GE Vernova has been given the green light to build an up to 18MW prototype offshore wind turbine that would be one of the most powerful ever produced by a Western manufacturer.

US manufacturing giant GE Vernova has signalled that offshore wind is not a sector that it is currently interested in, as it works its way through an unprofitable and occasionally bruising backlog for its turbines at sea.

But Georgine Wind, a Norwegian subsidiary of GE Vernova, has now secured permission to build an up-to 18MW turbine in the Nordic country.

The Norwegian Water Resources and Energy Directorate, NVE, announced today that it has granted Georgine Wind permission to set up the turbine in an industrial area in Gulen municipality on the country’s westernmost tip.

NVE said the Gulavind wind farm test project, as it is known, aims to further technology development for offshore wind.

Gulavind will consist of a turbine with an expected annual electricity production of 55GWh, said NVE – the annual energy consumption of around 2,750 Norwegian households. 

This is the largest wind turbine to be licensed in Norway, said Ann Myhrer Østenby, section manager at NVE. The turbine may stretch up to 275 metres in height; and up to 250 metres in rotor diameter.

It is unclear whether GE Vernova, which was approached for comment, really intends to build an 18MW turbine. Recharge reported last year that the OEM is aiming to install a prototype of its next-generation 15.5MW Haliade-X offshore wind turbine after securing Nkr332m ($31m) from a government-backed agency.
GE Vernova previously said it was axing plans to build an 18MW model, causing havoc for several projects in the US that had been counting on using them.

Current versions of the Haliade-X with ratings of 12-14MW are being deployed at major projects off the UK and US, including at the 3.6GW Dogger Bank site in the British North Sea.

Whether 15.5MW or 18MW, the turbine would potentially become the second most powerful in Europe upon installation – behind only Siemens Gamesa’s 21.5MW prototype installed this year in Denmark.
That is currently the world’s most powerful installed wind turbine, with two Chinese manufacturers – Mingyang and CRRC – having installed 20MW prototypes with varying degrees of success.
