SUBJECT: IOC November 10, 1993 Meeting
At the next regularly scheduled meeting November 10, 1993 9:30 A.M.
at Chugach Electric, IOC participants should be prepared to take
action on the following.
Stevens Substation:
* Essential monitoring requirements at Stevens.
(Interim and Permanent)
* Remote control of the high voltage devices.
* Phasing and energization of Stevens from the high side.
This may include serving load if all participant concerns
have been addressed.
Controller Duties:
* Everyone is fully aware of this issue and have been
informed as to the extent of possible changes. FMUS's
correspondence was distributed in a timely fashion giving
everyone a fair chance to prepare for this meeting. (See
attached).
Metering Procedures at Douglas
* An on-going problem has persisted with metering and
interchange accounting procedures at Douglas. Ona daily
basis, the calculated values of intertie usage do not

reflect the metered values of usage. The lack of a
prudent utility practice at this metering point results
in general confusion, inaccurate intertie usage reports
and potentially under-collection of revenue for intertie
usage.
Additionally, metering and accounting procedures require
change to incorporate AEG&T's Tap at MEA's Stevens
Substation. If any participant believes the current
procedures can accurately reflect the Stevens usage of
the Intertie, please be prepared to substantiate, in
detail, this position.
New Assignments
* At the last PMC meeting, the general managers requested
the IOC prepare a Railbelt operational issues paper. The
request was based on Ron Saxton's compendium of issues
submitted to the PMC. Ron's work established
jurisdiction for resolution and some details of the
problems. In addition to Ron's work, however, the
general managers decided it would be of benefit if the
IOC provided further insight as to the nature of the
problem and provide pros and cons to recommendations if
appropriate. Each participant should review Ron's work,
add to the list if necessary and formulate their
priorities and positions on each of the issues.
As a first cut at this assignment, I suggest we formulate
a two dimensional weighting to each of the issues (0 to
10). One axis would be participant priority (do I need
this problem solved?) and the second would be impact to
system operations (see attached for example). After we
have established ranking of issues, details and
recommendations can be provided to the general managers.
It is expected some issues are contentious and therefore
we should allow for more than one solution.
This process will provide visible representation on every
issue for each participant, develop overall priorities,
and allow for more than one solution. Feel free to call
me if you have a better idea (451-5655).

As most of you are aware, Ron Saxton has been delegated
as the "point" person for negotiating changes with
AEA/AIDEA on the existing contract. Ron needs a plan of
action from the Alaska Intertie Agreement utility
participants. Ron will meet with us on November 10, 1993
at the conclusion of our regularly scheduled meeting.
Please have your thoughts in order to make efficient use
of Ron's time.

overall operating costs of the line. The subcommittee met in Anchorage on September
this end. Both the Intertie Agreement and NERC Guides were checked for duty
requirements. It was determined that many of the presently done and charged duties are routinely
done by any interconnected utility without compensation.
The following descriptions itemize common interconnected utility tasks:
1 Intertie Scheduling - This involves coordination with all affected utilities for reserves and
energy to insure proper intertie loading. This also includes var scheduling as required to
maintain adequate voltage levels. (Since intertie overloading critically affects GVE, foA
facilities, they as a waility check this no matter who would officially “control".) LO
ails Gy EA
Actual Intertie Operation - Scheduling outages for maintenance, restoration of intertie after
forced outage, normal operation of intertie equipment. (Task for GVEA as a utility
directly affected by maintenance, used to distant Operation of system, includi: ding tag-out
clearances, and vested interest in restoration.) 1 OC. edward GUE
Time error correction - Coordination between all generating facilities to adjust time error
as required. (Task for each utility respectively.)
Operate the Interti ipment - in accordance with the Intertie Agreement each
substation would be operated by interconnected utility with their other equipment. (Kenai
SVC now not billed by CEA, Teeland SVC & 1 breaker would be operated by CEA for
free, Douglas could be operated for free by CEA or by "Controller" at no cost to Intertie.)
Perform All Loss Calculations - required for intertie schedules. (GVEA is required to do
this as a wheeling utility, not as the controller.)
Monitor and Coordinate - the power flows over the intertie within the capability of the
intertie. (It is the responsibility of GVEA and CEA to monitor the power flow of the tie
lines leaving and entering their systems as part of interconnected utilities, not as a duty
of the controller.)

7. Hourly Transaction Maintenance - records accurately all Intertie transactions, operations,
and activities involving the Intertie. Publish and distribute records showin; the daily
summary of all hourly transactions to all participants at weekly intervals. (Since this must
be performed anyway by the wheeling utiiity, they should not be a cost item.)
The following items should be done by a “Controller":
A. AUDITING - is to be done by the Controller or the State as specified. (On rotating basis
on a frequency requested by the IOC.)
B. RESERVE REQUIREMENTS - monitoring for all participants, both spinning and
operating reserve with records of actual vs required, preparing monthly report to the IOC
for review and action as necessary. (Since utilities are doing this anyway, the controller
task would be to spot check two to three times daily. Stipulated by IOC would be
whether a tep-cf-hour or integration of ten minute demands/generation system is used.
The Controller would be rotated at yearly intervals.)
C OUTAGE RECORD MAINTENANCE - on a quarterly basis published to Participants.
Keep up a database of why Intertie had an outage and problems of restoration. (On a
rotating basis.)
Discussion proceeded that these new task items should cost a small fraction of today's cost, but
that the assigned Controllers be requested to present, similar to past Intertie Budget submittals
showing hourly and yearly time by itemized subtask, their costs for Budget amendment. It was
further suggested that the State could reduce its oversight costs tremendously with similar transfer
of existing duplicating tasks to respective utilities.
We also discussed the State (AIDEA) involvement in the Intertie. This is not a recommendation
but rather a report of the subcommittee members on this issue. It is my feeling that I am
expressing Chugach Electric Association, Matanuska Electric Association, and Fairbanks
Municipal Utilities System intention that as far as we know it will be beneficial to all the Utilities
if the State will keep ownership of the Intertie, with other issues being resolved privately such
as: secretarial duties, budget preparation, maintenance, enyineering, and accounting. All these
tasks should be privately handled by the Utilities. As previously stated, this is reported only as
discussion and not as recommendation.
