Quantifying Greenhouse Gas Mitigation Levers In Niger’s Gorou-Banda Power Plant

Abstract

This study presents the first comprehensive carbon assessment in the Gorou Banda thermal power plant in Niger. The study applies the ADEME carbon accounting method to scopes 1, 2, and 3 as defined by the reference standard for emissions, ISO 14064. The results show an average emission factor of 0.75 kgCO2/kWh due to the combustion of diesel and heavy fuel oil at around 80%. The proposed mitigation scenario, which includes the installation of 30 MW of solar PV, a battery storage system, turbine modernization, regular preventive maintenance, and intelligent load management, would enable a reduction in emissions of 17% and 45%, respectively, in the first and second years of its implementation, compared to the reference scenario, where emissions would continue to grow at an average rate of 7% each year. The results obtained made it possible to develop practical guides for emission reduction and to define a trajectory enabling the power plant to achieve low-carbon goals. The conclusions highlight the need for social, institutional, and financial support in order to accelerate the transition to a lower-carbon electricity mix in Niger and other developing African countries.
