IOC Report
June 21, 2024
1. Intertie Operating Committee
a. The IMC request an update on the clearing along the Alaska Intertie because limited
funds have been utilized to date. MEA has a contract that was executed in May to clear
approximately seven miles of line for approximately $380k. At this time there is no
additional clearing planned on the line in fiscal year 2024.
b. In February GVEA submitted two grant applications on behalf of the IMC, one for
Synchorphasors and one for the Alaska Intertie Snow Load Remediation. Both of those
grants have been approved, however the official award and the ability to spend on the
grants is still pending with DOE. Timing of the award is unknown but expected
sometime later this year. Upon official award, expenses can be charged to the projects
and both projects can kick off in earnest.
c. An updated draft primary frequency response policy was not available for review at the
IOC meeting. However, the draft should be ready for the next IOC meeting and then
moved to the IMC for review.
d. The IOC reviewed and approved, with comments, posting a draft RFP for an IBR study.
The SSS is managing this RFP and expects to have it posted in July. Funding for this
study is included in the proposed 2025 IMC budget.
e. The IOC discussed using the SSS to manage RRC studies. After discussion, it was
recommended that the SSS advise the RRC on studies but that the SSS does not manage
studies for the RRC.
f. There have been ongoing issues with the SVC at Healy and these issues were discussed
at the IOC. Specifically, thyristor failures have occurred, and faults have occurred due to
what is believed to be inadequate filtering of harmonics. GE, the OEM for the SVC, has
requested, and the IOC approved of, an additional $40k above the current budget for GE
to continue working on the issue. In addition, AEA is planning to set up additional
meetings with the utilities to discuss the Healy SVC.
2. System Studies Subcommittee
a. An RFP has been awarded to EPS by the SSS to look at what the system impacts would
be if the Alaska Intertie was upgraded to 230 KV. The study will look at capacity,
stability, regulation, and other key factors that may be impacted by the upgrade. Study
work is anticipated to be completed by the first quarter of 2025. This work has been
included in the IMC’s proposed 2025 budget.
3. SCADA and Telecommunications
a. Communication between Douglas and Healy has been established to allow for a
future POTT scheme to be installed. In addition, right-of-way is ongoing for the
communication upgrades between Anchorage and Douglas. It is anticipated that
a preliminary right-of-entry (ROE) agreement will be reached by July at Douglas
to allow design and construction at that site to move forward.
