Lithuania sets up grid-linked energy storage pilot with Siemens in 'post-Soviet' move | Recharge - Recharge

Siemens, its Fluence storage joint venture with US power group AES, and Lithuania’s transmission system operator Litgrid plan to build a first project in the Baltics that links battery energy storage directly to the power grid to help the Baltic nation move away from Soviet-era energy ties towards an integration with EU countries.

The project uses the concept of ‘virtual transmission lines’ (VTL) that places energy storage along a transmission line to inject or absorb real and reactive power, mimicking transmission line flows.

However, high penetration of non-synchronous renewable generation is likely to present power system stability challenges in the areas of frequency, voltage and stability, which storage linked directly to the power grid is trying to mitigate.

The pilot project with Fluence is Lithuania’s first grid-scale battery energy storage system, and will be among the first VTL projects in Europe to be tested.

“VTL is one of the most exciting applications for battery energy storage.
