Description

Expressions of interest are sought from globally experienced pump storage power station designers and construction execution companies & consortia who have proven capabilities to deliver a new build 600MW Pumped Storage Hydro Project in Scotland, UK. Geotechnical investigations commence from Q4 2022 in support of a FEED study and eventual detailed design works. The construction phase starts in Q4 2025. Project Description; The physical construction works include the construction of a new intake structure within an operational upper reservoir connected via new hydraulic tunnel systems to the powerhouse complex excavated in quartz dolorite rock 400m below ground level. The powerhouse will be a series of underground caverns containing reversible pump-turbines, motor-generators and associated equipment including transformers and switchgear. A new tailrace tunnel will be constructed from the powerhouse to a new outfall structure in an existing lower reservoir. A vertical ventilation shaft from the powerhouse will connect through to an expanded existing above ground sub-station complex. A new 1.45km main access tunnel will link the powerhouse to a new jetty constructed along the lower reservoir. Forming the main access tunnel portal will require the diversion of a trunk road. The construction spoil is planned to be taken out through the mountain to the jetty and stored prior to off-site removal. New administration and workshop buildings will be built on the jetty. Existing access roads will be upgraded together with the construction of new roads as required.
