EPC:

NYAB

OWNER:

FRV AMPTANK

The Background

The battery system has a power output of 30 megawatts and a capacity of 60 megawatt-hours. Sungrow is the world’s leading manufacturer of battery energy storage systems, with a mission to bring clean energy everywhere – including in the northernmost regions of Finland.

The Solution

Located near the newly commissioned Fingrid Simojoki substation in Lapland, the site will initially house 26 Sungrow's PowerTitan battery arrays based on lithium iron phosphate (LFP) cells, delivering 60 MWh of capacity. The project covers 0.4 hectares and will play a vital role in stabilizing Finland’s growing renewable energy grid.

The Impacts

The solutions help stabilize the power grid as more renewable energy sources, such as wind and solar, are integrated into Finland’s electricity network.

“We chose Sungrow for its proven reliability—both technical performance in Simo’s challenging Northern Finland climate and long-term support through maintenance, servicing, and competitive packages. Our decision was based not on price alone, but on a careful comparison where Sungrow’s reliability and service stood out.”

Hannu Koivusalo Chairman, AmpTank

“Our pre-assembled containerized batteries enable fast installation, using safe, durable lithium iron phosphate with liquid cooling for high efficiency and long lifespan. Backed by over 40% of our workforce in R&D, Sungrow designs products for demanding conditions and is proud to deliver one of the world’s northernmost battery power plants with our customers.”
