Croatia’s power company HEP will finance the project of revitalisation of 69,5 kilometres of hot water network in the city of Zagreb with the help of European Union funds.
“When we speak of this project, the deterioration of hot water network in the City of Zagreb is the reason of big urbanisation as well,” said the Minister of Regional Development and European Union Funds, Nataša Tramišak. “In the following program period, between 2021 and 2027, within given parameters and guidelines for greener Europe, we will certainly support the development of such projects.”
Upon completing this project worth around 700 million kuna (92.7 million euros), the supply to 100,000 households in Zagreb will improve.
“This is an extremely important project which will ensure reliable and continuous heat energy supply to the citizens of Zagreb,” added Frane Barbarić, HEP’s President of the Management Board. “This is the biggest HEP’s project so far and it is currently one of the biggest projects in Croatia, co-financed from European funds. […] A highly efficient facility for the generation of electricity and heat energy, which will be put into operation in 2022 will contribute to a better heating service in Zagreb.”
More than a half of the existing hot water network of the city of Zagreb’s central heating system was constructed between 1962 and 1995, using what is now considered obsolete technology of classical steel pipe laying into a concrete open trench. The high water pipes laid in such a way are subject to external influences, such as a high level of groundwater, possible pipe leakage and penetration of rainwater, which can cause the deterioration of hot water pipes and the formation of corrosion leading to increased heat losses, a higher number of pipe ruptures and the interruption in heat energy supply.
The reduction of heat energy losses will result in the decrease of heat energy generation and consequently in the decrease of pollutant emissions into the environment. It is predicted that two years after Project implementation, in 2025, the CO2 emission will be reduced by 11,104 tonnes, in comparison to the condition before revitalisation.
