 Emissions of Gases Causing the Greenhouse Effect by Thermoelectric Power Plant in the 2000 -2020 Period 

1. Introduction 

Our objective in this work is to develop a methodology for evaluating the emission of the public thermoelectric power plants in different scenarios of economic development and the use of this form of generation considering the different usable fuels. For this purpose we will follow the following path

  • 1. Obtain the production values associated with a Reference Economic Scenario;  

  • 2. Study the evolution of the equivalent energy/GNP ratio in Brazil, study this ratio in other countries in recent time and its projection in order to determine the demand growth in equivalent energy associated with the GNP;  

  • 3. Study the evolution of electric energy participation in consumption in equivalent energy in Brazil, study this relationship in other countries in recent time and evaluation of electric energy consumption 

  • 4. Evaluation of loses, imports and the participation of self producers aiming at obtaining the energy generation demand concerning public power plants (and those of self producers); 

  • 5. Evaluation of the participation of public power plants in electricity generation;  

  • 6. Projection of thermal power plants participation in the total electric energy generation and the participation of different fuels in this generation;  

  • 7. Study concerning generation efficiency and its projection for the different fuels and consumption of these fuels in the corresponding electricity generation;.  

  • 8. Projection of thermal power plants emissions using fuel demand and information previously obtained for the 1990-1997 period; 

  • 9. Evaluation of the global capacity factor for different power plant types;  

  • 10. Evaluation of the necessity of increasing the Installed Capacity.  

Note: Steps 9 and 10 are necessary, in a strict sense, for emission calculations and were carried out to estimate the necessary generation capacity and compare it with the planned one. The preliminary results can be found at the end of the present work.
