IN Brief:
- RES has secured a five-year operations and maintenance contract with ScottishPower Renewables.
- The agreement covers 15 UK onshore wind farms with a combined capacity of 588MW.
- A Bellshill logistics hub will support maintenance, component refurbishment, and specialist resource planning.
RES has secured a five-year operations and maintenance contract with ScottishPower Renewables covering 15 onshore wind farms across the UK.
The portfolio has a combined capacity of 588MW, enough to supply electricity equivalent to around 412,000 homes each year. The contract includes planned preventative maintenance, corrective maintenance, and minor component replacement across the wind farms.
Delivery will be supported through a new RES logistics hub in Bellshill, Scotland. The hub will provide logistics, component refurbishment, specialist resources, and operational support for the contract. RES expects the agreement to create 32 roles, including 16 technician positions, with almost 100 people involved in the wider delivery model.
Major operational assets within the portfolio include the 136MW Harestanes wind farm in Dumfries and Galloway. Across sites of that scale, operations and maintenance activity is directly linked to generation availability, safety performance, component life, and long-term asset value.
Installed renewable capacity only contributes to the electricity system when it is operating reliably. Onshore wind farms already connected to the grid provide established low-carbon generation, and their output depends on maintenance quality, spare-parts availability, access planning, fault response, and the condition of electrical and mechanical systems.
The Bellshill hub points to a more industrialised model of wind operations. Local logistics and component refurbishment can shorten downtime, reduce reliance on distant supply chains, and improve response times during fault events. That approach becomes more valuable as turbine fleets age and operators seek to extend asset life while maintaining output.
Technical labour is also becoming a constraint across the renewable sector. Technician availability, high-voltage competence, blade inspection, component handling, remote monitoring, and specialist repair capability are all being stretched as wind, solar, and storage portfolios expand. O&M contracts now have to secure people, facilities, spares, and data systems as much as scheduled service visits.
Operational wind assets are also being assessed alongside flexibility and storage opportunities. In Sweden, the pairing of wind generation with co-located battery storage shows how existing renewable sites can become more active participants in grid management and energy markets.
O&M strategy will influence repowering decisions across the UK fleet. As older turbines approach the end of their original design life, operators must choose between continued maintenance, partial life extension, component upgrades, or full repowering. Each option depends on planning, grid connection, turbine condition, and the economics of continued operation.
In parts of the UK, onshore wind development remains constrained by planning policy and local acceptance. That places additional value on the performance of the existing operational fleet. Keeping connected assets available supports renewable output while new-build policy, grid reform, and repowering routes continue to evolve.
RES’s contract with ScottishPower Renewables reinforces the role of long-term service capability in renewable generation. New projects expand capacity, but maintenance infrastructure, component refurbishment, and skilled technicians determine how much of that capacity remains available year after year.
