ADJOURNMENT City of Seward, Alaska Council Special Meeting Agenda September 13, 2021 Page I O Powering the Future: A Rebuild of Seward's Electric System "Backbone" Seward Electric Department September 13,,�Q�1,��\\\ Where We Are • Seward owns approximately 50 miles of transmission line and three substations: Fort Raymond, Lawing and Spring Creek • All substations need refurbishing to some extent and most substation transformers must be replaced • Much of the transmission system delivery equipment and materials —poles, pole -top and support assemblies, lines, insulators, etc. —must be replaced • Voltage capacity into the City must also be increased if we are to successfully serve future load driven by shore power for cruise ships Seward must begin addressing the electric infrastructure issues it's facing before the system fails. The Projects • Nash Road Rebuild • Seward Highway Transmission Upgrade • Substation Voltage Conversions • Spring Creek Substation Refurbishment • New Harbor Substation Based on the poor condition of the existing infrastructure, the City must complete all projects to ensure system reliability and meet future load growth. Nash Road Project o Looking at a nearly complete rebuild of the delivery system: poles, lines, pole -top and support assemblies and related hardware o Most existing poles installed in the 1950s and `60s and are long past their service life o Voltage capacity of the delivery system must also be upgraded from the current 69kV to 115kV o New construction and taller poles also will allow for distribution under build, eliminating the need for separate distribution poles o Project Estimate: $3,410,955 A CEA engineer said recently that many poles along Nash are being held up by the tension of the lines. Seward Highway Project o Lowest cost project o A fairly straightforward rebuild over the last half mile of the delivery system from Dieckgraff Road into the Fort Raymond Substation o Project will upgrade this last remaining half -mile section from its current 69kV to 115kV o Good news: most of the existing delivery system from the Lawing Substation near Moose Pass into Seward is already constructed/insulated to 115kV capacity o Project Estimate: $426,184 Fort Raymond Substation Without the completion of the Seward Hwy Project, an increase in voltage to the harbor area cannot be done. Substation Voltage Conversions o Most expensive project o Lawing Substation — Includes replacing the existing failing circuit switcher, removing two transformers, installing a new transformer, and adding relay protectors and SCADA o Fort Raymond Substation — Nearly a rebuild of all substation equipment. Includes replacing two transformers from 69kV to 115kV, replacing all circuit switchers and breakers, replacing the existing ground grid, and adding relay protectors and SCADA o Spring Creek Substation — Replace existing 69kV circuit switcher with a 115kV circuit switcher o Primrose & Victor Creek Transformers — Replace existing 69kV-24.9kV transformers in each area with 115kV-24.5 transformers o Project Estimate: $5,581,873 Spring Creek Substation Refurbishment o Nearly a complete refurbishing of the entire Substation o Rebuild failing Load Tap Changer that controls voltages, replace antique relay protectors, replace fence and ground grid, replace oil -filled breakers and remove vegetation o Refurbish the 25MVA 69X1 1 5kV-1 2.5kV transformer from the Lawing Substation and move to Spring Creek Substation, add 115kV circuit switcher, oil containment, ground grid and reclosers o Project Estimate: $3,498,655 Spring Creek &.�bstatien New Harbor Substation o Build a new, small substation in the harbor area with a 12MVA, 115kV-12.5kV transformer to provide shore power to cruise ships o Electric load for cruise ships typically runs between 7 to 11 megawatts, nearly doubling the City's load on a typical summer day o Must also extend the 115kV overhead line from Fort Raymond to the new Harbor Substation o Also needed for the substation will be new circuit switchers, breakers, reclosers and other related equipment/materials o Project Estimate: $2,804,077 Seward Boat Harbor Summary o Seward has reached a point where it must begin addressing its electric transmission infrastructure, otherwise it will begin experiencing extended and costly outages o Five key projects have been identified that must be completed to improve service reliability and meet future load growth o The Nash Road Project is nearly a complete rebuild of the transmission delivery system and the Substation Voltage Conversions Project is necessary to meet future load growth o Without a new Harbor Substation, the City will not be able to reliably provide shore power to cruise ships Cost of Projects (5): $15,021,744 Cost of Transformers (7): $4.360.000 Total Infrastructure Cost: $19,381,744 Questions September 2021 October 2021 September 2021 SuMo TuWe Th Fr Th Sa SuMo TuWe Th Fr Sa 1 2 3 4 1 2 5 6 7 8 91011 3 4 5 6 7 8 9 12 13 14 15 16 17 18 10 11 12 13 14 15 16 19 20 21 22 23 24 25 17 18 19 20 21 2223 26 27 28 29 30 24 25 26 27 28 29 30 31 SUNDAY MONDAY TUESDAY WEDNESDAY THURSDAY FRIDAY SATURDAY Aug 29 30 31 Sep 1 2 3 4 12:00pm PACAB Mtg 5 6 7 8 9 10 11 HOLIDAY 7:00pm P&Z Mtg IN 6:15pm HPC (Regular Work Session Meeting) (Council L..ha....m......b..e...rs_a...................... _._._._.. 7:00pm HPC Regular Meeting (Council .ham r 12 13 14 15 16 17 18 12:OOpm PACAB :OOpm CC Special (7:00pm Work Session Meetin (Review the Seward Marine CC Mtg ncil Industrial m r Center (SMIC) Development Plan) 19 20 21 22 23 24 25 6:00pm P&Z Work Session (Ground Truthing and Land Use Table Process).... 26 27 28 29 30 Oct 1 2 5:30pm CC WS - Kick -Off Budget W 7:00pm CC Mtg Chambers Council Calendar 1 9/8/2021 11:51 AM October 2021 November 2021 October 2021 SuMo TuWe Th Fr Sa SuMo TuWe Th Fr Sa 1 2 1 2 3 4 5 6 3 4 5 6 7 8 9 7 8 9 10 11 12 13 10 11 12 13 14 15 16 14 15 16 17 18 19 20 17 18 19 20 21 22 23 21 22 23 24 25 26 27 24 25 26 27 28 29 30 28 29 30 31 SUNDAY MONDAY TUESDAY WEDNESDAY THURSDAY FRIDAY SATURDAY Sep 26 27 28 29 30 Oct 1 2 3 4 5 6 7 8 9 ELECTION DA� 12:OOpm PACAB 1:00pm Canvass 7:00pm P&Z Mtg Mt Board _.—_._:_:_._._._:- 6:00pm (Regular 6:00pm Meeting TENTATIVE TENTATIVE Budget Work Budget Work Session Session 10 11 12 13 14 15 16 7:00pm CC Mtg 6:00pm 6:00pm (Council TENTATIVE TENTATIVE umbers) ....................
