UAB „Šakių šilumos tinklai“ (Šakiai District Heating) has been using UAB Energy Advice digitalisation services since 2019. With a platform EA-SAS Heating a digital twin of existing district heating network was created. Digital district heating network management allowed us to move to low supply temperature operation. Now we can efficiently plan network expansion and maintenance; all our information is accessible remotely through web browser. Our experience shows that Energy Advice is a trustworthy partner providing quality services and supporting our company in reaching digitalisation and energy saving goals.
