Offshore fish farming isn’t traditionally known for sustainability. The industry relies on burning a lot of diesel. 
One farm in Chile wanted to move towards a renewable solution and reduce the farm’s footprint. They decided on solar and covered the holding pens with panels. 
The main goal was to cut emissions but also to do away with the noise of the diesel generators. 
The efforts were a success, but they also attracted a new variable that engineers didn’t forsee. 
What drew thousands of unexpected residents to the new solar setup?
Fish farms built offshore need constant energy. Mowi’s Huar Norte salmon farm in the waters of Chile relied on diesel generators for years.
The engines were used to power everything, generating a scary amount of carbon emissions. 
But they also created a problem under the surface, resulting in noise, vibrations, and stress. It was relentless, and the fish and staff alike needed a break.
Mowi decided to act, teaming up with the AKVA group to build a cutting-edge solar pen system. The point was to slash fossil fuel reliance and clean up operations. Cutting out the noise was a bonus.
The results of installing panels on the water surface were immediately clear. A silence settled over the site in Los Lagos, and the underwater vibrations stopped.
It may have seemed tranquil, but there were changes happening below.
There was serious teamwork involved in the fish farm upgrade.
The resilient pens were built by the AKVA group. Alotta Energy was behind the floating solar grid, providing it as a service. 
Fjord Maritime came to the party with advanced battery storage packs to cover the power management.
The engineering is notably efficient, with the hybrid solar system now covering about 57% of the farm’s energy needs. This eliminates more than 36,000 gallons of diesel fuel each year. This is the equivalent of keeping 386 tons of carbon out of the atmosphere.
There are benefits for logistics, too, because fewer fuel delivery boats have to visit the site.
There are new shadows over the pens created by the solar arrays. It’s a large canopy that offers a form of protection.
Now, with the absence of the noise of the turbines and disturbance of the fuel delivery vessels, the farm is an ocean oasis. 
And it’s super attractive to wildlife from below. 
This technology is growing fast, with Alotta Energy already having tested their systems in Norwegian waters. They’re even behind the northernmost floating solar plant in the world.
In Chile, the workers are happy with the results of the upgrade. The site is cleaner and safer, and they can work in peace. Huge volumes of diesel fumes are a thing of the past. 
And one species of fish has discovered a new fortress for gathering.
It was salmon that decided to capitalize on the shade that the new panels provide. They’ve now claimed the space under the pens. The solar footprint is their new home.
The cleaner water also contributed to a more accepting environment.
But the protection and shelter from predatory birds and harsh sunlight were great drawcards for salmon. Cod have taken advantage of the same conditions in other parts of the world. 
The shade and cleaner habitat were just too good for the smart salmon to pass up. They’re thriving in a new environment we built by accident.
Innovation often helps the planet in ways we hadn’t expected. We might just build a better home for the wildlife around us by fixing heavy industry.
What other industrial spaces could become sanctuaries if we turn down the noise?
