Enel SpA is an Italian company operating in the generation and distribution of electricity and distribution of natural gas. Enel Brasil, established in 2005, is the largest private company in the electricity sector within Brazil, serving more than 7 million customers in the São Paulo metropolitan area.

The electrical substation in São Paolo’s densely inhabited Alphaville development was in critical need of a fire detection and suppression system. Both reliable operation and instant activation were critical to safeguard the surrounding residents and property. The site consisted of four transformers and one panel room, with each transformer housing consisting of 900m3 of volume. With very limited space and no extra power to feed an electrical pump, ENEL sought a compact fire protection solution that could operate independently from the property's electricity.

ENEL chose the HI-FOG® Gas Pump Unit (GPU). The GPU requires a significantly smaller water reservoir than a traditional sprinkler system, reducing total size sufficiently to meet ENEL’s space limitations. The GPU requires no electrical power to actuate and it discharges fine water mist. The system was the first of its kind to be deployed in an electrical substation in the country, and led directly to a revision to the state code for substations — cementing ENEL as a forerunner in the safe distribution of electricity within Brazil.
