current power supply situation in the west african sub region
Current Power Supply Situation in the West African Sub-Region
  • Inadequate/Non Existent Transmission Interconnections in ECOWAS Member States and also between ECOWAS Member States;
  • Inadequate Generation Capacity in ECOWAS Member States resulting in Power Shortages;
  • Inability of ECOWAS Member States to raise the necessary financing to implement the projects required to alleviate the situation.
ecowas addresses the needs
ECOWAS ADDRESSES THE NEEDS
  • To address this situation of need, the Economic Community of Western African States (ECOWAS) created a new organization: the West African Power Pool (WAPP)
wapp vision
WAPP VISION
  • The vision of the West African Power Pool (WAPP) Organization is to integrate the operations of the national power systems into a unified, sustainable regional electricity market, with the ultimate goal of providing the ECOWAS Member States with stable and reliable electricity supply at affordable cost
wapp organization
WAPP ORGANIZATION
  • Formed January 2006 by decision of the Heads of State and of Government
    • Articles of Agreement approved

master plan for infrastructure development
Master Plan for Infrastructure Development

In line with WAPP Mission and Objectives,the ECOWAS Council of Ministers adopted in 1999 a Master Plan to develop electricity generation and transmission infrastructure, and to interconnect the national electrical power systems

master plan for infrastructure development1
Master Plan for Infrastructure Development

Revised in 2004, the Master Plan

  • Defines the long-term vision and implementation strategy for the regional transmission system
  • Identifies the capital costs of the regional transmission investment program over the next 17 years (2020 horizon)
  • Identifies requirements for the stability, reliability and operability of the regional systems

the way forward
THE WAY FORWARD
  • Realizing WAPP vision - the integration of the presently fragmented national power systems into a unified, sustainable regional electricity market – requires a long and complex process which cannot be fully predicted at this stage. We may, however, attempt to anticipate the series of steps which need to be taken for the creation of a regional electricity market
what is a regional electricity market
WHAT IS A “REGIONAL ELECTRICITY MARKET”
  • Today, there are cross-border exchanges of electricity without competition among sellers, or among buyers
    • A market would require some kind of competition
    • A regional market is different from a national market
  • We recommend the following definition: a regional electricity market exists, when
  • Producers are able to export energy on a competitive basis, or sell to a regional power exchange, and
  • Distribution companies and large end users are able to import energy on a competitive basis, or buy from a regional power exchange

CREATION OF WAPP ELECTRICITY MARKET MEDIUM TERM OBJECTIVE (2011)
suggested phases for medium term objective 2011
SUGGESTED PHASES FORMEDIUM TERM OBJECTIVE (2011)
  • Phase 1: Bilateral trading
  • Measurement of Net Transfer Capacity (NTC)
  • Unbundling of accounts for the regional network
  • Phase 2: Bilateral trading, with a few transit flows
  • Allocation of NTC on the basis of contract priority
  • Calculation of transmission tariffs for regional network
suggested steps for medium term objective 2011
SUGGESTED STEPS FOR MEDIUM TERM OBJECTIVE (2011)
  • WAPP member utilities should -
    • Establish clear rules on who has the right to use cross-border interconnection capacity
      • Should the importing country claim 100 percent for its own national power company, or genco-transco?
      • How much capacity is available for transit? When?
    • Separate the regional network from the national network
      • Best solution: separate ownership
      • Next best solution: separate accounts
    • Agree on who will pay a transmission tariff for use of the new 330kV and 225kV lines
      • How much capacity will be “reserved” for IPP deals?
    • Develop a standard transmission service contract

LONG TERM OBJECTIVE: TRANSITION FROM REGULATED PRICES TO WHOLESALE MARKET PRICES
suggested phases for long term objective 2020
SUGGESTED PHASES FORLONG TERM OBJECTIVE (2020)
  • Phase 3: Merging of selected zones in the regional network
    • In each zone there is a regional transmission company or the network is operated as one transmission company
  • Phase 4: Start of the regional electricity market
    • Competition among buyers and sellers
    • Each market participant gets access to the whole WAPP regional network by paying only one transmission tariff
    • Transit tariffs and export tariffs are eliminated
  • Phase 5: Start of a regional power exchange
    • Congestion management approach
long term objective transition from regulated prices to wholesale market prices1
LONG TERM OBJECTIVE: TRANSITION FROM REGULATED PRICES TO WHOLESALE MARKET PRICES
  • Given a political choice between:
    • Low electricity prices set by the government, resulting in blackouts and shortages of generating capacity
    • High electricity prices set by a well-designed market, with no blackouts and no generating capacity shortages

… many governments would opt for the 1st alternative

  • Electricity prices must not be too low, or power shortages will follow, nor too high, or social unrest will follow. Finding a balance absorbs most political attention, causing to loose sight of the longer-term objective of creating a regional electricity market which, with help from Adam Smith’s invisible hand, will automatically find the correct price levels.
