Limiting urban system’s heat losses

Bacău in north-east Romania is thoroughly updating its district heating system, to deliver better energy efficiency for more than a third of the town’s inhabitants and a cleaner environment for all.

Additional tools


Scheduled work includes rehabilitation of existing urban-heating plants and heat-supply networks, including the installation of a combined cycle unit in one plant. Once this is completed, the town will be fully compliant with the EU environmental legislation covering such systems.

Reducing air pollutants

Bacău’s current district-heating system supplies more than 37 % of its 177 000 inhabitants, plus most of the town’s public institutions and service sectors. This five-year project seeks to improve the efficiency of local heating plants, which suffer from excessive heat losses, as well as the efficiency of related transport and distribution networks. A further goal is to improve local air quality, which will naturally benefit people’s health.

The town already has an action plan to tackle harmful emissions – such as sulphur dioxide (SO2), nitrogen oxide (NOx) and dust – from its district-heating system. This project will therefore meet Bacău’s goal of becoming cleaner and greener, while bringing it in line with European standards on emissions.

Specific measures include retrofitting a hot-water boiler in plant two, and retrofitting two transport pumps as well as the distribution network. These are all designed to boost energy efficiency. Plant one will also be fitted with a modern combined cycle unit: this will increase energy efficiency and reduce harmful emissions by cutting use of brown coal. Lastly, the project will oversee the closure of the slag and ash deposit, which will reduce corresponding pollution.

Enhanced energy efficiency

Once completed, the project will have made a range of improvements to local heating plants, including retrofitted boilers and pumps. The 66 700 inhabitants connected to the district-heating system will benefit directly from the project. For the wider municipal population, there will be significant benefits over time thanks to improved air quality and health conditions – helping to make the area a more attractive place for inward investment.

The project will generate 225 jobs during the implementation phase and 60 jobs during the operating stage. A notable improvement in the heating system’s energy efficiency will reduce consumption of primary energy, including fossil resources, thus also contributing to the reduction of greenhouse emissions.

Bacău has plans for further rehabilitation of its urban-heating networks and to go on reducing air emissions, according to the latest EU legislation.

Total and EU funding

The project “Rehabilitation of district heating system in Bacău municipality in order to comply with environment standards on pollution emissions and to increase energy efficiency in urban heating supply” has a total eligible budget of EUR 63 197 300, with the EU’s Cohesion Fund contributing EUR 31 598 600 for the 2007 to 2013 programming period.
