Cardiff based Tidal Energy Limited have been given the go-ahead for a 12 month trial period to test their new ‘Deltastream’ underwater generators. The 1.2MW plant features three generators that lie on triangular supports and generate enough electricity to power up to 1,000 homes. It has been specifically designed to be sensitive to the local environment. It has been estimated that the power of the seas off Wales could generate around 4GW of electricity.
