In 2023, a total of 7.77 GW of wind-solar hybrid tenders were floated by various implementing agencies, compared to 4 GW in 2022, according to Mercom India Research.

Here is a list of the top wind-solar hybrid tenders issued in 2023:

#1 NTPC issued a tender to set up 1,500 MW of interstate transmission system (ISTS)-connected wind-solar hybrid power projects. The developers were asked to maintain an energy supply to achieve an annual supply corresponding to the annual capacity utilization factor (CUF) of not less than 80% of the declared value and not more than 120% of the declared CUF value during the power purchase agreement duration of 25 years.

#2 SJVN invited bids from developers to set up 1,500 MW ISTS-connected wind-solar hybrid power projects in India. The bidders were mandated to provide a minimum power capacity of 50 MW or more for projects connected to ISTS. This was contingent on the requirement that at least 33% of the total contracted capacity must come from one resource (either wind or solar).

#3 Rewa Ultra Mega Solar floated a 750 MW tender to develop wind-solar hybrid power projects in Madhya Pradesh on a build-own-operate basis. The tender stipulated that the solar and wind components of the hybrid power project could be located at the same or different locations. The rated power capacity of any one of the components must be at least 33% of the total contracted capacity.

#4 Tata Power invited bids to develop and procure power from 225 MW of grid-connected intrastate and interstate wind-solar hybrid power projects with a greenshoe option of 225 MW on a long-term basis. The tender mandated that the minimum project size for an intrastate hybrid power project must be 25 MW, with at least 10 MW at one site. The minimum project size for interstate projects must be 50 MW at one site, which should be interconnected to a single delivery point.

#5 Kolkata-based power utility company CESC issued a tender to set up 150 MW of ISTS-connected wind-solar hybrid power projects. CESC stated that only type-certified wind turbine models listed in the Revised List of Models and Manufacturers will be used for the projects. Also, the solar modules for the project must be from the Approved List of Models and Manufacturers issued by the Ministry of New and Renewable Energy.
