Operations Review – Transmission DivisionMoving forward, the TransmissionDivision is committed to be theregion’s leading transmission entityand the center of ASEAN PowerGrid. All our efforts are gearedtowards achieving these goals.Operational Summary[ Tenaga Nasional Berhad ] [ Annual Report 2008 ]The Transmission Division hadtaken initiatives to ensurethat transmission projectsare completed on time andwithin budget. These initiativesinclude improving procurementapproach and practices,project specifications and Billof Quantities (BQ) as well asensuring accurate project scopingtogether with a stringent QA/QC process.A total of forty (40) projectswere fully completed andcommissioned during the yearin review. Substation projectscontributed an additional 6,840MVA transformer capacity in thesystem. Out of these projects,eight (8) were capacitor bankinstallation that contributedto an additional 480 MVarcapacitive power into the 132 kVsystem leading to better voltageregulation and power quality.The 500 kV transmission linesthat connect the Jimah IPP CoalFired Power Station to Lenggengand Olak Lempit Substationswere completed in January2008. The Lenggeng 500/275 kVsubstation was commissioned inthe same month.In the Eastern region, theKandis 275/132 kV substationwas energised on 31 December2007. The project strengthensthe supply from the NationalGrid to the state of Kelantanand acts as a prime substationfor the development of theEastern Economic Corridor.The Division embarked on“Zero Tripping with Load Loss”initiative in early 2007 with anobjective to reduce the totalnumber of trippings with loadloss. A specific short termaction plan consisting of 25initiatives were implementedby all Regional maintenanceoffices. At the end of FinancialYear 2007/08, 10 initiatives werecompleted and helped contributein the reduction of the SystemMinutes with a 15% reduction oftransmission-initiated tripping ascompared to Financial Year 2007(Please see Graph 1).The upgrading of the NationalLoad Despatch Center (NLDC)project is in progress andscheduled for completion inearly 2009. The National Gridwill be equipped with a realtimestate-of-the-art SCADA/EMSsystem that helps facilitate inproviding a secure, safe andreliable operation.Operational ImprovementsKey Performance IndicatorsThe Transmission Divisionapplied the Balanced ScoreCardapproach in developing the KeyPerformance Indicators (KPIs).Technical performance wascaptured under the Customerand Internal Process perspectives.From the Customer perspective,the Division has achieved58
