Latvia generated 5,193 gigawatt-hours (GWh) of electricity in the first nine months of this year, 17% more than in the same period of 2025, according to a market review by the transmission system operator AS Augstsprieguma tīkls (AST).
Hydropower plants produced 1,956 GWh, 14.9% less than a year earlier. Solar plants produced 1,506 GWh, 2.5 times more than in the same period last year. Natural-gas plants produced 1,154 GWh, up 5.5%. Wind plants produced 264,599 megawatt-hours (MWh), up 83.7%. Biomass plants produced 189,342 MWh, down 6.4%, and biogas plants produced 70,666 MWh, down 22%.
Of the total, 4,156 GWh was generated in the transmission network, 17.4% more than in the first nine months of last year, and 1,036 GWh in the distribution network, up 15.5%. Electricity consumption over the nine months was 5,723 GWh, 9.3% higher than a year earlier.
In September, Latvia generated 384,074 MWh, 16.3% more than in September last year and 4.3% more than in August. With new wind parks connected to the transmission grid, wind output reached a record 51 GWh. That was 49% more than in August and 3.5 times the level of September last year.
Hydropower output rose 85% to 149 GWh. Natural-gas plants recorded the sharpest percentage increase, with output 2.7 times higher at 12 GWh. Biomass plants produced 16 GWh, up 21%. Solar output fell 37% to 140 GWh because of the season, yet it was still 67% higher than a year earlier. Biogas output 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 Lithuania and Latvia each rose 2%. Baltic generation rose 6% to 1,710 GWh. Lithuania’s output increased 8%, Latvia’s 4% and Estonia’s 1%.
European electricity prices reached a new high for the year for a second month in a row. Compared with August they rose 11–21% to 140–156 euros per MWh. AST said the rise was driven mainly by high natural-gas prices and weaker solar and wind output. Autumn cut solar production, and long calm spells reduced wind output in Europe. Renewable generation in the Baltics limited a steeper price rise. The average Baltic price was 97.41 euros per MWh, well below prices elsewhere in Europe, though it was 33.7% higher than in August.
Slightly higher consumption in cooler weather added to the Baltic price increase. Wind and hydropower output rose, but not enough to offset the seasonal drop in solar power as days shortened. In the Latvian bidding zone the price rose 36.2% to 108.68 euros per MWh. In Lithuania it rose 36% to 108.59 euros per MWh, and in Estonia 27.3% to 74.97 euros per MWh. 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 ended the upward trend of previous months and fell 5.9% from August to 753 GWh. Imports from Sweden dropped 21.8% to 180 GWh, while imports from Finland slipped 0.4% to 548 GWh. Imports from Poland rose 23.7% to 25 GWh.
