Related Meeting Events (2009-2010)

Presented to The 8th Meeting of HAPUA Working WG No.2-Transmission 3

Completion of AIMS-II* Report on Generation System Study was circulated to Member

Countries on 24 May 2010* Minor corrections were made upon member comments and

resubmitted to all members on 14 September 2010* Member countries accepted AIMS-II results and reports prepared by

PI SWG.* Submission of AIMS-II Final Results to member countries on

November 2010* AIMS-II can be used as a reference for implementation by concerned

parties. Further studies are required to be carried out as necessary.

Conclusions and Recommendations- The study indicates a saving of 788 MUSD with ASEAN

interconnection network which is based on the data dated 29 September 2009.

- It is noted that the nature of input for AIMS-II study is dynamic. The result should be referred to the date of data availability.

- The final AIMS-II report shall be composed of 4 reports, Generation System Study, Transmission System Study, Appendix and Executive Summary.
