French dams operator seeks command control upgrade for 9-MW Naussac Dam

Loire River dams owner Etablissement Public Loire (EPL) invites applications for pre-qualification to modernize the command control system of 9-MW Naussac Dam in France’s Loire River Basin. Responses are due September 11.

EPL took bids last year for operation and maintenance of 60-MW Villerest Dam on the Loire. It awarded a contract in 2007 to BRL Exploitation of France to operate and maintain the Naussac 1 and 2 small hydro and pumping stations.

The Naussac plants are used to prevent excessive seasonal flow variations in the Loire. When there is an excess of water in the tributary Allier River, the project’s generating units are used as pumps.

EPL invites pre-qualification by firms to modernize Naussac’s command control system to facilitate the operation of the dam by non-automation engineers. It seeks a reliable and user-friendly tool for the dam operator.

Tender documents may be obtained from the address below. Applications for pre-qualification are due by 5 p.m. September 11. EPL plans to invite bids from selected firms by October 1.
