The working basin area was originally intended to be 43 km² and has been reduced by land reclamation and freshwater dykes to 30 km², likely to be reduced further.
After the seawall was built in 1994, pollution built up in the newly created Sihwa Lake reservoir, making its water useless for agriculture. It improved after the reservoir was converted. The tidal barrage makes use of a seawall constructed in 1994 for flood mitigation and agricultural purposes.
Requiring no fuel, it has a regular and predictable energy output. With a power capacity of 254 MW, the power plant generates 552 GWh a year with a capacity factor of 24.8%.
