Three 735 kVA generator sets to protect Formentera’s electricity supply

In the event of an incident affecting these facilities, the absence of a backup system could put the electricity supply of the entire island at risk. This was the challenge addressed by this project at the Formentera substation.

Genesal Energy supplied and commissioned three 735 kVA generator sets equipped with Volvo Stage V engines and designed to operate in parallel with the mains.

The project involved a number of requirements that went beyond the usual specifications. The engines had to comply with Stage V emissions regulations, so we selected an engine capable of meeting these requirements. Due to the technical characteristics of the acoustic enclosure, a special AdBlue tank was also designed.

On the power output side, in addition to the standard power connection bars, we installed Powerlock connectors. The generator sets were also equipped with connectors enabling communication between the units should synchronisation be required.

The customer also required the units to be unloadable using a forklift truck. We therefore designed and calculated dedicated lifting systems allowing each generator set to be lifted from its lower section, simplifying both delivery logistics and any subsequent handling operations.

Each generator set is housed in a highly soundproofed 5,800 mm canopy with an upward air outlet. Its 1,200-litre base fuel tank provides 12 hours of autonomy at 75% load.

This project reflects the way we work: developing customised solutions that combine engineering, manufacturing and technical expertise to meet the specific requirements of every installation, particularly when the electricity supply of an entire territory is at stake.
