The role of nuclear power in sustainable development of the Croatian power system

On the basis of electricity consumption forecast and scheduled retirements of the existing power plants, projections of the needed new generating capacities in the period 2001-2030 have been made. Since introducing non-hydro renewables in Croatia is still technically and financially constrained, only fossil-fired (coal and natural gas) and nuclear power plants, together with several hydroelectric facilities, are chosen as system expansion candidates. Depending on the natural gas limitations and the decision whether to include nuclear power in the developing options or not, two nuclear and two non-nuclear cases were analyzed. The optimal power system expansion plan for each case was found by means of dynamic optimization, on the basis of plants' annual production costs. The electricity generation mix for each case was found and corresponding emissions of SO2, NOx, particulates and CO2 to the atmosphere were calculated. It is analyzed how the hypothetical introduction of a CO2 tax would affect plant's annual costs and the capacity mix in the optimal solution.
