SERBIA<br />
<strong>Serbia</strong> lays between 19 o and 23 o <strong>of</strong> east geographic length and<br />
41 o to 45 o <strong>of</strong> north geographic width.<br />
The climate is cont<strong>in</strong>ental moderate.<br />
Population 7,5 million.<br />
Capital, Belgrade with 2<br />
million <strong>in</strong>habitancies is<br />
situated on 132 m altitude<br />
and has an average temp.<br />
<strong>of</strong> 11,9 o C and rel. hum. <strong>of</strong> 71%.<br />
Due to moderate climate<br />
<strong>in</strong>dividual heat<strong>in</strong>g <strong>in</strong> small<br />
places and parts <strong>of</strong> big cities<br />
is present, while DH is<br />
presented <strong>in</strong> bigger towns.<br />

Priority <strong>in</strong> DH sector<br />
<strong>Rehabilitation</strong> <strong>of</strong> exist<strong>in</strong>g heat sources:<br />
<br />
<br />
<br />
<br />
Increas<strong>in</strong>g energy efficiency<br />
Emissions reduction<br />
Decreas<strong>in</strong>g heat losses<br />
Modernisation <strong>of</strong> network and substations (heat<br />
meters, thermostatic valves, heat coast alocators)<br />
Rational use <strong>of</strong> fuels, <strong>in</strong>creas<strong>in</strong>g <strong>of</strong> NG use<br />
Increas<strong>in</strong>g use <strong>of</strong> biomass fuels and <strong>in</strong>troduction <strong>of</strong> new<br />
technologies, more efficient and more environmental<br />
friendly
Investment <strong>in</strong> DH rehabilitation<br />
First donation was from Danish government at the end<br />
<strong>of</strong> year 2000. – 1.1 mil DEM <strong>in</strong> spare parts<br />
From 2001. – GRANTS AND LOANS<br />
The biggest implemented project - KfW<br />
Grant is <strong>in</strong> total 17.7 Mil € for rehabilitation <strong>of</strong> DH <strong>in</strong><br />
Beograd, Novi Sad and Nis<br />
Modernization <strong>of</strong> heat production process<br />
Replacement <strong>of</strong> out-<strong>of</strong>-age pipel<strong>in</strong>es<br />
Reconstruction and replacement <strong>of</strong> substations<br />
Education <strong>of</strong> staff<br />
Pilot-projects as a demonstration for a new tariff system

<br />
<br />
In last 30 years “Beogradske elektrane” shut down<br />
1000 local boiler stations – runn<strong>in</strong>g on coal and<br />
HFO<br />
Exist<strong>in</strong>g customers are connected to large heat<br />
sources<br />
This is a great contribution to Belgrade Clean air<br />
Due to technical reasons – it is not possible to shut<br />
down all<br />
We have to f<strong>in</strong>d best solution for them, acceptable<br />
from economical and environmental side
Today - Priority for LA and DHC<br />
Introduc<strong>in</strong>g <strong>of</strong> measur<strong>in</strong>g <strong>of</strong> energy and new tariff<br />
system<br />
Obstacles – energy consumption <strong>in</strong> build<strong>in</strong>g<br />
80-220kWh/m 2 y<br />
Build<strong>in</strong>g certification – sav<strong>in</strong>g energy <strong>in</strong> build<strong>in</strong>g<br />
plan for future<br />
Action plan for next 10 years
Pilot PROJECT<br />
Install<strong>in</strong>g <strong>of</strong> the Heat Cost Allocators and<br />
thermostatic radiator valves<br />
Results:<br />
- Reduction <strong>in</strong> delivered energy 15%<br />
- Reduction <strong>in</strong> electrical energy 40% (variable flow pumps)
Needs for <strong>in</strong>vestment<br />
It is obvious that thru all exist<strong>in</strong>g project was<br />
covered only 10 cities<br />
Our estimation is that this 10 towns need<br />
around 50 mil € for f<strong>in</strong>alization <strong>of</strong><br />
rehabilitation and modernization <strong>of</strong> DH<br />
systems<br />
Other 45 towns need at least 150 mil € <strong>in</strong> next<br />
10 years for rehabilitation <strong>of</strong> DH systems<br />
Such big amount <strong>of</strong> funds can not be provided<br />
by the IFI`s, but PPP will be necessary<br />
approaches for co-f<strong>in</strong>anc<strong>in</strong>g <strong>in</strong> DH rehabilitation
