Fortum will build a district cooling plant and network in Tartu, Estonia.
Once completed, this will increase the offering for customers in Tartu with another product in addition to heat and electricity, which is currently produced by Fortum's local combined heat and power (CHP) plant. The first customer, who has
already signed a contract with Fortum Tartu, is planned to be connected to the
network already at the end of 2015.
The total cost of the investment is EUR 5.7 million
including a new cooling plant with the capacity of 13MW and its connection to
the customers with a 1.3 km long network. The plant will be located next to the
Emajõgi river, which allows for the use of river-cooled chillers, which are
part of a high performance production solution. Low water temperature during
winters is used for natural cooling, which ensures high energy efficiency.
”With its dense population and
high cooling demand, downtown Tartu is a very suitable area for the development
of district cooling. There are plenty of businesses and shopping centers, which
all need cooling,” says Margo Külaots, Country Manager, Fortum Estonia.
Fortum and district cooling
Fortum has long experience in the
field of district cooling both in Sweden and Finland. For example, in
Stockholm, Sweden, Fortum has 9,500 business and residential customers in district heating and cooling. The over 200 km long
district cooling network in Stockholm is larger than
the district heating network in Tartu.
Currently, in Tartu, there are approximately 800 business customers and
75,000 residential customers in district heating in Tartu.
District cooling has several advantages compared to other
alternatives available on the market. Connecting a property to the district
cooling network removes the need for refrigeration equipment and additional
cooling units on roof tops. This frees up large amounts of space and brings
significant savings for the property owners. District cooling is efficient,
reliable and environmentally sustainable as it is based on durable industrial
refrigeration and reduces CO2 emissions by 70% (6000 ton/year) as compared to
the alternatives that can be used.
