Consumption of electric power in 2008 and 2009

In 2009 the power consumption of the whole concern was 95 066 MWh, whereby the biggest power consumers were VKG Oil AS and VKG Energia OÜ. Comparing to 2008 the concern consumed 88 764 MWh what is 6302 MWh less than in 2008.

In 2009 VKG Oil AS consumed 50 324 MWh power, whereas 2 711 MWh were consumed by the new oil shale processing unit petroter. 3 773 MWh from the total amount were consumed for lighting and 46 551 MWh for process units. In 2008 VKG Oil AS consumed 46 603 MWh, so 3 721 MWh more than in 2009, due to the startup of the new plant and increase of starts and shut-offs of the machinery.

VKG Energia OÜ consumed 36 000 MWh electric power in 2009. also, the company produced 78 969 MWh electric power (see the chart 3 and 4). In 2008 VKG Energia OÜ consumed 32 708 MWh electric power what is 3292 MWh less than in 2009. The increase of power consumption was determined by the startup of the sulphur recovery unit.

VKG Energia OÜ consumed 36 000 MWh  electric power in 2009. also, the company produced 78 969 MWh electric power (see the chart 3 and 4). In 2008 VKG Energia OÜ consumed 32 708 MWh electric power what is 3292 MWh less than in 2009. The increase of power consumption was determined by the startup of the sulphur recovery unit.

Other subsidiaries consumed totally in 2009 8 742 MWh. In 2008 the subsidiaries consumed 9 453 MWh what is 711 MWh more than in 2009. The reduction in power consumption resulted from decrease of production output due to VKG resins AS.

Future prospects

Future prospects are use of energy-saving technologies and reutilization of residual heat and gases as much as possible apart from electric power, also in form of heat and vapour. Decrease consumption of power supplied from outside the concern by effecting an intensive co-production.

Water consuption
Water consumption in 2008. and 2009. aastal

In 2008 there were 3107,4 thous. cubic meters of water consumed altogether, 33,8 thous. m3  thereof was the consumption of ground water and 3073,6 thous. m3 lake water. In 2009 the total water consumption was 2475,9 thous. m3 which is by 631,5 thous. m3  less than in 2008. The reduction in water consumption resulted from decrease of production output in some subsidiary companies (VKG Resins AS) what determined in its turn decrease in demand of cooling water.

Water discharge in 2008 and 2009

In 2008 the total amount of the concern’s water discharge was 2,26 mln m3 . 1,27 mln m3  hereof made house wastewater and 0,99 mln m3  process wastewater. In 2009 the total concern’s water discharge was 2,39 mln m3 1,36 mln m3  hereof was house wastewater  and 1,03 mln m3  process wastewater. Water discharge increased by 124,5 thous. m3 due to a precipitation enhancement in 2009.
