The UNDP-GEF project will support the Government of Nigeria to develop a Nationally Appropriate Mitigation Action (NAMA) for the Nigerian Power Sector. The NAMA will target solar PV primarily in order to achieve a transformation in the electricity mix such that at least 20GW of Nigeria's electricity is generated from solar PV by 2030. The NAMA design will use a rigorous quantitative methodology based on UNDP's Derisking (“DREI”) methodology. The project will build upon existing national development policies and initiatives that seek to put in place public derisking instruments to support the more efficient and effective participation of the private sector in the power sector. The project will develop the NAMA architecture and enabling conditions through a combination of complementary policy and financial derisking instruments, which will be validated through the implementation of a 100 MW PV project. The project will contribute to the country's attainment of its voluntary mitigation targets in the energy sector, with expected direct emission reductions of 205,700 tonnes of CO2e during the project's lifetime and additional indirect emission reductions of between 6.79 and 9.72 million tCO2e. Being the first of its kind, the baseline project will also pave the way for catalysing more private investments so that the NAMA will generate national benefits related to green growth, energy security and job creation at scale.
