Enersense has been appointed by Latvian energy storage developer Liepaja ESS to build a Battery Energy Storage System (BESS) park and its 110 kV grid connection in Southern Latvia, covering all civil works, equipment installation and a new high‑voltage link to the AST Grobiņa substation.
The deal marks Enersense’s first full‑scope BESS delivery, drawing on the company’s operational experience with battery systems in Finland.
“While we have previously participated in several projects related to BESS, this time we are taking full responsibility for the entire delivery – from site preparation to the final grid connection of the BESS,” said Arnis Odiņš, Managing Director of Enersense in Latvia. He added that growing renewable penetration is increasing the importance of storage for grid stability.
The contract covers all civil and electrical works, including site preparation, earthworks, foundations, equipment installation and assembly. Enersense will also construct the BESS control building, install cable networks, and deliver grounding and lightning protection systems.
A new 110 kV cable line will link the site to the AST Grobiņa substation, alongside installation of a 110/33 kV transformer and associated primary equipment. Final works include access roads, fencing and drainage. Construction begins immediately, with completion scheduled for 2026.
“We appreciate the trust placed in us by the client. Enersense aims to be a trusted lifecycle partner for battery energy storage companies. This agreement is a strong demonstration of that ambition in practice,” Odiņš said.
The contract is valued at around EUR 7 million. The project is due for completion in 2026.
