Tallinna Soojus, City of Tallinn and Eesti Energia, Estonia
District heating rehabilitation project
Total installed capacity 2016 MW and total heat load 1651 MW, trench length of the main DH network 320 km and the secondary network 150 km. Number of consumer substations 3 890.Rehabilitation study 1993-1994
Implementation phase: constant flow was changed
to a variable flow mode, separation of primary
and secondary networks. Replacement of 1051 old
consumer connections, installation of 267 heat
meters, 12 445 line balancing valves, 28 secondary
circulation pumps and 600 control valves in the
existing substations. Installation of O2-analysers
and boiler automation at the Kadaka boiler plant.
Erection of a demineralisation plant with a capa-
city of 300 000 m3/year, installation of side steam
filters at five heat production plants. Installation
of SCADA remote monitoring system and supply of
maintenance equipment, such as maintenance lorries,
pumps and cranes, 1995-1998

New City District Heating and Cooling Projects
Project consisted of five about 1000 MW districtheating systems. All of them also use district heat
to power chilling equipment for air conditioning
in office blocks.
The CHP plants are combined cycle (gas-steam turbine)
power plants.
The total network length is about 350 km.
