The Tamil Nadu government has announced an amended power restoration policy for windmills in the state.
The order dated January 14, 2026 stated that with respect to wind power generators commissioned before April 1, 2016, windmill owners should compulsorily opt for conversion or renovation or life extension after the completion of 20 years of operational life. For wind energy generators put into operation on or after April 1, 2016, the requirement to carry out conversion or renovation or to extend the service life can be applied after the completion of 25 years of service life.
Such projects will be considered for repowering if they lead to an increase in annual energy production. The increase will be on a pro rata basis based on the capacity restored/added through re-energisation.
As far as development charges are concerned, the amount of 30 lakh rupees per MW is meant only for incremental redevelopment capacity. However, there will be a nominal charge of Rs 5 crore per MW for existing wind capacity.
Wind farms that have reached a lifespan of 20 years and wind farms with an average production of at least 70% of rated production in the last three financial years as certified by an independent agency such as NIWE are eligible for life extension under the amended policy.
The annual banking of wind generated energy will continue and the annual banking period will be from 1st April to 31st March, the excess unused power in the banks at the end of each financial year should be paid at the rate of 75% of the tariff set by TNERC and banked power will be allowed between slots. Peak generation is allowed for adjustment during normal and off-peak hours, the policy states.
The Southern India Mills Association welcomed the amended policy and said it will enhance the competitiveness of Tamil Nadu’s textile industry vis-à-vis other states as the industry will have green energy.
