EN8 Total water withdrawal by source
We withdrew a total of 2,178 (2013: 2,312) million cubic metres of water, of which the majority, 2,094 (2013: 2,231) million cubic metres, was used as cooling water for condensers in thermal power plants. The temperature of the water flowing through the condensers rises slightly but the volume of water remains unchanged when it is pumped back into the water system. Power plants in Russia and Poland also use cooling towers, in which part of the water evaporates into the atmosphere. The water added to the cooling towers’ water circulation was previously reported as cooling water. Since 2013, this water is reported as part of the process water
because the volume and quality of the water change significantly in the cooling towers' water circulation. In Russia, water is used also for pumping ash from coal-fired power plants into ash ponds.
Reported water withdrawal is based on water flow measurements at power plants and heat boilers.
In hydropower production, all the water runs through turbines, so the water volume and quality remain unchanged. Hydropower production is not included in the above mentioned figures for water withdrawal.
