The project “Energy Efficiency Improvement of the District Heating System in Drobeta Turnu-Severin" is developed and implemented under Joint Implementation (JI) between Denmark and Romania. The project is supported by the Danish Environmental Protection Agency and ROMAG TPP. The JI component was developed by the Danish project developer Grue & Hornstrup A/S working in cooperation with the Romanian engineering and energy services company Energy Serv SA. This project will be the first Joint Implementation project in the Turnu-Severin area related to the rehabilitation of an existing district heating system. 
The project is aiming at reducing the emissions of CO2 by increasing the thermal energy efficiency of the district heating network. It includes rehabilitation of heat substations and change of heat and hot water pipes in the secondary distribution network. 
The project has completed JI development, and was physically implemented in stages during 2007 to 2009 period. 
The Combined Heat and Power (CHP) plant ROMAG TPP produces electricity to the national grid and district heating and hot tap water for domestic and commercial consumers in the City of Drobeta Turnu-Severin. In addition the CHP produces process steam to nearby industrial consumers. 
The district heating system was put into operation in 1967. A majority of the existing heat exchangers at the substations and pipes in the secondary network are obsolete and worn out, resulting in large heat and water losses. To compensate for these losses, the system is permanently supplied with additional cold water. 
The heat distribution consists of a supply and return line, while for the hot water for domestic use, only a supply pipe exists. Due to changes in heat demand and ageing equipment beyond the standard lifetime, large sections of the distribution pipes are oversized and in poor condition, which lead to large amounts of heat and water losses. 
The project activity encompasses the replacement of the existing heat exchangers with modern equipment at the heat substations as well as the replacement of heat and hot tap water pipes with modern pre-insulated piping in the secondary network. This will lead to a considerable reduction of heat and water losses within the system. 
This Joint Implementation project reduces CO2 emissions into the atmosphere through the overall thermal efficiency increase within the district heating distribution network, which leads to a reduced consumption of fuel (lignite and heavy fuel oil) at the CHP plant. 
In this manner the project is expected to reduce fuel consumption at approximately 650,000 tons of lignite and 7,500 tons of heavy fuel oil, respectively during the period from 2007 to 2012. 
The total expected emission reductions from this Joint Implementation project are estimated at 335,000 tons CO2 during the contracted period. 
The proposed project activity will considerably reduce fuel consumption of lignite and heavy fuel oil at ROMAG TPP. Further, a large reduction of local dust and particle pollution from combustion and lignite transportation is a result of the project. 
The project will also improve the quality of heat service delivered to the consumers in terms of a more reliable and efficient heat supply and distribution. The project will furthermore create additional jobs during the construction period of the rehabilitation works. All of this will play a part in strengthening regional development. 
Moreover, the project introduces state of the art technology and will strongly contribute to the local technical capacity development.
