Since investment needs for hub-and-spokes concepts are high, traditional CBA approaches bear the risk of negative evaluation with the potential to favour radial offshore wind deployment and hinder optimal future grid buildout for power and hydrogen. In this discussion paper, we summarize our experience at the North Sea Wind Power Hub, and make recommendations for working with CBA analyses of hub-and-spokes concepts.

A study to highlight challenges regarding balancing of offshore energy hubs under the offshore bidding zone market setup

Risks and mitigation measures associated with offshore bidding zones for offshore wind farm and power-to-gas developers

The North Sea Wind Power Hub (NSWPH) consortium is responsible for planning and pre-developing a series of hub-and-spoke projects that will enable large-scale North Sea offshore wind deployment and its integration in the energy system.

The hub-and-spoke concept offers a solution to the challenge of integrating offshore renewable energy to onshore energy systems in a cost-efficient manner, assuring further interconnectivity and security of energy supplies.

For a hub-and-spoke project, the economic and financial framework should be determined before the final investment decision and provide clarity on all financial streams and economic corner stones of support, cost recovery and financing mechanisms.

The aim of the first Pathway study was to learn how the integration of large-scale offshore wind is done effectively and in ways that maximises long-term socio-economic welfare while ensuring security of supply.

In this publication, we share five key insights that we believe will be crucial to unlocking the true potential of the North Sea.
