Tidal energy operator Atlantis has agreed a £7.5M deal to add a further two turbines to the MeyGen scheme at Pentland Firth, Scotland.
The two-year contract has been signed with Energy Technologies Institute (ETI), which is funding the project.
Atlantis expects to start work on the MeyGen scheme later this year, after securing funding for the £51M scheme. It will be the world’s largest planned tidal stream energy project.
The new agreement will see another two 1.5MW tidal energy turbines installed on a foundation structure.
This will increase the number of turbines at the site from four to six and the rated capacity of the array from 6MW to 9MW.
When completed, the whole project will comprise up to 269 turbines on the seabed, generating enough energy for 175,000 homes in Scotland.
