Wylfa Newydd – About Our Site

The Wylfa Newydd site, on the Isle of Anglesey, is ideally situated for low carbon nuclear power production. As well as the vital infrastructure developed to support the existing station, Anglesey has a highly skilled nuclear workforce and direct access to essential seawater cooling facilities.

The site is on land beside the former Magnox Wylfa Power Station, which is now being decommissioned. It provides good foundation conditions for a new nuclear power station and is high above sea level to simplify the process of managing flood risks.

We aim to secure first electricity generation at Wylfa Newydd within the first half of the 2020s. This will follow extensive engagement with the local community.

Major project milestones
There are several key stages in the planning process before any construction can take place. To build a new nuclear power station a Development Consent Order (DCO) application must be submitted to The Planning Inspectorate. This process involves a significant period of consultation and can take several years to complete.

Following the acquisition of Horizon Nuclear Power by Hitachi, we plan to deliver two UK Advanced Boiling Water Reactors (UK ABWRs) – generating a minimum of 2,700MW at Wylfa Newydd.
