Latvenergo Expands Baltic Battery Storage and Solar Alongside Wind Deals

Latvenergo, Latvia’s state-owned utility, said on September 11, 2026, that it is evaluating the acquisition of up to 250 megawatts (MW) of wind or hybrid power projects across the Baltic region, adding to a portfolio that already includes a completed 265 MW solar park and a growing pipeline of battery storage projects. The search, advised by PricewaterhouseCoopers, is part of Latvenergo’s medium-term strategy to diversify its power mix and strengthen energy security in Latvia and neighbouring Baltic states.

Latvenergo said it will evaluate both ready-to-build projects and operational wind turbines no older than five years, then move to acquisition talks with developers of the most suitable sites. The company completed its 265 MW Aizpute solar park in Latvia in 2025, with generation starting in the first quarter of 2026.

Battery storage pipeline grows alongside the wind search

According to Latvenergo’s half-year results, seven battery storage projects totaling 233.4 MW and 551.2 megawatt-hours (MWh) of capacity were under development as of the end of June 2026, while two smaller battery energy storage systems (BESS) totaling 10.6 MW and 21.9 MWh had already been completed. A separate hybrid project at Priekule combines an 11.5 MW wind farm under construction, a 9 MW solar plant and a 2 MW battery storage system already in operation; Latvenergo has not disclosed the battery’s energy capacity or a commissioning date for the wind component.

Latvenergo’s current medium-term strategy targets 600 MW of new wind and solar capacity by 2026. Its approved Baltic renewable portfolio reached 1,144 MW by the first half of 2026, made up of 937 MW already built and 207 MW under construction. The company has said its long-term development potential runs as high as 2,300 MW, a ceiling it places beyond 2030 rather than as a near-term target.

Recent wind acquisitions and grid context

Latvenergo acquired the 124 MW Telšiai wind farm in Lithuania from developer Utilitas Wind in May 2024, a project using 20 Vestas turbines that cost roughly €200 million ($231.7 million) to build and is set to host a 28.51 MW/57.02 MWh battery storage system. It also acquired the 147 MW Pienava wind farm in Latvia from Swedish developer Eolus; as of the end of June 2026, all turbine foundations at the site had been completed, with substation and electrical infrastructure work under way. A separate 109 MW project, Laflora Energy, began generating electricity in the same period.

The acquisition push follows the Baltic states’ disconnection from the Russian-controlled electricity grid in February 2025 and their synchronisation with the Continental European grid, a shift that has raised the strategic value of domestic and regional generation capacity. Latvenergo has tied its expansion strategy directly to that energy-security context. On September 3, 2026, the company also joined 13 other energy companies and organisations from nine Baltic Sea countries, including Vestas, Siemens Energy and Eesti Energia’s Enefit, in forming the Baltic Energy Initiative, a cross-border platform for cooperation on offshore wind, hydrogen, carbon transport and storage, and energy infrastructure security.

Winss Solutions has previously explained the mechanics of this kind of buildout in its explainer on grid-scale battery storage, which covers how utilities like Latvenergo pair batteries with wind and solar to store surplus generation and release it during periods of peak demand.

About Latvenergo

Latvenergo is Latvia’s state-owned energy utility, generating and supplying electricity and heat domestically and expanding into wind, solar and battery storage across the Baltic region. In February 2025, the company first outlined plans to become the leading player in the Baltic battery storage market, targeting 250 MW/500 MWh of storage by 2030 across its existing hydro and combined-heat-and-power sites, starting with its CHPP-1 plant, Riga HPP and CHPP-2. The company has since extended that buildout into third-party wind and hybrid asset acquisitions, including its May 2024 purchase of the 124 MW Telšiai wind farm in Lithuania and its acquisition of the 147 MW Pienava wind farm in Latvia. The September 2026 search for up to 250 MW of additional wind or hybrid capacity, alongside its expanding battery storage pipeline, extends that strategy at a time when the Baltic states are prioritising energy security following their February 2025 disconnection from the Russian-controlled power grid.
