION GETS A ₹2,500-CRORE TEST: TATA POWER SEEKS STATE SUBSIDY TO BRING CLEAN ENERGY WITHIN REACH
October 15, 2026
KOLKATA, OCTOBER 15: Tata Power has urged the West Bengal government to introduce an additional subsidy for rooftop solar installations, arguing that state-level financial assistance could accelerate adoption of clean energy, particularly among lower-income households. The company has also outlined investment plans worth approximately ₹2,500 crore for solar projects in the state.
The proposal places two interconnected issues before the state government: making rooftop solar affordable for ordinary households and creating conditions that would encourage large-scale investment in renewable energy.
Sanjay Banga, chief executive officer and managing director of Tata Power Renewable Energy Ltd, said an incentive similar to those offered by Odisha, Bihar and Assam could significantly increase the uptake of residential solar systems in West Bengal.
The company’s appeal comes under the Centre’s Pradhan Mantri Surya Ghar: Muft Bijli Yojana, which provides financial assistance to eligible households installing rooftop solar systems.
SUBSIDY GAP EMERGES AS A BARRIER TO ADOPTION
Tata Power believes that the initial cost of installing rooftop solar remains a major obstacle for households, even with central government assistance. An additional state subsidy, it argues, could reduce the financial burden and make the technology accessible to a wider section of the population.
Banga pointed to state incentives in neighbouring regions, where additional assistance of approximately ₹15,000 to ₹25,000 per project is available. He urged West Bengal to consider a comparable measure to encourage faster adoption.
Under the central scheme, the subsidy for a 1-kilowatt rooftop solar installation is ₹30,000, rising to ₹78,000 for a 3-kilowatt system, according to the company’s explanation.
The proposed state-level assistance would supplement this central support rather than replace it. The objective would be to reduce the amount households must arrange themselves before they can begin generating electricity from their rooftops.
For families with limited disposable income, the upfront expenditure can be decisive in determining whether solar installation is financially viable. Tata Power’s position is that additional public assistance could help overcome this barrier and expand the scheme’s reach.
INSTALLATION NUMBERS INDICATE ROOM FOR EXPANSION
According to company data cited in the report, Tata Power has installed approximately 6,000 rooftop solar systems in West Bengal, out of nearly 22,000 households covered under the programme in the state.
The figures point to an emerging market for residential solar power, while also highlighting the scope for expanding installations.
The company launched its Ghar Ghar Solar initiative and a solar-plus-battery-storage solution in Kolkata ahead of the Durga Puja celebrations. The initiative seeks to encourage households to adopt solar power and consider storage systems that can complement electricity generated during daylight hours.
A more affordable installation model, supported by suitable financing and public incentives, could help households overcome the initial cost barrier. The company has also introduced a zero-down-payment arrangement for residential solar projects in partnership with banks, seeking to make adoption easier for customers who may struggle to fund the initial investment.
₹2,500-CRORE INVESTMENT PLAN FACES LAND CHALLENGE
Beyond residential rooftops, Tata Power is exploring investments of around ₹2,500 crore in solar projects across West Bengal, with plans involving approximately 500 MW of solar capacity.
Land availability remains a challenge for developing large-scale solar projects. The company has suggested that the state explore the development of solar parks on non-agricultural land, which could help attract developers and facilitate project implementation.
Such parks could provide a more organised framework for renewable-energy development, potentially reducing difficulties associated with securing suitable sites. The availability of appropriate land would be an important factor in translating the proposed investment into actual projects.
The proposed investment also highlights the relationship between state policy and private-sector participation. While financial incentives could stimulate household demand, land availability and supportive infrastructure would be important to the development of utility-scale solar capacity.
The investment figure represents a plan under consideration, rather than confirmation that the entire amount has already been committed or deployed.
THE POLICY CHOICE BEFORE WEST BENGAL
Tata Power’s proposal presents the West Bengal government with an opportunity to consider whether additional subsidies could accelerate the transition towards decentralised renewable energy.
Rooftop solar offers households the possibility of generating a portion of their own electricity, potentially reducing their dependence on conventional grid supply. However, the benefits available to individual consumers depend on installation costs, financing arrangements, system performance and the applicable subsidy framework.
For the state, the decision involves balancing the potential benefits of faster solar adoption against the fiscal cost of providing additional financial assistance. A carefully designed incentive would need to reach eligible households while ensuring that public support translates into additional installations.
At the same time, the proposed ₹2,500-crore investment could create opportunities for expanding solar capacity, provided the challenges surrounding land and project development can be addressed.
Tata Power’s message is clear: a combination of additional household subsidies, accessible financing and suitable land for solar parks could help West Bengal strengthen its renewable-energy market.
Whether the state adopts the proposed incentives remains to be seen. The immediate question is whether the government will supplement the Centre’s rooftop solar programme with its own financial support and establish conditions that enable the company’s investment plans to move forward.
