A salmon farm in Chile has successfully transitioned to a hybrid energy model, replacing noisy, high-emission diesel generators with a floating solar array. By installing solar modules over its holding pens, the Mowi Huar Norte site has significantly reduced its environmental impact, cutting annual diesel consumption by over 36,000 gallons and preventing 386 tons of CO2 emissions. Beyond the operational efficiency, the installation has inadvertently created a sanctuary for local salmon, which have flocked to the shaded, quiet environment beneath the panels, demonstrating how renewable energy upgrades can foster unexpected ecological benefits for marine life.
The project, a collaboration between Mowi, the AKVA group, Alotta Energy, and Fjord Maritime, utilizes a sophisticated hybrid system that now supplies approximately 57% of the farm’s total energy requirements. By integrating advanced battery storage and solar technology, the facility has eliminated the constant vibrations and noise pollution previously caused by diesel engines. This shift has not only improved working conditions for staff but has also reduced the logistical burden of frequent fuel delivery vessels, further minimizing the site’s overall footprint in the Los Lagos region.
The transformation of the water surface has created a unique habitat for the salmon. The solar canopy provides essential shade and protection from harsh sunlight and predatory birds, while the removal of industrial noise and fuel-related disturbances has fostered a cleaner, more stable environment. This phenomenon mirrors similar observations in other parts of the world, where fish species like cod have also gravitated toward the shelter provided by floating solar infrastructure. As this technology expands, with Alotta Energy already operating systems in waters as far north as Norway, the project serves as a compelling example of how industrial decarbonization can simultaneously support wildlife.
