Atlantis Resources has finished reinstalling the 1.5MW AR1500 turbine at Phase 1A of its MeyGen tidal stream project situated in the Pentland Firth, Scotland.
The Olympic Challenger vessel was used to install the turbine, which is the fourth and final unit of the project.
Atlantis has already commissioned the unit.
The reinstallation has enabled the MeyGen Phase 1A facility to operate at its full capacity of producing 6MW of power.
MeyGen Phase 1A has so far produced more than 2.6GWh of electricity, with more than 800MWh of energy sent to grid during last month.
After completing final testing, the MeyGen Phase 1A is set to formally end its construction phase and will enter its 25-year operational phase over the next few weeks.
Atlantis Resources CEO Tim Cornelius said: “The success of MeyGen, the world’s largest tidal stream project, firmly positions the UK as the leader of an industry which could provide sufficient affordable, secure, predictable and clean power to meet 20% of the UK’s future electricity need.
“We have asked the government to enter into a bilateral negotiation for 80MW of capacity, to allow us to proceed with the construction of Phase 1C of the MeyGen project without further delay.
“Tidal stream power costs are reducing all the time, with a strong trajectory towards achieving parity with established renewables such as offshore wind.”
Atlantis has currently been given approval to add up to 398MW of capacity into the entire MeyGen tidal stream project.
