These power outages worsen during the dry season making it difficult to accommodate the existing demand of electricity. The best solution to ensure reliability of the hydropower system is to incorporate reservoir storage. This study aimed at designing a reservoir based hydropower system to ensure reliability and maximum generation of power at a low cost. The system was designed to export all the energy to national grid for distribution. The monthly average design flow was 29.129 m<sup>3</sup>/s. Reservoir storage capacity of 536.998 Mm<sup>3</sup> was estimated using mass flow curve in MS-Excel while potential head of 100 m was deduced using Google Earth. RETScreen software was used to calculate hydropower potential and determine financial viability of the project. The results showed that the hydropower potential was 22.70 MW and the initial capital cost was $79,434,044 with payback period of 4.8 years. This paper’s levelised cost of energy (LCoE) was 0.099 $/kWh which relatively smaller than grid cost of 0.155 $/kWh. Therefore, this paper presents part of the solution for the persistent power outages and also overcomes the serious power problems during dry season in Malawi.</p> Sylvester William Chisale, Sylvester Richard Chikabvumbwa, Lackson Chisanu ##submission.copyrightStatement## Mon, 29 Jun 2020 00:00:00 +0000 Consumer Preferences for Cooking and Lighting Fuels and Domestic Energy Transition: A Nyeri Town, Kenya, Perspective <p>Improving access to modern fuels in developing countries is crucial in mitigating unfavorable environmental and health impacts caused by the continued use of traditional fuels. Use of modern fuels lead to improved standards of living and gender equity of women and children. This paper estimates preferences for domestic fuels and reasons thereof by households in urban areas in Nyeri town, Kenya. The study uses Nyeri town micro-data to perform correlation analysis to determine the relationship between fuel preference and domestic energy transition. Transition is considered along three categories of domestic fuels: traditional -firewood and charcoal; transitional fuels- kerosene; modern fuels – Liquefied Petroleum Gas (LPG), biogas, solar and grid electricity. The result findings show that urban residents use traditional, transitional and modern fuels through energy stacking theory with the transition to modern fuels following a consistent pattern. The major reasons for fuel preference were established as fuel convenience, affordability, ease of accessibility and cultural beliefs by 46.5%, 37.2%, 10.5% and 5.8% of the respondents respectively.</p> Peterson Murimi Nyaga, Anne Sang, Mariita Bw’Obuya, Simon Maina Mundia ##submission.copyrightStatement## Tue, 07 Jul 2020 00:00:00 +0000
