Providing emergency power in extreme weather conditions for the salmon industry in Norway

• HIMOINSA supplied over 3 MW of backup power via 2 x 2,000 kVA generator sets to a salmon smoltification facility in remote northern Norway, ensuring operational continuity.

• The solution includes redundancy and space-optimized integration tailored to the facility's critical need for uninterrupted power to maintain water quality and other vital processes.

• AS14 control panels provide a turnkey system that simplifies operation and integrates seamlessly with the plant's electrical infrastructure.

• The installation is engineered for Arctic conditions, featuring a hot air recirculation system to maintain room temperature despite extreme cold and strong winds.

HIMOINSA supplies backup power for onshore salmon smoltification facilities located in Laksefjord, Finnmark, one of Norway’s northernmost regions. The project, developed in collaboration with its dealer Akselsen Engineering AS, addresses the needs of industrial applications where uninterrupted power supply is critical to maintaining the stability of the production process.

HIMOINSA has extensive experience in supplying power to the salmon industry, both in Europe and Latin America, with gas and diesel power solutions. On this occasion, it has installed over 3 MW of power using generator sets configured to operate in a facility with redundancy requirements, space constraints and extreme weather conditions. Operation in a remote location in northern Norway, subject to low temperatures and strong winds during the winter months, demands an electrical infrastructure capable of guaranteeing availability, proper performance and suitable integration into the plant room.

Critical application for land-based aquaculture

The project is in Laksefjord, Finnmark, in the northernmost part of Norway, a region characterised by its Arctic environment, low population density and strong links to coastal and fishing activities. This geographical context influences both the project planning and the technical configuration of the facility, particularly due to the distance from major logistics hubs and the harsh environmental conditions.

The facility is dedicated to the smoltification of salmon on land, a key phase in the aquaculture production cycle. During this process, the young salmon undergo the physiological transition that allows them to move from fresh water to salt water, which requires maintaining stable and controlled parameters. In this type of facility, uninterrupted power supply is essential for systems related to water quality, oxygenation, temperature control, pumping and the general operation of the plant.

Redundancy and integration of the units within an optimised space

The technical specifications of the project called for a solution capable of ensuring redundancy and backup capacity, whilst maintaining efficient integration within a limited space. The 2 x 2,000 kVA configuration was tailored to the facility’s operational continuity requirements and the physical constraints of the plant room. 

In land-based aquaculture applications, where the continuous operation of auxiliary systems is essential for the stability of the production process, the backup architecture must be designed with availability, reliability and ease of operation in mind.

Control System | Turnkey Solution

The scope of the project includes a turnkey solution with AS14 control panels, tailored to the specific requirements of the facility. This control architecture helps to simplify system operation and facilitate its integration into the client’s electrical infrastructure. 

At an operational level, the solution is designed to meet the needs of an industrial plant where prolonged interruptions are not an option. The availability of a backup power supply ensures that the facility’s critical systems remain active, safeguarding the continuity of the smelting process and reducing the risk associated with failures in the main supply.

Designed to operate in arctic conditions and remote industrial environments

One of the main challenges is the remote location of the facility. The distance, the climate and the operational window constrained by winter mean that logistical and technical planning is a key factor in the success of the installation.

From October to May, the area experiences extremely low temperatures and strong winds, conditions that can affect both the performance of the equipment and the thermal stability of the room where the generator sets are installed. To address this environment, the installation incorporates a hot air recirculation system that modulates the air intake louvers and bypass louvers, maintaining the room temperature within nominal operating conditions.

With this project, HIMOINSA reinforces its ability to develop energy solutions in industrial environments where operational continuity is an essential requirement. The combination of industrial generator sets, an optimised configuration for the technical room, adapted control systems and preparation for extreme weather conditions enables the company to meet the demands of a land-based aquaculture facility located in one of the most remote regions of northern Europe.
