Burlingame, TCS secretary JT J 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. PMC Members April 13, 1992 Meeting Notes April 28, 1992 Page 2 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.
