German power prices jump as heatwave, lower wind lift supply needs

Impact of Weather and Renewable Output on German Power Prices

May 27 (Reuters) - German day-ahead power prices jumped 29% Wednesday as a heat wave across much of Europe raised cooling needs, while lower wind generation meant that more expensive electricity production sources, such as gas and coal-fired power plants, would be needed to cover demand.

Heatwave Drives Increased Electricity Demand

Much of Europe is experiencing higher-than-normal temperatures this week, raising demand for air conditioning and cooling systems and adding pressure on power grids.

Forecasts for Wind Power and Residual Load

  • German wind power output was forecast to fall by 9.7 gigawatts (GW) day on day to 4.4 GW for Thursday delivery, LSEG data showed.
  • Residual load, which covers non-renewable power generation sources, was seen rising by 8.2 GW to 23.5 GW, the data showed.
Temperature Projections Across Europe

Temperatures in Germany are expected to be as high as 30 degrees Celsius (86° Fahrenheit) in the south and west on Thursday, and above 30C during midday peaks in much of France, according to data from forecasters DWD and MeteoFrance.

Key Takeaways

  • Wind generation collapse: Forecast for May 28 delivery shows wind output dropping by 9.7 GW from the prior day to just 4.4 GW, pressuring prices.
  • Residual load surge: With renewables falling, non‑renewable (residual) load jumps by 8.2 GW to 23.5 GW, raising reliance on more expensive thermal sources.
  • Broader volatility backdrop: Earlier in May, Germany saw a 41 % week‑on‑week wind output decline and rising European power prices above €100/MWh amid tightening supply conditions (aleasoft.com)

Frequently Asked Questions

Why did German power prices surge on Wednesday?
German power prices surged due to forecasts for a steep decline in wind generation, increasing reliance on more expensive power sources.
How much is German wind power output expected to fall?
German wind power output is forecast to fall by 9.7 gigawatts (GW) day on day to 4.4 GW for Thursday delivery.
What does a drop in wind generation mean for residual load?
A drop in wind generation increases the residual load, reflecting greater reliance on non-renewable power sources.
