The strong restrictions of greenhouse gasses emissions and the high penetration of intermittent renewable energy sources are the frame for researching more closely the contribution of nuclear power plants to competitiveness of corresponding technology portfolio for electricity generation. For the competitiveness indication 3E indicator is applied. The 3E indicator is expressed as the function of two variables that indicate the configuration of the technology portfolio i. e. participation of intermittent renewables in covering overall electricity load and participation of nuclear power plants in covering the residual electricity load. Obtained results point out that an increase of nuclear power plants participation in residual load contributes to the increase of the technology portfolio?s competitiveness, i. e. to the reduction of the 3E indicator?s numerical value. On the other hand, an increase of intermittent renewables participation in overall load in principle contributes to the decrease of the technology portfolio?s competitiveness, i. e. to the increase of the 3E indicator?s numerical value with the maximal value at the certain participation rate. The competitiveness of the technology portfolios for electricity generation in eleven European countries is also examined. The results point out that the country with highest participation of intermittent renewables in overall load domain has the less favorable competitiveness, and the lowest annual equivalent operation time of the technology portfolio. On the other hand, the country with highest participation of nuclear power plants in residual load domain has the most favorable value of 3E indicator and the highest annual equivalent operation time of its technology portfolio.

In February 2016, the Egyptian government introduced Egyptian Vision 2030. An important pillar of this vision is energy. Egyptian Vision 2030 presented renewable energy as the best solution to reduce the emission of greenhouse gases (GHGs) in the energy sector. Egypt’s electricity comes from various power plants; conventional thermal plants generate over 90% in which gas-fired generation accounts for 75% of the total output. Following the increase in natural gas (NG) projects in Egypt, NG is the dominant electricity source. Based on the pillars of the sustainable development strategy of Egypt, the county can increase dependence on renewable energies, and reduce CO2 emissions and bound electricity production from natural gas. We aim to determine future energy generation strategies from various power plant technologies depending on these three principles. To make the picture more clear and complete, we compared the environmental impacts and external costs of fossil, hydro, and nuclear power plants in Egypt. We used two computer codes: the model for energy supply strategy alternatives and their general environmental impacts (MESSAGE) and the simplified approach for estimating environmental impacts of electricity generation (SIMPACTS). The MESSAGE code modeled the energy-supply systems to determine the best energy-supply technology to meet future energy demands. SIMPACTS estimated the environmental impact and damage costs associated with electricity generation. The results indicated that nuclear power plants and gas power plants are long-term electricity supply sources. Nuclear power plants entail low total external-damage costs, in addition to low environmental impact during normal operation. We conclude that nuclear power plants are the best alternative long-term electricity-generation choice for Egypt to meet future electricity demands.
