The city of Vinnytsia is a regional centre in the Vinnytsia Oblast, located on the river Southern Bug. Its total area is 80 km2 and is the home to 370,000 people.

About 70% of the city population is served by district heating systems. CE VMR “Vinnytsyamiskteploenerho” provides 84% of the city heat supply.

Vinnytsia Demonstration Project – overview

The demonstration project in Vinnytsia includes eleven residential building blocks and a hospital. Heat and hot water to the buildings are provided from two boiler houses. The project concept was to:

  • Introduce a demand driven heat supply to customers, by installing individual heat substations with control of heat supply in relation to outdoor temperature.
  • Reduce losses in heat distribution by replacing heat distribution pipelines in the area.
  • Closure of the inefficient smaller boiler house in the area, which was made possible due to the reductions of energy demand.

Vinnytsia Demonstration Project – details

The project area includes eleven residential building blocks and a hospital.

Specifics of the Vinnytsia project include:

  1. Individual Heat Substations – Introduction of 11 IHSs on Kievska and Talalihina streets
  2. Installation of a new CHS at Griboyedov 3.
  3. Network replacement – approx. 1,500m of heat distribution pipelines in the area.
  4. Close down of the existing boiler house in Kievska Street 82.

The investment amounts to EUR 680 000 with a simple pay-back time of 5 years. The financing plan is as follows:

  • Total loan – EUR 290,000 (42.5%)
  • Total grant – EUR 290,000 (42.5%)
  • Total Vinnytsia local contribution – EUR 100,000 (15%)

The project benefits the local community by:

  • Saving 4,050 MWh heat per year (28% saving from the baseline*)
  • Saving 425,000 m³ gas per year (28% saving from the baseline*)
  • Saving 24 MWh electricity per year (16% saving from the baseline*)
  • Saving 820 tonnes CO2 per year (28% saving from the baseline*)

*Baseline is estimated for the networks in question only (not the entirety of the district heating in Vinnytsia) for the case of no-project activity.

The project in Vinnytsia demonstrates what can be achieved by analysing the district heating system as a whole and by using best practices in technical design and project implementation. By the introduction of individual heating substations and new modern district heating pipelines, the losses are reduced, which in turn results in less capacity demand for heating and hot water preparation. As a result, the heat load could be connected to a more efficient boiler house with excess capacity and an inefficient boiler house could be taken out of operation. Apart from the improved services to the about 2,100 residents living in the buildings, the project is profitable for the utility. The use of modern design and implementation practices was essential for the project outcome, challenging established norms, practices and ways of thinking.

Current status

The project was completed in spring 2015.

As a result of competitive procurement, the following suppliers were selected:

  • Individual Heating Substations, “Ukrinterm” LLC, Ukraine
  • District heating pipelines, “Energoresursinvest” LLC, Ukraine

All goods were procured, installed and successfully commissioned.
