Fish farmer orders second floating solar plant after summer of success
The diesel generator has barely been running, says Emilsen after first installation meets more than 90% of farm's needs
Just weeks after commissioning what is now the world's northernmost floating solar power plant, Norwegian salmon and trout farmer Emilsen Fisk is placing an order for a second system from Ålesund-based Alotta.
The solution - an Alotta Circle Mc120 - has already enabled Emilsen Fisk to cover over 90% of its power needs at its Båfjordstranda site, Trøndelag, by using only solar energy and battery storage.
“We were curious to see how solar power would perform in real conditions - and we got the answer quickly. The diesel generator has barely been running,” said Roy Emilsen, managing director of Emilsen Fisk, in a press release. “It's quiet at the site - in the best possible way. We’re saving money, reducing emissions, and improving the working environment. That’s why we’re now ordering system number two.”
Alotta develops and delivers green energy systems, with a strong focus on floating solar power. Designed for maritime conditions, the company's robust systems combine solar panels and batteries to supply reliable power directly to feed barges - without the need for grid connection or constant diesel use.
“This is a clear sign of the shift happening in aquaculture,” said Alotta chief executive Kari-Elin Hildre. “A new energy reality is emerging - in places where diesel used to rule, we now see quiet, renewable energy coming from solar and battery systems.
“When a customer like Emilsen Fisk orders a second installation after just a few weeks of operation, it’s not only about technology, it’s about trust, ambition, and a shared commitment to moving aquaculture into the future. Real change happens when technology and ambition align.”
Large government subsidy
The installations at Emilsen Fisk are partially funded through support from Enova, a Norwegian government agency that promotes the transition to sustainable energy. Enova covered 45% of the cost of the first system.
Alotta says this support is a key driver for change in the industry.
“These incentive programmes help more and more fish farmers take the leap - both those without shore power and those already using battery hybrids but wanting to go even greener with solar,” said Alotta’s chief sales officer, Egil Hjelmeland.
“We assist with the entire application process, making it easy for customers to get started.”
With the right system design, solar and battery can cover most of the power needs - and the diesel generator can remain idle

The right design
Alotta’s chief technology officer, Erik Rongved, is not surprised by the performance results at Emilsen Fisk.
“We see this time and time again: with the right system design, solar and battery can cover most of the power needs - and the diesel generator can remain idle. This leads to lower operating costs, less maintenance, and a better everyday experience for staff.”
The new plant will be delivered this autumn. It will initially be used at a different site to Båfjordstranda, then be moved there.
Still works in winter
The amount of daylight in Trøndelag varies between under five hours per day in January to more than 20 hours per day in mid summer. But even though Emilsen Fisk won’t nearly as much benefit from its solar plants in winter as it is getting now, there will still be power generated in the dark months.
“Thanks to major advancements in solar technology over the past few years, modern high-efficiency panels are capable of generating energy even under low-light conditions,” Egil Hjelmeland explained to Fish Farming Expert.
“So, while production is reduced in the darkest months, the system does not go completely offline and will still contribute useful power, especially on clear days.”
Alotta’s mission is to make a real difference and show that it is possible to reduce emissions while improving everyday life for people, nature, and the aquaculture industry, said Kari-Elin Hildre.
“When our customers come back for more, we know we're on the right track.”
