Primary Raw Materials<br />

Among primary raw materials for the<br />

production of electricity in 2002 coal was<br />

the most important (55%), followed by<br />

hydropower potential (45%), while natural<br />

gas and liquid fuel represent less than one<br />

percent. Premogovnik Velenje (Velenje<br />

coal-mining company) provided us with<br />

coal.<br />

Supply Optimization<br />

The achieved average total price of<br />

purchased electricity exceeded 8 SIT/<br />

kWh, which was largely due to quite<br />

unfavorable hydrologic conditions.<br />

This caused the production of lowercost<br />

hydropower in companies within<br />

HSE Group to remain 11.4 percent<br />

below the planned production level,<br />

and subsequently the higher-cost ©oπtanj<br />

coal-fired thermal power plant production<br />

had to be increased by 11.5<br />

percent. This change in the structure<br />

of purchased power could in fact<br />

cause a substantially larger increase in<br />

the overall price. This was avoided by<br />

introducing the following measures:<br />

• Purchases of additional quantities of<br />

coal at a lower price<br />

• Specific coal consumption was kept<br />

2.5 percent below the planned figures<br />

• Production levels in the most expensive<br />

gas power generators at the<br />

Brestanica thermal power plant<br />

were reduced by 65 percent<br />

By using the balance <strong>group</strong> and electricity<br />

production system we produced<br />

the appropriate market products of<br />

band, day and night power, as well as<br />

individual peak hour products that<br />

were included in the HSE corporate<br />

range of products and services from<br />

the supplied generated electricity.<br />

Coal<br />

We purchased a total of 41,093 TJ<br />

of coal from PV (Velenje coalmining<br />

company) for the requirements of the<br />

production of electricity and heat at<br />

TE© (©oπtanj thermal power plant).<br />

The energy value of coal stock at the<br />

end of 2002 amounted to 627 TJ.<br />

2.5.2 Heat<br />

In 2002 HSE also traded with heat.<br />

The planned overall production of<br />

heat at TE© (©oπtanj thermal power<br />

plant) for 2002 amounted to 375<br />

GWh, and the actual purchase figure<br />

was 374 GWh.<br />

This means that the realization level<br />

of the heating power purchase plan<br />

was at 99.7%.<br />
