Discover how it works

Enabling the integration of renewables and electric vehicle charging stations

xStorage Buildings enables the Catholic University of Lille in France integrate a renewable energy production source and maximize its consumption on the campus. The xStorage Buildings system also stores the unused energy which is then redistributed during peak periods or when re-charging an electric vehicle. The system is used to power three electric vehicle charging stations. This represents six charging points with 132 kW of consumption at full load. This brings a great modularity and a flexibility with regards to the electrical grid.

Ensuring back-up power supply and peak shaving while using more self-generated solar energy

The Bislett stadium in Norway wanted to invest in an energy storage solution that would enable them to shave peaks in energy consumption and usage, utilize the solar production in a smarter way and ensure there is a back-up power supply for the stadium and the events they host. The xStorage Buildings system installed at the Bislett stadium includes a 100-kW power conversion system and three racks with 30 Eaton battery packs made up of second-life Nissan LEAF battery modules. This is a great example of circular economy.

Build resiliency

The xStorage Buildings system can improve resiliency and maintain power quality. This is an important criteria for commercial and industrial buildings which cannot risk power outages. As the energy requirements of these facilities continue to expand in future and local networks have more distributed energy generation connected and clusters of EV charging, the ability of an energy storage system to provide resiliency becomes a valuable benefit.

Optimize energy

How to use electricity more efficiently is an increasingly important issue for many types of commercial and industrial buildings and facilities, but especially those with peaks in demand since these can incur even higher costs. Peak demand charges and fees can be avoided by investing in an xStorage Buildings energy storage system for peak shaving.

Go green

Installing xStorage Buildings enhances overall sustainability and reduces CO2 footprint, limiting the deployment of diesel generators. The system also enables the increased consumption of renewable energy if connected with on-site wind and solar PV installations. the microgrid at the Wadeville facility in South Africa includes an xStorage Buildings system and saved 11,812 Metric Tons CO2 in a year.

Lower total cost of ownership

Commercial and industrial buildings owners and operators need to consider future energy requirements as well as any potential opportunities for revenue generation. The xStorage Buildings system enables them to participate in demand response programs and frequency regulation. The system is modular and scalable to meet future demand and energy needs, taking advantage of lower cost lithium-ion batteries.

Rely on the right partner

Eaton is a power management leader with a 100-year experience in supplying and installing power distribution, uninterruptible power supply and back-up equipment. This degree of capability and knowledge is crucial for understanding how the energy storage system integrates and operates within existing power distribution infrastructure, and how the system will provide energy resiliency in any event, protecting the bottom line. We ensure the system meets the highest electrical safety regulations and standards in Europe and at national levels. We provide peace of mind from the design, installation, commissioning to the operational phase of the system with our servicing and maintenance agreements.
