Tidal Engineering & Environmental Services Ltd Information

The company was formed in 2018 to develop Tidal Range as a source of electrical energy, with the objective of developing the West Somerset Lagoon Tidal Range scheme initially, to be followed later by development of other schemes. The West Somerset Lagoon is a proposed tidal range scheme which will enclose about 80km2 of the Bristol Channel between Minehead and East of Watchet. The scheme will use the water head difference between the lagoon and the Bristol Channel to generate 6.5TWh/year of energy from an installed capacity of 2.5 GW. With generation on both ebb and flood tides, the energy gap on each tide would be only about 2 to 4 hours. As tides are predictable, power output would be reliable and totally predictable for years ahead. With some short term storage, firm power could be provided. This would provide a significant addition to diversification of UK power sources. On completion it should also be possible to add around 1GW of floating solar within the lagoon.
