WAPP Project Implementation Strategy
WAPP Generation & Transmission Master Plan Its identified all the Generation and Transmission Projects required to develop and implement the power pool project; Provided a sequential and harmonised project implementation plan. 2
WAPP Implementation strategy based on realizing the following subprograms: Coastal Transmission Backbone Subprogram (Cote d Ivoire, Ghana, Benin/Togo, Nigeria). Inter-zonal Transmission Hub Sub-program (Burkina Faso, OMVS via Mali, Cote d Ivoire via Mali, LSG via Cote d Ivoire). North-core Transmission Sub-program (Nigeria, Niger, Burkina Faso, Benin). OMVG/OMVS Power System Development Subprogram (The Gambia, Guinea, Guinea Bissau, Mali, Senegal) Cote d Ivoire-Liberia-Sierra Leone-Guinea Power System Re-development Subprogram (Cote d Ivoire, Liberia, Sierra Leone, Guinea). 3

Project Implementation Strategy Traditional Approach New Approach 5
Traditional Approach Pre-investment Studies; Each Country through it Utility implements portion of project in its territory by soliciting for funding separately from the other(s); Carrying out procurement process separately from the other(s) using its procurement rules; Awards Contracts separately from the other(s) This Results in Too many contractors carrying out the project implementation; Poor project implementation coordination Long delivery periods; 6

Ikeja West Sakété 330 kv Transmission Line Lessons learned The preparation period was too long (about 10 years) Provision of consultancy services was divided into three contracts Financing of the project was not secured up front The decision process among the involved countries / utilities was cumbersome. WAPP was not actively involved at the time Division of the project into four lots created further delays
Upcoming Project Stages within WAPP- member states Recommendations of the Case Study WAPP should play a more active coordinating role and be responsible for securing financing up front The utilities involved should set up one Project Implementation Unit (PIU) Consultancy Services to be provided by one consulting firm The construction work to be carried out by one contractor working on output based specifications (PBP) O & M to be carried out by the same contractor
New Project Implementation Strategy The Authority of ECOWAS Heads of State and Government enacted a Supplementary Act on January 18, 2008 to provide the legal framework for the use of Special Purpose Companies within the framework of Public-Private Partnership to raise the required financing for the implementation of the project, operation and maintenance of the facility. 14
Conclusion New Project Implementation Strategy for Implementing Cross-border interconnection projects: Carry out the pre-investment studies including preparing functioning specifications for the project under supervision of the Power Pool Secretariat; Set up a Special Purpose Company under a Public- Private Partnership to manage the procurement process and supervise the project implementation; Use Performance-Based Procurement for the tendering/procurement for the project; Restructure the funding arrangements to support the new approach. 15
