24 III. Taiwan s Electricity Market Reform: Amendment of the Electricity Act 24

25 Purpose of the Amendment(1) International Practices Generation Grid Retail Open Competition Introduce competition in generation market, to enhance operation efficiency, technology innovation, and service quality. Nature Monopoly Make sure the fare use of T&D grid, and the transparence of network information Free Choice Introduce competition in retail market, to give end user the right to choice 25

26 Purpose of the Amendment(2) One premise and three goals "multiple supplies, fair usage, and free choices" market under the premise of power supply stability. Premise Power supply stability Goals Multiple supplies and green energy first Fair usage for the electricity grid Free power purchasing choices for users 26

27 Planning of the Amendment(1) The Framework of Electricity Market (Before) Taipower Company Vertical Integrated Power Company (Public utility) Taipower Generations existing power plants (31,651MW) power plants in constructions approved power plants for construction Independent Power Producer 9 IPPs, 7,710 MW renewable energy Self use Power Generation Equipment (cogeneration, renewable energy, and others) Power Grid (Transmission & Distribution) Electricity Supply Obligation Common Users in Operation Regions (Electricity Price Regulation) (Operation regions:taiwan Penghu Kimen Martzu) 27

28 Planning of the Amendment(2) The Framework of Electricity Market (Amended) Establish of the Electricity Regulatory Authority(ERA), and 3 committees Electricity Regulatory Authority(ERA) Electricity Tariff Committee Electricity Mediation Committee Electricity Reliability Committee Generation Sector T&D Sector Retail Sector Direct supply Renewable energy generation company wheeling wholesale Renewable energy retailing company price is not regulated Existing traditional generation companies wholesale price is regulated New traditional generation companies Transmission and distribution company Utility retailing company wholesale Users (fully release the users power purchasing choices) 28

29 Planning of the Amendment(3) Amendment of the Electricity Act Green Electricity Comes First Electricity generated from renewable energy can be sold in 3 different ways: wholesale, wheeling,anddirect supply. Wheeling : transferred through transmission and distribution grids to the end user. Direct Supply : connecting directly to the users and thereby supplying power. Unbundling of Power Sector and Grid Sector Taipower company should be transformed into a holding company. The company of generation and the company of transmission, distribution, and retailing (which have the transmission and public retailing utility licenses) should be established under the holding company. Unbundling should be completed in 6~9 years after the amendment. 29

30 IV. Conclusion 30

31 Conclusion(1) Due to a lack of indigenous energy resources, Taiwan relies on imported energy resources for 97.53% of its needs in Fossil fuels play a major role in the energy supply structure, having a tendency of excessive concentration. As an isolated power system, Taiwan Power network has not yet been connected to other power systems. Taiwan face more challenges in balancing supply and demand, as well as the adoption of renewable energy. The structure of electricity generation in 2016: coal-fired 45.42%, LNG 32.41%, renewable energy 4.77%. Taiwan's current energy policy is developing clean energy and increasing the share of low carbon energy in electricity generation systems will be expected to reach renewables 20%, coal-fired 30%, and gas 50% in

32 Conclusion(2) In order to achieve the goal of 20% renewables in the structure of energy distribution in 2025, the government have made the Electricity Act amendment to promote the electricity market reform. As well, renewable energy precede increase the flexibility of renewable energy generator s choice. Opening of the renewable energy may attract more foreign investment in renewable energy sector and the establishment of renewable energy. 32
