Marine energy developer Minesto has completed the second offshore installation phase of its DG500 project in Wales. Having installed the tether, micro grid system buoy and umbilical, all supporting components and systems needed to deliver the power produced by Minesto’s first system of the unique Deep Green technology in Utility Scale are now in place

The Holyhead Deep site is in close proximity to the West Anglesey Demonstration Zone, an area which has been identified as a suitable location for installation of marine energy devices in the short to medium term.
“We are very pleased to have finished this second step towards commissioning our DG500 device in Holyhead Deep”, said Minesto’s Chief Operating Officer David Collier. “The offshore operations team in Holyhead, with support from colleagues in Sweden and Northern Ireland, has made great efforts in executing the installation activities undertaken so far in a safe and resourceful way.”
Installation of the micro grid system buoy that will be used to handle and analyze electricity generated by Minesto’s DG500 marine energy converter was followed up with installation of the tether, which connects the power plant to the seabed foundation as well as holding power and data communications cables.
After that, the umbilical connecting the DG500 device with the MGS buoy was installed, completing the balance of plant installation works at the Holyhead Deep site.
This is the first tidal energy project in the world targeting the power of low-velocity currents. Once fully installed, the 10MW Deep Green array will supply local, safe and clean electricity to the equivalent of more than 8,000 Welsh household
Minesto's long-term plan is to expand the Holyhead Deep site to a commercial tidal energy array with a total installed capacity of up to 80MW. Minesto intends to develop the site in phases as part of a deploy-and-monitor approach.
