Waterborne Power
LG CNS announced on Oct. 15 that it finished the construction of two biggest waterborne solar power plants that can generate 3 MW of power in reservoirs in Sang ju, North Gyeongsang Province, and that it will operate the two solar plants for the next 20 years.
The two new solar plants encompasse a land area of approximately 64,000 square meters, ten times larger than a soccer stadium. They can produce 8600 MW/h each year, which can supply 2,400 households. The company explained that the construction is expected to decrease CO2 per year by about 3,600 tons, which is equivalent to planting 1.2 million pine trees.
There are 10 waterborne solar plants in the nation. LG CNS stressed that if 5 percent of reservoirs are utilized for generating solar power on the water, 4,170 MW of power can be secured. The amount of electricity produced would be enough to replace four nuclear power reactors.
The company was able to reduce costs using its own wireless connection boards, since power lines and communications lines were not needed. To prevent potential induced degradation (PID) usually occurring in humid areas like reservoirs, inverters that include anti-PID modules and ground-fault detection and interruption adapters were used. A real-time monitoring system was created as well in order to detect changes in the water level of reservoirs, since any change can affect waterborne solar power structures.
