European winter energy risks are intensifying once again. Slow inventory replenishment, Middle East supply disruptions, and lower winter renewable energy output are jointly pushing prices higher. The European power market is issuing its strongest price alarm since the energy crisis as it enters the winter season. Data from the European Energy Exchange shows that Germany's benchmark power price for January next year has climbed above 180 euros per megawatt-hour, up more than 60% from a year ago. As one of Europe's largest power markets, Germany's price has clearly broken away from the relatively stable range seen over the past year.

Natural gas is the primary driver behind this surge in power prices. Europe's gas storage replenishment has been slow in recent weeks, global competition for liquefied natural gas cargoes has reignited, and after Middle East conflict led to the closure of the Strait of Hormuz, Qatari supplies have been disrupted, pushing European gas prices higher. Gas-fired plants still play a critical role in balancing Europe's power system, so fuel price changes quickly transmit through to electricity costs. Rising power prices are now bringing energy pressure back into the inflation discussion. As Bloomberg notes, higher wholesale electricity prices will increase household bills and corporate costs, at a time when markets are already betting on further rate hikes in Europe. Europe showed greater resilience to this year's energy shock than in 2022, but the renewed spike in winter power prices demonstrates that energy costs can still rapidly penetrate the real economy.

Gas reserves push risks toward winter

French nuclear power supply has been affected this year by high temperatures and strikes, while hydropower inventories also remain at low levels, stripping Europe's power system of some low-cost supply buffers. Winter solar generation is naturally far lower than in summer, and short daylight hours and cloudy conditions in Nordic regions further limit output. Whether wind power can maintain high generation levels will directly influence demand for gas and coal-fired power. Europe's gas storage is currently only at 69%, significantly below the roughly 85% average for the same period over the past five years. Germany and the Netherlands together hold about 35% of EU storage capacity, yet they are the main markets where replenishment is lagging. High energy prices are causing companies to delay procurement and reducing governments' willingness to push through with mandatory storage targets. Europe's benchmark gas price has risen to 81 euros per megawatt-hour, up 150% year-on-year and above the "adverse scenario" level previously set by the European Central Bank. Morgan Stanley projects that if winter weather turns colder, gas prices could climb further to 100 euros per megawatt-hour. The longer replenishment is postponed, the closer procurement moves to peak winter demand, concentrating price pressure.

Monetary policy is already feeling the impact of energy prices. The European Central Bank raised interest rates last week, with policymakers indicating that further action may still be needed if energy price pressures fail to ease. Research published by the Bank of Italy in June this year found that compared with oil price shocks, gas price shocks have a stronger and longer-lasting effect on inflation and are more likely to enter the core inflation metrics closely watched by central banks. ECB Governing Council member Peter Kazimir has explicitly stated that his focus is now shifting from oil and fuel prices toward gas and electricity prices. Financial markets are beginning to reassess policy rate trajectories accordingly, with some investors expecting the ECB may need to deliver multiple additional rate hikes.

Price shock far smaller than 2022, but transmission is more direct

Current supply risks remain far smaller than in 2022. When Russian pipeline gas collapsed that year, European power prices briefly exceeded 1,000 euros per megawatt-hour - more than five times the current level of Germany's January futures contract. Over the past four years, Europe has added LNG import infrastructure, reduced fuel consumption, and diversified supply sources, lowering the probability of physical shortages. But the new cost is Europe's greater dependence on the global LNG market. Europe now competes with buyers in Asia and other regions for spot cargoes, meaning supply disruptions thousands of kilometres away can quickly show up in gas and power prices. Storage facilities can cushion short-term shocks but cannot fully isolate Europe from global price movements. Ulf Ek, Chief Investment Officer at Northlander Commodity Advisors, expects that if winter turns colder while Middle East supply remains constrained, European wholesale power prices could rise by up to 50% from current levels. Household bill increases will be smaller than wholesale market movements because power suppliers typically purchase in advance, but UK household energy bills are already projected to rise 25% in January, while Norwegian consumers receive greater protection through government subsidies.

Higher power prices are also reshaping earnings expectations for electricity producers. Jefferies analyst Ahmed Farman estimates that generators including Germany's RWE, France's Engie, and EDP Renewables could see next year's profits come in around 10% higher than current market consensus. More expensive gas and coal-fired generation often sets the marginal power price, so low-cost producers benefit from rising wholesale prices. Renewables are still easing some of the price pressure. Analysis provided by Baringa to Bloomberg shows that without the solar capacity added since 2021, Europe's average summer wholesale power prices would have been 30% higher this year. Winter solar output declines sharply, leaving the power system more reliant on wind performance and gas-fired units for balancing capability. Baringa economist Caspian Conran expects Europe to experience a "painful, difficult" winter with a clear impact on household energy bills, though nothing on the scale of prices seen during the 2022 Ukraine crisis phase. If winter weather turns out mild, wind and precipitation are favourable, and Middle East tensions ease, gas and power prices could still retreat relatively quickly.
