![]() ![]() The generation of tidal energy is conducted based on the "Earth’s oceanic tides". This increased the availability of tidal power. On the other hand, at present time, the development of the technologies that have been seen both in the design and the turbine technology. However, being a source of renewable energy, this form of energy is currently suffering from the "high cost" and the vacuity of "web spot" that is limited for the "high tidal ranges" or "flow rapidity" (Sciencedirect, 2022). The main reason for deriving such kind of energy is that for the professionals, having predictions of the source of energy is way easier in comparison to the sun and wind. Tidal energy can be referred to as a form of hydropower. This tutorial will further include the discussions regarding the method of generation of such energy along with explaining the advantages and disadvantages as well. The power generated from the current of this tidal force is generally the basic focus of the discussion of this present tutorial. ![]() Tides are defined by "very long-period waves" that move through the ocean as a response to the force of gravitation by the moon and sun on the earth. The gates are opened and the water rushing into the sea drives the turbine to generate power when a head of 1.6m or more is created between the head pond and sea side with the falling of the tide.Tidal energy is generally considered as a form of energy that can be renewable and has been provided by converting the energy that is obtained from tides into another form of power that is useful such as "electricity". The gates are closed as the incoming tides create a head pond in the lower reaches of the Annapolis River upstream of the causeway. The power plant comprises of a single four blade turbine and sluice gates. The plant utilises a causeway built in the early 1960s, which was originally designed to serve as a transportation link as well as a water control structure to prevent flooding. The plant, operated by Nova Scotia Power, came online in 1984 after four years of construction. It generates 50GWh of electricity annually to power over 4,000 homes. The Annapolis tidal power generating station located in the Annapolis Basin, a sub-basin of the Bay of Fundy in Canada, has an installed capacity of 20MW making it the world’s third biggest operating tidal power plant. The first 1MW prototype of the 22.5m tall AR1000 tidal turbine with 18m rotor diameter was deployed at the European Marine Energy Centre in 2011.Īnnapolis Royal Generating Station, Canada – 20MW Construction is expected to start for a demonstration array involving up to six AR1000 single-rotor tidal turbines in 2014 with final commissioning expected in 2015. Atlantis Resources acquired full ownership of the tidal array project in December 2013. The MyGen project was initiated in 2006 by the Scottish company MeyGen, a joint venture between the tidal technology company Atlantis Resources and Morgan Stanley. The second phase development of the project is expected to raise the total installed capacity to 398MW by 2020. The tidal array project received offshore planning consent for its 86MW first phase development from the Scottish Government towards the end of 2013. MeyGen Tidal Energy Project located in the Inner Sound of the Pentland Firth off the north coast of Caithness, Scotland, is currently the world’s biggest underwater tidal turbine power project under development. MeyGen Tidal Energy Project, Scotland – 86MW The tidal lagoon, with an estimated annual power generation capacity 400GWh, will power over 120,000 homes for 120 years. The ground breaking for the tidal power project is scheduled for 2015 while full commissioning is expected in 2018. The plant will use reversible bulb turbines to generate power as water passes in and out of the lagoon with the rise and fall of tides. The plant will be located at a site with average tidal range of 8.5m and will involve the construction of a 9.5km-long sea wall or breakwater facility to create a lagoon cordoning off 11.5km 2 of sea. The planning application for the £850m ($1.4bn) project was approved in March 2013. The 240MW Swansea Bay Tidal Lagoon project, to be built at Swansea Bay in the UK, is the world’s biggest tidal power project and will become the world’s third biggest tidal power project upon completion.
