GIZ supported three regional organizations (ERERA, ECREEE and WAPP) within the framework of the programme “Promotion of a climate-friendly power market in the ECOWAS region (ProCEM)”. Within this framework, TTA supported GIZ with the drafting of three regional Standards for PV-based mini-grids in West Africa. These standards are mainly technical and focus on the installation and inspection procedures, as well as on inverters. Once drafted, these standards were presented at a regional workshop with Ministries of Energy, electrification agencies and standardization bodies of the ECOWAS region. The draft standards are to be sent to the regional electrotechnical committees for further revision. Eventually, the standards will be implemented by partners such as standard organizations, manufacturers associations, chambers of commerce and presidential committees on energy or power.
