8A. Railbelt Synchro-Phasor Project
IMC Meeting Minutes — March 24, 2023 1
Chair Jenkin requested Jon Sinclair, MEA, to summarize the discussion of the Intertie Operating
Committee (IOC) regarding the synchrophaser project. Mr. Sinclair informed that the IOC
discussed the contract negotiations for the synchrophaser project. The cost/benefit analysis is
included in the report. The IOC discussed concerns related to implementation capability with
internal labor and security. He noted that MEA could not provide implementation this year. Mr.
Sinclair discussed that when the implementation occurs, the infrastructure will need to remain
online and will be considered critical. The infrastructure is not currently considered critical.
Mr. Sinclair informed that the discussion in the IOC meeting resulted in the request for continued
review of the project. Two of the four utilities are not ready for implementation. In the IOC
meeting, they considered a motion to recommend approval of the project to IMC. The motion to
recommend approval of the project to IMC failed. Mr. Sinclair stated that the IOC will continue
discussion at their next meeting to better understand the labor, security, and technical needs for
implementation and the possibility of a phased approach to implementation. The intent is to
ensure the utilities have the staff and equipment to be successful in moving forward. Additional
review is needed before the IOC brings a recommendation to the IMC.
Chair Jenkin asked if the synchrophaser project is in the budget under miscellaneous expense.
Discussion occurred that the FY23 budget lists the Proposed Synchrophaser System at $230,000.
The SSS Committee met yesterday, and CEA and MEA reported they are not ready to implement
the synchrophaser system. The proposal is to develop a phased implementation plan that would
carry the FY23 budget amount to the FY24 budget. The new proposed budgeted amount for
FY24 is $250,000. Phase One is budgeted for $100,000 and Phase Two is budgeted for
$150,000. The Proposed Synchrophaser System line item is not currently within the FY24
budget.
A member commented that review of the annual costs also needs to occur. He noted the
possibility that the annual costs could be equivalent to or higher than the implementation costs
and wanted to ensure that the benefits would equal the annual costs.
A member commented that he appreciates moving forward in a prudent manner. He believes that
linking the utilities on a unified Railbelt is the goal and efforts to achieve that should continue.
Mr. Price discussed that the SSS Committee proposed to continue the project this year. He stated
that the ongoing budget amount will be approximately $280,000 each year. The cost/benefit
analysis is subjective and includes losses from shutdowns. The ROI is promising within millions
of dollars of returns per year. Mr. Price stated that an optimistic scenario is for the four utilities
to complete connection early next year.
Chair Jenkin indicated that review would continue and a decision would be made during the
budget discussion since it is not yet within the budget. He asked Vice -Chair Laughlin to
comment from CEA's perspective. Vice -Chair Laughlin aligned with Mr. Sinclair's comments
regarding the need for a consolidated implementation plan to understand the impacts of the
existing system, integration, and how it will be supported into the future. The effort represents an
expense to the IMC and to the utilities.
IMC Meeting Minutes — March 24, 2023 2
Chair Jenkin asked if the synchrophaser project assumes that communication is active between
GVEA and other high-speed Railbelt users. Mr. Sinclair commented that his understanding is
that the existing communication infrastructure will be utilized. He has not seen any proposal for
the build -out of additional infrastructure.
Jennifer Bertolini, AEA, indicated that Russel Thornton, CEA, would like to comment. Mr.
Thornton expressed support for the project. He explained that a dedicated connection will be
necessary, but he does not believe that a significant bandwidth channel will be needed. CEA's
system is implemented over ethernet. The proposed pilot has a conservative amount of data and
data points.
The question was asked if the current communication infrastructure will support the system.
Keith Palchikoff, GVEA, responded that the communication path from the substations to the
utilities is established. The devices are communicating to each of the utilities. The project will
take the data from the utilities and send it to a secured government data center via a secured
internet connection through the utilities' existing IT infrastructure. Mr. Palchikoff commented
that the project does not envision adding Railbelt communication infrastructure. There were no
additional comments or questions.
8B. Intertie Vegetation Management Plan
Chair Jenkin requested members to comment on the Intertie Vegetation Management Plan. Mr.
Burns informed that much discussion on the plan occurred at the previous meeting and
modifications were requested. He asked for a high-level overview of the progress and the
prioritization based on the LIDAR analysis.
Mr. Sinclair directed members to page 36 of the report showing the requested delineation of the
costs associated with the seven-year plan. He discussed that the IOC made recommendations to
approve an updated vegetation plan that includes the Teeland to Douglas section and the related
costs. Mr. Sinclair explained that the costs vary in the plan because there are both five-year
clearing cycles and seven-year clearing cycles. The total clearing costs for the seven-year plan
range between approximately $450,000 to $1 million per year. Detailed cost estimates per utility
is included in the information.
Mr. Sinclair discussed that the IOC made recommendations to approve the seven-year remote
sensing costs, which includes LIDAR, ortho-photography, heat measurements, vegetation growth
rate, and danger tree assessment. The total remote sensing costs for the seven-year plan range
between approximately $600,000 to $1 million per year. The remote sensing plan will provide
for a more accurate and focused clearing schedule, including information on the rate of growth
and the location of vegetation growth. After the seven-year cycle, the remote sensing data will be
evaluated to determine a clearing plan going forward. Additionally, after the seven years,
utilization of remote sensing will decrease significantly, only to be used every three to five years,
to ensure the plan remains on track. Mr. Sinclair explained that remote sensing reduces clearing
costs by approximately 20% to 40% after the initial data is collected. The savings is due to
clearing only in locations where vegetation growth has occurred.
IMC Meeting Minutes — March 24, 2023 3
Vice -Chair Laughlin asked for additional information regarding why the clearing costs in 2024
are significantly higher than the costs each year from 2025 through 2030. Mr. Sinclair explained
that the costs in 2024 include clearing of the access paths to get to the right-of-ways. The access
path clearing is not included in the out -years.
Mr. Burns inquired if the current LIDAR data has been taken into account within this plan to
address the areas of highest priority and risk. Mr. Sinclair commented that he does not believe
the LIDAR data was taken into account in the proposed plan. He explained that the LIDAR data
provided a 3D image, but it was not focused on vegetation management. It was focused on the
structures through an engineering and technical evaluation. Mr. Sinclair indicated that the remote
sensing will focus on the vegetation specifically. The crews who were in the field provided
information, which was useful in creating the clearing cycle plan. He explained that clearing is
generally conducted on a time -based rotation.
Mr. Burns asked if the remote sensing will fly over the entire Intertie on an annual basis. Mr.
Sinclair agreed. Mr. Burns inquired as to the advantages for collecting the data every year, rather
than every other year. Mr. Sinclair explained the intent of the seven-year cycle is that each
section will be cleared and the data points will be collected annually to show the growth rate,
health of the trees, and impending danger trees for each section. He noted that the cost scenario
presented is the highest range and there is a possibility that the actual costs could be lower. After
the data is collected, the vendor will provide a report of their recommendation. Mr. Burns
suggested the consideration of conducting the remote sensing every other year. A determination
could be made later if it is best to conduct the remote sensing annually. Mr. Sinclair explained
that a certain number of data points need to be collected over time in order to compile the report.
Mr. Price requested information regarding additional benefits that the data could provide beyond
the vegetative aspects. Mr. Sinclair informed that the data will assist with inspections and
assessments of possible structural issues, including insulators and low wires. He noted that the
LIDAR provides positioning of the structures and the remote sensing would also provide the
positioning of structures.
Mr. Burns asked if the annual remote sensing replaces the current LIDAR. Mr. Sinclair informed
that there is currently a complete LIDAR model of the line. The only time the LIDAR would
need to be updated is if a structure is replaced. Mr. Sinclair does not believe that remote sensing
has the point density to be utilized for the design aspect of the line.
Mr. Burns asked if any action needs to be taken at today's meeting. Chair Jenkin asked for the
will of the Committee on how to move forward. He discussed that the intent is to approve a
formal clearing plan. He does not see any issues with the clearing cycles presented in the
proposed plan. Chair Jenkin noted that further discussion will occur while reviewing the budget
to decide how much of the technology to use, at what cost, and at what frequency. He suggested
the possibility of approving the clearing cycle and the budget, and then working over the course
of the year to answer further questions regarding the flyover, frequency, identification of the
health of the trees, and width of the identification span within or outside of the right-of-way.
IMC Meeting Minutes — March 24, 2023 4
MOTION: A motion was made by Mr. Burns to adopt the Intertie Vegetation
Management Plan, as submitted, for placement in the budget this year and to request the
IOC to evaluate best practices in assessment and effective clearing. Motion seconded by
Vice -Chair Laughlin.
Mr. Burns expressed concerns regarding the plan, but he wants to move the process forward and
include the plan in the budget this year. He shared GVEA's experience that adhering to a
clearing cycle does not make sense because growth rates are dramatically different in certain
areas. GVEA assesses the areas and realigns the clearing efforts to address the highest priority
issues first. Mr. Burns requested that the IOC evaluate best practices regarding the assessment of
the Intertie and regarding the most effective manner of clearing.
Chair Jenkin informed that MEA sees growth rates that are significantly lower in the northern
part of the system than in other parts of the system. MEA's clearing cycles vary from five to
seven years based upon the physically observed growth rates by the clearing inspectors and
arborists. He expressed support for a more scientific approach. Chair Jenkin noted that the
majority of MEA's tree outages are from outside the easement. He would like additional
information regarding the significance of the issue based upon the clearing width and the height
of the vegetation on the side. Chair Jenkin expressed support for the motion, with an
understanding that continued updates will be given and that more clarity will be provided prior to
approving the next budget cycle and the next flyover.
Mr. Burns explained that the motion does not approve the plan for seven years. It provides a
good start and a good basis. The expectation is that evaluation will continue to determine best
practices and improvements.
Vice -Chair Laughlin echoed Chair Jenkin's sentiments regarding clearing and following annual
cycles. He highlighted the surprise occurrences of danger trees falling in from outside the cleared
right-of-ways. Vice -Chair Laughlin believes there is value in taking the scientific approach in
identifying danger trees and implementing early mitigation. He is supportive of the motion and
of reviewing the approach and benefits annually within the budget.
Mr. Price asked if an overall width was identified as to how far beyond the right-of-way the
cameras can view. Mr. Sinclair noted that he will verify the actual span width and provide the
information. He explained that the usual width is a couple hundred feet on either side of the
right-of-way. Mr. Price expressed support for the budgeted amount. He discussed the importance
of ROI. The higher the cost/benefit, the easier the funding will be in the future.
Mr. Burns commented on the importance of understanding the danger trees and the magnitude of
the impact of the trees falling from outside of the right-of-way into the line. He noted that type of
information and data would be valuable for current legislation under review. Understanding what
percentage of the trees are falling from outside of the right-of-way is useful because there should
be no liability for those occurrences.
A roll call was taken, and the motion to approve the Intertie Vegetation Management Plan,
as submitted, was approved unanimously.
IMC Meeting Minutes — March 24, 2023 5
7A. FY24 IMC Budget
Mark Ziesmer, AEA, gave a high-level review of the proposed FY24 IMC Budget. Total
expenses for FY24 are $3,724,200. This is an increase of about $1.2 million from FY23. Much
of the increase can be explained within two sections of the budget. The first section is FERC 569
of $740,000 related to reinsulation of structures. The second section is FERC 571 and the
increases related to the listed maintenance, repairs, and clearing. To counter the increases, there
is a reduction under FERC 571 for equipment repair and replacement related to the completion
of the marker ball project in the summer. Mr. Ziesmer informed that there is a reduction in
administrative expenses of approximately $50,000. The Miscellaneous Transmission Expense
was less for FY24. The potential increase for the synchrophaser discussed at today's meeting is
not included in the budget.
Mr. Ziesmer emphasized that revenues are a function of expenses. One of the drivers of
calculating the revenues for FY24 is the level of operating expenses. Operating expenses have
increased; therefore, the required revenue has increased as well. He reviewed the summary of the
revenue, including usage, capacity, and admin, totaling $4,724,189. Mr. Ziesmer noted that the
amount of usage projected for FY24 is less than FY23 by approximately 180 MWH, but because
the operating expenses are higher, the total cost increases, which increases the total revenues.
The total expenses, including both operating and administrative, is $4,440,200. The planned
surplus is $283,989.
Mr. Price indicated that there was an error on the Miscellaneous Transmission Expense line item.
The total of $466,000 should be approximately $254,000. He provided supporting documents to
members that summarize the three planned studies that were requested by the IOC to the SSS
Committee. There is an additional $12,000 that should be included within the line item for SSS
travel expenses to the Lower 48 for a trip related to research on best practices. Mr. Price
explained that the $230,000 amount included for the Proposed Synchrophaser System in FY23
would move to FY24, and the total amount would be $250,000, as discussed earlier. If approved,
the new total for all line items within Miscellaneous Transmission Expense is $516,000, rather
than $466,000.
Mr. Burns commented that the FY24 budget increased approximately $1.2 million from FY23.
He asked to know the MWH rate increase that corresponds to the budget increase. Chair Jenkin
indicated that the capacity rate is 3.94. Mr. Price explained that the capacity rate and the usage
rate will remain the same because the operating expenses are not changing. The admin expenses
have increased. Chair Jenkin indicated that the rate is about 12.4 cents per MWH.
Chair Jenkin requested Dan Bishop, GVEA, provide updated cost estimates from the project
engineer. Mr. Bishop discussed the additional cost estimate details for the Cantwell switch
replacement line item under FERC 570 Maintenance of Station Equipment. The $156,000 cost
has increased to approximately $320,000.
Chair Jenkin veriAed that all of the projects within the budget have been vetted by the IOC as
necessary. Mr. Burns explained that the budget, as presented today, is for posting for public
IMC Meeting Minutes — March 24, 2023 6
comment. He noted that additional discussion will occur regarding line items related to re -
insulating the 115 kV section of line to 138 W. Mr. Jenkin gave a brief history of the issue and
he read the concluding statement by the Regulatory Commission of Alaska (RCA) indicating
there is no requirement to reinsulate. He informed that there is a Topic One application for
federal funding which includes the reconstruction of the 115 kV line to a 230 kV line. The
recommendation from the utilities is for the line to operate at 230 W. Mr. Burns suggested that a
budget amount is proposed for the cost of reconstruction of the 115 kV line to a 230 kV line,
rather than reinsulating the 115 kV section to 138 W. The SSS has been tasked to review how a
230 kV line affects transfer limits on the Intertie. The SSS will not be involved with design of
the 230 kV line. A cost estimate for the design is expected to be acquired and presented by the
next meeting.
Vice -Chair Laughlin requested additional information regarding the federal application. The
process was reviewed. The concept paper was submitted and accepted. The application phase is
underway. If the application is selected, then the negotiation process will begin. The
determination of grant funding is expected by the end of the year.
Joel Paisner, Ascent Law Partners, was requested to advise on the action that needs to be taken
today regarding the budget. Mr. Paisner recommended that the IMC consider a motion to
authorize the posting of the budget. It is not a final budget, and it is appropriate to continue the
discussions.
MOTION: A motion was made by Mr. Burns to post the budget, as submitted. Motion
seconded by Vice -Chair Laughlin.
Mr. Burns commented that he understands that this is not a final budget and additional discussion
will continue regarding the best course of action moving forward.
Mr. Paisner explained that the budget will be posted and will receive comments for 30 days. He
informed that Chair Jenkin's comments will be incorporated into the general comments and will
be addressed in the final adoption of the budget. This is the beginning of the budget process.
Chair Jenkin noted that the budget will go out for public comment, as presented. Before
finalization of the budget, the IOC will discuss the comments, including the line items of the
Cantwell breaker amount, synchrophasers funding, and reinsulation of the necessary portions of
the 138 kV line. No special meetings need to be called.
A roll call was taken, and the motion to post the budget, as submitted, was approved
unanimously.
