Wholesale electricity prices in Nord Pool's Lithuanian, Latvian and Estonian bidding areas averaged 28.5% on May 4-10. The average price across the power exchange went up by 9% to 8.15 euros, the independent electricity supplier said.
"Prices in the Nordic countries were mainly affected by the continuing dry and cold weather, which further reduced the hydrological balance," said Karolis Bagdonas, corporate client manager at Elektrum Lietuva.
The three Baltic countries' total power consumption declined by 2% to 458 gigawatt-hours (GWh).
Their overall electricity production edged down by 1% to 198 GWh, covering 43% of the region's needs.
