Captive status is a genuine cost lever for industrial units generating their own power above 1 MW, but qualifying for it — and staying qualified — has specific conditions that are worth understanding before committing capital.
To qualify as a captive generating plant under the Electricity Act, 2003, the consumer — or a group of consumers — must hold at least 26% equity in the generating company and consume at least 51% of the electricity it generates. Both conditions apply together; meeting one without the other does not qualify a plant for captive status.
Captive status applications in Andhra Pradesh are filed with and approved by APERC. In Telangana, the equivalent authority is TGERC. Each commission issues its own tariff orders and compliance requirements, so a captive structure that satisfies APERC does not automatically carry over unchanged to a project across the state line in Telangana.

Banking allows a captive generator to deposit surplus generation — excess solar during the day, for instance — with the DISCOM and draw an equivalent amount back later, which matters where generation and consumption don't align hour to hour. Banking terms and permitted periods vary by state regulation.
Where a single consumer cannot meet the 51% consumption threshold alone, group captive structuring lets multiple industrial consumers pool their equity and consumption to collectively qualify. This requires careful shareholding and consumption-ratio structuring up front, since the regulator checks compliance at the group level, not just for an individual participant.
Equity and consumption ratios have to be maintained annually for captive status to remain valid — a plant that drifts below 51% consumption in a given year risks losing captive recognition for that period. This is why ongoing compliance monitoring, not just the initial application, is part of what makes a captive arrangement actually deliver its intended savings.
