As Europe continues to face electricity price volatility and grid capacity constraints, logistics operators encounter growing challenges in electrifying heavy duty truck fleets. Limited transformer capacity and high grid upgrade costs often restrict the deployment of high power charging stations, directly impacting daily operations. To address this, SCU delivered BRES energy storage systems to German logistics fleets, providing a reliable and cost-efficient alternative to traditional grid expansion.
We have installed a 20ft energy storage container. The solution integrates 1MWh lithium-ion battery capacity with a 625 kW PCS, operating in an AC-coupled, grid-connected configuration alongside the client’s solar installation. This setup enables the site to store an additional 800–1,000 kWh of solar energy per day, energy that would otherwise be curtailed or underutilized, significantly increasing renewable energy consumption on-site.
By acting as a flexible energy buffer, the BRES solution delivers a stable output to EV charging stations, ensuring uninterrupted fleet operations even during peak demand periods. More importantly, it eliminates the immediate need for transformer upgrades, which in Europe can typically cost €150,000–€300,000 and require long approval cycles. Instead, the energy storage system optimizes existing grid access, accelerating deployment while reducing capital expenditure.
From an operational perspective, the solution enables peak shaving and time shifted energy use, allowing the client to charge the battery during low tariff periods or via solar generation, and discharge during high tariff hours. This strategy can reduce electricity costs by 20–30%, depending on local tariff structures, while improving overall energy efficiency.
Energy storage is becoming a key enabler for commercial and industrial electrification across Europe. By combining renewable energy integration, peak shaving, and flexible power delivery, solutions like SCU BRES help businesses reduce energy costs, avoid infrastructure bottlenecks, and transition toward more resilient and sustainable operations, without being constrained by grid limitations.
