Launched Another Technical Seminar
Arnstein Vesterdal, District Manager for Midt Norge.
“It was a successful technical seminar with many strong presentations. Among the participants were customers from grid companies, contractors, infrastructure (rail), Statnett and Statkraft. We brought ten suppliers from several segments that cover most of what you need in electrical distribution in medium-voltage networks,” says Sales & Marketing Manager at Møre Trafo, Ivar Lifjeld.
Wind Power
Wind power can be a controversial topic in Norway. In his presentation, Akershus Energi’s Henning B. Eriksen shared experiences and the wind farm’s contribution to society. Akershus Energi owns Odal Wind Farm together with Cloudberry and KLP. The wind farm in Nord-Odal municipality is a NOK 2.1 billion investment with a 30-year service life. It has been in full operation since 2022.
20 minutes – one year’s consumption
The plant consists of 34 Siemens Gamesa wind turbines with a rotor diameter of 145 meters and a height from foundation to blade tip of 217 meters. Power production starts at wind speeds of 3–4 meters per second, reaches maximum output at 11–15 m/s, and shuts down in strong winds – 25–28 m/s. When one of the turbines has been spinning for 20 minutes, it has produced enough electricity to cover one year of consumption in an average Norwegian household – 16,000 kWh.
The wind farm supports the green transition with an expected annual production of 530 GWh (33,000 households). It generates income for owners, landowners, suppliers, the municipality, and the state. In total, the municipality will receive around NOK 250 million in property tax over the lifetime of the plant.
Strong Presentations
To mention just a few of the many strong talks: Geir Saltkjel from Ulvesund Elektro presented the Lefdal Mine Datacenter in the mountain, and Christian Pedersen from Nukissiorfiit gave insight into the power supply in today’s Greenland and how challenging it is to run a utility on the world’s largest island, which Donald Trump is so eager to take over.
230 to 400 volts
REN, represented by electrician and power engineer Knut Eliassen, presented NEK 350, a standardized method for converting electrical installations from traditional 230 to 400 volts. The advantage of 400 volts is lower losses in the utility’s cables, and the cables can also be thinner. A homeowner notices little or no difference whether it is 230 or 400 volts.
— From the suppliers, Procab marked its 25th anniversary, where owner and CEO Rune Halvorsen served canapés and bubbles, and Schneider contributed with “Innovation in the Air”. Since the EU bans the use of SF6 gas from 2026, they now use “air” as the insulation medium in the breakers, Lifjeld says.
Good News
Lisbet Bråstad, Customer Service Møre Trafo, reports strong feedback once again on both the technical content and the social side. Møre Trafo’s Ole Linstad had the main responsibility for the program.
