Decembers of 2024 and 2025 were similar. Electricity consumption was roughly the same in both years. In December 2025, the average consumption was 1038 megawatts, compared to 1045 megawatts in December 2024.
The price of electricity in December 2025 was lower than the previous year. The average price was 73.67 euros per megawatt-hour. This is more than 10 euros cheaper than in December 2024.
The lower price was due to limited connection capacity with Latvia, favorable wind conditions, and warmer weather. Warmer weather also reduced electricity consumption.
Heat consumption in Tallinn decreased by five percent. The outside air temperature was one degree higher, but heat consumption decreased less. This is also due to new buildings that joined Tallinn's district heating network.
December was warmer than average. Estonia's average air temperature was +2.4 degrees, which is 3.4 degrees higher than usual. The warmest day was December 10 in Heltermaa, where the temperature was 9.3 degrees. The coldest day was the last day of the year in Kuusiku, where the temperature was -15.8 degrees.
Estonia's average precipitation in December was 49 mm, which is 93 percent of the norm. The most precipitation fell on December 9 in Lääne-Nigula, with 12 mm. There were an average of 18 hours of sunshine in December, which is 83 percent of the norm.
