Technology Choices Smart Grid Planning Division • Although AMI technology has emerged for more than a decade, but there is no right technology that can fit for all environments. • RF, PLC or Cellular? Each has its pros and cons. • Smart Meter -> Modular comm. module has better future in the long run? • Etc. “No single technology can guarantee a project success.” 18

Technology Choices Smart Grid Planning Division Comparison of Technology Attributes Wireless Mesh PLC Cellular    Environment High density Complex buildings Remote Areas    Low cost Multiple meters per Low ‐ density areas  Economical room Proportion The Rest 10-15% 5-10% Concept Meter density is higher than Complex buildings where Remaining areas (even mesh) designed threshold, including number of units exceeds to keep 95% of connected metropolitan areas defined threshold ratio at early stage Deployment Areas

Procurement Strategy Smart Grid Planning Division • An AMI project not only involves most of players in organization but may also change the way they work • Need to cooperate with all relevant parts and work out in detail • Setting up a Proof of Concept (Live Demo.) during a procurement process • This is a good idea to ensure interoperability and system performance Technical Evaluation Review of the technical proposals (PASS/FAIL Criteria) (paper proposal evaluation) Qualified bidders shall demonstrate 2 Days Live key functionalities of their Demonstration proposed solutions. Qualified Bidders Bidders who pass both Evaluation qualifications will participate 22 e-Auction.
