Jul 7, 2025 Steve Berberich, a global energy expert and former CEO of CAISO, joins the discussion to unpack the Iberian blackout. Unlike previous failures, this incident didn't arise from extreme weather, but rather structural flaws within Spain's grid. The conversation reveals regulatory gaps, design issues, and operational errors that contributed to the blackout. Steve compares this event with other significant blackouts, shedding light on common patterns and necessary reforms. The insights underscore the urgent need for accountability and better energy management to prevent future crises.

Episode notes
California 2020 Blackout Experience
- The 2020 California blackout was caused by insufficient power supply during a hot period and lack of adequate planning.
- Despite load shedding, there were no system stability issues like frequency deviation or voltage collapse.
Understanding the Duck Curve
- The duck curve illustrates the high ramping needs due to solar power's daily output fluctuations.
- Batteries can soak up excess daytime solar power and discharge it during peak ramp down periods, enabling grid stability.
Batteries as Key Grid Solution
- Deploy large-scale batteries to manage solar power variability and reduce curtailment.
- Use battery storage to absorb low-cost renewable energy midday and discharge during evening ramps.
