1 Senior Special Assistant on Transmission to the President The Future of TCN: Ensuring Professional Management of and Investment in the Transmission Network.Presented byEngr. A.S.A. BadaSenior Special Assistant on Transmission to the President
2 IntroductionThe decay in the power industry is immense and the resources needed to revamp the system are immense; the FGN cannot bear this burden aloneStakeholders are eager and willing to participate in any meaningful activity that can move the electricity power sector forward if the right investment climate is created
3 StrategiesStrategies that will ensure professional management of and invest-ment in the transmission network fall into 3 broad categories:The future of Transmission Company of Nigeria (TCN)Ensuring professional management of TCN;Investment in the transmission network.
4 Structure of TCN Design and Construction; TSPDesign and Construction;Maintenance and Field services;Power System Planning, Research and Development;Provision of unfettered access to market participants.S.O.Matching supply with demand at all times (operations planning);Maintenance of grid security and reliability;Administration of, supervision of compliance with and enforcement of provisions of the Grid Code;M.O.Approving entry to and registering market participants;Market settlement;Administration of, supervision of compliance with and enforcement of provisions of the Market Rules.
5 Structure of TCN (continued) Operationally TCN is structured into eight regions responsible for asset managementServices rendered by the S.O. And M.O. Are not for TCN alone but rather for all market participants.The TSP is mostly concerned with asset management while the S.O. And M.O. Are service providers.
6 Structure of TCN (continued) The TSP is mostly concerned with asset management while the S.O. & M.O. are service providers.Services rendered by the S.O. & M.O. are not for TCN alone but rather for all market participants.Operationally TCN is structured into 8 regions responsible for asset managementExpansion and rehabilitation programs are driven from Corporate Headquarters
7 TCN’s GoalTo improve on the quality of power it delivers to its customers, practice good corporate governance and ensure its services are accessible, reliable and affordable.Ingredients of a viable corporate entity include the following:Large asset base with robust asset management philosophy;Elements of natural monopoly;Appreciable capital base or ability to attract investment;Good corporate governance andStrategic planning.
8 Professional Management of TCN TCN has obviously not been able to achieve any of theseWhat can TCN boast of out of all these?Large asset base with poor management philosophy;Full natural monopolyIt is important there is a paradigm shift in the present strategic planning currently adopted
9 Factors external to TCN militate against attainment of set objectives. Professional Management of TCN (continued)Strategies must be developed to achieve the desired goals/objectives:Improvement in financial management;Ensure reliable and qualitative energy supply;Explore PPP opportunities;Concentrate on core functions;Operate the Grid Code (Ring fencing the activities of the three component sectors of TCN).Factors external to TCN militate against attainment of set objectives.Core functions can be performed better viz;100% availability of transmission lines and transformers other than the ones on scheduled maintenance outages (robust maintenance philosophy);N-1 contingencies (expansion planning to take care of redundancies);Availability of reactors and capacitor banks (power quality assurance);Functional and properly coordinated protection relay schemesAdequate automatic frequency load shedding scheme
10 Professional Management of TCN (continued) For TCN to be viable and attract private participation it should:Set achievable and measurable targets;Look seriously at business issues;Improve overall system performance;Cut back significantly on operating costs.
11 Investment Opportunities in TCN TCN provides the vital transmission infrastructure between the generating stations and the distribution companiesThere are currently two levels of transmission voltages in our grid: 330kV and 132kV.At the last count there are 5650 and 6687 kilometers each of 330kV and 132kV lines respectively.The entire infrastructure is essentially radial, without redundancies thus creating inherent reliability issues.

14 Challenges in the Sector Grid Reliability and StabilityThe current radial nature of the grid is in itself a very serious reliability concernVegetation ManagementIssues of proper management of vegetation along the transmission right of wayHuman Capacity DeficienciesRecruitment exercises have been embargoed for more than 10 years and there has not been a coordinated approach to training in the sector until the recent incorporation of NAPTIN.FinanceThis has always been in short supply either through budget appropriation or internal generation
15 Mitigation of Challenges and Areas Identified for Possible Private Sector Participation Transmission Network expansionDualization of critical lines to create reliefRelief for congested segments of the gridImplementation of the Super Grid concept (will cost c. $5bn; FGN cannot achieve this alone)Vegetation managementHuman capacity developmentLocal manufacture of components.
