    Macroeconomic effects of a low carbon electrification of greater Kampala Metropolitan area energy policy: A computable general equilibrium analysis
    (Energy Strategy Reviews, 2022) Kimuli, Ismail; Lubwama, Michael; Sebbit, Adam; Kirabira, John Baptist
    Greater Kampala Metropolitan Area (GKMA) is Uganda’s capital facing increasing pressures to raise electricity generation and also mitigate CO2 emissions. A low-carbon electrification of the GKMA energy policy is proposed for sustainability. But the macroeconomic effects of this policy are unknown. The study uses a multi-sector, single region, static GKMA-CGE model to address the knowledge gap in 4 scenarios. BAU is the baseline against which comparisons with Kabejja (20% CO2 abatement); Carbon-Tax ($100/ton) and Lutta scenarios (95% CO2 abatement) are made. The results indicate GDP increased by Kabejja:0.7%; Carbon-Tax:1.3%; Lutta:1.56% with respect to BAU. Equivalent variation also increased compared to BAU. Energy & CO2 intensities of GDP decreased in all scenarios. The study recommends Lutta for a sustainable 2050.

    A sustainable energy portfolio for Greater Kampala Metropolitan Area towards the mid-century
    (Heliyon, 2022) Kimuli, Ismail; Lubwama, Michael; Kirabira, John Bosco; Sebbit, Adam
    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.
