Big opportunities in wind power

Wind power is growing rapidly, and at Holtab we play a part in delivering solutions to wind projects throughout the Nordic region. We offer products such as primary substations, compact secondary substations (CSS), switching stations and SCADA buildings, adapted to each customer’s unique needs.

Renewable energy sources

"Our knowledge is valuable to have early on in the journey"

The electrification wave in Sweden is underway at full speed and many companies are investing in developing renewable sources such as solar and wind power. With its extensive experience in the field, Holtab has valuable knowledge and acts as a link between the connecting companies and grid operators.

Power for sustainability

Wind power affects the environment very little and is a vital resource in reducing carbon dioxide emissions. Use of these renewable energy resources is also the most rapidly increasing worldwide. Nonetheless, the energy and environmental efficiency of the facilities must be optimal.

Smart technological solutions

We supply plants to wind farms all over the Nordic region. This involves customer-specific solutions with products such as primary substations, compact secondary substations (CSS), switching stations and SCADA buildings.
