Tidal barrages are among the oldest methods of tidal power generation, with tide mills being developed as early as the sixth century. In the 1960s the 1.7 megawatt Kislaya Guba Tidal Power Station in Kislaya Guba, Russia, was built. Around the same time, the 240 MW la Rance Tidal Power Station was built in Brittany, France, opened in November ...
Sihwa Lake Tidal Power Station, located in Gyeonggi Province, South Korea, is the world's largest tidal power installation, with a total power output capacity of 254 MW. The Rance Tidal Power Station , in Brittany , northwestern France, was the first large-scale tidal power station (1966), with a total power output capacity of 240 MW
The Rance Tidal Power Station. This article lists most power stations that run on tidal power, both tidal range (impoundment via a barrage) and tidal stream (harnessing currents). Since tidal stream generators are an immature technology, no technology has yet emerged as the clear standard.
Tidal power contributes a very small proportion of the electricity generation in the United Kingdom, but it could provide a meaningful amount of predictable renewable energy in future. Several tidal stream turbines to harness currents flowing around the coastline have been developed and tested in the UK, and some of the world's first tidal ...
Two types of Tidal Stream Generators Evopod - A semi-submerged floating approach tested in Strangford Lough with SeaGen in the background.. A tidal stream generator, often referred to as a tidal energy converter (TEC), is a machine that extracts energy from moving masses of water, in particular tides, although the term is often used in reference to machines designed to extract energy from the ...
The power coefficient [9] C P (= P/P wind) is the dimensionless ratio of the extractable power P to the kinetic power P wind available in the undistributed stream. [ citation needed ] It has a maximum value C P max = 16/27 = 0.593 (or 59.3%; however, coefficients of performance are usually expressed as a decimal, not a percentage).
The first tide predicting machine (TPM) was built in 1872 by the Légé Engineering Company. [11] A model of it was exhibited at the British Association meeting in 1873 [12] (for computing 8 tidal components), followed in 1875-76 by a machine on a slightly larger scale (for computing 10 tidal components), was designed by Sir William Thomson (who later became Lord Kelvin).

Dynamic tidal power or DTP is an untried but promising technology for tidal power generation. It would involve creating a long dam -like structure perpendicular to the coast, with the option for a coast-parallel barrier at the far end, forming a large 'T' shape.
