Ministry of New and Renewable Energy has issued National Wind-Solar Hybrid Policy here today. The objective of the policy is to provide a framework for promotion of large grid connected wind-solar PV hybrid system for efficient utilization of transmission infrastructure and land. It also aims at reducing the variability in renewable power generation and achieving better grid stability.
On technology front the Policy provides for integration of both the energy sources i.e. wind and solar at AC as well as DC level. The Policy also provides for flexibility in share of wind and solar components in hybrid project, subject to the condition that, rated power capacity of one resource be at least 25 per cent of the rated power capacity of other resource for it to be recognised hybrid project.
The Policy seeks to promote new hybrid projects as well as hybridisation of existing wind/solar projects. The existing wind/solar projects can be hybridised with higher transmission capacity than the sanctioned one, subject to availability of margin in the existing transmission capacity.
The Policy provides for procurement of power from a hybrid project on tariff based transparent bidding process for which Government entities may invite bids. Policy also permits use of battery storage in the hybrid project for optimising the output and further reduce the variability. It mandates the regulatory authorities to formulate necessary standards and regulations for wind-solar hybrid systems.
With significant capacity additions in renewables in recent years and with Hybrid Policy aiming at better utilisation of resources, it is envisaged that the Hybrid Policy will open-up a new area for availability of renewable power at competitive prices along with reduced variability. A scheme for new hybrid projects under the policy is also expected shortly.
