Abstract: Floating photovoltaic systems or FPV systems are gaining a rapid pace of popularity in the world as well as in India. With the cost of land taking a steep rise and an ever increasing population of the country, we need to resort to proper utilization of land and continuously look for alternatives. Floating PV plant can be installed on a fresh water body (natural or artificial) such as a lake, pond, reservoir etc. This paper will discuss the FPV Technology in brief and in length the feasibility of a FPV plant to create a solar hydro hybrid with the 2000 MW Tehri Hydroelectric Dam. Lack of waste land gives an advantage towards floating PV plant for sustainable energy production. The feasibility and capacity analysis check is an original idea of the paper. A 2000 MW Floating PV plant in Tehri Reservoir will increase the installed capacity of Tehri Hydro Dam by 100%. This PV plant will produce 3125 GWh of energy annually while generating/saving Rs 1575 crores/year. It will also help us save 75700 million liters of water as a result of reduced evaporation, while also reducing CO2 emissions by 2.935 million tonnes annually.  It is expected that the research work carried out in this paper will be beneficial to the energy sector towards creation of more hybrid plants and contribute to sustainable energy production.

Keywords: Floating PV plant; Reduce CO2 emissions; reduce water evaporation; sustainable energy production; solar energy; hybrid power plants.
