Salmon farmers in Chile and Norway are pioneering a clean energy revolution by installing the country’s first-ever floating solar power plant at sea cages, signaling a significant step towards sustainable aquaculture.

In a close collaboration between Mowi Chile, AKVA Group, Fjord Maritime, and Alotta Energy Chile, the innovative floating solar system, powered by Alotta Circle technology, was recently deployed at Mowi’s salmon farm in Isla Huar, Los Lagos region, in Chile.

This hybrid renewable energy solution generates solar power directly on the sea surface and includes integrated battery storage to provide reliable, 24/7 energy. The system is set to cover around 50% of the site’s energy needs, drastically reducing diesel use, emissions, and the number of fuel-supply boat trips required.

AKVA Group Chile played a key role in the installation and ongoing maintenance, ensuring fish farmers receive predictable and affordable renewable energy from day one. This approach simplifies the transition from diesel, accelerating the shift towards cleaner operations.

“This is a moment of deep pride,” said Kari-Elin Hildre, CEO of Alotta Energy Chile. “The Alotta Circle is no longer just a Norwegian solution — it’s now part of Chile’s clean energy future. We’ve delivered a robust system ready to replace diesel even in demanding offshore conditions. Today, it’s real and effective where diesel once dominated. Thanks to everyone who made this possible. Let’s keep turning sunlight into impact.”

The project was made possible through the combined expertise of four Norwegian-rooted companies: Mowi Chile as the customer; AKVA Group handling cage infrastructure and operations; Fjord Maritime delivering energy storage solutions; and Alotta providing the floating solar technology and renewable energy supply through its Chilean subsidiary.

Following this success, Alotta Energy Chile has secured a second order from Emilsen Fisk to install a floating solar power system in Norway, further advancing sustainable aquaculture solutions internationally.
