Forbes reports that tidal power company Atlantis has launched its first project in Scotland - Scotland Plugs Tidal Power into Electricity Grid.

Scotland plugged the first commercial scale tidal-power turbine into the central power grid earlier this week.

Atlantis Resources, a Singapore-based marine renewables developer, installed the 1-megawatt tidal-power turbine at the European Marine Energy Centre in Orkney, Scotland.

Equipped with a rotor measuring roughly 60 feet in diameter, the three-bladed horizontal-axis AR1000 aims to be among the world’s most powerful single-rotor tidal turbine, delivering 1 MW of power from tidal resources moving at speeds of about eight feet per second.

The system weighs 1,500 tons and stands about 75 feet tall on a seabed-mounted tripod foundation.

Plans for a tidal power vessel in the Humber to generate electricity for a Hull aquarium have been approved.

The Neptune Proteus device will use the tides of the estuary to power The Deep.

The 150-tonne generator is expected to be deployed in the autumn. It is hoped five additional units will be installed in the future to generate energy for 5,000 homes.

Colin Brown, chief executive of The Deep, said the Humber had "massive" potential as a power source.

Mr Brown said: "Because of the nature of the aquarium, pumps are running 24/7 - we have a requirement for power all the time - and this one installation is anticipated to provide perhaps 30 or 40 percent of our entire electricity load."

The BBChas an article on a tidal power pilot in the Humber Estuary (the numbers below should probably read 1 MW rather than 1,000 MW) - Humber tidal project passes power tests.

A major step forward in using the tidal power of the Humber estuary to generate electricity has been completed by engineers.

Neptune Renewable Energy has said it produced power from its demonstration unit at Hull's Albert dock following three months of tests.

Now engineers are preparing to install a commercial site at Sammy's Point in the Humber estuary in early 2011.

Power from that will be used to run The Deep aquarium in Hull.

The Proteus NP 1000 tidal stream power generator weighs more than 150 tonnes and will be 20m (65ft) in length. It is made of steel buoyancy hulls carrying a turbine and 6m (19ft) rotors.

Engineers from the firm believe, that based on the dock tests, the system would be able to generate at least 1,000 megawatts and claim this could meet the energy needs of more than 500 homes.
