Renewable Energy Ministry issues national wind-solar hybrid policy

The Union Ministry of New and Renewable Energy on May 14, 2018 issued the National Wind-Solar Hybrid Policy in New Delhi. The policy provides for the integration of both wind and solar energy sources at alternating current (AC) and direct current (DC) level.

The policy also provides for flexibility in the share of wind and solar components in the 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 recognized hybrid project.The policy also provides for the procurement of power from a hybrid project on the tariff-based transparent bidding process for which Government entities may invite bids.

The existing wind and solar projects can be hybridised with higher transmission capacity than the sanctioned one, subject to availability of margin in the existing transmission capacity. It also permits the use of battery storage in the hybrid project for optimising the output and further reduce the variability. It also requires the regulatory authorities to formulate necessary standards and regulations for wind-solar hybrid systems.
