Collaboration in the North Sea Powerhouse (Part 2)


Regulatory Challenges and Opportunities

Video & Selected Presentations



The development of renewables in the North Sea is critical for accelerating clean transition and boosting energy security for the UK and our European neighbours. Offshore wind in North Sea is set to play a key role to reduce dependence on natural gas and cut carbon emissions.  The UK government plans to increase capacity of offshore wind production to 50 gigawatts by the end of the decade and aims for the economy to produce net-zero emissions by 2050.

This was the second Webinar as part of the sequence Collaboration in the North Sea Powerhouse, “Regulatory challenges and opportunities” organised by CIGRE Women in Energy. Dr. Biljana Stojkovska, CIGRE UK’s Women in Energy Chair welcomed partcipants and led the panel discussion.  Mark Waldron, Chair of CIGRE UK, provided his summary for the event and the importance of CIGRE’s engagement.


  • The keynote speaker Rebecca Barnett, Interim Director Networks from Ofgem put the spotlight on importance of network regulation, anticipatory development onshore in readiness for offshore connections, network delivery pace and recommendations for future frameworks.
  • Serginio Remmelzwaal, Head of Electricity Interconnection & Future International Projects, from Department for Energy Security and Net Zero (DESNZ) presented the major challenges with delivering new transmission infrastructure and how technology can accelerate the pace of renewable energy development.
  • Lucy Morton Global Practice Leader, Environment from Mott MacDonald focused on aspects of changing environmental policy and legislation, potential impact and consequences of those on network and offshore wind design, construction and operation.
  • Amanda May, Group Engineering Policy Manager from National Grid provided insight how current regulations impacts building the network infrastructure and which are the future engineering aspects required to be taken into the consideration

Decarbonising the Power System by 2035- Challenge and opportunity

  • Guest panellist Runa Andersson Haave Project Offtake Manager from Statkraft, Norway provided an overview on Offshore wind emerging market in Norway and impact of network regulation

Offshore emerging market: Norway and the North Sea

  • The panel concluded with a presentation from Peter Weinreich-Jensen Managing Director Siemens Energy Denmark, on the World’s First Energy Island Concept in North Sea

The World’s First Energy Island Concept

The sequence will be continued with the event on Energy Security, organized by the CIGRE Germany on the 10th of October.




Rebecca Barnett

Rebecca joined Ofgem in 2012 and is currently Director of Networks, responsible for the economic regulation of Great Britain’s energy networks and development of RAB based models for new nuclear and CCUS transport and storage. As a Deputy Director she has led Ofgem’s work relating to the offshore transmission regime, offshore coordination, delivery of interconnectors, introducing competition to onshore networks, development of new regulatory models for supporting low carbon infrastructure (e.g. nuclear and carbon capture and storage). Last year she also set up our review of the financial resilience and controls of suppliers. Prior to joining Ofgem, Rebecca spent 10 years at Herbert Smith in their energy and infrastructure practice.
