Electricity Prices Surge to Nearly 6 Kronor per kWh in Southern Sweden Amid Power Supply Challenges

Electricity prices in southern Sweden have sharply risen, reaching up to 5.70 kronor per kilowatt-hour (kWh) on Tuesday evening, with the situation driven by multiple factors. Two and a half of the country's six nuclear reactors are offline for maintenance, including Ringhals 4, which is expected to restart but will take time to reach full capacity. Calm, windless weather across Sweden and neighboring Germany has also reduced wind power production, further limiting renewable energy supply. Additionally, high electricity prices in Germany are impacting southern Sweden's market.

Despite available gas and oil-fired power plants, these sources tend to incur higher costs due to fossil fuel price increases. In the electricity zones covering Svealand and Götaland (areas 3 and 4), the average price hovers around 1.90 kronor per kWh, spiking to 5.70 kronor during certain 15-minute intervals. Northern Sweden prices remain stable between 18 and 30 öre per kWh. A new price peak of approximately 3.50 kronor per kWh is expected Wednesday morning, though average daily prices should decline to 1.20-1.40 kronor per kWh as wind conditions improve and reactor operations normalize.

Consumers are also affected by taxes and network fees adding over one krona per kWh on top of base prices. Customers with quarterly or hourly pricing contracts face the brunt of the price surges, whereas those with variable monthly pricing experience less impact.

Johan Sigvardsson, analyst at electricity trading company Bixia, pointed to the windless weather and maintenance outages as central to the price jumps, noting the situation will ease as Ringhals 4 returns to full operation and wind power production picks up.
