European Power Prices Rise as Wind Forecast Is Revised Down
Germany, UK Power Prices Surge Amid Weather Shifts and Wind Generation Forecasts
European power markets are bracing for a challenging winter as historical lows in wind generation forecasts and increased heating demand push prices upward. This shift is most evident in Germany and the United Kingdom, where week-ahead power prices have witnessed significant hikes last week.
In Germany, power prices shot up by 12% to €122 per megawatt-hour, with the UK experiencing similar spikes, nearing 14% to £109.4 per megawatt-hour, according to broker data compiled by Bloomberg. The key driver behind this surge is the revised wind generation forecast, which has been downscaled from predictions of 25 to 30 gigawatt-hours daily to below 20 gigawatt-hours for most days, as analyzed by Oslo-based firm Veyt.
Europe’s growing reliance on intermittent renewable energy sources has created a precarious balance. When wind doesn’t blow or the sun doesn’t shine, the gap is filled by pricier gas-fired plants. The colder-than-usual January temperatures have exacerbated this issue, with many regions expecting below-average temperatures throughout the month. This scenario is particularly concerning given that wind and solar output are integral to the continent’s power grid.
On Monday, Veyt noted that lower wind generation during this period could be a “bullish signal for European carbon.” The note added that the limited renewable power would lead to more fossil-based generation, increasing demand for European Union carbon allowances.
This trend is reflected in the dramatic dip in wind generation forecasts. In Germany, wind energy output is expected to drop from 24,000 megawatts on Tuesday to as low as 2,200 megawatts on Wednesday. Similarly, in the United Kingdom, wind power is predicted to decline from about 15,000 megawatts on Monday to as low as 3,600 megawatts on Thursday. German solar power generation is also expected to decrease from around 13,000 megawatts on Tuesday to 4,500 megawatts on Wednesday, further destabilizing the energy landscape.
The phenomenon known as the “Dunkelflaute” or periods of low solar and wind energy production, has been observed this winter, leading to unprecedented spikes in power prices. In the UK, some hours saw prices break past £1,000 per megawatt-hour, while in Germany, prices exceeded €1,000 a megawatt-hour for several hours in December due to similar weather conditions.
In other markets, French day-ahead power prices rose to €189.5 per megawatt-hour for the hour starting at 7 p.m., marking the highest level in a month. Demand forecasts for the following days indicate peak levels, with Tuesday’s demand projected at 82.8 gigawatts—the highest in more than a year—according to French grid operator RTE.
As the continent grapples with these challenges, the scenario sets the stage for a complex winter of energy management, where balancing supply and demand will be crucial. The variability in renewable energy sources continues to reshape the European power landscape, necessitating flexible and adaptive strategies to meet the evolving needs of the grid.

Conclusion:
The latest surge in power prices across Germany and the United kingdom is a stark reminder of the complexities and challenges associated wiht relying heavily on intermittent renewable energy sources. The sharp 12% increase in German week-ahead power prices to €122 per megawatt-hour, coupled with the UK’s 14% hike to £109.4 per megawatt-hour, underscores the vulnerability of these markets to weather-driven fluctuations and inaccuracies in renewable energy forecasts. The revised wind generation forecast from Oslo-based firm Veyt, downscaling predictions from 25 to 30 gigawatt-hours daily to below 20 gigawatt-hours, has exacerbated the situation, highlighting the need for enhanced predictive models and grid resilience.
As Europe continues to transition towards a renewable energy-dominated system, it is critical to address the inherent instability introduced by intermittent sources. The current setup can lead to price volatility and increased reliance on fossil fuels during periods of low renewable generation, hindering economic competitiveness and driving deindustrialization, as seen in countries like Germany and the UK.Therefore, policymakers must prioritize stabilizing the electricity market by investing in advanced forecasting technologies, enhancing grid flexibility, and implementing strategies to integrate renewable energy more seamlessly into the system. This multifaceted approach will help mitigate the adverse impacts of weather-driven price surges, ensuring a more lasting and economically robust energy future for Europe.
Ultimately, the challenge posed by integrating intermittent renewables into European power grids demands a holistic and proactive approach, combining cutting-edge technology with strategic policy decisions. By fostering a more resilient and adaptable energy system, Europe can navigate the complexities of climate change while maintaining economic competitiveness and ensuring stable, affordable electricity for both households and industries.
Conclusion
As europe’s power markets face a challenging winter, underscored by ancient lows in wind generation forecasts and increased heating demand, the pressure on power prices has never been more pronounced.In Germany and the United kingdom, week-ahead power prices have witnessed significant hikes, with Germany’s power price surging by 12% to €122 per megawatt-hour and the UK reaching a 14% increase to £109.4 per megawatt-hour,according to broker data compiled by Bloomberg.
The key driver behind this surge is the revised wind generation forecast, which has been downscaled from predictions of 25 to 30 gigawatt-hours daily to below 20 gigawatt-hours for most days. This precarious balance between intermittent renewable energy sources and costly fossil-fired plants is exacerbated by colder-than-usual temperatures in January, with many regions expecting below-average temperatures throughout the month.
The dramatic dip in wind and solar generation forecasts highlights a critical issue: the reliance on renewable sources is not translating into stable and affordable power. For instance,in Germany,wind energy output is expected to drop from 24,000 megawatts on Tuesday to as low as 2,200 megawatts on Wednesday,while in the UK,wind power is predicted to decline from about 15,000 megawatts on Monday to as low as 3,600 megawatts on Thursday.
These conditions have led to unprecedented spikes in power prices, with some hours in the UK seeing prices break past £1,000 per megawatt-hour and similar situations in Germany, where prices exceeded €1,000 a megawatt-hour for several hours in December. The phenomenon known as the “Dunkelflaute” or periods of low solar and wind energy production, witnessed this winter, underscores the need for robust energy management strategies.
As the continent grapples with these challenges,it is evident that balancing supply and demand will be crucial during this complex winter of energy management. european policymakers and energy regulators must navigate these fluctuations strategically to ensure stable power supplies, leveraging technological advancements and innovative solutions to integrate renewable sources more effectively into the grid. The variability in renewable energy sources continues to reshape the European power landscape, demanding proactive measures to mitigate price volatility and ensure energy security for the future. Ultimately, this scenario sets a critical stage for fostering a resilient and adaptable energy system capable of meeting Europe’s diverse needs in an increasingly dynamic environment.
