Key Features of the Draft National Hybrid Wind –Solar Policy In India by MNRE
The Ministry of New and Renewable Energy (MNRE), Government of India has issued a draft national wind solar hybrid policy on June 14, 2016, with a target of implementing 10 GW of such hybrid capacities by FY 2022. The key objective of the policy is to promote a large grid connected wind-solar PV system for optimal and efficient utilization of transmission infrastructure and land, reducing the vari- ability in renewable power generation and thus achieving better grid stability.
ICRA notes that the national hybrid policy, although still at a draft stage now, is a step in the right direction for the promotion of renewable energy sector on a larger scale.
Given that critical infrastructure such as land & evacuation network for the wind or solar project accounts for about 10-12% of overall project cost, hybrid projects would benefit from a reduction in capital cost to some extent due to common infrastructure and land use in place. Further, the variability in generation profile is likely to be reduced to some extent by the hybridization of the wind and solar projects at same site, given that generation from both the sources is at different intervals & complimentary seasons (as solar generation is available in day time throughout a year except for winter & cloudy periods while the wind generation is throughout day & night subject to windy conditions with 65-70% of wind-based generation during May till October in a year). This in turn would partially address the concerns of distribution utilities over the grid stability arising due to the intermittent nature of wind or solar.
Key Features of the Draft National Hybrid Wind –Solar Policy
Hybridization of existing wind/solar PV plants:
Existing wind power or solar power projects, willing to install solar PV plant or wind turbine generators respectively to avail benefit of the hybrid project, may be allowed with the following conditions:
(i) The hybrid power injected into the grid will not be more than the transmission capacity/grid connectivity allowed/ sanctioned for existing wind/solar project, so that no augmentation of transmission capacity is required.
(ii) No additional connectivity/transmission capacity charges will be levied by the respective transmission entity is given that the same transmission capacity is being used.
