Wind-solar hybrid (WSH) power, which harnesses both solar and wind energy, is fast emerging as a viable new renewable energy (RE) option in India, according to a Crisil Research study.
About 15 GW of WSH power will come up over the next five years, riding on strong support from Solar Energy Corporation of India and several state governments. Of the 15 GW of WSH power, about 10 GW is already in the works – either under construction or being tendered – and will start feeding the grid by fiscal 2024.
In comparison, the country had 37.69 GW of standalone wind energy capacity and 35 GW of solar capacity as of fiscal 2020, it said.
“We expect the WSH market to grow and evolve as the number of projects and developers who seek to unlock value from the hybrid increases. However, the availability of good sites with strong irradiation and high wind speeds would be a key challenge, as evident in waning developer interest in the wind energy sector,” said Rahul Prithiani, Director at Crisil Research.
There are proposals to set up about 3.9 GW of pure-play WSH projects and about 4.5 GW of WSH projects with energy storage systems currently. The WSH projects with storage are capable of catering to peak load generation, besides improving the capacity utilisation factor.
In addition, Crisil Research expects about 1.1 GW of hybrid projects to come up as part of about 5.4 GW up for development under the government’s round-the-clock or RTC power scheme, which has a mandatory 51:49 blend of RE and thermal.
