Building and operating an electric society with competence and technology

Electric power

We plan, build, and operate electrical high and low-voltage systems. This includes the construction, operation, and maintenance of transformer substations, lines, and cables at voltage levels up to and including 420 kV.

We also provide operation and maintenance services. We are on-call whenever something goes wrong. We have repeatedly proven our ability to handle situations with major fallouts due to extreme weather conditions or natural disasters.

We work all over Norway, but we consider Southern Norway our stronghold.


We plan, build, and operate complete electrical infrastructure for roads, tunnels, and railways.

Smarter roads are safer roads. Otera helps develop and build state-of-the-art roads and rails with technical solutions designed to protect human lives. Otera offers security solutions that promote a good environment, safety, and cost-efficiency.

Otera designs, supplies, assembles, and maintains all types of lighting systems. We also provide infrastructures such as cameras, fiber communication to operational centres, climate stations, and gas detection. This enhances road safety and socio-economic profitability.


Otera is a company where employees should be as healthy when they go home, as they were when they came to work. Our HSE slogan Every Employee Safe Home underlines this. We cannot accept that our employees are injured while at work.

A job should always be performed efficiently and profitably, but this is always trumped by safety. Otera strives to ensure that employees think of preventive safety in all their work tasks.
