Wylfa Newydd Construction Considerations

Wylfa Newydd
Access and ground work on this facility has already started. There are two or three aspects of this that may be of interest to the Club when anchoring in Cemaes Bay or sailing on the Menai Strait.
1. Blasting. As part of the construction of the new power station and the removal of redundant features of the old one, Horizon are seeking permission to "blast" between 1000 and 1600 Monday to Friday and 1000 to 1300 on a Saturday. There will be no blasting on Sundays and Bank Holidays. They also intend to crush rock on site and reuse this as part of the construction process. Be prepared for a bit of noise! It s not clear yet when this will begin.
2. Shipping movements. Horizon intend to reduce road traffic to the site by proposing to bring in between 60% and 80% of the bulk materials required by sea to a specially constructed "MOLF"(Marine Offloading Facility). Horizon are currently seeking permission for up to 16 vessel movements per day involving 8 vessels. This will vary on a day to day basis with no vessel movements on some days, and the maximum permitted on others. Presumably on days with a howling gale from N or NW, there will be no movements! As above the start date is undecided but will depend of course on the completion of the MOLF and breakwater next to the existing Wylfa outfall.
3. Horizon now plan to construct the new overhead lines from Wylfa to LlanfairPG roughly parallel and slightly to the west of the existing lines. However from a new substation near LlanfairPG to near the existing Pentir substation in Gwynedd the new lines will be in a tunnel under the Strait just NW of Plas Newydd. This does perhaps mean there will be no restriction to navigation on the Menai Strait during construction.
