Balance of plant contractor Jones Bros has started work on BlackRock’s three-turbine Pen Bryn Oer wind farm near Caerphilly in south Wales.
The 6MW site features Vestas V90 hardware with a power rating of 2MW and 100-metre tip height.
Pen Bryn Oer is being constructed on an old coal opencast site, which means Jones Bros will be constructing piled foundations as part of the project.
Piling works will involve drilling up to 21 holes of 20 metres in length beneath each turbine, which will then receive steel reinforcement and concrete to create a stable foundation.
Jones Bros will begin excavating the turbine bases in mid-April and the piling work is scheduled to be carried out in May.
Site agent Rhys Roberts said: “An ecologist visited the site last week and the all clear has been given to start work.
“The team is looking forward to getting its teeth into this wind farm and overcoming the geotechnical challenges being introduced.”
The project initially developed by REG Power Management between the towns of Rhymney and Tredegar is expected to be finished by Christmas.
