The Baltic prices were below the Nord Pool power exchange's average price, which went down by 1% w-o-w to 42.09 euros per MWh, the independent electricity supplier said.
"The price changes were due to increased precipitation, slightly warmer temperatures and a decline in prices for fuel for electricity generation," Karolis Bagdonas, head of the important client segment at Elektrum Lietuva, said.
"Admittedly, a slight decrease in wind power generation kept the prices from falling even faster," he added.
The Baltic countries' total power consumption last week dropped by 1% on average to 563 gigawatt-hours (GWh), while their overall electricity production increased by 5 % to 395 GWh.
Locally-generated electricity covered 70% of the region's needs.
