Jan 15, 2025
Catherine Porter, an independent energy consultant, delves into the UK's precarious energy situation. The discussion reveals how recent near-blackout incidents expose vulnerabilities in the national grid. Porter highlights the critical balance between renewable energy reliance and gas imports, stressing the need for greater transparency. As Britain approaches its 2030 Net Zero goal, the potential for blackouts looms large, urging public preparedness. The conversation also considers the role of nuclear energy and the complexities of transitioning to reliable energy sources.

Episode notes
Grid Balancing and Complexity
- National Grid ESO (NISO) balances electricity supply and demand, using price signals to incentivize power stations.
- The grid's complexity arises from constraints and uneven distribution of demand.
Renewables and Grid Instability
- Renewables introduce grid instability because they generate direct current, unlike conventional generators that create a stable alternating current wave.
- This lack of inertia from renewables can lead to blackouts.
January 8th Near-Blackout
- On January 8th, high demand, low wind, and limited import capacity led to a capacity market notice and an electricity market notice.
- A Loss of Load Probability (LULP) reached 29%, suggesting a significant risk of blackouts.
