Latvia generated 5,193 gigawatt-hours (GWh) of electricity in the first nine months of 2026, 17% more than in the same period of 2025, according to a market review by the transmission system operator AS Augstsprieguma tīkls (AST). TVNET and LETA published the figures on 19 October 2026.
Hydroelectric plants produced 1,956 GWh, 14.9% less than a year earlier. Solar plants produced 1,506 GWh, 2.5 times the previous year’s volume. Generation from natural gas reached 1,154 GWh, up 5.5%. Wind plants produced 264,599 megawatt-hours (MWh), up 83.7%. Biomass output was 189,342 MWh, down 6.4%, and biogas output was 70,666 MWh, down 22%.
Of the total, 4,156 GWh was produced in the transmission network, 17.4% more than in the first nine months of 2025, and 1,036 GWh in the distribution network, up 15.5%. National consumption over the nine months was 5,723 GWh, up 9.3%.
In September, output totalled 384,074 MWh, 16.3% more than in September 2025 and 4.3% more than in August 2026. The review said production rose sharply at several types of plant. With new wind parks connected to the transmission grid, wind output reached a historic high of 51 GWh, 49% above August and 3.5 times the level of September 2025.
Hydro output rose 85% to 149 GWh. Gas-fired plants posted the steepest percentage gain, with output up 2.7 times to 12 GWh. Biomass rose 21% to 16 GWh. Solar fell 37% to 140 GWh for seasonal reasons, yet was still 67% higher than a year earlier. Biogas was almost unchanged, down 1% to 7 GWh.
September consumption in Latvia rose 2% from August to 616 GWh and was 9.1% higher than a year earlier. Domestic generation covered 62.39% of national consumption, 1.4 percentage points more than in August.
Across the Baltic states, September consumption rose 3% to 2,187 GWh. The fastest increase was in Estonia, at 4%, while consumption in Lithuania and Latvia each rose 2%. Combined Baltic generation rose 6% to 1,710 GWh. Lithuania led with an 8% increase; Latvia’s generation rose 4% and Estonia’s by about 1%.
European electricity prices set a new high for the year for a second consecutive month. Compared with August they rose 11–21%, to 140–156 euros per MWh. The review attributed the rise mainly to high natural-gas prices and weaker solar and wind output. Autumn reduced solar production, and prolonged calm periods reduced wind output in Europe. Renewable generation in the Baltics limited a sharper price rise. The average Baltic price was 97.41 euros per MWh, well below prices elsewhere in Europe, though 33.7% above August.
Slightly higher Baltic demand, linked to cooler weather, pushed prices up. Wind and hydro output increased, but not enough to offset the seasonal shortfall in solar power from shorter days. In Latvia’s bidding zone the price rose 36.2% to 108.68 euros per MWh. In Lithuania it rose 36% to 108.59 euros, and in Estonia 27.3% to 74.97 euros. In connected Nordic zones the rise was steeper: Finland’s average climbed 38.2% to 57 euros per MWh, and Sweden’s fourth bidding zone rose 47.1% to 106.98 euros per MWh.
Electricity imports into the Baltic states fell 5.9% from August to 753 GWh, ending the upward trend of previous months. Imports from Sweden dropped 21.8% to 180 GWh, imports from Finland slipped 0.4% to 548 GWh, and imports from Poland rose 23.7% to 25 GWh.
