The monitoring system of the relevant plants was realised with telecontrol units of different manufacturers. Renovation of the outdated telecontrol systems was started in 2008.

Connection to the on-site central control system was made using redundant FW-5000 telecontrol interfaces and different transmission media such as switch network, dedicated lines, GPRS and LAN. Most of the new telecontrol systems were supplied already built into wall-mounted and free-standing switchgear cabinets. All the configuration, installation and commissioning work was carried out independently by enwor employees. Some of the water and district heating stations also have a Modbus interface for linking lower-level systems.

Approximately 118 net-line FW-4, FW-5 and FW-50 telecontrol systems are currently in use.
