   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 .

3. Development of tidal stream generators - Wikipedia

   en.wikipedia.org/wiki/Development_of_tidal...

   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 ...

5. Cost of electricity by source - Wikipedia

   en.wikipedia.org/wiki/Cost_of_electricity_by_source

   The levelized cost of electricity (LCOE) is a metric that attempts to compare the costs of different methods of electricity generation consistently. Though LCOE is often presented as the minimum constant price at which electricity must be sold to break even over the lifetime of the project, such a cost analysis requires assumptions about the value of various non-financial costs (environmental ...

6. Tidal farm - Wikipedia

   en.wikipedia.org/wiki/Tidal_farm

   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]

   Another study estimated power generation costs as low as 7.0 cents per kWh. [58] Comparing to other energy sources, a 2019 study by Lazard estimated the unsubsidized cost of electricity to 3.2 to 4.2 cents per kWh for Solar PV at utility scale and 2.8 to 5.4 cents per kWh for wind power. [59]
