Snorkelling for Negative Prices
Why It Matters
Norway’s hydropower underpins much of Europe’s renewable electricity mix, so its reservoir shortfall could tighten supply and raise prices across the continent. Understanding the interplay of weather, snow storage, and market dynamics helps policymakers, utilities, and investors anticipate risks and plan for more resilient, flexible energy systems.
Key Takeaways
- •Norway's southern reservoirs at decade‑low levels after cold winter
- •Power flow flipped from export to import, first since 2019
- •Summer rainfall forecasts critical; wet summer could replenish reservoirs
- •Interconnectors let Norway import cheap solar, easing hydro deficit
- •Dry autumn could tighten supply before winter, experts warn
Pulse Analysis
Norway’s hydro‑dominated power system is under unprecedented stress after the coldest winter in 16 years and a 15 TWh precipitation deficit in the first quarter. Southern reservoirs sit at some of the lowest levels recorded in the past decade, forcing the country to shift from a net exporter of electricity to a net importer—a reversal not seen since 2019. This development matters for the broader European market because Norway’s interconnectors have long supplied cheap, renewable power to the continent, and any shortfall reverberates through neighboring grids.
Hydrological forecasts now hinge on summer weather. Analysts note a substantial snowpack deficit across the Nordic basin, meaning meltwater inflows will be below normal unless May‑June bring above‑average rain. Seasonal models suggest a wetter, windier Q3, which could refill reservoirs and curb negative prices, but a dry autumn would erode those gains and leave the system vulnerable before the winter heating season. While El Niño influences tropical climates, its direct impact on Scandinavian precipitation remains limited, leaving local rainfall patterns as the decisive factor for Norway’s 2024‑25 supply outlook.
Market participants are already adapting. The growing capacity of German solar and wind creates frequent negative‑price periods, prompting Norwegian hydro operators to curtail generation and store water for later months. Interconnectors now switch between imports and exports multiple times a day, reshaping the revenue curve and reducing the need for emergency spillage. Over the next decade, this flexibility will become essential as renewable penetration rises across Europe, but it also means tighter coordination is required to avoid seasonal deficits. For businesses, monitoring weather trends and interconnector flows will be key to managing electricity costs in the coming winter.
Episode Description
Norway - and the Nordic power system more generally - have seen fewer instances of negative prices than their continental counterparts in recent weeks. Why has the region been “snorkelling” while others have been plumbing the depths of negative prices.
Norway’s hydropower system is under pressure after one of the coldest winters in 16 years and a prolonged period of low precipitation. Reservoir levels in southern Norway remain well below normal, raising questions about energy security, winter preparedness and the growing role of Europe’s interconnected power markets.
But is the situation really as serious as headlines suggest?
Joined by some of the foremost experts on Norwegian hydropower and the market dynamics, together, they explore how low snowpack, dry weather patterns and shifting hydrological balances are affecting Norway’s power outlook — and why imported renewable energy from continental Europe may actually help save water in Nordic reservoirs ahead of winter.
The panel also dives into the explosion of negative power prices across Europe, the impact of Germany’s rapid solar buildout, whether batteries and grids can keep pace with renewables growth, and why some analysts believe Europe’s energy transition is entering a period of extreme volatility.
