The rehabilitation of the district heating system in Iasi municipality

In an effort to bring the district heating system in the Iasi municipality in line with EU requirements, this project will rehabilitate the existing urban heating plants and heat supply networks.

As well as decreasing SO2, NOx and dust emission concentrations from the heating system (which currently exceed authorised levels), the project will also improve energy efficiency in the heating plants and the transport and distribution networks.

Raising the standard to meet EU requirements

This project is part of an overall action plan for the municipality which aims to reduce emissions and rehabilitate networks. The existing district heating system in Iasi supplies more than 158 000 inhabitants, representing 51% of the population, as well as most of the public institutions and service firms.

In concrete terms, the project consists of a number of key actions, including: equipping the district heating system with upgraded production technologies by retro-fitting three hot water and one steam boiler in two plants to reduce NOx emissions; installing a desulphurisation unit in the second plant to reduce SO2 emissions; and installing a dry ash collection system to reduce the quantity of slag and ash deposit. In addition, transport pumps in both plants and in the transport network will also be retro-fitted in order to increase the energy efficiency of the system.

These actions should bring the infrastructure in line with relevant environmental EU legislative requirements and EU policy for reducing the air pollution. The improved heating system will be operated by CET Iasi SA, entirely owned by Iasi municipality.

Boosting the economy while reducing emissions

More than 158 000 inhabitants, most of the municipality’s public institutions and its service firms will benefit from this project. Overall, it will contribute to improving air quality in the area and health levels among the population.

From an economic point of view, it will contribute to making Iasi a more attractive place to invest in and will lead directly to the creation of 197 jobs during the implementation phase.

In terms of environmental benefits, the project will contribute to tackling climate change by sharply reducing SO2, CO2, NOx and dust emissions from the heating system. Additionally, improved energy efficiency in the heating plants and networks will reduce the consumption of primary energy and therefore contribute to a reduction in greenhouse gas emissions.
