COGENERATION
PRESENTATION TO PORTFOLIO COMMITTEE ON ENERGY
25 JULY 2013

2. DICK KRUGER DEPUTY HEAD TECHNO -ECONOMICS

3. COGENERATION GENERATE ELECTRICITY BY USING WASTE BY PRODUCTS
WASTE HEAT
MUST BE ECONOMICALLY VIABLE

4. BENEFITS OF COGENERATION
ECONOMICALLY VIABLE COGENERATION COULD
PROMOTE ECONOMIC TRANSFORMATION,
REDUCE DEPENDENCE ON ESKOM
REDUCE NEED FOR NEW GENERATION
MITIGATE GREEN HOUSE GASES EMISSION
REDUCE COST OF ELECTRICITY
ELIMINATE ENVIRONMENTAL HAZARDS

5. COGENERATION OPPORTUNITIES IN MINING INDUSTRY
UTILISATION COAL FINES FROM DISCARD DUMPS FOR ELECTRICITY GENERATION. ENABLE THE REHABILITATION OF THE DUMPS AND MITIGATE ENVIRONMENTAL HAZARDS.
USING METHANE EMISSIONS FROM MINES TO GENERATE ELECTRICITY. REDUCING THE ASSOCIATED GREEN HOUSE GAS EMISSIONS.
HEAT RECOVERY FROM METALLURGICAL PROCESSES. ENHANCING THE ENERGY EFFICIENCY OF SUCH PLANTS.

6. COGENERATION MODES UTILISING ELECTRICITY ON SITE
USING NATIONAL GRID TO TRANSMIT ELECTRICITY TO A CONTRACTED CUSTOMER
SELLING ELECTRICITY INTO GRID (IPP)

7. IMPEDIMENTS
THE CHARGES IMPOSED BY ESKOM FOR THE USE OF THE NATIONAL GRID DISCOURAGES COGENERATION INITIATIVES
SOME MUNICIPALITIES ARE NOT WILLING TO ACCEPT COGENERATED ELECTRICITY

8. RECOMMENDATION A COMPREHENSIVE NATIONAL POLICY ON
COGENERATION AIMED AT FACILITATING SUCH
PROJECTS BE FORMULATED AND ADOPTED
