Case Study: Mona Offshore Wind Project

The project:

The Mona Offshore Wind Project is a consented wind farm in the Irish Sea off the north coast of Wales and northwest coast of England. 

It will include up to 96 turbines, generating around 1.5GW of electricity, four offshore substation platforms, offshore and onshore cables, with an onshore substation connecting into the National Grid. 

As a Nationally Significant Infrastructure Project (NSIP), a Development Consent Order (DCO) was required.

The client:

JeraNex bp formally bpEnBW 

Our role:e: 

As with all NSIPs, a DCO was required to seek planning permission to construct and operate the Mona wind farm. Pippa was the DCO Coordinator and Examination Lead working closely with consents, legal and environmental teams to prepare the DCO submission.  

Her role was central through the examination, working closely with multi-disciplinary colleagues across bpEnBW.  

This included: 

• Liaising with experts across all environmental disciplines, engineers, lawyers, consent leads, communications and other functions to prepare all DCO submissions 

• Reviewing and managing the response process for relevant representations, written submissions and Examination Authority questions 

• Ensuring that all public facing submissions were translated into Welsh, in line with the Welsh Language Act  

• Working with land agents to coordinate the accompanied site inspection 

• Leading the management of the public hearings working with external agencies including the Planning Inspectorate, to deliver successful events at different venues across North Wales 

Challenges:

The DCO Examination process is complex, with a series of deadlines that demand huge amounts of information to be quickly and accurately produced and submitted.   

Pippa’s role was to lead the team in gathering and reviewing all documentation, liaising with experts from across bpEnBW to ensure absolute accuracy and compliance with the Planning Act 2008, ultimately ensuring the process stays on track with the Examination deadlines. This role required in-depth understanding of the process, the project, attention to detail, effective relationship building and leadership skills. 

“MONA was our first big project as C3 Communications and, in July 2025 we heard the great news that it had been consented, making all the hard work worthwhile!  

“I thoroughly enjoy working on big infrastructure projects and, with Mona, I was able to bring both my experience of the DCO process and working on major projects in Wales.  

“To have been a key member of the team that saw this project successfully through the process to Secretary of State sign-off gives me a feeling of huge satisfaction.”
