The BESS will provide balancing services to the grid, primarily FCR, aFRR, and mFRR, as well as balance supply and demand on the grid.

“Although the average electricity consumption in Lithuania is around 1,500 megawatts, the installed capacity of both solar and wind power plants is expected to exceed 2,000 megawatts in 2025, enabling surplus electricity to be stored and supplied to consumers during peak hours”, said Gediminas Uloza, CEO of E energija Group.

Local system integrator will supply the energy storage solution, using battery units from CATL, power conversion systems (PCS) from Power Electronics, and its own proprietary energy management system (EMS), NordNest.

E energija Group claimed the solution meets the strictest requirements of the country’s transmission system operator (TSO), enabling it to provide services across the Baltics and facilitate the integration of interconnections.

The Baltic region only a few weeks ago disconnected from the BRELL grid operated by Russia and connected to that of Continental Europe, via a Lithuania-Poland connection.

A set of four 50MW BESS projects owned by state-owned vehicle Energy Cells, deployed by it and system integrator Fluence for TSO Litgrid, helped the country manage the ‘island’ mode between the two parts of the process. (That project is probably the reason for the ‘private’ aspect of E energija’s claim.)

In late 2024, the EU approved a €180 million (US$188 million) support package for over 1.2GWh energy storage in Lithuania, covering a maximum of 30% of the projects’ capital expenditure costs via a competition auction set to conclude before the end of 2025.

E energija Group is an independent power producer (IPP) which has primarily deployed wind and solar in and around the Baltics to-date.

As Europe’s BESS industry matures, project owner-operators are taking on more control – and risk – when it comes to procuring technology and services for their projects.

Energy software and consulting group Ascend Analytics CEO Gary Dorris discusses changes to ancillary services in the Electric Reliability Council of Texas (ERCOT) market and what asset optimisers need to do to stay ahead of the curve.

Latvia state-owned utility and power generation firm Latvenergo intends to deploy 250MW/500MWh of BESS in the next five years.

Longroad Energy has secured a power purchase agreement for one of its hybrid solar and BESS projects in California with Marin Clean Energy.

Germany is currently the “hottest market in Europe today from a development perspective,” according to battery storage developer-investor BW ESS.
