Power Market Disruption: Epex Spot IT Glitch Caused Record Price Spread
An IT glitch on Europe's largest power exchange, Epex Spot, caused the German power price to surge to its highest level since August 2022. The malfunction led to several countries, including France, Germany, Austria, Belgium, the Netherlands, and Poland, being decoupled from the power grid. This resulted in a record-wide price spread between Germany and France, with German day-ahead power clearing at €492.04 per megawatt-hour, while French prices dropped to €2.96. The disruption affected the market coupling mechanism, which typically optimizes electricity flow across borders based on supply and demand, ensuring efficient use of renewable energy sources like wind and solar. The incident highlights the vulnerability of interconnected power systems to technical issues.
Key Takeaways
