� WAPP Implementation strategy is based on realising:

� Coastal Transmission Backbone Subprogram (Côte d’Ivoire,

Ghana, Benin/Togo, Nigeria).

� Inter-zonal Transmission Hub Sub-program (Burkina Faso, OMVS

via Mali, Mali via Côte d’Ivoire, LSG via Côte 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)

� Côte d’Ivoire-Liberia-Sierra Leone-Guinea Power System Re-development Subprogram (Côte d’Ivoire, Liberia, Sierra Leone, Guinea).

� WAPP Strategic Generation Subprogram (Emergency Power

ICC Project

Data & Telecommunication- Main SystemData & Telecommunication- Main System

� Data Centre to process the data retrieved from the remote Control Centres.

� A data communication system based on ICCP links (Inter Control Centre Protocol TASEII or IEC.60870-6) for data exchange between ICC and remote CACs.

� A telecommunication backbone mainly based on fibre optic links to provide data and voice communication channels.

ICC Project

Telecommunication Design Telecommunication Design

The WAPP telecommunication backbone will be mainly based on fibre optic links (existing and new):

�Existing fibre optic links useful to connect ICC to CACs/NCCs and fibre optic links implemented within the frame of priority projects.

�Two redundant fibre optic link to connect ICC to Vedoko and Maria Gleta

�New OPGW and new SDH (Synchronous Digital Hierarchy) equipment and upgrade of existing SDH equipment.

�The telecommunication backbone will provide data, voice communication channels, and capacity for other services (video conferencing etc…)

WAPP Dark FibreWAPP Dark Fibre

WAPP Dark Fibre

ObjectiveObjective

The World Bank sponsored a feasibility study on the possibility of leveraging the excess fibre on the WAPP Power Transmission network to facilitate :

1.Information sharing with WAPP member utilities and other telecommunication requirements for the creation of the WAPP regional electricity market.

2. Improve regional telecommunication connectivity and infrastructure

3. Leverage donor support for electricity sector to facilitate telecom sector development.

WAPP Dark Fibre

The DemandThe Demand

� Need for WAPP to have redundant and reliable communication;

� Telecom operators’ international connectivity is currently constrained by limited bandwidth and high prices;

� Submarine cables are opening up the region to international connectivity and would require last mile connectivity;

� The telecom operators rely on microwave for backhaul and satellite for international redundancy – expensive and inadequate;

WAPP Dark Fibre

ApproachApproach

� Excess fibre exist on the WAPP transmission network;

� WAPP member utilities to organize themselves to lease excess fibers in their transmission lines to incumbent and new entrant telecom operators in the ECOWAS region;

� Low maginal cost of OPGW makes the optic fibre installation viable;

� Two regional optic fibre rings are identified for redundancy and reliability of WAPP network;

WAPP Dark FibreApproachApproach

� Western Ring : - Connects Senegal, Mali, Cote d’ivoire ( first Phase)- Gambia, Guinea Bissau, Guinea Sierra Leone, Liberia- OMVG/OMVS and additional new fibre

� Eastern Ring:- Connects Coted’ivore, Burkina Faso Ghana, - Togo, Benin and Niger and additional new fibre

�Connection to Sub-Marine Cable
