Share this article

The Renewable Energy Performance Platform (REPP) is bringing together leading experts to discuss private sector mobilisation for clean energy projects in Africa in a series of side events at the COP22 in Marrakesh.

The REPP aims to mobilise private sector development activity and investment in small and medium scale renewable energy projects in sub-Saharan Africa. The REPP was developed by UNEP and EIB, and it is funded by the UK government and co-managed by GreenStream and Camco Clean Energy.

Join us in exploring opportunities for powering Africa’s clean energy transition.
