Eaton Energy Storage System Helps the Catholic University of Lille in France Move Towards a Zero Carbon Future

Location: “Eaton provided Background Challenge Catholic University of Lille, France Founded in 1875, the Catholic The Catholic University of Lille us with a solution University of Lille has 30,000 wants its entire campus to students spread across five be zero carbon for its energy Challenge: that increases our faculties and 18 colleges and consumption by 2035 and wants institutes on its historic campus, To provide an energy storage consumption of self- to achieve this by 2021 for one of system that helps the university and in more than 20 cities in its buildings called The Rizomm. France and globally. become a zero-carbon campus generated renewable As part of this program, the by 2035. Engaged in energy, economic building uses innovative solutions power that is reliable and social transition since the to enable this transition and Solution: and could adapt to our turn of the century, the university encourage best practice for launched its Live Tree program the university and the wider Eaton xStorage Buildings particular needs. Using in 2013. Working with the region community. The Rizomm enables the university to store its Hauts-de-France, researchers, building already has 1200m2 renewable energy produced by this system as part local people and businesses, of photovoltaic panels that its 1400m2 of photovoltaic panels Live Tree aims to accelerate the generates 194 kWp of its own and use it to power the building or of our overall energy energy, ecological and economic renewable energy and the charge electric vehicles and thus transition needed for a more reduce carbon footprint. HEI building has 200m2 of management plan, sustainable future in the Vauban- photovoltaic panels generating our ongoing goal is Esquermes area of Lille. 28kWp. This provides power Result: to the building and also to the As part of this program the six-electric vehicle charging points The building has saved 174 Kg to further reduce our university has been renovating at the university. of carbon operating through carbon footprint for its buildings to limit its carbon the winter and early spring footprint and make them a model The challenge the university months. This saving will increase the entire university for good practice and places faced was how to maximize its substantially as the university where new technology use of this renewable resource to learns about its consumption campus.” is implemented. further reduce its carbon footprint patterns and uses the system at Grégory Vangreveninge, Technical and its reliance on the national Talking about the initiative times of national peak demand, grid at times of peak demand, when coal and gas fired stations Manager - Yncréa Hauts-de-France Grégory Vangreveninge, Technical when it uses gas and coal-based supply the extra capacity needed Manager for Yncréa Hauts- generation to top up supply. by the grid. de-France which is a member institution of the program says, Any energy storage solution “with the Live Tree program we that it selected had to fit it in aim to immerse our students with its space requirements for in a scientific and cultural installation and also with the program that will help them act university’s energy management responsibly throughout their system so that it could be personal and professional lives.” optimized as part of an overall energy-efficient system for the building.

Solution sources used to provide additional capacity at times of Eaton worked with the University peak demand. By understanding to install its xStorage Buildings these demand patterns and energy storage system. The also its own usage needs, the system consists of two Eaton university aims to use more xStorage Buildings power power from its own renewable conversion systems (40 kW sources and storage capacity to discharging / 20 kW charging make it less reliant on fossil power) and 25 new battery packs fuel-based grid power when with a capacity of 10 kWh each. demand is at its peak. The university chose the Eaton Researchers and PhD students xStorage Buildings system are working on the university’s because it was flexible and easy energy transition program to to install within the allocated further improve its energy space since the installers could efficiency and uptake of separate the rack of battery renewable energy sources. This packs including the battery includes the development of protection from the power an algorithm to understand its conversion systems. Eaton also patterns of supply and demand worked with the university to and research programs to help them integrate its xStorage increase the supply from its Buildings solution with its energy PV panels. management system by writing and developing custom software. Another benefit of Eaton xStorage Buildings is the ease Result at which it can be expanded to Gregory Vangreveninge store more energy as a result commented: “Eaton provided of increased renewable capacity us with a solution that increases in the future. A further 50 kWh our consumption of self- storage capacity is possible generated renewable power within the existing system. that is reliable and could adapt Grégory Vangreveninge to our particular needs. Using concludes: “Our smart grid this system as part of our overall demonstration project goes energy management plan, our beyond the needs of the ongoing goal is to further reduce university. It communicates our carbon footprint for The real-world results to the whole Rizomm, the HEI and the Hotel Lille area, our ten partner Académique buildings .” companies in the immediate The system had been operating area and beyond that to anyone through the winter and early interested in the adoption and spring months so far and had installation of such technology. already saved the university “Flexible technology that 174 Kg of carbon. The university incorporates renewable expects this to increase production with energy storage, substantially as it begins to such as Eaton’s system, are vital understand its own demands for for us to achieve our zero carbon power and ties this in with the targets at the University of Lille capacity available from the main and beyond that for the nation.” grid to maximize peak shaving. Most power on the French national grid is from carbon neutral nuclear and hydro sources, with coal and gas
