3 Sequence Energy security Overview of energy sector Economics of nuclear power generation Reference to contemporary studies 3

4 Energy Security World Bank definition: the sustainable production and use of energy at reasonable costs to ensure a certain quality of life. Energy security comprises of :- Availability: Conventional and non-conventional fuels and renewable resources Accessibility: Overcome the geopolitical, financial and human constraints and major infrastructure and technology deployment Acceptability: Environmental and safety concerns Affordability: Consumers able to afford energy services 4

5 Overview of Energy Sector Production >23000 MW Summer peak demand: MW Lopsided energy mix Over reliance on thermal resources, using expensive fuels Galvanizing renewable pug-ins (wind, solar etc): Easier said than done! Generation cost higher than recoverable revenue 5

6 Electricity Generation by fuel: % 0.1 % 29 % 35.2 % Oil Hdroelectricity Natural Gas Nuclear Coal 29.9 % 6

7 Circular Debt: Rs bn (end 2012): 4% of GDP Tariff Diff. Claims vs Disbursed Subsidies Non Collection Private Governments Tariff determination- Notification Delay NEPRA : Actual vs Allowed T&D losses KESC Non collections to CPPA Fuel Price Adjustments (Rs, billion) Year Debt, Beginning of the Year

16 Cost of Nuclear power Economics of new nuclear power plants is a controversial subject High capital costs, but low direct fuel costs Comparison with other power generation methods is dependent on assumptions about construction timescales and capital financing Mitigation of global warming favours the economics of nuclear power 16

17 Cost of Nuclear power Enormous upfront cost Returns may be very great, they're also very slow It can take decades to recoup initial costs Discount rate most sensitive parameter to overall cost Once capital investment costs are effectively sunk, plants are virtually cash machines. 17

18 Cost of Nuclear power Nuclear power is cost competitive with other forms of electricity generation, except where there is direct access to low-cost fossil fuels Economics of nuclear power must also take into account who bears the risks of future uncertainties 18

19 Cost of Nuclear power There are two ways of measuring the cost of a nuclear power plant: the overnight cost, which counts up the material and labour that goes into a new plant as if it had all been purchased simultaneously, and the levellized cost, which is a measure of the total amount of energy a plant provides over its life divided by the total expenditure One is the cost of the capacity to produce electricity, other is the cost of the electricity produced 19
