### A LONG-TERM ENERGY PARTNERSHIP

Since 2010, Veolia has been managing facilities used to produce and supply heating, electricity and compressed air for the OKD Group, based in Ostrava. Modernizing mining facilities and ensuring the safety of miners have been a focal point of the initiatives. One of Veolia’s solutions has involved installing a tri-generation plant to supply heating, electricity and compressed air – all in line with mining requirements, which leave no room for error. Veolia also supplies cooling to provide air-conditioning for a mine shaft reaching to a depth of 1,300 meters. Cooling is generated by three turbo compressors with an output of 10 MW, which could subsequently be boosted to 13 MW. All three machines use environmentally friendly coolant.
