National Wind-Solar Hybrid Policy, 2018

Ministry of New and Renewable Energy has issued National Wind-Solar Hybrid Policy in 2018 with an aim to boost renewable power generation by promoting new projects as well as hybridization of existing ones. Some of the key features include:

• Efficient utilisation of Infrastructure: The policy provides for a comprehensive framework to promote large grid-connected wind-solar photovoltaic (PV) hybrid system for optional and efficient utilisation of transmission infrastructure and land, thereby reducing the variability in renewable power generation and achieving better grid stability.
• Technology: Policy provides for integration of both energy sources i.e. wind and solar at alternating current (AC) as well as direct current (DC) level.
• Hybrid Projects: The policy seeks to promote new hybrid projects as well as hybridisation of existing wind and solar projects.
• Procurement of Power: It will be on tariff based transparent bidding process for which Government entities may invite bids.
• Use of Battery Storage: The policy permits use of battery storage in hybrid project for optimising output and reduce variability.
• Standards and Regulations: It mandates the regulatory authorities to formulate necessary standards and regulations for wind-solar hybrid systems.

Benefits: India has major areas where the potential of both wind and solar resources can be harnessed on a high to moderate level. Also, both the resources complement each other and hybridization will further help in improving grid security and stability.
