How the 215kW Energy Storage System solves frequency deviation, high peak-demand rates, and freezing operation constraints.
Finland's electrical network, operated by Fingrid, faces rapid variations in wind-power supply alongside high consumption peaks during freezing sub-zero winter spells. Under extremely cold conditions, grid load peaks sharply while standard batteries lose capacity. Our 215kW system incorporates an active liquid thermal management system (TMS) with dual-direction heat pumps, keeping the lithium iron phosphate (LiFePO4) cell temperatures within the optimal 15°C to 30°C range, even when external temperatures plunge to -40°C in Northern Finland.
Finnish commercial and industrial entities can turn their BESS storage into a reliable revenue stream by participating in Fingrid's Frequency Containment Reserves (FCR). The fast millisecond response time of our 215kW system makes it perfectly suited for FCR-N (Normal state disturbance) and FCR-D (Disturbance recovery) operations. By discharging power instantly to balance frequency drops, operators can generate substantial auxiliary revenue while protecting their local operations from voltage drops.
Industrial companies in major cities like Tampere, Oulu, and Espoo are exposed to expensive peak-demand transmission charges. Using peak-shaving control scripts run by our local energy management systems (EMS), our 215kW BESS discharges stored power when facility consumption peaks, allowing operations to keep grid draw below costly peak limits. This decreases base network capacity fees and lowers overall energy bills.

Practical integration scenarios for our industrial-grade storage systems within key Finnish sectors.
Finland has become a major hub for Northern European data centers due to its cool climate and stable business environment. Our 215kW system works alongside large diesel backup generators, providing instant support during outages to ensure uninterrupted service. Its rapid millisecond response time bridges the gap before generators fire up, protecting server halls from dangerous voltage drops.
Wood processing plants operate energy-intensive grinding, chipping, and pressing machinery, which creates severe load fluctuations. Deploying a series of our 215kW units smooths these sudden current spikes, preventing local voltage sag and avoiding utility penalties. In the event of grid failure, these storage units provide enough backup power to safely shut down production lines, preventing damage to equipment.
As electric vehicle use grows across Finland, fast-charging hubs are being set up on key highways like the E75. Connecting a 215kW storage system locally reduces the high-current draw on the grid during peak charging times. The battery stores energy during cheaper off-peak hours and discharges it to cars during high-demand periods, lowering operating costs and avoiding expensive grid upgrades.
How our vertically integrated production facilities in Wenzhou guarantee global delivery reliability and cost advantages.
Located in the heart of Wenzhou's advanced manufacturing zone, we maintain deep, strategic relationships with major lithium raw material suppliers and cell manufacturers. This integrated logistics loop protects us from commodity price spikes and guarantees our access to premium Grade-A cells. Our raw material sourcing and sub-assembly storage remain steady, ensuring smooth production even when global supply chains face disruption.
Every 215kW system undergoes a thorough testing cycle before shipping from our Wenzhou facility. This includes deep-cycle thermal chamber runs, vibration testing, and complete simulated load tests at our CNAS-certified EMC testing center. This strict testing process ensures that every unit arrives in Finland pre-commissioned and ready for direct grid hookup, reducing local setup delays and cost overruns.
Combining industrial power systems with reliable home backups, portable stations, and hybrid solar setups.
As modern life becomes increasingly dependent on electricity, unexpected power outages can cause significant inconvenience for households and small businesses. The solar off-grid power system offers a reliable solution by providing backup energy for homes. This system uses high-efficiency solar panels to capture sunlight during the day, converting it into electricity that is stored in advanced lithium iron phosphate (LiFePO4) batteries. Even during power grid failures, it delivers a steady, clean energy supply to household appliances and essential communication devices.

Technical answers to common integration questions regarding the 215kW energy storage system in Finland.
Our 215kW/430kWh BESS features an integrated liquid thermal management system (TMS) equipped with a dual-direction heat pump and cell-level heating elements. When temperatures fall below freezing, the system uses internal energy or grid power to warm the liquid loops, keeping cell temperatures inside the enclosure between 15°C and 25°C. This active heating prevents lithium plating and capacity loss, ensuring reliable operation at temperatures as low as -40°C in Northern Finland.
Yes, our industrial energy storage configurations are fully compliant with Fingrid's technical specifications for grid connection, including VDE-AR-N 4110/4120 and EN 50549-1/2. They support active frequency containment controls, enabling rapid response under 200 milliseconds to meet Fingrid's FCR-N and FCR-D secondary reserve market requirements.
Liquid cooling keeps temperature differences between battery cells under 2°C, compared to 5°C or higher in air-cooled systems. This uniform temperature distribution prevents local degradation, increases overall round-trip efficiency (RTE) by 3-5%, and extends the battery pack's operational lifespan by up to 20%. It also allows for a more compact system footprint, which is ideal for industrial locations with limited space.
