Lithuanian Grid Operator Reports Price Swings Amid Renewable Energy Fluctuations
Lithuania’s power grid operator, Litgrid, has reported significant volatility in electricity prices in recent days, driven largely by changes in wind energy production. The fluctuations highlight the increasing reliance on renewable sources and the challenges of maintaining grid stability as traditional energy sources are phased out.
On March 29, 2025, Litgrid announced that the country experienced a 69% increase in electricity prices due to reduced output from wind farms, as reported by LRT. Conversely, electricity prices returned to normal levels on Sunday, with the first negative prices of the year recorded, according to reports.
The price swings come as Lithuania continues to integrate more renewable energy into its grid. Litgrid also reported a record-breaking export volume to Sweden during the week, with prices falling 60% as noted by vz.lt.
In May 2024, the “NordBalt” electricity connection between Lithuania and Sweden was successfully reconnected after repairs following a fault on the Swedish side, as reported by Ūkininko patarėjas. The 700 MW connection has been operational since 2016.
Litgrid also reported that in early May 2024, the “NordBalt” connection had a market availability of over 99% throughout the year and in 2023, 4.967 TWh of electricity was imported from Sweden through this connection, according to Delfi. The company noted that increased wind power generation also contributed to changes in electricity prices, as Litgrid stated.
In March 2025, Litgrid also disconnected the “NordBalt” electricity connection with Sweden due to a fault in the converter station on the Swedish side, as reported by 15min.lt. Reserves were activated, and electricity supply to consumers in Lithuania was not disrupted.
