On-premises Data Centers have constant high energy demands, they represent an olways-on load at buildings energy balance level. By separating such a load in behind a microgrid system with storage and photovoltaic generation, important CO2 reductions could be achieved. This paper presents the results of such an implementation analyzed from a technical and economical point of view. The pilot installation is analized based on a 3-year data set, measurements consisting in: consumption, PV production, imported energy and storage operation. The pilot achieved for 2017 a 59.66% PV energy coverage from its total usage, thus a financial economy of estimated 3300 Euro from the energy bills. Based on the simulation results the Return of Investment is at the end of the operational lifetime of the installation considering no state incentives nor energy export sold back to the grid. A total of 22.4 T/year CO2 emissions are avoided.
