About this Episode
Gerard and Laurent have the pleasure of welcoming Fintan Slye, CEO of NESO — Great Britain’s National Energy System Operator.
In a lively and wide-ranging discussion, we explored NESO’s governance and its critical role across the British energy system: from real-time system operation — balancing supply and demand every second — to whole-system planning, market design, and transmission network operation.
We covered an extraordinary breadth of topics: balancing costs, electricity prices for consumers, energy security, and the challenge of delivering Power 2030 in a system increasingly reliant on renewables. We discussed batteries, the evolution of balancing markets, the explosive growth of datacenters, and the ever-growing grid connection queue — and, above all, how to keep the entire system stable and efficient through this transformation.
One of the most fascinating parts of the conversation focused on datacenters. NESO is currently facing more than 100GW of connection requests, while Fintan estimates that only 8–12GW are likely to materialise. He shared the three key criteria NESO uses to prioritise and filter applications — a crucial issue as electricity demand enters a new era.
Fintan is also a strong advocate for interconnectors. We discussed the strategic value of the current fleet and the long-term vision for expanding connections through the North Sea Islands and potentially even towards Canada.
Throughout the conversation, one message came across clearly: there is a highly competent team at the helm of the GB energy system, and the grid will continue to improve through investment, innovation, and digitisation.
Fintan embodies the calm confidence you want from the person helping run one of the most complex energy systems in the world. The ultimate “cool” operator.
