What were the striking figures on the electricity markets this month?
August put many market expectations to the test.
In the electricity market, there were sharp price spikes in the evening hours on several days, even though the summer months are typically characterized by calmer market dynamics. Even the much-discussed solar eclipse could not fully explain this behavior, as similar price movements were also observed the following day. The broader picture became clear: Europe still lacks the necessary flexibility when weather conditions and generation patterns change unexpectedly.
The gas market also delivered a surprise. TTF prices rose toward 70 €/MWh, reaching their highest level since early 2023. At the same time, European gas storage levels—at just 65 %—were significantly below both the previous year’s level and the five-year average.
During a period typically characterized by weaker demand and stable prices, August saw a remarkably strong summer rally.
What are the possible reasons for this market behavior?
In the electricity markets, a hot and exceptionally dry summer in Europe led to reduced availability of hydropower, increased strain on conventional power plants, and overall tight supply reserves. At the same time, demand proved to be more resilient than many had expected.
Several factors came together in the natural gas market:
- Restrictions in the Strait of Hormuz
- Unplanned Outages and Maintenance Work in Norway
- Ongoing Attacks on Ukraine's Energy Infrastructure
- Storage Filling in Europe Slower Than Expected
- More intense competition with Asia for LNG supplies due to a narrowing JKM-TTF spread
The result: The markets reacted sensitively to any potential disruption in supply. The „comfort zone“ of recent years seems to be gradually disappearing.
What do you expect for the next month?
For the electricity markets, the key factor will be whether weather conditions return to normal. Will rainfall replenish reservoirs and raise river levels, thereby easing the strain on generation and infrastructure? Or will increased volatility become the new normal?
In the natural gas market, geopolitical tensions between Iran and the U.S. remain the most significant influencing factor. With the upcoming heating season in mind, attention continues to focus on storage levels. However, an escalation in the Middle East, additional outages in Norway, or stronger LNG demand from Asia could further increase risk premiums.
One thing became clear in August: the electricity and natural gas markets remain extremely sensitive to uncertainty and Flexibility remains one of the most valuable commodities in European energy markets.
