The following table presents basic information on operational tidal power plant (arranged in increasing order of capacity) Įastern Scheldt Barrier Tidal Power PlantĢ011 How Tidal Power Plants Generate Electricity ![]() People Also Read: Organic Solar Cell Meaning ExplainedĪs of 2023, there are eight (8) operational tidal power plants in the world, and one in construction. ![]() Tidal power energy is used in all parts of the world that have installed tidal power plants in suitable offshore locations like estuaries and bays and such places include China, France, Russia, and United Kingdom.Īn example of a tidal power plant is the Bluemull Sound Tidal Stream Array, commissioned in the United Kingdom in 2016, with an operational capacity of 0.4 MW. However, while hydro energy is present in water by virtue of its existence, tidal energy can be said to be present only when water undergoes mechanical dynamics caused by surges and recessions, in sea level (also called flows and ebbs ) Many studies have viewed tidal energy as simply a variant form of hydro energy, and this is true in some sense, since both tidal and hydro energies exist because of the ability of water to act as a natural energy storage system. Such alternative definition is given below Ī tidal power plant is a system for electricity generation that harnesses renewable tidal energy from the rise and fall of sea water masses, to rotate and turbine and generate electricity. These are very important attributes, especially in the light of recent concerns with sustainable development and green economy. ![]() Īn alternative tidal power plant definition will highlight the fact that these plants harness renewable energy and produce not significant greenhouse emissions. References Tidal Power Plant DefinitionĪ tidal power plant is an energy facility that works by capturing the kinetic energy of ocean tides, and converting this energy to electricity using a number of components that include kineto-mechanical turbines and electric generators.Electromagnetic Induction (in explanation of How Tidal Power Plants Generate Electricity) Energy Capture (in explanation of How Tidal Power Plants Generate Electricity) How Tidal Power Plants Generate Electricity.Tidal energy is still at the experimental stage with research still being carried out. There is also the potential damage to the marine environment and turbines installed in large numbers. And that requires miles and miles of electricity lines. And, because tidal turbines work best in narrow channels, the places that they can be sited are limited, and these might not be near where the electricity is needed. Also, the cost of engineering and constructing machines to work on the seabed are high at the start of the project. Well, the technology is still at an early research stage, and, worldwide, tidal power doesn't generally much electricity yet. It needs no fuel, and produces no by-products or pollution. It's also a renewable, sustainable source of energy. Every day that are two high tides and two low tides that can be used to generate electricity. Unlike solar and wind energy, tidal movements are reliably constant. This powers generators that convert the kinetic energy into electrical energy that can be transported back to land through undersea cables. The kinetic energy of the water flowing back and forward with the tide is used to turn the blades of the turbines. It works like, this giant turbines are fixed to the sea floor. This is easier to capture when you’ve got water flowing through a narrow channel, such as an estuary, or between two parts of land. For tidal power to work, you need a really strong flow of water. The movement of all this water involves a lot of energy - energy that could be used to generate electricity. That's why the tide will come in and go out again from the coast twice a day. As the moon moves around the earth, these tides move, too. On the other side of the Earth, the sea is pulled a bit less, causing another high tide. Where there is sea facing the moon, this gets pulled even more causing a high tide. Just like gravity pulls objects down to the Earth, the moon's gravity pulls things towards it, too, including the earth. The tide and high seas are moved by the gravitational pull of the moon and the sun, too. ![]()
