An institutional infrastructure fund appointed Atharra to deliver the full technical and commercial scope required to implement aerodynamic blade upgrades on an onshore wind farm in Wales. Acting on behalf of the client, Atharra led the development phase, working closely with Anakata to refine, validate, and finalise the upgrade pack design before progressing into delivery.
To maximise the effectiveness of the installation campaign, Atharra coordinated drone-based blade inspections ahead of mobilisation, reviewed the findings, and defined a clear repair scope, managing these repairs alongside the upgrade works. Our scope covered engineering assessment, contracting strategy, tender management and supplier selection, installation project management, and performance validation. This end-to-end approach ensured the upgrades were engineered correctly, commercially protected, and installed safely within a narrow seasonal window.
End-to-end engineering, commercial, and delivery management
Custom aerodynamic packs refined, authorised, and installed
Two-team contracting model enabling a 9-week delivery window
LIDAR-based performance validation confirming uplift
From engineering due diligence to contracting, installation, and validation of aerodynamic upgrades
Atharra combined practical engineering expertise with structured programme delivery to manage all aspects of the upgrade rollout. We developed the engineering change assessment, validated structural integrity, led the contracting and commercial strategy, and managed installation risks including weather, access methods, turbine isolations, and quality assurance. To support performance verification, we designed and oversaw a LIDAR-based power performance validation process. This end-to-end approach gave the investor confidence that the upgrades were technically robust, commercially protected, and executed to a standard that delivers measurable performance improvements.
