The Ministry of New and Renewable Energy (MNRE) has updated its 2016 policy for repowering wind power projects, aiming to simplify the process of replacing older turbines. The ‘National Repowering and Life Extension Policy for Wind Power Projects 2023′ permits the replacement of older turbines with more efficient ones, even prior to reaching the conclusion of their design life, by making modifications to parts like gearbox, blades, generator, and controller. Using the most recent onshore wind turbine technologies, the policy seeks to maximise the energy yield per square km in the project area in order to optimise the efficient use of wind energy resources.
According to the policy, repowering projects can be classified either as standalone or aggregation projects. Until the power purchase agreement (PPA) expires, electricity procurement will be based on the average generation of the previous three years. The current PPA tenure will be extended for up to two years, or for a term equal to the refurbishment or repowering. The existing distribution company (discom) is not entitled to any authority or procurement over the surplus power produced, following repowering or refurbishment. The developer has the flexibility to sell the surplus power generated as per their choice, whether through the power exchange, bilateral agreements, or by engaging in short/medium/long-term PPA in accordance with prevailing laws and regulations. There is no mandatory obligation to supply the power to any discom or procurer at fixed rates. Repowering or refurbishment initiatives should be operational within 24 months from the issuance of the consent letter.
