  1. 17th UPDEA congress IMPROVEMENT IN THE MANAGEMENT OF ELECTRICAL INFRASTRUCTURES FOR A BETTER PERFORMANCE of AFRICAN POWER UTILITIES By Mr. Cheikh KA (SENELEC, SENEGAL)

  2. INTRODUCTION In order to anchor the planning tool in the daily management of the power company, with an approach open to the great ideas developed in the "Smart Grid” roadmap. This permits to improve infrastructure management and to better the performance of African power companies.

  3. GENERAL OBJECTIVE With the aim of having an actual hold on physical flows on infrastructures expressed in electrical and monetary unit. For real-time operational planning in the short and medium term. Resulting in a continuous improvement in management through the direct and immediate means to justify the impact of new investments.

  4. SPECIFIC OBJECTIVES: CUSTOMERS • Modeling energy demand by drawing attention to the different uses and those who are willing to satisfy a request for deletion. • Determine the billing estimate in the year following this request, with easy interpretation by the client to sensitize and interest him/her in the policy of response to deletion request. • Therefore, redefine the sample form of subscription application for the electric service, to be designed with easiness of transmission by electronic mail (see sample).

  5. SPECIFIC OBJECTIVES: MV/LV SUBSTATIONS • Connect customers to the grid by geo-referencing the point of connection to the power grid. • Check the cable section system and consider reinforcements where necessary (sizing). • Determine the technical and commercial performance of each distribution substation. • Plan the network’s development situation for year N+x with a predefined load growth rate and a in planning criteria variation roadmap..

  6. SPECIFIC OBJECTIVES: DISTRIBUTION NETWORK • Determine investment volume and, depending on predefined funding conditions, draw up the financial depreciation table, • Determine the characteristic values ​​of its management and the profitability of the investment and its operation, by means of a rational allocation of predefined expenses: operation, personnel and taxes etc. (Profitability).

  7. MOTIVATIONS In Senelec’s 2008 management, a one (1) per cent improvement in the gross global performance was recorded; this corresponds, at the same year’s average price, to an income of FCFA 2,688,421,120.

  8. CONTEXT The concept of a smart meter capable of providing energy billing by the hour and so allow consumers to choose the best rate, but also to modulate consumption hours, thus enabling a better use of the power grid and its sources.

  9. CONTEXT Deregulation has not altered the technical foundation of power grid management; in particular, it does not significantly alter the physical flows of electricity in interconnected grids, which remain determined by the geographical location of the generation facilities and consumption areas, and by Kirchhoff's laws.

  10. SOFTWARE PLATEFORM (Architecture and data) • GIS: Geographical Information System • PIS: Production Information System • TNIS: Transmission Network Information System • DNIS: Distribution Network Information System • CIS: Commercial Information System • SREG: System for the Regulation of the Power Sector by the Regulatory Commission • SICF: Dealer’s Accounting and Financial Information System

  11. CONCLUSION Blueprint Planning Generation/Transmission focus on the medium term (5 years), imitating the most developed power markets like the New York Independent System Operator (NYISO), creating competition among all energy sources (oil, gas, coal, etc..) with ultimately potential interconnection patterns at the most competitive KW capacity cost.

  12. CONCLUSION In order to curb the recurring power generation deficits and to open the energy market, it is advisable to mention in the PIS and TNIS, the estimated and variable power generation and transmission capacity price from year n to year n+5, corresponding to: • Power generation offer in periods of low load (December-May; • additional generation offer for the period of high load (June-November); • the specific offer of generation of rapid units to get through peaks.

  13. CONCLUSION However, taking into account implementation delays, the prices displayed in year N+3 should be related to duly signed contracts for the construction of new works.

  14. CONCLUSION • The response to the deletion request, self power generation and storage should be a structured and regulated market, accessible to all sector players, allowing to smooth the demand curve at peak time but also to curb delays in new works commissioning and contingency cases. • In this perspective, the regulatory commission must display pricing grid forecasts over the next 3 years to assess the profitability of players’ investment projects.
