Key Reference



Hydro-wind project: the final goal of which is ensuring that the entire island’s energy consumption comes from renewable energy sources.
To do so, a wind farm and a hydropower station were installed, connected with the current electrical system of El Hierro, property of UNELCO-ENDESA.

Extent of UNITECNO supply:

6 x 6″-600# minimum flow valves

  •  Nominal flow: 210 m3/h
  • Nominal height: 700 metros

2 x 10″-600# minimum flow valves

  • Nominal flow: 640 m3/h
 Nominal height: 700 metros

UNITECNO participated in the design and supply of minimum flow valves to protect the pumping system that collects water in an elevated reservoir as an energy storage system.
We would like to showcase this case study for its technological and environmental relevance.
