Ignitis Launches Commercial Operations at 173.6 MW Tume Solar Farm in Latvia

Lithuanian energy group Ignitis has announced the start of commercial operations at its 173.6 MW Tume solar farm in Latvia’s Tukums municipality, marking the completion of a major stage in one of the Baltic region’s largest solar projects.

The project, developed by Ignitis Renewables, represents an investment of up to €106 million. Covering approximately 302 hectares, the solar farm contains more than 282,000 panels and is expected to generate enough electricity annually to meet the demand of around 85,000 households, according to the company.

Ignitis is also developing a 107.2 MW / 214.5 MWh battery energy storage system at Tume. The facility remains under construction and will be integrated with the solar farm to improve operational flexibility and electricity management.

The commissioning increases Latvia’s domestic renewable generation capacity, while the planned storage system will add flexibility to the project once operational.
