Welcome

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

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

  • Wind turbine generators (up to 96 turbines)
  • Four offshore substation platforms
  • Offshore interconnector cables, inter-array cables and export cables
  • Four transition joint bays (connecting the offshore and onshore cables)
  • Onshore cables
  • Onshore substation
  • Connection into the 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) application has been submitted to the Secretary of State.

The Examination closed on 16 January 2025. There will now be a period of three months for the Examining Authority to write its report and make a recommendation to the Secretary of State. The Secretary of State will then have three months in which to make a decision.

About EnBW

EnBW is one of the largest energy supply companies in Germany and supplies electricity, gas, water and energy solutions and energy industry services to around 5.5 million customers with a workforce of more than 27,000 employees. EnBW aims to strengthen its position as a sustainable and innovative infrastructure partner for customers, citizens and local authorities to an even greater extent. The repositioning of EnBW with a focus on renewable energies and smart infrastructure solutions is a key component of its strategy. With a focus on renewable energy and smart infrastructure solutions, EnBW’s objective is for half of the electricity it supplies to be from renewable sources by the end of 2025. This is already having a noticeable effect on the reduction of CO2 emissions, which EnBW aims to halve by 2030 and to be climate neutral by 2035. EnBW has been involved in the operation of hydro power plants in the Black Forest for more than 100 years, and has a large and continuously growing number of onshore wind farms and solar photovoltaics in Germany, France and Sweden. In addition, EnBW developed, constructed and operates four offshore wind farms in Germany (EnBW Baltic 1, Baltic 2, Hohe See and Albatros) with a total installed capacity of 945 MW, commissioned between 2011 and 2020. A further 900 MW offshore wind farm, He Dreiht, is currently under development in Germany.
