Residents of Tallinn’s Kopli Lines residential district pay more than 40 percent more for heating than other customers on the city’s district heating network, ERR reports. Connecting the district would be technically possible but would cost about €2 million and require the initiative of developer Fund Ehitus.
Tallinn Deputy Mayor Kristjan Järvan said the two heating networks are about 900 metres apart. The city cannot force private companies to sign the technical agreements needed for a connection, he said.
Utility company Utilitas said there are no technical obstacles to linking the Kopli network to the city’s main system. It is ready to discuss options but is waiting for Fund Ehitus, which owns the local infrastructure, to take the initiative.
Fund Ehitus expects heating costs to fall as the district develops. The project’s second phase includes new homes, shops, cafes and a kindergarten. Chief executive Reigo Marosov said more customers would allow the boiler house’s maintenance costs to be shared among more residents.
Residents say they do not want to wait for construction to be completed. Pille Jansen Koppel, a board member of Kopli Liinid, said about a quarter of heating costs comes from rent for the boiler house and heating infrastructure. SW Energia pays that rent to Fund Ehitus, and the cost is added to customers’ bills.
Tallinn city council Social Democrat Joosep Vimm estimated that residents paid about €85,000 more for heating over the past year than they would have if connected to the city network. He said Tallinn should play a more active role in finding a solution, partly because the city owns a third of Utilitas Tallinn Soojus.
Heating in Kopli Lines costs €109.65 per megawatt-hour. The city’s main heating network charges €77.82 per megawatt-hour through November 16.
In October, ERR’s Russian-language news site reported that the city was willing to discuss connecting Kopli Lines to the main heating network, but no timeline or prospects for carrying out the project had been set.
