PLANS for the Coire Glas hydro pumped storage scheme have taken a step forward with the receipt of tenders for the project’s main construction works.
SSE Renewables has shortlisted six tenderers to conduct the civil engineering and mechanical engineering works on the project, which will see the first large-scale hydro pumped storage scheme built in the UK for more than 30 years.
The firm said reviews of the tenders are now underway, following which it is anticipated a preferred tenderer will be selected for the mechanical and electrical scope and two tenderers will be selected for the civil engineering scope.
The preferred tenderers will work with the Coire Glas team on a programme of ‘extensive’ ground investigation works, running from July 2022 to autumn 2023, which will allow them to refine their proposed 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. The construction phase of the project is scheduled to start in spring 2024 and is expected to support up to 500 jobs.
The six tenderers shortlisted for the main construction works are:
- Bechtel Ltd., Acciona Construcción S.A. and Webuild S.p.A consortium
- BAM Nuttall Ltd, Eiffage Génie Civil SA and Marti Tunnel AG consortium
- Dragados S.A and BeMo Tunnelling UK Ltd consortium
- STRABAG UK Ltd
Mechanical and electrical plant:
- ANDRITZ HYDRO GmbH and Voith Hydro GmbH & Co KG partnership
- GE Hydro France
Ian Innes, project director for Coire Glas, said, “Receiving the tenders on schedule from the six short-listed tenderers is another significant milestone for the Coire Glas project and we are grateful for their continued interest in the project. We are encouraged by the content of the tenders which now provides the Coire Glas project team with several options on how construction of the project could be undertaken.
“It is going to take some time to carefully consider and scrutinise the tenders thoroughly and we look forward to working with the tenderers as we endeavour to make our selection decision.”
