Gas Natural Fenosa Hydro Plants, Spain

Gas Natural Fenosa (GNF) is one of the main power (generation and distribution) players in Spain, with two hydraulic generation plants by the Miño River, which is located in Ourense (Galicia).
In each plant there is a power indoor trafo 132kV/6kV – 25MVA with switchgear. These types of trafos contain up to 17,000 liters of mineral oil, meaning the fires that occur within them generate a huge amount of heat. HI-FOG®, due to its cooling effect and radiant heat blocking, is therefore an optimal fire fighting system for this most unique challenge.
In both plants, a GPU was installed. This pumping unit delivers the flow rate and pressure needed, but uses a gas-driven pump rather than an electric power supply in order to function.
