The Welsh government today said a buyer is being sought for the 400-kW, 39-foot-high DeltaStream turbine developed by Tidal Energy Ltd. (TEL) that has failed since its December 2015 installment at Ramsey Sound in Pembrokeshire, Wales.
The project’s total cost is estimated at £18 million (US$22.78 million).
To begin the project, TEL received an £8 million (US$10.2 million) grant for the research disbursed through the Welsh government's EU funding agency, the Welsh European Funding Office. But, according to TEL officials, mechanical failures caused the device to stop generating power in March and after failing to attain continued funding, TEL went into administration in October.
The project was meant to demonstrate the capability of DeltaStream as a tidal stream generator and provide evidence on how the device interacts with the environment around it, said Chris Williams, TEL DeltaStream project developer.
Mechanical failures and TEL’s move into administration have left the device inactive, he said.
Williams said the device developed "an intermittent fault with an active sonar" in March, which was part of the system's marine monitoring equipment.
A mechanical defect also later developed on the turbine which would have prevented it from generating, Williams said.
The marine energy industry in Wales has contributed £34.5 million (US$51.5 million) and directly created more than 99 person-years of employment, according to a 2015 report published by Marine Energy Pembrokeshire.
