MNRE Clarifies on Solar-Wind Hybrid Project Proportioning Under RPO

MNRE has now clarified that, the RPO contribution of Obligated Entities (OE) consuming energy from hybrid wind-solar power plant shall be based on the relative proportion of energy contributed by each source, calculated based on the ratio of declared capacities of each source in the PPA.

The Ministry of New and Renewable Energy (MNRE) has issued a further clarification on its ‘National Wing-Solar Hybrid Policy’, which was issued in the month of May, last year.

According to the MNRE’s hybrid policy, power procured from the hybrid project may be used for the fulfillment of solar RPO and non-solar RPO in the proportion of rated capacity of solar and wind power in the hybrid plant respectively.

The ministry has now clarified that, the RPO contribution of Obligated Entities (OE) consuming energy from hybrid wind-solar power plant shall be based on the relative proportion of energy contributed by each source, calculated based on the ratio of declared capacities of each source in the PPA.

However, if during implementation, the actual installed capacity of each source is different from that declared in the PPA, then the OE would have the option to choose the proportion of each source based on actual ratios of capacities installed of each source, and not the capacity indicated in the PPA, MNRE further clarified.

Meanwhile, the government’s motive behind the policy was to provide a framework for promotion of large grid connected wind-solar photovoltaic (PV) hybrid system for optimal and efficient utilization of transmission infrastructure and land, reducing the variability in renewable power generation and achieving better grid stability.

It also aimed to encourage new technologies, methods and wayouts involving combined operation of wind and solar PV plants.
