7A. FY22 Estimated Annual Surplus
IMC Meeting Minutes — December 9, 2022
Mark Ziesmer, AEA, reviewed the provided information showing the estimated FY22 surplus of
approximately $1,044,000 that will be refunded to the utilities. This is pursuant to the Alaska
Intertie Agreement whereby funds not used during a fiscal year are returned to the utilities who
contributed during that time. Mr. Ziesmer discussed that actual revenues for FY22 exceeded the
budgeted amount by $465,000. Actual expenses for FY22 were about $720,000 less than the
budgeted amount, with the unused funds primarily related to the Marker Ball Project. He noted
that the FY22 budget contained a shortage that was factored in the calculation of the estimated
surplus.
Mr. Ziesmer advised that the previous FY21 revenues were $2.81 million, and were lower in
FY22 at $2.29 million. The previous FY21 expenses were $2.6 million, and were lower in FY22
at $1.7 million. He highlighted again that the under -budgeted expenses include the Marker Ball
Project within the Maintenance of Overhead Lines and the Maintenance of Station Equipment
line items. The total refund to be distributed to each participant is calculated approximately as
follows; GVEA at $832,000, CEA at $57,000, and MEA at $155,000. Mr. Ziesmer reported that
the FY22 audit for Alaska Energy Authority is awaiting completion later this month, after which
time the refunds can be authorized and released. No material changes to the listed refund
amounts are expected. There were no questions.
7B. 2023 Proposed Meeting Dates
Jennifer Bertolini, AEA, advised that the 2023 proposed meeting dates were mirrored after last
year's meeting dates. Adjustments can be made, if needed, and no formal action is necessary.
Chair Jenkin stated that he has no concerns with the proposed schedule. There were no other
comments or concerns.
8. OLD BUSINESS - NONE
9. COMMITTEE REPORTS
9A. Budget to Actuals Report
Mr. Ziesmer discussed the Budget to Actual Expense Report for the period from July 1, 2022 to
September 30, 2022. The total revenue amount for the period was lower than budgeted due to
the less than expected usage from GVEA. He noted that the budget is annualized, and the timing
of invoices will be reflected as they are paid throughout the year. The total operating expenses
were approximately $635,000 less than budgeted. The total budget surplus was $367,000, and
will probably change as the year continues. Mr. Zeismer explained that the credit of $27,000
was from FY22 invoicing that was determined to be an overpayment. There were no questions.
9B. IOC Committee
Dan Bishop, GVEA, noted that he provided the Intertie Operating Committee (IOC) report just
prior to the meeting. Ms. Bertolini indicated that she did not receive the report. Mr. Bishop
advised that he would send the report again. He reviewed the information contained within the
report. During the previous IOC meeting, input was provided regarding David Lockard's, AEA,
comments on the Maintenance Subcommittee's Vegetation Management Plan. Once the Plan is
IMC Meeting Minutes — December 9, 2022 2
completed, the IOC will recommend the Plan to the IMC.
Mr. Bishop noted that the Systems Studies Subcommittee (SSS) activities were reported on by
John Bell, CEA, and much progress has been made on the Synchrophasor Project. Requests for
proposals were due December 2nd. Mr. Bishop has not yet reviewed the results. The SSS
described the Synchrophasor Project at the Northwest Public Power Association (NWPPA)
annual conference in Anchorage. Mr. Bishop highlighted that the Oscillation Study is ongoing.
HEA plans to update the Nikiski and Soldotna power system stabilizing tuning next year.
Updates to the PSSE dynamic model for Bradley Lake are in progress and will be completed
before the tunings are attempted. The SSS is working with the Dispatch and Operations
Subcommittees to develop the policies and procedures required to implement recommendations
of the Reserve Study. Progress is being made and was identified and discussed at the IOC
meeting.
A comment was made that beginning in 2023, the SSS will focus on the effects of high
penetration inverter -based generation and the ride -through capability of the Railbelt to
disturbances based upon a higher penetration of inverter -based generation. The unidentified
speaker requested additional information from the SSS regarding the scope of that focus and how
the project will develop. Mr. Bishop agreed.
Ms. Bertolini indicated that she just received the IOC report. She will distribute it to members
and link it to the online agenda. There were no other comments or questions.
9C. Operator's Report
Chair Jenkin requested Russell Thornton, CEA, to present the Operator's Report. Mr. Thornton
made a correction to the date of the included Operator's Report from November 9, 2022 to
December 9, 2022. He discussed that the usage on the Intertie has significantly increased
compared to the usage during this same time period in FY22. The key drivers include the
expanded utilization of GVEA and MEA, the pending spill at Bradley Lake that caused all of the
members to increase their transfers, and the additional energy sales across the Intertie.
Mr. Thornton advised that there were no reportable trips or events on the Intertie over the last
period. Non-Intertie events were listed in a table in the report. Mr. Thornton discussed that
frequency response of the system seems to be improving, with the notable exception of the
Southern Tie Trip on November 22, 2022. It was a 60 MW event and had a beta of 6.2. Mr.
Thornton explained the event and the factors contributing to the frequency response. He
discussed the dampening ratio of the events are significantly improved without substantial
sustained oscillations.
Chair Jenkin commented and expressed appreciation for the detailed report. There were no
questions.
