With thecapacity to transmit 8,100MW, TCN successfullytransmitted the enhanced peak through the nation'sgrid at a frequency of 50.08Hz.The Ag. MD/CEO of TCN, Engr. Sule Abdulazizencouraged all sector players to work together toensure sustained improvement in the power sector.TCN he said has continued to build more substationsas well as install additional transformers in varioussubstations nationwide. It is also restringing oldtransmission lines to further increase TCN’scapacity to transmit more bulk electricity to Discosnationwide. As at date, he said, TCN is able toefficiently wheel increased generation through thenational grid.Page 3Transmission Company of Nigeria

TCN NewsletterNAPTIN PROPOSES CAPACITYBUILDING PLAN FOR TCNBy Stella EjikonyeThe Management of the NationalPower Training Institute of Nigeria,NAPTIN, has called for more synergywith TCN, in area of capacity building toenhance productivity.The Director General of NAPTIN, Mr. AhmedBolaji Nagode, made this known when he ledthe management of the company on acourtesy visit to TCN.According to him, the Agency was out toensure that industry players fully utilize thepotentials of NAPTIN in meeting their goal ofhuman capacity development. “I remembervery well that the Honorable Minister ofPower and the Honorable Minister of Statefor Power, have always enjoined us to worktogether as agencies under power, to ensurethat we collectively utilize our potentialstowards realizing the goals and objectives ofthe power sector” he said.The institute, he said, has trained about1,000 staff of TCN in various areas fortechnical and non-technical between 2019and 2020, and that reports show that thetraining positively impacted their jobs.L-R, Ag MD/CEO, TCN Engr Sule Abdulaziz and DG NAPTIN, Mr Ahmed NagodePage 4Transmission Company of Nigeria

TCN NewsletterAccording to him, feedback from TCNshowed that they really gained practicalexperience from the training and that theyalso do their jobs better. “This kind offeedback he said, is what encourages me tosay that there's always the need to buildcapacity to ensure that TCN delivers moreeffectively on its mandate”.Mr. Nagode further explained that NAPTINas a center of excellence, also trains staff ofother power utilities in the African SubRegion, including the West African PowerPool (WAPP) and assured Management oftheir readiness to tailor training schemes tofit TCN's capacity building requirement.Responding, the Ag. MD/CEO, TCN,Engineer Sule Ahmed Abdulaziz, said thevisit was strategic, as the currentmanagement was in the process ofconcluding its plan for the year 2021 whichis focused on training on specific skills set tofurther build capacity. He directed theHuman Resources Division to liaise withNAPTIN to properly streamline training forthe year.The Executive Director, Human Resourcesand Corporate Services at TCN, Barr.Justin Ishaya Dodo, in his response, saidthat TCN Management is committed toimplementing the capacity building policyof the company and assured NAPTIN ofTCN's support for structured and impactfultraining.Also speaking, the Executive Director,Independent System Operator, Engr.Mamman Lawal, stressed the need forquality training for the power sector andemphasized the need for NAPTIN to liaisewith TCN's training department in order toput in place a meaningful programme forthe company.Group photograph of participants at the meetingPage 5Transmission Company of Nigeria

ABSTRACTIn aiding the disposition of electrical power networkstowards controlling and increasing its ability to transferAC power, Flexible Alternating Current TransmissionSystems, FACTS, is generally employed. This paper showsresults of the study that assesses the application of FACTStechnologies into the expansion plans of the TransmissionCompany of Nigeria, not as an exclusive solution, but aspart of the solution. Load-flow, voltage and economicanalysis were carried out and the results obtained show themost suitable alternative to give technical and economicadvantages.BACKGROUNDThe Power sector in Nigeria was managed solely by thedefunct National Electric Power Authority, NEPA, whichmetamorphosized into the Power Holding Company ofNigeria (PHCN) in 2005. PHCN was unbundled into threecomponents; the Generation, Transmission andDistribution, premised on the Electric Power SectorReform Act, 2005.The Transmission sector has been unbundled to TCN(Transmission Company of Nigeria), and the Distributionsector to eleven (11) regional Distribution companies(DISCOs).For about three (3) decades there has been little or nosignificant increase to the available power generation inNigeria, nor a concrete reinforcement towards expansion oftransmission and distribution assets; the result, a radialfragile network and consequent frequent power outages.current through line, voltage magnitude, the phase angle,the control of flow of real and reactive power in thetransmission line system. The use of FACTS devicesdevelops the transmission capability by improving thedynamic operation stability and reliability. These FACTSdevices produce different alternatives in power systemplanning and optimization.There are different types of FACTS devices which can beused in a power transmission system depending on theapplicability. This paper presents the studies carried outusing NEPLAN to demonstrate the use and benefits ofFACTS specifically the Unified Power Flow Controller(UPFC) devices in TCN grid system.Additionally, a brief economic analysis is conducted to showthe gains of employing FACTS in the system in comparisonto installing of new transmission assets. The only existingcompensating equipments in the TCN power grid arecapacitor banks and reactors. The tool used for the analysisis the NEPLAN power system tool. The Type of FACTSconsidered in this study is the UPFC because of its overallattributes as shown in table 1.Table.1 below shows few ofthe types of FACTS devices and their characteristics.1. 1793-8198.R. Adapa, K. Madajewski, R. Jankowski, “Application ofFacts technology for Power Flow Control in the PolishPower Grid”, Power engineering society Winter Meeting,Vol.3., 2000, pp. 1733-1738INTRODUCTION: In the Nigerian power system, thereare some restrictions regarding expansion of thetransmission network due to right of way issues andprincipally, the lack of funds to undertake such projects.The natural preference for the IPPs is to site theirgeneration plants within close proximity of generationresources and proximity to transmission lines for easyevacuation. These factors work to limit Power generation tothe southern part of the country. This is evident in thesiting of the bulk of power generation in the southern partof Nigeria while only a small percentage is situated in theNorth. This is problematic in a country like Nigeria with aland mass area of about 924,000 km2 as manifested in theinability of the grid in controlling power to the north due toreactive deficiency, which invariable leads to voltage dropsand sometimes collapse in the network. The requirementfor better power transfer capability and controllability inthe system calls for not only reinforcing of transmissionassets and committing new power generation to increaseour generation capacity, but to consider technologicalalternatives such as FACTS that will optimize the alreadyexisting transmission infrastructure.The application of FACTS in the electric system provides ameans of governing the operation of transmission systems:Page 6Table 1: FACTS types and Applications [1]From the above table canbe seen the different FACTS devices and their applicability in the system.Transmission Company of Nigeria
