Uskmouth
The Welsh Government 'called in' the planning application at Uskmouth in March 2021. The planning application related to fuel storage, material handling and other ancillary infrastructure to be constructed external to the existing power station building. As a result, the application will now be determined by the Welsh Minister and not the local Council.
Tidal
Atlantis continues to work with UK Government to secure the necessary support mechanisms to allow the further rollout of tidal stream technology, especially the next phase of the MeyGen project.
UK government changes to the UK CfD renewable energy support scheme announced in December of last year creates an opportunity for tidal energy to compete against floating offshore wind. The next auction (Allocation Round 4), which is due in the second half of 2021, will see a separate auction “pot” for tidal energy and floating offshore wind. Tidal previously competed with better developed normal offshore wind, where costs have dropped substantially, making it hard for newer tidal technology to realistically compete.
The new CfD arrangements could give Atlantis a chance to add capacity at its existing MeyGen tidal project which has already exported 35GWh to the grid.
MeyGen has a seabed lease allowing for up to 398MW of tidal capacity with currently 73.5MW fully consented and with grid capacity.
Atlantis’ second generation turbine, with an increased rotor diameter and lower weight foundations has already lowered costs. A proposed subsea hub could also reduce connection costs and on-vessel servicing will also to reduce operating costs further.
Once operational, this project will be the largest tidal array ever built and continues to be both a pioneer and a flagship for both the industry and the technology globally. The UK Government has indicated that it will announce the details of the support mechanisms this summer, with the auction round taking place towards the end of the year.
Operationally, MeyGen continues to provide vital learning to help the design and development for future projects. Currently, three of the MeyGen turbines have been moved to Atlantis’ workshop in Nigg to allow the team to complete onshore service works. One of the turbines is expected to be returned to service very shortly with the other two scheduled to be returned to service later in the year, once their service works are completed.
Project development for the group’s Raz Blanchard demonstration array, located between Alderney and France, is also making good progress.
Hydro
Atlantis is currently managing the construction of three interlinked hydro projects, with a combined total installed capacity of 5.8MW. The first project was commissioned in March 2021, with the second and third projects due to be commissioned this year
