Completed Projects
Poltava
District Heating Utility "Poltavateploenergo" has implemented a project, which was completed in autumn 2015. The project area includes a boiler house supplying heat and hot water to ten, mainly residential buildings but also a children's hospital and a school.
The project concept was to:
(I) Introduce demand driven heat supply to customers, by installing individual heat substations with control of heat supply in relation to outdoor temperature in all buildings connected to the boiler house.
(II) Reduce losses in the heat distribution system by replacing all district heating pipelines in the area.
(III) Replace the old boilers with new efficient condensing boilers with capacity to adapt the heat production to the heat demand.
Project results and achievements
The project in Poltava demonstrates best practices in technical design, procurement and project implementation in a small-scale project. For the city of Poltava installation of Individual Heating Substations is a new application of district heating technology. The Individual Heating Substation configuration used in the project is substantially simpler and more cost effective than the configuration previously normally used in Ukraine. Installation of the IHSs demonstrates a complete conversion to a demand driven system.
The replacement of old district heating pipelines is done with flexible type pipelines to demonstrate efficient pipe laying in narrow areas. Further reduction of investment costs could be achieved by modern pipe sizing accepting higher pressure drops.
Customers of the district heating company, residing in the buildings with the new IHSs, are benefiting from improved supply of domestic hot water and improved indoor climate.As a result of reduction of losses and improvement of production efficiency, gas savings of more than 30% has been achieved. The project is also profitable for the utility with an expected pay-back time of less than eight years.

Second DemoUkrainaDH in Poltava
A second DemoUkrainaDH project in this city, includes, installation of a flue gas condenser for an existing boiler with a capacity of 58 MW, a new stack (height 57 metres) and an automatic control system. The use of a flue gas condenser is expected to reduce the gas consumption for the boiler with between 6% and 12%. The background for a second project in the same city is the fact that the introduction of a flue gas condenser at a relatively big, already existing gas boiler is expected to provide specific demonstration value and potential replicability. Furthermore, the potential of increasing the savings over time by actively working for reduced district heating return temperatures from the customers is interesting and will give an incentive for measures such as installation of IHS and improved control system at buildings.

Update February 2017
Оleksandria
The demonstration project in Oleksandria was completed in autumn 2015. The project includes:
- Installation of new gas boilers in a former central heating substation. The new boilers are condensing type with high efficiency (>100 %) and capacity of 7.5 MW, which will supply heat to an area with high-rise apartment buildings, with in total 1,800 apartments, in the centre of the city.
- Replacement of district heating pipelines and obsolete and deteriorated pipelines in basements of the buildings.
- Installation of a small-scale CHP for production of electric energy for the needs of the boiler house.
Reconstruction of the CHS-room into mini-CHP
Project results and achievements
The project in Oleksandria demonstrates - in a centrally located district - how the district heating service level can be increased. The new system will give a better controlled supply of space heating for the public and private users of the district heating services, leading to improved indoor climate and a higher degree of customer satisfaction. The new system will also be able to supply the buildings with domestic hot water all year. This will increase the comfort - an important achievement especially for kindergartens and schools.
The project in Oleksandria has a high replication potential as the district heating company in Oleksandria alone has 22 more central substations. Continuation of the modernization could stop and roll-back the on-goin disconnection of customers from the district heating system. This will in turn lead to increased energy efficiency for the city.
As a result of reduction of losses and improvement of production efficiency, gas savings of more than 30% and electricity savings of 20% are expected. The project is also profitable for the utility with an expected pay-back time of less than four years.

Kamyanets-Podilskyi
The demonstration project in Kamyanets-Podilskyi was completed in autumn 2015. The project included:
(i) Installation of 22 modern prefabricated individual heating substations (IHSs) with brazed heat exchangers, downsized control valves and heat meters in residential and public buildings supplied from a boiler house at Zhukova Street
(ii) Retrofit and balancing of building internal heating systems (iii) Installation of frequency controlled network distribution pump for variable flow.
Better indoor climate in a Kindergarten
Project results and achievements
The project in Kamyanets-Podilsky demonstrates best practices in technical design, procurement and project implementation in a small-scale project. For the district heating company it was the first experience with installation of IHSs and the start of a development to install IHSs in all the buildings of the city. As a result of the project a significant proportion of the heating system has been converted to a demand driven system. The 4-pipe system was replaced by a 2-pipe system, with equipment for controlling the heat supply according to the real heat demand. For customers the indoor climate improved and the quality of tap water preparation in each building increased significantly. The district heating company conducted an awareness campaign to improve the customers’ understanding of the new system and to inform them about the way in which their individual behaviour influences energy consumption (e.g. use of hot water, control over overheated parts of buildings). The combination of efforts for introduction of a demand driven heating system and reduction of losses is expected to bring gas savings of more than 30% and electricity savings in the range of 40%. The project is also profitable for the utility with an expected pay-back time of less than 5 years.

Vinnytsia
The demonstration project in Vinnytsia was completed in spring 2015. The project area 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
(i)Introduce a demand driven heat supply to customers, by installing individual heat substations with control of heat supply in relation to outdoor temperature.
(ii)Reduce losses in heat distribution by replacing heat distribution pipelines in the area, in total 1.5 km (double pipe).
(iii)Closure of the inefficient smaller boiler house in the area, which was made possible due to the reductions of energy demand.
Project results and achievements
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 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. All in all, energy savings in the order of 30 % are expected. Apart from the improved services to the about 2100 residents living in the buildings, the project is profitable for the utility, with an expected pay-back time of about 5 years. The use of modern design and implementation practices was essential for the project outcome, challenging established norms, practices and ways of thinking.

Ivano-Frankivsk
The demonstration project in Ivano-Frankivsk was completed in 2016. The project includes:
- commissioning of one boiler house and connection of the heat load to another boiler house.
- Introduction of demand driven heat supply to customers by installing individual heat substations (IHS) with control of heat supply in relation to outdoor temperature in 38 buildings in the interconnected heating area.
- Installation of variable speed network distribution pumps.
- Conversion from 4-pipe supply system to 2-pipe system and substantially reducing the heat losses.
- Installation of a SCADA system for collection and presentation of operation and consumption data for each IHS.
Successful procurement, well below budget, has allowed for extending the project with 21 IHS that have been installed in buildings in another heating area, supplementing planned modernisation efforts to be financed by EBRD.
Project results and achievements
The project in Ivano-Frankivsk demonstrates best practices in technical design, procurement and project implementation in a small-scale project. By installing individual substations throughout the whole area, the district heating system is fully demand driven and the district heating service level could be increased significantly. The improvement of the system will give a better controlled supply of space heating for the users of the district heating services, leading to improved indoor climate, supply with domestic hot water all year and a higher degree of customer satisfaction.
After completion of the project financed by EBRD, the newly installed SCADA-system will make it possible to combine operation of two boiler plants in the same system, which is a remarkable demonstration effect within the framework of DemoUkrainaDH.
As a result of reduction of losses and improvement of production efficiency, gas savings of around 30% and electricity savings of 50% are expected. The project is also profitable for the utility with an expected pay-back time of less than three and a half years.
