The Mona Offshore Wind Project is a proposed offshore wind farm located in the east Irish Sea, being developed by Mona Offshore Wind Ltd, a joint venture of bp and Energie Baden-Württemberg AG (EnBW).

The Mona project includes offshore elements to generate electricity and both offshore and onshore elements to enable transmission of the electricity generated to the national grid:

  • Wind turbine generators (up to 107 turbines)
  • Offshore substation platform(s)
  • Offshore interconnector cables, inter-array cables and export cables
  • Transition joint bays (connecting the offshore and onshore cables)
  • Onshore cables
  • Onshore Substation
  • Connection into existing Bodelwyddan National Grid Substation

The Mona Offshore Wind Project is classed as a Nationally Significant Infrastructure Project (NSIP). This means that a development consent order (DCO) is needed from the Secretary of State for the Department for Energy Security and Net Zero.

Our statutory consultation on our latest proposals closed on 4 June 2023. We will now consider all the feedback we have received alongside carrying out further technical, engineering and environmental work.

Though our consultations have now closed, you can still find out more about the project and access consultation documents using the navigation panel above.

Who are EnBW and bp?

This project is being brought forward as a joint venture of bp and Energie Baden-Württemberg AG (EnBW).

About bp

bp's purpose is to reimagine energy for people and our planet.

bp has set out an ambition to be a net zero company by 2050, or sooner, and help the world get to net zero.

This strategy will see bp transform from an international oil company producing resources - to an integrated energy company providing solutions to customers.

bp already has a significant onshore wind business in the US with a gross generating capacity of 1.7GW, operating nine wind assets across the country as well as a 5.2GW net offshore pipeline.

About EnBW

Energie Baden-Württemberg AG (EnBW) is one of the largest energy supply companies in Germany and Europe,

with a workforce of 27,000 employees supplying energy to around 5.5 million customers. Installed renewable energy capacity will account for 50 percent of EnBW's generating portfolio by the end of 2025.

EnBW was among the pioneers in offshore wind power with its Baltic 1 wind farm in the Baltic Sea. EnBW has developed, constructed and operates four offshore wind farms in Germany with a total installed capacity of 945MW.

Another 960MW from the offshore wind farm He Dreiht are currently under development; the final investment decision in March 2023 cleared the way for the start of construction.
