Chris Stark is leading the UK's Clean Power 2030 mission. As Head of Mission Control at DESNZ, no one sees the constraint costs, grid bottlenecks and reform of National Pricing trade-offs more clearly.

The UK is building a clean power system at a pace not seen since the 1960s, connecting record volumes of wind and solar while transmission, storage and gas all reshape around them. Constraint costs have hit £1.7 billion, gas is being squeezed off the system, and the government has just rewritten the rules of the wholesale market.

Chris joins Ed Porter to break down what Mission Control is actually delivering, where flexibility and storage fit into the 2030 plan, and what Reformed National Pricing means for investors, generators and consumers.

They cover:

• Why building UK transmission lines takes 8-10 years — and why bringing two projects forward by a year is worth £4bn to consumers.
• Why the UK chose to build the grid and the generation simultaneously, and the risks that creates.
• Why the strategic spatial energy plan is the biggest energy decision coming in the next 12 months and how it sets up a "build it once" network for the future.
• The reform of National Pricing decision, what the wholesale CfD means in practice and how electricity is being de-linked from gas.
• Why flexibility is the "forgotten third child" of the energy transition and how dunkelflaute, long-duration storage and household batteries fit into the 2030s system.
• Chris's contrarian take on carbon pricing - why he thinks the Treasury's decision to remove the Carbon Price Support from gas signals carbon pricing is "coming down the list of things that matters.”
