Swiss utility, railway to meet builders for 600-MW Nant de Drance

A consortium of a Swiss utility and a federal railway invite civil works constructors to a September 25 informational meeting on the proposed 600-MW Nant de Drance pumped-storage project to be developed in the Swiss Alps.

Utility Aare-Tessin AG fur Elektrizitat (Atel) and federal railway SBB invited equipment suppliers to a similar meeting on the project in June. At that time, they said they planned to seek equipment tenders in the second half of 2006.

Atel and SBB now say they plan to initiate tendering for civil works in 2007. Civil contractors are invited to the advanced information meeting and site inspection of the project area between existing storage reservoirs of Emosson and Vieux Emosson in the Swiss Alps.

Nant de Drance is to include an underground powerhouse containing four 150-MW variable-speed pump-turbines, a transformer cavern with common access tunnel of 5,500 meters starting at Le Chatelard, two parallel water conveyance systems with 250-meter headrace tunnel, 470-meter vertical shaft, 160-meter steel-lined pressure tunnel with manifold, and tailrace tunnel with manifold.

Participation at the pre-information meeting is not a condition for later tendering.

Interested contractors are asked to notify the owner’s project manager by telephone or e-mail listed below by September 15. The meeting point September 25 will be at SBB’s existing 124-MW Chatelard hydro plant at Finhaut.
