Dnipro is an administrative and cultural centre in the Dnipropetrovsk Oblast and one of the major cities of Ukraine. It is located 470 km southeast from Kyiv. The area of the city is 405 km2 and its population is about one million people. Dnipro is one of the most important industrial centres of Ukraine with more than 1,100 big and medium enterprises.
The heat supply of Dnipro includes centralised and individual heating systems. District heating is provided to residential buildings (approximately 63% of the residential buildings in the city), public and commercial facilities. Dnipro has four utilities of district heating service: “Dnipropetrovski miski teplovi merezhi”, “Teploenergo”, “Komenergoservis” (involved in this study) and “Teplotrans”. The Communal Enterprise “Komenergoservis” DCC serves 18 central heating stations (CHS), 5 pressure reduction stations and operates 316 km of heating networks.
Dnipro Demonstration Project – overview
The proposed project involves the installation of IHSs in one district of Dnipro. The district concerned is served with heat through the CHS-6D and all the connected buildings will be equipped with IHSs which makes it possible to close down both the CHS and the distribution pipelines for domestic hot water. The investment will significantly reduce the energy use and water losses in the project area which will reduce the use of fossil fuels in the combined heat and power plant that supplies the buildings with heat. These parts of the district heating system will be converted to a demand driven system.
The proposed project is interesting from a demonstration point of view as the introduction of IHSs in the area will increase the quality of heat delivery to the connected buildings and the system will be converted towards a more sustainable demand driven system.
Dnipro Demonstration Project – details
The initial project areas are located in the eastern parts of the city of Dnipro. Several of the districts are quite large and not suitable for the size of this project. However, three districts were identified as appropriate in size: CHS-6D in Donetske Avenue 150K, CHS-7 in Berezinska Street 20K and CHS-3 in Rotorna street 20K. The two districts CHS-6D and CHS-7 are indicated in the upper “project area” in the following figure while the lower “project area” is referring to district CHS-3. After further discussions, the project considers the modernisation of the area served from CHS-6D.

Specifics of the Dnipro project include:
- Individual Heat Substations – Introduction of 13 IHSs in all buildings in the district served by CHS-6D.
- Network replacement – approx. 1,000m of new distribution pipelines in the district served by CHS-6D, convert the present pipe systems.
- Close down of CHS-6D.
The proposed investment is EUR 373,000 with a simple pay-back time of 7.4 years. The proposed financing plan is as follows:
- Total loan – EUR 149,000 (40%)
- Total grant – EUR 148,000 (40%)
- Total Dnipro local contribution – EUR 76,000 (20%)
The project is expected to benefit the local community by:
- Saving 2,850 MWh heat per year (31% saving from the baseline*)
- Saving 55 MWh electricity per year (85% saving from the baseline*)
- Saving 1,010 tonnes CO2 per year (31% saving from the baseline*)
*Baseline is estimated for the networks in question only (not the entirety of the district heating in Dnipro) for the case of no-project activity.
The project has been cancelled. The project has been rejected by the city as the installation of IHSs was considered inexpedient for the district heating company.
