As Europe prepares for the upcoming winter, a complex interplay of factors is shaping the power landscape. With energy prices fluctuating, demand patterns evolving and geopolitical tensions lingering, understanding these dynamics is critical for stakeholders across the energy sector.
- European power markets face heightened uncertainty because of fluctuating prices, diverging demand recovery and geopolitical risks.
- Renewable energy variability continues to present challenges in forecasting.
- Strategic planning and advanced forecasting models will be crucial for navigating the coming winter’s market volatility.
Trends shaping Europe’s power market
The European power market has witnessed significant volatility, particularly with rising gas prices over the summer. Our predictions for Germany and the UK aligned closely with actual outcomes; in contrast, France's bearish price forecast stemmed from underestimated exchange restrictions.
Demand recovery also reflects a mixed narrative across Europe. In Germany, demand increased by approximately 1.7%, aligning with expectations as the country continues to recover from pandemic-induced fluctuations. In France, a weaker-than-anticipated summer demand recovery resulted in slight year-on-year growth of around 1%. This underperformance has tempered winter expectations. In contrast, the Nordics have fully rebounded from the energy crisis, with demand returning to historical averages, setting a positive tone for the winter season.
Renewable energy generation remains a cornerstone of Europe's energy transition. Solar generation across the continent, particularly in Germany, matched forecasts, benefiting from lower variability compared to wind energy. Wind forecasting remains a challenge due to unpredictable weather patterns, with generation falling within predicted ranges but still presenting a risk factor.
Hydro conditions have significantly improved in the Nordics, aiding in price suppression across the region. France's robust hydro generation has similarly contributed to bearish price fundamentals. Conversely, France's nuclear production remains weak, compounding its bearish outlook and influencing regional pricing dynamics.
The geopolitical landscape adds another layer of complexity. Anticipated price spreads between Germany and France in the first quarter could lead to negative spark and dark spreads—an unusual occurrence for this time of year. The increase in negative price hours, particularly due to solar overproduction, highlights the widening gap between peak and off-peak power in countries like Germany and Spain.
Upcoming winter weather outlook
Our summer forecast correctly anticipated warmer conditions across central and eastern Europe, with above-average rainfall leading to flooding in many areas. The early winter months saw accurate predictions of colder conditions in the Nordics and expected precipitation patterns.
Climatic drivers, including the North Atlantic Oscillation (NAO) and Arctic Oscillation (AO), play a crucial role in shaping weather patterns. For the forthcoming winter, these drivers exhibit quieter behaviour, leading to reduced confidence in forecasts. With a positive NAO expected to support warmth in northern Europe, the likelihood of severe cold spells appears diminished.
Forecasts indicate near-normal winter temperatures across Europe, with slightly warmer conditions anticipated in the UK, France and Scandinavia. However, Eastern Europe faces a higher probability of colder weather. Precipitation patterns suggest drier conditions for most of continental Europe, particularly in Germany and Poland, while parts of Scandinavia may experience slightly wetter weather.
Winter power outlook
Continental Europe is poised to experience a 4% increase in demand from October to March, driven by a return to average weather conditions and ongoing electrification trends. Notably, the anticipated growth in solar capacity is expected to yield an additional 5 terawatt-hours (TWh) of generation compared to last year.
The bullish forecast for Germany and France suggests power prices will rise by €3-19 per megawatt-hour (MWh) compared to current market expectations. Notably, a negative price spread between France and Germany is emerging, reflecting shifting market dynamics.
Two scenarios highlight the potential volatility ahead:
- Increased lignite and coal capacity: The return of decommissioned lignite and coal plants could yield price reductions during peak months, aligning net exports with fuel prices.
- Fuel price fluctuations: A 20% decrease in gas prices could reduce power prices by 16-17%, while a 20% increase may lead to significant price hikes, particularly in peak periods.
The Nordic region enters winter with an improved hydro balance, a positive shift from last year. Spot prices are anticipated to decline following strong hydro production, in contrast to the price spikes experienced in late 2022. With wind capacity in the Nordics nearing 40GW, a 10% increase in power output is expected. Consumption is recovering from 2022 declines and is projected to reach levels like 2021. The implementation of a new northern flow-based market coupling system is expected to facilitate increased cross-border power flows, potentially altering pricing dynamics within the region.
The winter ahead carries both challenges and opportunities, making strategic planning and proactive measures essential for resilience and sustainability.
