LONGi delivers its first Dutch C&I storage project in the Netherlands

With the commissioning of its first commercial and industrial (C&I) battery storage project in the Netherlands, LONGi has put the OmniCube A215 to work in a demanding real-world setting of a high-traffic electric-vehicle charging site in Schiedam, in the Rotterdam region of the south-western Netherlands. The system keeps the site running reliably through its busiest charging periods without adding extra load pressure to the power grid.

The installer, E-Wndr, oversaw the site installation that runs multiple EV charging points alongside a high daily electricity load. At peak charging times the total on-site demand approached, and occasionally exceeded, the contracted connection capacity, leaving the business exposed to the risk of overrunning its agreed peak. Rather than wait for a costly grid-connection upgrade, the operator deployed one OmniCube A215at 215 kWh / 105 kW, storing energy during quieter periods and releasing it during peak spikes, easing the burden on the grid.

For LONGi, the project is another step from solar-module manufacturer towards its LONGi One vision of integrated solar-plus-storage, and a demonstration that LONGi’s energy storage solutions like the OmniCube A215 can be adapted to existing projects with minimal costs and operational disruptions.

A congested Dutch grid and surging EV demand are turning on-site storage into apractical necessity

The Netherlands has the densestpublic charging network in Europe, with more than eleven charge points per 1,000 inhabitants, the highest per-capita rate on the continent. This rapid adoption of EVs and charging infrastructure has added pressure to the Netherlands’ already congested grid, making capacity a bottleneck to further expansion. Grid congestion has emerged as one of the central challenges to bothenergy security and the wider energy transition.

Grid capacity constraints are most prevalent in the densely populated west of the country, where connection queues are long. For sites that cannot simply secure more grid capacity, on-site storage offers a functional alternative, shifting consumption away from peakhours.

Dutch policy is increasingly built to reward this kind of flexibility. In 2025, transmission operator TenneT moved toward a large-scale rollout of time-dependent transmission right (TDTR) contracts, which give flexible users, such as battery systems, access to off-peak capacity in return for accepting limited curtailment and can lower grid tariffs by up to 65 percent. This signifies that flexible projects that can shift demand away from peak periods are becoming central to how the Dutch system manages capacity.

The OmniCube A215 combines storage, conversion and control in a single integratedunit

The OmniCube A215 is a modular C&I storage system delivering 215 kWh of capacity and 105 kW of power on asafer lithium-iron-phosphate (LFP) platform. Because the battery, inverter andenergy-management system are integrated into one enclosure, it connects directly to a standard 400 V three-phase supply and can be added to an existing site without redesigning its electrical infrastructure.

At its core is LONGi's Intelligent Cell Connection System (iCCS), which reduces internal wiring by up to 80percent and allows every cell to be monitored individually, so thermal irregularities are caught early. The architecture is built to scale: up to ten units can run in parallel, taking a deployment from around 100 kW into the megawatt range as demand grows. Integrated protection and an aerosol-based fire-suppression system, alongside compliance with international IEC and UL standards, support straight forward permitting and long-term insurability.

For a live charging site, the systemhad to slot into a working operation, manage real peak loads safely, and leave headroom to expand as charging demand keeps climbing.

Schiedam offers a repeatable blueprint for EV and C&I sites across the Netherlands

Thousands of Dutch sites face asimilar tension between rising electrified demand and a constrained grid. TheOmniCube A215's modular design means the same approach can be scaled up or replicated, and the system is compatible with on-site solar and other generation, leaving room for fuller energy-management setups in future.
