Summary of the contracting process

SSE plc sought works to design, supply and install 400 kV gas-insulated switchgear (GIS) equipment at an existing substation. The requirement concerned transformer-substation works and was associated with the Blackhillock Battery project. Delivery was in the Moray area of Scotland. The scope covered the full engineering and installation package rather than equipment supply alone, so it was relevant to businesses able to take responsibility for design integration, high-voltage equipment, site installation and commissioning at an operational substation. The buyer was SSE plc, a major energy company based in Perth. The procurement was classified as works and focused on specialist electricity transmission or distribution infrastructure rather than general construction or standard electrical supplies.

The procurement concluded unsuccessfully. It comprised one lot, which was cancelled, and the associated award was also recorded as unsuccessful. The proposed route was a limited procedure using a framework call-off, specifically a direct award without prior publication of a call for competition. The stated rationale was the specialist scope: the works could be provided only by a particular economic operator for technical reasons, and the buyer also cited the absence of tenders or suitable requests in an earlier competitive procedure. The procurement was covered by the Government Procurement Agreement. No supplier was awarded the contract, no awarded value was recorded, and no contract period or award date was established.

This outcome identifies a specialist requirement for businesses operating in high-voltage grid infrastructure, particularly those with experience of 400 kV gas-insulated switchgear, substation design and installation. A credible future supplier would need to integrate equipment into an existing substation, manage complex engineering interfaces and deliver safely in an operational energy environment. Relevant capability is likely to include design authority responsibility, equipment manufacturing or specialist supply-chain access, installation management, testing and commissioning. Experience of framework call-offs and technically restricted procurement routes would also help a competitor understand how SSE may source this type of work. The cancelled lot and unsuccessful outcome show a specific, technically demanding requirement within SSE’s energy infrastructure programme, rather than a general electrical construction opportunity.
