The cost-effectiveness varies according to the site of the tidal generators. One indication of cost-effectiveness is the Gibrat ratio, which is the length of the barrage in metres divided by the annual energy production in kilowatt hours .
The Rance Tidal Power Station, a tidal barrage in France. 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 ...
Many tidal stream generators have been developed over the years to harness the power of tidal currents flowing around coastlines. These are also called tidal stream turbines (TST), tidal energy converters (TEC), or marine hydro-kinetic (MHK) generation. These turbines operate on a similar principle to wind turbines, but are designed to work in ...
Tidal stream generator. 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 ...
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 farm. A tidal farm is a group of tidal stream generators used for production of electric power. The potential of tidal farms is limited by the number of suitable sites across the globe as there are niche requirements to make a tidal farm cost effective and environmentally conscious. [1]
hide. Severn Tidal Power Feasibility Study is the name of a UK Government feasibility study into a tidal power project looking at the possibility of using the huge tidal range in the Severn Estuary and Bristol Channel to generate electricity. On 22 January 2008, the Government launched the feasibility study. [1]
