Electricity prices hit unusual June highs

Denmark’s average electricity price has reached its highest level for June since 2022, according to energy company Norlys.

The surge is driven by a combination of high temperatures and rising fossil fuel prices, the company stated in a press release. On Tuesday evening, the spot price peaked at 4.80 DKK per kilowatt-hour for customers in Jutland and Funen, while Zealand saw 4.70 DKK.

Mads Brøgger, director of Norlys’ energy division, noted that while Danish households have grown accustomed to paying over 2 DKK per kilowatt-hour after taxes and fees, such high averages have not been seen since the 2022 energy crisis. “That’s what makes this remarkable,” he said.

Energy provider OK reported similar trends, with prices not only elevated but also more volatile. Daily swings of up to 5 DKK per kilowatt-hour have been recorded—an anomaly that occurred only once in all of 2025.

Solar power is currently the only significant factor keeping prices in check, OK added. Meanwhile, heatwaves across Europe have spiked demand for air conditioning, particularly in southern regions. French nuclear plants, usually cooled by rivers, are struggling as water temperatures rise and levels drop, reducing output. Additionally, low wind speeds in several countries have limited wind power generation.
