Ignitis brings Latvia’s 174 MW Tume solar farm into commercial operation

Ignitis Renewables’ approximately 174 MW Tume solar farm in Latvia has reached commercial operation, the company announced on 6 November.

The development in Tukums municipality covers 302 hectares and contains more than 282,000 panels. It is the company’s first project to use tracking equipment that follows the sun during the day.

Tume also marks a change in maintenance arrangements: Ignitis says its own specialists will provide most of the project’s operations and maintenance, expanding its internal capability as its regional portfolio grows.

A co-located battery with approximately 107 MW of power capacity and 215 MWh of storage is still under construction. Commercial operation of the solar farm therefore does not mean the battery is already delivering services.

The distinction matters for grid operations: solar generation has reached its operating milestone, while the flexibility expected from storage depends on completion and commissioning of the separate battery project.
