Naussac 2 : mise en œuvre des pompes turbines Deriaz
Naussac 2: using turbine pumps Deriaz
3 Alstom Hydro Turbines Neyrpic
EPALA, the owner, has entrusted Somival, the project manager, and Neyrpic with the construction of the hydroelectric part of the second phase of the Naussac installation, ensuring additional reservoir filling by pumping. The choice of Deriaz pump-turbines was fundamental to obtain the flexibility required for using the Allier water ressources. These machines are able to operate over a relatively wide range of flows and upstream loads and so adapt to the site's variable hydrological conditions.
The owner wanted to maintain the best possible quality of pumped water, which meant installing "green" machines with a number of innovations.
