Commencement of the ITT process, which will continue until winter 2023, enables SSE Renewables to plan engagement with businesses across the Lochaber and Highland regions to highlight the local supply chain opportunities the project will bring. The construction phase of the project is scheduled to commence in spring 2024 and, is expected to support up to 500 jobs.
The tendering process will consist of two stages ahead of a final decision on whether to proceed with construction of the scheme in late 2023.
The return of tenders in April will complete the first stage. At this point one tenderer will be selected for the mechanical and electrical plant scope and two tenderers for the civil engineering scope. The selected tenderers will then progress to stage two, which is planned to run from July 2022 until autumn 2023, during which time extensive ground investigation works will be undertaken across the site. This work will enable the tenderers to refine their project designs.
The selection of the preferred civils tenderer, who will work with the chosen mechanical and electrical tenderer to construct Coire Glas on a turnkey basis, is scheduled for autumn 2023.
