Abstract

With steadfast economic development, the Greater Kampala Metropolitan Area (GKMA) faces increasing pressures to raise low-carbon electricity in the energy consumption by fuel type, abate CO₂ emissions, and also restructure transportation for sustainability. GKMA is Uganda's capital with rampant anthropogenic interference that causes climate change. A sustainable energy portfolio is a low-carbon scenario endowed with CO₂ emissions abatement strategies for GKMA towards 2050. Using TIMES-VEDA to address the knowledge gap, the study develops and examines a sustainable energy portfolio for GKMA. TIMES-VEDA is an engineering model generator with a bottom-up approach, paying in-depth attention to low-carbon themes while optimizing energy management systems. The analysis shows that sustainability is plausible by optimizing the total primary energy supply, electrical power production from PV-solar & hydropower technologies, and switching 90% of passengers of the road category to the Kampala metro.

Keywords: GKMA-TIMES model; Low-carbon development; Scenario planning; Sustainability.
