Backup power to preserve marine life: we designed a generator set for a fish farm prepared for a marine environment

Genesal Energy has developed a tailor-made power solution for a fish farm located in the Atlantic Coast of Northwest Spain, an area especially exposed to corrosion issues.

The project involved the design and manufacture of a 440 kVA genset operating in parallel with two existing generators, ensuring production continuity even in the event of grid failures or instability.

Fish farms require a constant and reliable power supply to run essential systems such as water pumps, aerators, recirculators and sensors. A power outage can reduce oxygen levels in the water and suffocate the fish within hours, with severe economic and environmental consequences.

A highly demanding environment

The coastal location posed an additional challenge in terms of resistance and durability. Genesal Energy engineering department designed an open generator protected by an ISO12944-C5 anti-corrosion coating, ideal for harsh marine environments. The alternator was also marinised and fitted with anti-condensation heaters, increasing its resistance to humidity and salinity.

The solution includes an integrated 350-litre fuel tank providing up to 4 hours of autonomy, and a rubber anti-vibration system to protect the structure against mechanical vibrations.

Synchronisation and full control

The key to the project was to ensure seamless operation alongside the two existing units. To achieve this, a ComAp InteliLite AMF 25 IL4 control panel was integrated, enabling the load distribution management and remote control of the installation. Specific safety features such as emergency stop buttons and guards for hot and moving parts were also added, meeting the required safety standards.

Thanks to this bespoke design, the fish farm now benefits from a robust, efficient backup system ready to operate under extreme weather and environmental conditions, ensuring not only production continuity but also the survival of thousands of fish in the event of an energy emergency.
