On Monday SSE's transmission arm, Scottish Hydro Electric (SHE) Transmission, announced it had awarded four contracts with a cumulative value of around £600 million for new electricity substations in the north of Scotland.
The contracts were awarded to several joint ventures — ABB UK and Balfour Beatty Engineering Services; Alstom Grid UK and Enterprise and BAM Nutall and Siemens — and Miller Quatro, a consortium comprising Miller Construction and three Spanish companies – Sacyr Industrial, Isastur and Aditel, known collectively as Quatro T & D.
The BAM Nuttall and Siemens joint venture yesterday revealed that its contract for Moray and the West will total £200 million, representing a third of the capital expenditure in the framework.
The framework is part of £1.1 billion system reinforcement by SHE Transmission to accommodate further onshore wind, new offshore wind and emerging marine-generation developments, a key element of Scotland's low carbon ambition.
The framework is for five years with the facility to extend for an additional four years. The initial order value is up to £200 million.
BAM Nuttall and Siemens' award for Lot 3 (Moray and the West) includes five new substations. The joint venture is responsible for the entire scope including the design, manufacture, construction and commissioning of the new assets incorporating site access, platform construction, foundations and both gas-insulated switchgear (GIS) and air-insulated switchgear (AIS) substations.
The award builds on an already successful partnership between Siemens and BAM following the successful completion of the Britned Convertor Station in Kent in 2009.
Siemens and BAM are currently developing solutions for early stages in the programme with construction expected to start later in 2013 and continue through until 2018.
