Summary of the contracting process

Orkney Islands Council procured balance-of-plant works for the Orkney Community Wind Farms. The awarded requirement covers the Quanterness wind farm on Mainland Orkney, north-west of Kirkwall. It involves design and construction of civil and electrical infrastructure ahead of wind turbine installation, including project and technical management, health and safety coordination, site facilities, permit control, site design, clearance and excavation, access roads, crane pads, turbine foundations, a substation building and installation, cable ducting, installation and commissioning. The contractor is also responsible for protecting installed items during construction, removing materials and equipment, and completing snagging and defects work. The buying organisation is Orkney Islands Council, with delivery on Mainland Orkney.

This procurement has reached award and contract stage for the Quanterness Wind Farm lot. It used a selective restricted procedure, with up to five candidates invited to the second stage; bids were submitted electronically in English, and variants were not allowed. The lot was evaluated on technical quality weighted at 40% and price at 60%. The lot’s estimated value was £7,000,000, while the active contract was signed on 24 August 2026 for £14,053,315.27. The award was made on 25 August 2026 to Heddle Construction Ltd. The contract duration is 720 days. Two bids were received, including one from an SME, and both were electronic. The supplier is undertaking subcontracting.

This award demonstrates demand from Orkney Islands Council for a substantial renewable-energy civil and electrical works package supporting onshore wind development. A credible future supplier would need to deliver integrated design-and-build construction ahead of turbine installation, including roads and crane pads, turbine foundations, substations, cable ducting and commissioning. It would also need strong project and technical management, health and safety coordination, permit control, site logistics, construction-phase protection and close-out of defects. Experience working in a remote island environment, coordinating multiple technical disciplines and maintaining site facilities would be commercially relevant. The competitive route favoured suppliers able to demonstrate technical quality as well as price, while the successful contractor’s subcontracting indicates that capable specialist partners may have a role in delivering similar packages for this buyer.
