This episode of Switched On discusses the declaration of a Super El Niño, its global weather impacts, and the implications for power and commodity markets. Analysts Jess Hicks and Ryan Ward explain how this strong climate event, developing against a warmer backdrop, increases the risk of compound events like heat waves coinciding with low wind generation, leading to market volatility, while also creating unique tensions for hurricane and wildfire outlooks.
Summarized by Podsumo
A Super El Niño, defined as ocean temperatures more than 2°C above normal in the equatorial Pacific, has been declared and is expected to amplify global weather risks for power markets.
El Niño can paradoxically both reduce certain risks (like hurricane formation in the Atlantic) and increase others (like wind droughts and heat waves in Europe, and precipitation shifts in the US).
In Europe, the main concerns are compound events—such as simultaneous high temperatures, low wind speeds, and dry conditions—that strain renewable generation and raise price spikes.
The US faces a dual risk: a milder winter backdrop (which can lower gas demand) but a higher chance of volatility from surprise cold outbreaks, hurricanes threatening LNG infrastructure, and wildfires in the West.
The hurricane season forecast is unusually uncertain because warm Atlantic waters are competing with El Niño’s wind shear, meaning even a below-average season can still deliver one very damaging storm.
"For power markets, the biggest threat is often compound risk, where multiple weather events happen at once, like extreme heat coinciding with low wind generation, for example. These compound events are where most volatility can really emerge. — Jess Hicks"
"I almost think it's the opposite. The volatility can be really high during these ENSO events. — Ryan Ward (on whether a strong El Niño reduces volatility)"
"When you have a wind drought, it's essentially an extended period of unusually weak wind speeds... so that matters much more today than it would have a year ago, or a decade ago, or 20 years ago, because wind has become so important in the European power system. — Jess Hicks"
