7. NEW BUSINESS
7A. Operators Report
AIMC Draft Meeting Minutes -Sept 27, 2019 Page 1 of 3
Jeff Warner, ML&P, reviewed the brief Operators Report. The flows have been down in the
third calendar quarter through August, primarily due to GVEA's reduction. He believes this
is a result of Bradley Lake and the availability of the economy energy sales. The reportable
disturbances were shown. There have been no trips on the intertie in 2019, besides the one
manual trip for the purposes of the oscillation study. The SVCs are working well.
Mr. Borgeson inquired if MEA has reduced their usage recently, along with GVEA. Mr.
Warner believes MEA has maintained fairly steady usage. He does not have the specific
information with him. MEA usage has declined a small amount in the third calendar quarter
through August.
713. Oscillation Study Update
Chair Henderson requested Russell Thornton, CEA and Chair of System Studies
Subcommittee (SSS), to provide the Oscillation Study update. Mr. Thornton apologized he is
unable to retrieve the slides prepared for his presentation due to connectivity issues. Mr.
Thornton reviewed the Oscillation Study was commissioned in February of 2019. The
scope of the study was determined and solicitations were sought from respondents PTI and
ABB to conduct the study. PTI was selected as the contractor in April. Contract negotiations
last for about six weeks and work began in early summer.
Mr. Thornton gave a detailed explanation of the modeling process. The first tasks of the
study were to identify benchmarking cases to prove the model would accurately reflect the
oscillations occurring on the Railbelt system from Fairbanks to Homer. HEA is participating
and Seward is not participating. To -date, there have been no good correlations between the
benchmarking cases and the system recordings. Work is ongoing to resolve the differences
and inconsistencies. Once the benchmarking is complete, the small signal analysis work
begins. The goal is to identify the modes and frequencies of the oscillation, as well as which
components are participating in the oscillation. Phase II of the study will include retuning
the devices across the Railbelt that have been recognized as in error, and identifying what
changes should be made to the power system stabilizers across the system. Phase III of the
study, if needed, would determine what additional equipment is required and where it
should be placed to achieve the dampening ratio.
Mr. Hickey requested additional information regarding the schedule of the study. Mr.
Thornton believes the schedule has been delayed approximately a month due to differences
in correlation. Phase I is anticipated to be completed this year. Phase II is expected to begin
in early 2020. Mr. Thornton has requested a forward look estimate from the contractor as
to any changes to the budget because of the delay. The study is under budget at this time.
8. COMMITTEE REPORTS
8A. OC Report
Chair Henderson introduced Ed Jenkin, MEA and Chair of IOC, to review the IOC Report. Mr.
Jenkin provided a written IOC Report to members. He noted HEA is an active participant in
the System Studies Subcommittee. They are fully involved in both the cost of the studies
and as a voting member of the subcommittee. Mr. Jenkin advised there are two items not
reflected in his report that will be brought before the Committee at the next meeting. The

first item regards the open access language legal review previously requested by the
Committee. The second item regards modifications to the Intertie Agreement suggested by
the Dispatch Committee that reflect updated boundaries for maintenance and operation.
8B. Budget Report
Chair Henderson welcomed Beazit Redzepi, AEA, to present the Budget Report. Mr. Redzepi
discussed the budget to actual status report concluded with a surplus. The usage report
ended the year fairly close to what was budgeted. The Alaska Intertie Trust Fund has an
ending balance of $20,762.78. This is used to pay for any expenses related to the static var
system.
Mr. Borgeson requested additional information regarding the process for disbursement of
the surplus. Mr. Redzepi explained AEA's audit will be concluded in November and the
refund will be distributed afterwards.
9. COMMITTEE ASSIGNMENTS
