New regulatory reforms in India clarify collective ownership and consumption rules for group captive solar projects, making them more bankable for industrial buyers seeking cost-effective green power.
Group captive solar is emerging as a practical route for industrial buyers that want renewable power without going it alone. Under India’s captive power framework, two or more consumers can jointly own a solar project through a special purpose vehicle and use the electricity it produces for their own operations. The appeal is straightforward: when the arrangement qualifies as captive generation, users can seek relief from Cross Subsidy Surcharge and, where applicable, Additional Surcharge, lowering the delivered cost of power.
The legal test turns on two core thresholds. According to the Electricity Rules, 2005, captive users must hold at least 26% of the equity in the special purpose vehicle and must consume at least 51% of the plant’s annual output. Legal analyses of the Electricity (Amendment) Rules, 2026, say the changes notified on 13 March 2026 clarified how those tests apply to group captive projects, with the 26% ownership and 51% consumption conditions now assessed collectively rather than member by member. Practitioners say the reform was meant to reduce ambiguity and improve the bankability of captive projects.
That matters in practice because compliance is not just about legal form but about annual performance. Under the updated approach described by Norton Rose Fulbright, CMS IndusLaw and other industry commentators, the collective holding of captive users in the project vehicle has to clear the ownership threshold, while the plant’s output must also be largely absorbed by those users over the year. The same analyses note that any individual member’s consumption can only stretch so far beyond its proportionate entitlement before it stops qualifying for captive treatment, which makes load forecasting and share allocation a central part of project design.
For industrial businesses, the structure is most attractive where electricity demand is sizeable, stable and spread across more than one related entity. A group captive model can suit manufacturers, logistics operators and other users that want long-term renewable supply but do not have enough demand to support a plant alone. It also requires a willingness to take an equity stake, sign up for a multi-year arrangement and monitor ongoing compliance closely, because a failure to meet the tests can jeopardise the surcharge exemption. In short, the model offers lower-cost green power, but only for buyers able to match commercial appetite with disciplined annual consumption.
