    Toward improving energy security in Kenya via HTLS conductors and load balancing
    (Strathmore University, 2024) Mkabane, C. C.
    The Industrial and Commercial sectors of the economy are rapidly growing and hence, energy consumption and transmission line loading are also increasing. This explains the major breakdowns related to transmission lines since the initially installed lines are not able to handle the increased energy requirements. Previous studies have been done replacing ACSR with ACCC conductors to reduce thermal line losses. The project aims to replace ACSR with ACCC conductors in short lines, analyze the length of the line in which the ACCC conductor will cease to be beneficial, and analyze the mechanical properties of the line. The Kenyan grid will be analyzed in its present state by performing a load flow analysis and a sag and tension analysis. The short lines will then be replaced by ACCC conductors and the load flow and sag and tension analysis of the new system done. The two systems will then be compared. The length of the line in which the ACCC conductor will no longer be beneficial for application will be determined. The analysis will be performed using Power Factory DigSilent software.

    Adoption of Behind-The-Meter Battery Storage Systems for residences in Kenya
    (Strathmore University, 2024) Wambugu, A. W.
    This research investigates the adoption of Behind-the-Meter Battery Energy Storage Systems (BTM BESS) in Kenyan urban households, focusing on mitigating the challenges posed by unreliable electricity supply, particularly for households engaged in work-from-home (WFH) activities. Electricity reliability challenges in Kenya's densely populated urban areas presents a significant challenge to the growing WFH workforce. While BTM BESS offer a potential solution for reliability, their affordability with grid-charging remains uncertain. The study develops a modified Levelized Cost of Storage (LCOS) model that integrates the WFH Reliability Metric and the WFH Income Value of Lost Load, offering a nuanced understanding of BTM BESS affordability tailored to the needs and economic realities of WFH individuals. Analysis reveals that BTM BESS becomes increasingly affordable as a reliability solution for WFH individuals, particularly those facing frequent outages or whose income is highly dependent on constant electricity access. This research contributes to the discourse on sustainable energy transitions by highlighting the economic and reliability advantages of BTM BESS for urban households in Kenya, proposing policy recommendations to enhance BTM BESS adoption and support the provision of reliable electricity as per Sustainable Development Goal 7 (SDG7).
