2 Contents 1. Introduction to CEM and Macao 2. Power Network Master Plan 3. Advanced Technology Study 4. Smart Grid Development Roadmap 5. Case Study 6. Conclusion

3 Geographical Location of Macao 廣州 Guangzhou 珠海 Zhuhai China Beijing 灣仔 Wanzai 澳門 Macau Guangdong Macau 氹仔 Taipa 機場 Airport 澳門 Macao 香港 Hong-Kong 橫琴 Hengqin 路環 Coloane

4 Figures and Facts of Macao(2011) Area 29.7 km 2 Population 557,400 GDP per capita 65,502USD Peak Power Demand 725 MW Gross Electricity Consumption 4002 GWh Number of customer 220 k SAIDI 3.7 minutes CAIDI 15.8 minutes T & D loss 3.4%

5 Power Utility in Macao a. CEM Companhia de Electricidade de Macau A private utility with concession in transmission, distribution and retailing of electricity in Macao. b. Vision of CEM To be a regional role model and utilize advanced technologies To safely meet the needs of new customer requirements, To fulfill environmental regulations, and To provide reliable electricity.

6 Network Master Plan of Macao Situation by 2009 Voltage level - 220kV, 110kV/, 66kV, 11kV, 230V Connected with mainland China at 220kV and 110kV More than 50% electricity from mainland China Almost 100% underground cable network Remote indication and control, down to 11kV network SAIDI lower than 8 minutes since 2001 T&D loss lower than 5% Annualized growth rate more than 9% since 2001

7 Network Master Plan of Macao Outlook up to 2025 New land supply for development, ~20% or 4.5 km 2 Annualized growth rate up to 5% More dependence on mainland China Demanding better power supply reliability Better power quality due to more sensitive loads Pressure on electricity tariff Transparence on business operation Environmental pressure (land and emission)

8 Network Master Plan of Macao Strategies Medium/long term plan up to 2025 Simplifying voltage level 220kV, 110kV, 11kV, 230V Studying advanced technologies of power industry in 2010 by considering Operation and planning Customer participation Environmental concern Development advanced technology strategy To study and review feasibility and applicability of smart grid To conduct internal education and consensus building

9 Advanced Technology Study Purpose Reliability Efficiency Environment Protection & Clean Energy Power Quality & Customer Satisfaction

10 Advanced Technology Study Domain of Focus

11 Advanced Technology Study Recommended Technologies Energy Storage Inverters and power electronics Communications Enterprise asset management tools PEV charging infrastructure Advanced metering infrastructure (AMI) Cyber security technologies On-line sensors Mobile computing. It is called SMART GRID!

12 Smart Grid Development Road Map Considerations Smart Grid is a journey that will be many years in the making Personal computing was introduced 30 years ago Portable cell phones were introduced 25 years ago Public Internet was launched 20 years ago A smarter electric grid will become more interactive with our customers lives thru home, transportation and workplace The six domains should be covered.

13 Smart Grid Development Road Map Example

14 Case study - Advanced Metering Infrastructure in Macao AMI Consulting Project ( ) System and Technical Assessment Preliminary Feasibility Study Functional Requirements AMI Pilot Project ( ) AMI Pilot Project (~2000 customers) Data Collection Process Complete Feasibility Study AMI Full Deployment (after 2013)

15 Case study Unified Communication Strategy Project Domain 6 Communication network as strategic infrastructure supporting CEM future business development Medium/long term plan for sustainable development on power system communication Infrastructure Provide services to core business of power utility A foundation for Smart Grid developments Leverage overall power system performance

16 Conclusion Modernizing power network in Macao leads to development of smart grid technologies Overall strategy and roadmap should be defined before specific projects and actions. Pilot project is necessary as some technologies are not yet mature. Internal education and consensus building is helpful to obtain support.
