Centre unveils National Wind-Solar Hybrid Policy

- in Energy, Governance

New Delhi: In yet another effort to boost clean energy generation, the Ministry of New and Renewable Energy (MNRE) has unveiled a National Wind-solar Hybrid Policy that which seeks to promote new projects as well as hybridisation of the existing ones. The MNRE is also in the process of launching a scheme for new hybrid projects under this policy, which are 10 to 15 per cent cheaper than 100 per cent solar or wind projects, an official said.

The official said that under the scheme, the government would bid out wind-solar hybrid projects on tariff based competitive bidding and these projects can be set up anywhere across the country depending on feasibility and land availability with bidders. The official said the efficiency of such projects ranges from 40-45 per cent as the two clean sources compliment each other while 100 per cent solar or wind projects have efficiency of 20 to 30 per cent. Elaborating further on lower cost of hybrid project, the official said that common land, transmission system to evacuate power and equipment reduce costs by as much as 15 per cent.

The ministry had initially planned for 10 GW of such hybrid projects in the country, but now it depends on the response of bidders in view of merits over 100 per cent solar or wind projects, the official added. The objective of the policy is to provide a framework for promotion of large grid connected wind-solar PV hybrid system for efficient utilisation of transmission infrastructure and land, an MNRE statement said. The policy is also aimed at reducing the variability in renewable power generation and achieving better grid stability.

It also permits use of battery storage in the hybrid project for optimising the output and further reduce the variability. The policy 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.
