SUBJECT: April 13, 1992 PMC Meeting Notes
The following is a synopsis of the TCS meeting held April 13, 1992:
Bradley Lake Tunnel
Dave Eberle - Alaska Energy Authority (AEA), presented a video tape
of the tunnel inspection and repair along with a video tape of the
vertical shaft inspection. Dave gave a presentation to the Technical
Coordinating SubCommittee (TCS) on the damage found and the repairs
done to those areas. AEA found that penstock #3 which was believed
to have been filled with rocks was virtually empty as was the rock
trap pond immediately prior to the penstock entrance. The damage was
considered minor by AEA, Stone and Webster Engineering Corporation
(SWEC) and the FERC Board of Directors member who reviewed the video
tape. AEA removed approximately 30-35 five gallon buckets from the
tunnel of loose concrete. The majority of the damage was where the surface concrete of the liner had been forced inward, resulting in
cracks or faults with the concrete. The deepest of these cracks
appears to have gone 3-4" deep into the 12" concrete liner. The
loose portions of the concrete were pried out of place and removed.
svc Project Status
Permits for Daves Creek Substation will be obtained by May 21, 1992.
This delay is not expected to delay completion of the total project.
Soldotna is proceeding on schedule. The SVC's are scheduled to be
operational sometime in November for testing with commercial
operation scheduled for March, 1993.
Microwave Link Status
AEA has not heard any new developments since the General Managers
sent a joint letter at the last PMC meeting in an attempt to gain
approval for the funding transfer from AEA to DIVCOM.
Exciter Tests
John Doudna - PTI (Power Technologies, Inc.), gave an explanation of
the exciter tests performed at Bradley Lake. The tests originally
indicated the Fuji exciter did not meet specification, but it was
learned the actual problem was the measuring device used by PTI
during the tests.

The Dispatcher Guidelines were approved unanimously and are included
as an action item for the PMC approval.
Expanded Bradley Lake Operating Conditions
The TCS considered expanding the operation of Bradley Lake to
essentially allow for operation at 90 MW during any load conditions. Due to concerns with overvoltages and system reliability the TCS did
not recommend the operating procedures be expanded.
The TCS unanimously adopted the following motion:
Move to recommend to the PMC that the interim operating levels
previously adopted by the PMC not be changed. This considers the outcome of additional studies on Kenai operating conditions requested by the PMC at their last meeting.
Bradley Lake Unit Trips
The committee discussed the Bradley Lake unit trips and requested AEA prepare a report to the Operating & Dispatch Committee.
