Project presentation
District Heating of Sarajevo City and Sourounding Places from TPP Kakanj
Sarajevo, May 2017
JP Elektroprivreda BiH d.d. – Sarajevo

2. The motives and objectives of the project
The project aims to extend the network of heating energy supply areas to/from Sarajevo and Kakanj.
The motive of the introduction of high-efficiency cogeneration in the product portfolio of the company to improve the environmental aspects of the production of electricity and heat.
Creating conditions for the implementation of the provisions of the Directive on the energy of efficiency (Directive 2012/27/EU).
The implementation of this project would lead to the reduction of CO2 emissions, the most important greenhouse gas that is emitted through the combustion of fossil fuels and other substances made up of carbon in the energy sector, one of the priority sectors of the EU strategy on adaptation to climate change.
The motives and objectives of the project are:
introduction of high-efficiency cogeneration in the product portfolio of the company
Creating conditions for the implementation of the provisions of the Directive on the energy of efficiency (Directive 2012/27/EU).
reducing CO2 emissions and other greenhouse gases
extending the network of heating energy supply

Under the assumption that the version of 300 MWe and 300 MWt of unit 8 will be implemented, and that unit 7 will remain in long-term operation (up to 2040.), it is assumed that the TPP Kakanj will continuously dispose with 600 MWt power, starting from year 2018.
In the meantime, it would be necessary to reconstruct the turbine separation in unit 7, for it to be ready for cogeneration.
* The replacement block (η = 42%) - Technological solution in the planning stage (data according to the preliminary design )
→ annual index of primary energy savings> 10% (based on calculation parameters)

Here we have an overview of the technical characteristics of the hot water pipelines.
Thermal energy from the thermal power plant Kakanj will be ssupplied to the following cities: Visoko, Breza, Ilijas, Vogosca, Sarajevo.
The main hot water pipeline will be 46 km long, and the branche hot water pipeline 39 km.
The management of the complete system is provided via an automatic control of the remote heating system.

* Treated as a separate cost of the project - a separate project.
Operational costs (OPEX)
Supply / heat production
24,31 KM/MWh
Main and brache hot water pipelines*
,00 KM
The total investment costs amount up to 230 millions BAM, in terms of constructing the heat water pipelines from TPP Kakanj to the areas around and of Sarajevo. The following chart represents the percentage values of constructing the highway heat water pipelines and the investment expenses of constructing the branching heat water pipelines.
The operating expenses (OPEX) consist of two main categories of: operating expenses while producing heating energy at TPP Kakanj, and operating expenses of the main and branching heat water pipelines.
Taking into account the aforementioned expected effect while realizing the project, the price of the heating energy at the exit of the highway heat water pipeline, which justified the realization of the project, amounts to 58,84 BAM/MWh.
* The average annual growth rate of the costs of 0.12%.

6. Environmental benefits
Energy benefits
The achievement of high efficiency cogeneration
Increasing security of supply thermal energy
Providing diversification of heat sources
The release of depending on a single energy source (imported gas)
Fully used local natural resources
Primary energy savings in cities
Improving the image of cities through the introduction of high-efficiency heating based technologies, with the contribution of energy efficiency at the regional and national level
Contribution to sustainable heating system in cities
Environmental benefits
Improving the environmental aspects of the local and wider level:
reducing particulate emissions
(At the level of TPP Kakanj - measures already implemented)
reduce emissions of NOx and SO2
(At the level of Kakanj - measures in the plan, from 2018 to 2027 NERP)
reduction of CO2 emissions
(Significant effects by replacing individual furnaces and existing boilers)
The main energy benefits are listed here:
Emisions

7. Conclusions Lower price of thermal energy
heat price at the point of connection to the heating network of KJKP Toplane Sarajevo, much lower than the production cost of thermal energy in KJKP Toplane Sarajevo based on imported natural gas
The possibility of optimizing cost efficiency for heating
The funds remain in the payment system of BiH
Fully used local natural resources
contribution to the development of the mines / alternative breeding fast-growing biomass
contribution to the development of the biomass market (planned projects kosagorijevanja)
Job creation and the development of skills of workers in the construction phase of hot water pipelines
Creating conditions for the construction of a high-efficiency cogeneration of Block 8 in TE Kakanj
Implementation of the project creates a framework for the development of high efficiency cogeneration in primary energy savings based on a useful heat.
The project has good financial performance for a given model of financing the realization of the project at a ratio of 20% of its own funds and 80% of loan funds by applying a discount rate of 8% → NPV 48,291, KM, payback period 9 years, and the relative flexibility in terms of analysis sensitivity.
Elektroprivreda BiH with this project creates the conditions for the country to comply the provisions of the Directive on the energy of efficiency (Directive 2012/27 / EU).

In addition to the high financial and market efficiency, the project has a high socio-economic efficiency, because with evident immeasurable positive socio-economic effects, the project would accelerate the pace of socio-economic development (possibly lower heating costs, increase employment, etc.).
