Ignalina and Didziasalis are neighbouring<br />

towns on the Northeastern part of Lithuania<br />

in the Utena region, relying upon heat supplied<br />

from biomass. The biofuel boiler installation<br />

and district heating projects are part of<br />

Sweden’s International Climate-Related Energy<br />

Program. The Ignalina project was implemented<br />

in 1999 and the Didziasalis project<br />

followed the example of it’s success in 2001.<br />

Main aims and motivations<br />

Ignalina: The regional administration wished<br />

to reduce the use of heavy fuel oil (mazout)<br />

and to start to use local fuel as biomass.<br />

Didziasalis: The district heating system was<br />

installed in the 1980’s to support the building<br />

material industry. When the industry was<br />

closed down in the early 1990’s the heating<br />

system became inefficient to heat the remaining<br />

buildings in the town due to it’s high production<br />

costs, being designed to supply a larger<br />

market than was actually needed. Following<br />

Swedish Energy Agency (STEM)’s financing<br />

of the first Ignalina project, Ignalina regional<br />

council turned to STEM for some financial<br />

support in the restructuring of the heating<br />

system in Didziasalis.<br />

Project details<br />

The Ignalina project concentrated heat production<br />

into one newly renovated, already existing<br />

boiler house and closed down two old<br />

boiler houses. Mazout, with a lower level sulphur<br />

content, will still be used but to a far<br />

lesser degree for peak load and reserve capacity<br />

instead of the previous 60% of supply.<br />

The Ignalina project includes the installation<br />

Ignalina<br />

Energy MWh/y<br />

of new pre-insulated pipeline of 300 meters<br />

to connect the existing networks as well as 30<br />

new substations in buildings and block centers.<br />

In Didzaiasalis a new more cost effective boiler<br />

house was built nearer the town. Furthermore<br />

the distribution system has been partly renovated<br />

and 43 substations installed.<br />

Overall evaluation<br />

Ignalina regional administration fulfilled the<br />

aim to reduce the use of heavy fuel oil (Mazout)<br />

and to start using local fuel as biomass to<br />

create local employment and adhere to stricter<br />

environmental rules that came into force in<br />

1999 from the Lithuanian government.<br />

Biofuel is expected to replace 2,300 tonnes of<br />

Mazout for each project. The energy saving<br />

from the pipeline and substation networks<br />

amount to 1000 MWh/y per project.<br />

Recently Ignalina town inagurated further<br />

biofuels boilers in the same boilerhouse as the<br />

first project. This means that the heat supply<br />

in the whole town and practically the whole<br />

surrounding Ignalina region is based on woodfuel.<br />

Enabling factors<br />

Both projects received financial support from<br />

STEM in the form of loans. The Didziasalis<br />

project also received 50% of costs from the<br />

Lithuanian government. Ignalina has 6 different<br />

suppliers of biomass so there is now<br />

possibility of price competition.<br />

Challenges<br />

All municipal heating plants and distribution<br />

networks were decentralized in 1997 and<br />

Didziasalis<br />

Biofuel 25,000 145,000<br />

many municipalities became shareholders in<br />

district heating companies. This caused problems<br />

as big towns and smaller communities<br />

had different requirements. Further reorganization<br />

took place and municipalities took over<br />

the direct management and responsibilities of<br />

the heating companies in their area. This can<br />

cause credit problems, as most lenders normally<br />

require a 5-6 year economic result history<br />

before providing loans. STEM was prepared<br />

to take the risk here as state guarantee<br />

was provided but this is only the case for few<br />

regions.<br />

Replication Potential<br />

The population is quite evenly spread out which<br />

is important for the implementation of biofuels<br />

projects. Therefore the conclusions of the<br />

Ignalina project will contain valid insights for<br />

Lithuania in general. Biofuel resources in the<br />

country are good and the technology is available,<br />

nearly every municipality has a District<br />

Heating system installed that could be renovated<br />

and reworked to make it more efficient<br />

and utilize biofuels.<br />

Change in perception of implementing<br />

RES projects<br />

It was easier to implement the Didziasalis<br />

project as financing was sought from the same<br />

source as for the Ignalina project.<br />

The Lithuanian authorities assert that the<br />

projects have played a role in the early introduction<br />

of RES into the country.<br />

RES Increase<br />

The savings caused by the plant from 1998<br />

to 2000 in Ignalina alone are as follows:<br />

Expenses from heat energy production<br />

in the company decreased by 26.5%<br />

Total heat energy costs per unit were<br />

decreased by 17.7%<br />

Expenses for fuel import were decreased<br />

by 93.4% due to the fact that all the<br />

biofuel is produced locally in contrast<br />

with the imported fossil fuels.<br />
