Brisk progress is being made on preparatory works at Brenig wind farm.
All the access tracks and crane pads have been constructed, and the earthworks for foundations completed one month ahead of schedule, at the mid Wales site, where Jones Bros set up operations in September.
The 16-turbine scheme is the first to be built from scratch in the UK by Chinese developer, CGNEE.
The first turbine foundation has also now been completed. Each base requires 500 cubic metres of concrete, as well as 48 tonnes of reinforcing steel.
A workforce of 40 is now operating from the site. Jones Bros is also going to carry out on-site cabling works and construct a control building for the scheme.
Work will continue throughout the winter, weather permitting, with the bulk of the infrastructure due to be completed by April 2018. Turbines will be delivered during the summer, ready for a scheduled completion date in September 2018.
Once complete, the 37.6MW development will have the capacity to power more than 25,000 UK homes.
Prior to its current contract, Jones Bros had previously carried out early preparatory works to construct access roads, as well as harvest and export trees.
Jones Bros project manager, Eryl Roberts, said: “The earthworks have gone really well. The team is one month ahead of the programme in this respect, and our main target is to have all the earthworks completed by the end of 2017.”
CGN Energy Europe project manager, Romain Pelissier said: “Significant progresses have been made on site over the last two months.
“The prompt and massive mobilisations of Jones Bros resources have been very supportive. Our expectations are the turbine foundations concreting to be completed before Christmas.”
