Tocardo develops, manufactures and sells offshore tidal turbines. Tocardo started developing their patented tidal technology over 12 years ago, and tested it for 4 years. The 100 kW T100 turbine and the larger 200kW T200 turbines are now available commercially with 500kW and 1MW expected by 2014. Tocardo’s pioneering range of water turbines generate electricity at the lowest cost per kWh through minimised maintenance and maximised power generation technology. Tocardo own unique and patented ‘bidirectional blade’ technology which allows their turbines to continue to produce electricity when tidal streams change direction, without losing efficiency. Tocardo free-flow in-stream hydro turbines can be compared to ‘underwater wind turbines’: free-standing underwater units, generating energy from currents, tidal and riverflows. They are easy to install and easy to maintain.
