Estonia recorded the steepest week-on-week increase in the average price of electricity, by 4.5 % to 54.79 euros per MWh. The average price in Latvia rose by 2 % to 59 euros and that in Lithuania was up by 1.7% to 58.93 euros.
According to Elektrum Lietuva, electricity prices rose across the Nord Pool region.
"The price changes are due to a long term shortage of rainfall and low wind power generation," the independent power supplier said in a press release.
"In Lithuania and Latvia, the price growth is also due to NordBalt repairs," it added.
The Baltic countries' total power consumption edged down by 0.1% on August 20 through 26 from a week earlier to 479.5 gigawatt-hours (GWh).
Lithuania was the only of the three countries to register an increase in consumption, up by 3.4% to 218.8 GWh. Consumption declined by 0.7% to 129.5 GWh in Latvia and by 4.9% to 131.2 GWh in Estonia.
