Intelligent energy management system for shopping centre

Shopping centres require an enormous amount of energy. Providing air-conditioning over summertime in particular drives energy costs through the roof. In order to bring these costs under control, the management of the Pirita Keskus Shopping Centre in Tallinn decided to invest in a 54-kWp PV system.

What do you think about a 95% self-consumption rate?

Thanks to intelligent energy management, the shopping centre can harness 95% of the electricity it generates. As all the necessary data communication flows – such as WLAN, Ethernet and energy management – are integrated into the Fronius Eco as standard, there are no additional costs, which has a positive impact on the overall investment.

“We trust products from Fronius. We have never had a problem with any Fronius component – unlike devices from some other manufacturers,” says Criss Uudam from AU Energiateenus OÜ.
Size of installation 54 kWp
System type Roof-top installation
