SECI has extended the last date for the submission of bids for 4 MW of grid-connected floating solar power projects with 2 MW of battery energy storage systems (BESS) to May 4, 2020. The projects will be developed at Kalpong Dam, Diglipur, North Andaman. The new deadline is. The scope of work includes the design, engineering, manufacture, dispatch, transportation, and storage of all equipment and materials such as the adequate capacity of solar modules with suitable ratings. The solar modules must qualify for the latest edition of the International Electrotechnical Commission qualification test or an equivalent by the Bureau of Indian Standards.The projects will be developed on a build-operate-own basis. SECI also set the maximum tariff payable to the developer at Rs 8 per kWh for 25 years, inclusive of all statutory taxes, duties, levies, and cess applicable currently.
While most floating solar projects are being tendered for engineering, procurement and construction (EPC), tariff-based competitive bidding is also gaining traction in this space. After the successful Rihand Dam auction, the Solar Energy Corporation of India (SECI) issued a tender for setting up 4 MW of grid-connected floating solar projects with a 2 MW battery energy storage system in Andaman with a tariff cap of Rs 8 per kWh in January 2020. The projects will be developed on a build-own-operate (BOO) basis at Kalpong Dam in Diglipur, located in northern Andaman. Apart from the 4 MW project in Andaman, SECI is developing 20 MW of floating solar PV projects equipped with 60 MW BESS on eight islands of Lakshadweep. In addition to this, in August 2019, the Bihar Renewable Energy Development Agency invited two bids of 2 MW each for developing grid-connected floating solar power projects on a BOO basis. While one project of up to 2 MW will be developed on private water bodies, another 2 MW would be developed on a government-owned water body in the state’s Darbhanga district. Ports are also making a foray in this segment. In November 2019, the Cochin Port Trust invited EPC bids for both rooftop and floating solar power projects. Initially, around 14 blocks of a residential building with flat roofs will be made available in Kochi for the projects along with about 4 km of surrounding water bodies. In October 2019, the Jawaharlal Nehru Port Trust invited bidders to provide quotations for carrying out a detailed survey for an upcoming floating solar project on its premises.
