The transmission system operator attributed the growth in domestic production to a four-fold year-on-year increase in generation at combined heat and power plants.
Giedrius Radvila, the director of the Power System Operations Department at Litgrid, said CHP plans, especially the Elektrenai facility, boosted production because of low natural gas prices.
"This increased the overall amount of energy produced in Lithuania and reduced imports from third countries," he said in a press release, adding that "trade flows from Scandinavia remained unchanged".
Lithuania imported a total of 2,705 GWh of electricity and exported 981.5 GWh during the quarter.
Y-o-y, imports from Russia dropped by 27% to 1,020 GWh, imports from Sweden declined by 14% to 997 GWh, and imports from Belarus slumped down by 32% to 156 GWh. Imports from Latvia surged by 42% to 444 GWh.
Lithuania's total electricity needs decreased by 4% in the third quarter from a year ago to 3,096 GWh and its overall consumption edged down by 1.1% to 2,606 GWh.
