Summary of the contracting process

Scottish Power UK PLC procured construction and civil engineering works for a 275kV cable duct system serving a single circuit with maximum capacity of 554MVA. The cable is to run between new terminations beside overhead-line tower YG001 at Longannet 275kV substation and the Devilla Battery Storage Facility substation. The requirement concerns electricity network infrastructure and associated construction works, primarily in the UK, with the possibility of work in other locations. The procurement also covered other electricity infrastructure requirements: refurbishment of a 132kV circuit breaker and 23 line isolators at Gateacre substation, a new 132kV connection from Kronospan Maersgwen Farm to Legacy and Oswestry substations, and a new 132kV circuit breaker with protection and control works for the Legacy 132kV Reinforcement project.

The procurement is complete and was run by selective negotiated procedure with a prior call for competition. The recorded awards are active. Excalon Limited and R.J. McLeod (Contractors) Limited were awarded contracts for the main requirement; further active awards are recorded for related electricity infrastructure projects, including Connahs Quay and Legacy reinforcement, Gateacre Phase 2 and Kronospan. The associated contracts were signed between 28 May 2025 and 27 July 2026, including contracts signed by Excalon on 28 May 2025 and by R.J. McLeod on 23 July 2025. The original Gateacre, Kronospan and Legacy lots are recorded as cancelled. Two bids were recorded for the main lot, with a further statistic recording one bid. Electronic auction techniques were used, and submissions were in English.

This procurement indicates demand from Scottish Power for contractors able to deliver high-voltage electricity network construction and civils, particularly cable duct systems supporting 275kV circuits and substation reinforcement at 132kV. Relevant suppliers would need practical capability in cable-route civils, substation construction, circuit-breaker installation, protection and control works, and connections between substations and generation or storage assets. Experience of working safely on live or high-voltage network environments, coordinating complex utility infrastructure and delivering large construction packages would strengthen a competitor’s position. Scottish Power’s supplier route begins with qualification through Go Supply, followed by registration with SAP Ariba and the Iberdrola IBuy tendering system. Suppliers should therefore be prepared for formal qualification, electronic tendering and English-language submissions.
