“…The competitiveness is defined as ability of the portfolio to compete to the others. As competitiveness indicator is selected 3E indicator previously developed and published in the literature [18][19][20][21]. The 3E indicator comprises annual amount of fixed costs, annual amount of CO 2 emitted and annual amount of electricity generated by the referent portfolio.…”

“…As explained in [20,21] the 3E indicator is expressed in analytically form by the equation: where expression f cESi denotes annual amount of fix cost (expressed in millions euro per year) for i th electricity source, m CO2ESi -denotes annual amount of CO 2 emission (in thousand tons per year) of i th electricity source, e ESi -the electricity generation (in MWh per year) of i th source, while n -denotes the number of electricity sources comprising all steam turbine generators, gas turbine generators, wind turbine generators, hydro turbine generators and solar electricity sources.…”

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.

“…This indicator was used for evaluation of power systems technology portfolio's competitiveness regarding investments in assets, CO 2 emission and electricity generated. The corresponding results were presented in references [8,9] The intention was to include environment requirements in the field of competitiveness. As explained in [7] the 3E indicator is expressed in analytically form by the equation:…”

“…On the other hand, we can classify all CO 2 free technologies as dispatchable ones (hydro power, nuclear power and biomass fired), as non-dispatchable ones, like wind generators (WG), photovoltaic and solar thermal technologies, as well as limited dispatchable technologies that represent the combination of some of non-dispatchable technology and appropriate electricity storage technology. Previous classification, together with the technology matrix presented in [9], leads to definition of extended technology matrix, which is developed and discussed in [16]. In the concept of extended technology matrix important roll play technologies for carbon capture and storage (CCS) as well as technologies for electricity storage (ES).…”

In the paper are presented and discussed the results of a more complex research of technology portfolio competitiveness in power systems with high penetration of i-RES. Possible technology portfolios compositions are analyzed. The portfolios comprise very high participation of i-RES, as well as a certain participation of energy storage technologies, but also and other energy technologies like nuclear and fossil fueled power plants. Within the research are developed new competitiveness indicators i.e., dispatchability indicator and the technology portfolio?s assured capacity. The latter is defined on the basis of recently published Ulrich?s and Schiffer?s paper. Obtained results point out that inclusion of pumped-hydro storage plants improves portfolio?s dispatchability. However, within the researched interval up to PHS installed capacities relative to i-RES capacities of 0,3; numerical values of the dispatchability indicators are still below their values for the portfolio without i-RES. Increased participation of nuclear power plants contribute to the improvement of numerical values of the dispatchability indicators. The sensitivity analysis for the case of two times smaller cost of pumped hydro storage capacities is also performed. Hypothetical change of power system?s technology structure in sense of substitution hard coal and lignite fired power plants with wind generators or with nuclear power plants is also analyzed. The analysis points out that the substitution with nuclear power plants enables much better results regarding power system?s ability to change the power on demand than substitution with wind generators, particularly in the countries with high participation of hard coal and/or lignite in electricity generation.
