PRO and CONTRA for NRE development
§energy security, health and environment benefits, R&D and industries development (might be in different order)
§cost inefficiency without subsidies, low income in developing economies (high up-front cost), health and environment problems (long-run consequences of Genetic Engineering, competition to food production)
QUESTIONS TO ADDRESS [from phase I] How to eliminate or reduce the relatively high cost of renewable electricity technologies? What is the real cost of supplying electricity from fossil fuels? If there is any externality?
5
POLICY OPTIONS TO PROMOTE NRE
§“Let flowers blossom all” [Chairman Mao] (budget spending for R&D activity)
§Through Renewable Share Portfolio (command & control economy)
§Tax incentives and subsidies (more market oriented)
METHODOLOGY
§ analyse structure of electricity cost and assess subsidies/competitiveness of NRE toward conventional technologies
§ assess NRE share in power generation with and without external costs under fair competition among technologies

Defining EXTERNALITY “Fuel cycle externalities are the costs imposed on society and the environment that are not accounted for by the producers and consumers of energy, i.e. that are not included in the market price. They include damage to the natural and built environment, such as effects of air pollution on health, buildings, crops, forests and global warming; occupational disease and accidents; and reduced amenity from visual intrusion of plant or emissions of noise. Traditional economic assessment of fuel cycles has tended to ignore these effects.” European Commission
Optimal private and social costs for electricity demand

BASIC ASSUMPTIONS Leveraged cost of electricity production is the sum of four components : investment cost (incl. cost of financing), operation and management cost, fuel cost and externalities. Leveraged Cost [¢/kWh]= Investment Cost + O&M Cost + Fuel Cost + Externality Cost Externality costs are based on EU 2003 estimations
Subsidy assessments (lower boundary) InvestmentCost(RE) + O&Mcost(RE) + FuelCost(RE) + ExternalityCost(RE) = InvestmentCost(CT) + O&Mcost(CT) + FuelCost(CT) + ExternalityCost(CT)
InvestmentCost(RE) =
Specific_c ost(RE) × Loan_coefficient(RE) Lifetime(R E) × Capacity_factor(RE)
Specific_cost(RE) Ext =
InvestmentCost(CT)+ (O & Mcost(CT)- O & Mcost(RE))+ (FuelCost(CT) - FuelCost(RE) + (ExternalityCost(CT)- Externalit yCost(RE)) Lifetime(R E) * Capacity_factor(RE) × Loan_coefficient(RE)

Impact of externality internalisation on renewable electricity competitiveness Externality internalisation in APEC region will ELIMINATE SUBSIDIES for wind, biomass, ocean and geothermal electricity towards COAL power generation. Wind became competitive to GAS for all APEC economies, except Indonesia, Malaysia and Russia. Biomass and ocean electricity will be LESS COMPETITIVE to NUCLEAR technology. Solar (PV and thermal) technologies remains ineffective options and will require substantial subsidies.
BASIC ASSUMPTIONS AND SCOPE least-cost lp model
• • • •
Two different estimations - with and without externality accounting (Externality case and BAU case) - are compared Two time periods: 2005 to 2010 and 2011 to 2020 Total electricity demand according to APERC projections (incl. interconnections) Capacity projections based on: § official national and/or industry outlook for thermal and nuclear facilities § technical potential for NRE (allowing maximum room for expansion)

RESULTS AND FINDINGS • the real cost of generation would be twice as much as that without externalities, US$ 1,171 Billion (Generation cost + Externality cost) • economies could actually save up to 5% of real cost with the application of externality

RESULTS AND FINDINGS (2) Individual sensitivities of APEC member economies to the application of externality costs
• Internalising externalities, almost half of the APEC member economies have significant changes (more than 5% ) in generation structure toward NRE • estimations didn’t take into account the costs of transmission lines construction, and power dispatching.
RESULTS AND FINDINGS (3) Annual externality cost for top nine APEC economies in year 2020 will be 67 bln USD LESS while it need some 173 bln USD MORE NRE investments for “Externality” case in the next 15 years. Thus average pay-back term for investments is less then three years.

RESULTS AND FINDINGS (4) • Southeast Asia economies are the most to gain in the internalisation of external cost
Sensitivity Analysis • Ranking of electricity generation technologies for various externality cost a) externality cost 1/3 less; b) adopted (normal) externality cost; c) externality cost 1/3 more
13
Sensitivity Analysis (2) • Assessment of increasing investment and O&M costs for NRE due to they intermittence nature and more transmission lines requirements. The case of China lead to conclusion that technology ranking is also very stable and in favour of NRE
Sensitivity Analysis (3) • Comparison between normal and case of increasing investment (+20%) and O&M (+7%) costs for NRE. Eight instead of nine economies gained from externalities internalisation for more then 5 percent.
14
Sensitivity Analysis (4) • Comparison between normal and of increasing investment (+20%) and O&M (+7%) costs for NRE. Same nine top economies has the same externality effect of 67 bln USD. Average pay-back term is slightly more then 3 years.
Sensitivity Analysis (5) Impact of externality cost internalisation to the average growth rate of renewable electricity in the APEC region,difference of “Externality” to BAU cases
15
Implications Internalising externality cost within APEC region would: § Increase the renewable electricity share less then 3 to 4 percent of total electricity production in the APEC region (or 430 to 600 TWh). § Increase by about 3 to 4 percent the average annual growth rates of renewable electricity production in comparison to the BAU case. § Increase the average generation cost of electricity, twice that of its current level.
Implications (2) § An average of 2 to 3 yield of externality cost per renewable electricity investment cost could be expected. § Additional investments for renewable electricity will reach about US$200 billion in the next 15 years. § Externality costs based on ExternE assessments are considered to be close to optimal for the purpose of renewable electricity promotion.
