Energies and mediums supply for coal mines

OKD is an European hard coal player operating 4 underground mines at more than 10 sites with the objective to:

• Ensure the supply of energies and mediums for the operation of the sites for 20 years (~800 GWh electricity, ~1 000 TJ heat, 2 billion m3 compressed air, 25 mil m3 of nitrogen, 50 000 MWh of cold, all per year)
• Guarantee the quality and availability of the energies and mediums distribution
• Increase the safety of the operation of energy facilities
   

Veolia concluded a contract with OKD and bought energetic assets. The result is a 20-year commitment to energies and mediums supply. The scope of supplies falls within the scope of Veolia’s activities:

• Increase in generation efficiency through Veolia’s knowledges
• Increase in generation possibilities of facilities by replacing the cogeneration with a tri-generation plant, improving the compressor network and using waste heat for heating, building a cogeneration and using heat for heating)
• Excess capacity of compressed air generation used for nitrogen production

Customer benefits:

• Client can focus on core business
• Guarantee of savings (variable, fixed) and efficiency sharing
• Improvement in energies and mediums supply => Reduction of the number of breaks => Improvement in safety of mining activities
• Use of Veolia’s know-how to address its difficulty
• New technologies implementation (cold production, nitrogen production from the spare capacity of compressed air generation)
