A tidal barrage is a dam-like structure used to capture the energy from masses of water moving in and out of a bay or river due to tidal forces. [1] [2] Instead of damming water on one side like a conventional dam, a tidal barrage allows water to flow into a bay or river during high tide, and releases the water during low tide.
A barrage in Rockhampton. A tidal barrage is an artificial obstruction at the mouth of a tidal watercourse, in contrast to a normal barrage along a river's inland course.

The barrage will not create a "lagoon"—as both opponents and supporters have sometimes claimed. Tidal power stations by definition require that the tide flows through the barrage, but the tidal range in the Severn would be halved. [55] There are claims that the migration of fish would be hampered, but these are contested.
The Rance Tidal Power Station is a tidal power station located on the estuary of the Rance River in Brittany, France. [1]Opened in 1966 as the world's first tidal power station, [2] the 240-megawatt (MW) facility was the largest such power station in the world by installed capacity for 45 years until the 254-MW South Korean Sihwa Lake Tidal Power Station surpassed it in 2011.

At the same time, a tidal barrage plan was evaluated, capable of generating 700 MW. [6] A barrage scheme was abandoned in 2011, following a study by Peel Energy and the North West Development Agency. This proposal involved constructing a barrage between Dingle on the Liverpool bank and New Ferry on the Wirral bank. Although the study provided ...
Sihwa Lake Tidal Power Station is the world's largest tidal power installation, with a total power output capacity of 254 MW. When completed in 2011, it surpassed France's 240 MW Rance Tidal Power Station, which was the world's largest for 45 years. It is operated by the Korea Water Resources Corporation.
