Europe’s electricity market is becoming more volatile, making energy storage Europe solutions increasingly important for industrial users. Factories are facing high electricity costs and wider price differences between peak and off-peak hours. In the EU, non-household electricity prices averaged €0.1837/kWh in the second half of 2025. At the same time, negative electricity prices are becoming more common as solar and wind power continue to grow.
For factories, this brings both cost pressure and new opportunities. Electricity is expensive during peak production periods, but it can be much cheaper, or even negative, during low-demand or high-renewable hours. Facilities that can store energy and adjust when they use electricity are better positioned to reduce costs, making a reliable factory energy storage solution increasingly valuable.
SCU has provided energy storage systems to multiple factories and local facilities in the Netherlands. One recent project uses a GRES energy storage system with a 75 kW PCS and 50 kWh battery capacity. As an industrial energy storage system, it is mainly used for peak shaving, low-price charging, and selling electricity back to the grid when market conditions are favorable.
The system charges during off-peak or low-price hours and discharges during high-price production periods. This peak shaving energy storage application helps the factory reduce maximum grid demand, lower peak electricity costs, and make better use of price fluctuations in the Dutch electricity market. For sites with solar PV, EV charging, or variable production loads, energy storage can also improve overall energy flexibility.
If the 50 kWh battery provides around 45 kWh of usable energy and operates one cycle per working day for 300 days, it can shift about 13,500 kWh of electricity per year. With a peak/off-peak price spread of €0.10–€0.15/kWh, this can create about €1,350–€2,025 in annual energy arbitrage value.
Peak shaving can bring even greater savings. If the system reduces factory peak demand by 50 kW and the demand-related cost is valued at €10–€15/kW per month, the annual peak shaving benefit can reach about €6,000–€9,000. With additional grid export or flexible operation revenue, the total annual value could reach approximately €8,350–€13,025.
SCU’s energy storage solution helps factories move from passive electricity consumption to active energy management. By combining peak shaving, low-price charging, and potential grid revenue, SCU provides industrial customers with a practical way to reduce energy costs, improve resilience, and capture new value in the commercial energy storage Europe market.
