Assessment of Energy and Exergy Efficiencies of Power Generation Sub-Sector in Jordan

The present article is dedicated for evaluating the power generation sub-sector in terms of energetic and exergetic aspects. In this regard, energy and exergy utilization efficiencies during the period 1989-2006 are assessed based on real data obtained from main generators in Jordan. Sectoral energy and exergy analyses are conducted to study the variations of energy and exergy efficiencies for each of the studied power plant, and overall energy and exergy efficiencies for the entire sub-sector are found to be in the range of 31.95 to 35.99%. When compared with other neighbouring countries, such as Turkey and Saudi Arabia, the Jordanian power sub-sector is more efficient, but the opposite was noticed as compared with some developed countries, e.g. Norway and Malaysia, for year 2000. Such difference is inevitable due to dissimilar structure of the utility sector in these countries. It is expected that that the results of this study will be helpful in developing highly applicable and productive planning for future energy policies, especially for the power sub-sector.
