AB Ignitis grupė has confirmed that the Tume solar farm in Tukums municipality, Latvia, has reached its commercial operations date (COD), marking a significant milestone for the Lithuanian energy group's renewables expansion. The 173.6 MW project, developed by subsidiary UAB Ignitis Renewables, is described as one of the largest solar energy projects in the Baltics. With total investments of up to EUR 106 million, the announcement signals continued execution of Ignitis Group's green capacity growth strategy, though the company confirmed the development does not affect its 2026 financial guidance.

Key Points

  • AB Ignitis grupė (IGN) is a Lithuanian-headquartered energy group operating across the Baltic region
  • The 173.6 MW Tume solar farm in Latvia has achieved its commercial operations date (COD)
  • Total investment in the project amounts to up to EUR 106 million; Group installed Green Capacities now stand at 2.3 GW
  • Investors should watch progress on the 107.2 MW / 214.5 MWh Tume battery energy storage system, currently under construction

Tume Solar Farm Reaches COD as One of the Baltics' Largest Solar Projects

The Tume solar farm, situated across 302 hectares in Tukums municipality, Latvia, comprises more than 282,000 solar panels and carries a generation capacity of 173.6 MW. The announcement states the facility is expected to meet the electricity demand of approximately 85,000 households. Developed through Ignitis Group's subsidiary UAB Ignitis Renewables, the project represents a material addition to the Group's operational renewable portfolio and reinforces the company's strategic focus on scaling green energy assets across the Baltic states.

Group's Installed Green Capacities Rise to 2.3 GW Following Tume COD

Since the Tume solar farm reached its commercial operations date, Ignitis Group's total installed Green Capacities have increased to 2.3 GW, up from 2.1 GW previously. This incremental growth reflects the Group's active pipeline execution and aligns with the strategic priorities outlined in its Strategic Plan 2026–2029. The company confirmed that this development does not affect its Adjusted EBITDA or Investments guidance for 2026, providing investors with clarity on near-term financial expectations following the milestone.

107.2 MW Tume Battery Energy Storage System Remains Under Construction

Alongside the now-operational solar farm, Ignitis Renewables is developing the Tume battery energy storage system (BESS), rated at 107.2 MW with a storage capacity of 214.5 MWh. The BESS is currently under construction and is intended to be integrated directly with the Tume solar farm. The company states the system is designed to enhance the efficiency and flexibility of the broader project. Investors may be watching the BESS completion timeline closely, given that paired storage assets are increasingly valued for their contribution to grid stability and renewable energy dispatchability.

EUR 106 Million Investment Supports Latvia's Renewable Energy Security Goals

Total investments in the Tume solar farm will amount to up to EUR 106 million, according to the announcement. The company states that the project will contribute to increasing local renewable electricity generation in Latvia and strengthening regional energy security — a particularly pertinent objective given ongoing discussions around Baltic energy independence. The Tume development forms part of Ignitis Group's broader ambition to grow its green capacity base, with further details available through the Group's publicly disclosed Strategic Plan covering the period 2026 to 2029.
