The Hammerfest Strøm tidal project was installed in Kvalsund in Finnmark county, Norway, at a 50m depth in the sound between Kvalsund and Kvaløya. The HS300 horizontal axis turbine device was installed in 2003, and grid connected in 2004 which made it the world's first tidal turbine delivering to the grid. The device rotated at 7 rpm with an installed capacity of 0.3 MW.
The device is installed at 50m depth in Kvalsund, Finnmark, Norway.
The HS300 device was installed at site in 2003, and became the world’s first tidal turbine of its kind to deliver electricity to grid in 2004. It was designed for a 3 years test period, and was retrieved after about 4 years of testing. All general components were in good shape, and the turbine was reinstalled in 2009 for further testing which was completed in 2011. The tidal turbine was retrieved in 2012.
The HS300 prototype was in operation for more than 17,000 hours, delivering over 1.5 GWh to the grid and showed 98% availability during testing, proving the device to be efficient and reliable.
The HS300 formed the basis of Andritz Hydro’s pre-commercial 1 MW HS1000 turbine technology, which was installed at the European Marine Energy Centre (EMEC) and delivered its first energy to the grid in February 2012.
Based on the learning gained during its testing period at EMEC, Andritz Hydro Hammerfest has developed 1.5 MW MK1 turbines, three of which have been installed as part of the MeyGen project in the Pentland Firth.
Hammerfest Strøm AS holds the consent to the site, given by the Norwegian Water Resource and Energy Directorate (NVE) for a 25 years period from 2001-2026. The trading license, hold by Hammerfest Strøm AS, was given in 2002 and need to be renewed every 4th year. The grid owner in the installation area is Hammerfest Energi AS.
A third party has been involved in the project since 2001. The chosen contractor has done several studies in the area earlier and has good knowledge of the location. The first study of the site was undertaken in 2001, before the prototype was installed at the site. The Company engaged the contractor to evaluate the site a second time when the HS300 turbine was retrieved for verification and again when it was redeployed at the site.
The EIA covered the potential impact the tidal turbine has on the business activities, outdoor life, marine life and seabirds, where it among other tests has been done a noise measurement. The EIA concluded that the HS300 turbine has no or insignificant impact on the studied areas.
