According to South West RDA, Wave Hub will create the world’s largest test site for wave energy technology by building a grid-connected socket on the seabed, 10 miles off the coast, to which wave power devices can be connected and their performance evaluated.

This week, contractors Dawnus Construction will start preparing the site of a new sub-station that will allow electricity generated out to sea to be fed into the National Grid.

The six-month project will include the installation of more than GBP1m of electrical equipment, including a monitoring system for wave energy developers to measure how much power their devices produce.

It follows the completion in February of the first phase of work to drill a 200mt duct through sand dunes at Hayle where Wave Hub’s subsea-cable will come ashore. It will be linked to onshore cabling threaded through the duct and connected to the new sub-station.

Guy Lavender, general manager of Wave Hub, said: “This next chapter in Wave Hub’s development is a crucial part of the on-shore infrastructure we are building at Hayle and Wave Hub’s grid connectivity is part of what makes it so attractive to the marine energy industry.”

Wave Hub is being funded with GBP12.5m from the South West RDA, GBP20m from the European Regional Development Fund Convergence Programme and GBP9.5m from the UK government. It is on schedule to be completed this year with the first wave devices expected to be deployed in 2011, South West RDA said.
