In this episode, Sam Hollister is joined by Mark Williams, Senior Advisor in EDF’s Strategy & Policy Team, and Iris Shrestha, Lead Analyst in LCP Delta’s Power Modelling Team. 

We discuss:

• Why constraint costs are rising in the GB electricity system.
• What reformed national pricing could mean for market efficiency and investment.
• Practical ways the system could reduce constraint costs while supporting clean power. 

What’s one thing you would like listeners to take away from this?

• Constraint costs are not simply a by-product of renewables; they reflect how the system is planned and operated. With the right reforms and smarter use of the existing network, the UK can reduce costs for consumers while continuing to scale clean power. 

Any recommendations?
