The largest floating solar power project in India is now running smoothly. With effect from midnight on July 1, 2022, NTPC declared the remaining 20 MW of the 100 MW Ramagundam Floating Solar PV Project in Telangana to be commercially operational.
The overall commercial operation of Floating Solar Capacity in the Southern Region increased to 217 MW with the operationalization of the 100-MW Solar PV Project at Ramagundam. Earlier, Shri Anand said, NTPC had announced the commercial operation of two floating solar projects: 25 MW at Simhadri in Andhra Pradesh and 92 MW at Kayamkulam in Kerala.
The 100-MW Floating Solar project at Ramagundam is endowed with advanced technology as well as environment friendly features. Constructed with financial implication of Rs. 423 crores through M/s BHEL as EPC (Engineering, Procurement and Construction) contract, the project spreads over 500 acres of its reservoir. Divided into 40 blocks, each having 2.5 MW. Each block consists of one floating platform and an array of 11,200 solar modules. The floating platform consists of one Inverter, Transformer, and a HT breaker. The solar modules are placed on floaters manufactured with HDPE (High Density Polyethylene) material.
Through a unique HMPE (High Modulus Polyethylene) rope, the complete floating system is fastened to the dead weights positioned in the balancing reservoir bed. 33KV subterranean cables are used to evacuate the power up to the current switch yard. This project is distinctive in that all of the electrical apparatus—including the inverter, transformer, HT panel, and SCADA—is also mounted on floating platforms made of ferro cement. This mechanism is anchored at the bottom using concrete blocks that are dead weights.
The most evident benefit from an environmental standpoint is the minimal amount of land needed, largely for accompanying evacuation plans. Additionally, the presence of floating solar panels reduces the rate of water evaporation from aquatic bodies, aiding in water conservation. The evaporation of about 32.5 lakh cubic metres of water annually may be stopped. The presence of a body of water beneath the solar panels keeps the temperature there stable, increasing production and efficiency. Similar to how 1,65,000 tonnes of coal use may be reduced annually, 2,10,000 tonnes of CO2 emissions can be reduced as well.
