  1. Future Changes in Fuel Mix of Electricity Generation in Hong Kong and Implications By Larry Chuen-ho Chow Professor, Department of Geography Director, Hong Kong Energy Studies Centre Hong Kong Baptist University

  2. 1.Hong Kong 2009 population 7.004 million per capita GDP U.S. $29,401 -- Hong Kong does not produce any energy -- 2009 Total Primary Energy Requirements (PER): 577,073 TJ (19.690 million tce)

  3. 2. Dominant Role of Electricity in HK Energy Economy --2009 amount of coal, natural gas and oil products used for power generation: 389,030 Tj --Total amount of coal, natural gas and oil products consumed in HK: 548,780 Tj Share of power generation: 70.9% Fuel Mix of Final Energy Requirements (%)

  4. 3. Sectoral Consumption of Electricity (%)

  5. 4.Six Major Types of GHG 1. CO2 most important 2. CH4 3. NOX 4.-6. Synthetic Gases like HFC

  6. 5.GHG Emissions by Sector, 2008

  7. 6. Reduction in GHG Emissions, 2005-2020

  8. 7. Fuel Mix for Power Generation (%)

  9. 8. • Two power companies in Hong Kong CLP Hong Kong Electric • Governed by a scheme of control for 10 years up to 2018 -- permitted return based on 9.99% of net fixed assets -- 11.0% for investments in renewable energy

  10. 9. Current Prices of Electricity (cents/kwh)

  11. 10. Factors Affecting Future Electricity Tariff A.Future Price of Different Fuels --Nuclear expected to be cheaper than gas-fired power --Price of natural gas expected to rise and be volatile B.Investments in new power plants and other infrastructures --New combined cycle plants -- Transmission facilities --LNG terminal in Guangdong (and nuclear power plant ?)

  12. 11. Impacts on Energy Security A.Security of nuclear power supply i) Inability to store electricity ii) Dedicated transmission line to Hong Kong B. How much generation capacity to be maintained in Hong Kong C. Natural gas supply: No problem

  13. 12. Use of Nuclear Power in World • 2010 (Jan) 436 reactors in 30 states -- Total installed capacity: 372 000MW -- Provided 15% of world electricity • 3/4 electricity nuclear: France 1/2 electricity nuclear: Belgium, Sweden 1/3 electricity nuclear: Finland, Germany, S. Korea, Switzerland 1/4 electricity nuclear: Japan 1/5 electricity nuclear: Russia, Spain, USA

  14. 12. Use of Nuclear Power in World (cont’) • 53 reactors under construction ≈14% present installed capacity 141 reactors in planning stage ≈ 41% present installed capacity

  15. 13. Use of Nuclear Power in HK Daya Bay Plant • 2 reactors plus Conghua pumped storage plant -- total capacity 1968 MW -- started in 1994 -- produced 14 billion kwh per year, 70% supplied to HK

  16. 14. Nuclear: No Air Pollution & GHG • Use of nuclear from Daya Bayreduced emission of i) 7.5 million tons of CO2 ii) tens of thousand tons of SOx & NOx iii) hundreds of tons of particulates

  17. 15.Past GHG Emissions and Carbon Intensity, 1990-2008

  18. 16. Resurgence in Use of Nuclear Since 1990s • Concern about Global Warming • USA: New Plants began to be ordered since Three-Mile-Island Accident • U.K.: Building new plants • Germany: Decided to extend life of existing ones

  19. 17. Safety of Nuclear Power • Apart from Windscale, Three-mile-Island & Chernobyl, no serious accidents • Exceptionally stringent operational procedures & well trained staff • Each important control has a back-up system • Strong concrete structure Pressure vessel in stainless steel

  20. 18. Costs of Nuclear Power • Affected by many factors i) safety coefficient needed ii) interest costs iii) insurance costs iv) waste disposal costs v) decommissioning costs vi) price of uranium
