Summary

This project is developed as a Joint Implementation (JI) project by Municipal Energy Agency - Rousse in cooperation with local district heating company "Toploficatsia-Rousse SPJsC" (TPP Rousse), Heating Supply Company - Shoumen, Center for Energy Efficiency EnEffect, Sofia and Regional Environment Centre for CEE.

The project aims to optimize production processes and extend the existing district heating network supplied by TPP Rousse in the city of Rousse (see figure bellow). At present the residents in the target area (6 432 flats) are using individual heating equipment/systems for space heating and domestic hot water (DHW) fuelled by electricity, briquettes, wood and diesel. After the implementation of the project, the individual heating equipment/systems will be replaced by district heating system, resulting in the change of energy sources and sources of emissions arising from space heating and DHW in the target area and providing higher comfort of living for the citizens.

Results

Full set of documents ready for validation and approval according to UNFCCC and Bulgarian internal JI procedures. According to developed feasibility study expected results after project implementation are:

The population living in the proposed area will decrease expenditures for space heating and DHW by 50-60% compared with using electricity. Replacing obsolete individual heating systems with district heating system at the end users will improve the overall energy efficiency of end-users and TPP Rousse East.

District heating company: Increasing the heat load of the local district heating company will improve the overall energy efficiency (i.e. less fuel consumption per unit of energy produced). Combined production of electricity and heat, by which heat will be supplied in the project, is a highly efficient technology for energy production. Promoting combined generation of electricity and heat is part of the strategy for efficient use of the primary energy sources and it is in compliance with national priorities. Application of modern and highly efficient insulation for district heating network will minimize heat losses in transmission and distribution.

There are obvious advantages for the Municipality from implementation of the project: municipal buildings would get better quality of the heating service; residents would live and pupils would study in healthier indoor air quality environment; less expenditure for energy and healthcare services could be expected. Additional effect in terms of employment is envisaged: more than 200 employees during construction and 15 employments for maintenance of the new network.

The table below describes expected reductions of the GHG by the project activity until end of the first commitment period of the Kyoto protocol. It is expected, using JI mechanism, some of the project activities to be financed through selling all or part of reduced GHG.
