IRENA prepared this report in close collaboration with Bruno Merven, at the Energy Research Centre, University of Cape Town, South Africa, who conducted major development work on with IRENA on the ECOWAS Renewable Energy Planning (EREP) too, provided modelling support in the development of scenarios for West Africa, and assisted with interpreting the results. The report benefited from review and consultations with the ECOWAS Centre for Renewable Energy and Energy Efficiency (ECREEE), as well as discussions at an IRENA-ECREEE workshop on energy planning on 10-12 December 2012 in Abidjan, Cote D'Ivoire. The workshop was attended by government and utility energy planning professionals from Benin, Burkina Faso, Cote D'Ivoire, Gambia, Ghana, Guinea, Guinea-Bissau, Liberia, Mali, Niger, Nigeria, Senegal, Sierra Leone, and Togo. IRENA appreciates the active contributions of the participants, which have made the resulting work more policy-relevant. IRENA also acknowledges ECREEE's careful review of an earlier version of this publication.
