Malawi's poor electrification rate can be improved through the maximum utilization of available renewable energy resources. Malawi has several rivers which can be utilized for electricity generation. However, most rivers such as Lichenya are not utilized to its full capacity. This paper presents the theoretical designing of a pelton turbine for Lichenya River in Malawi for maximum generation of electricity. Hydropower plants can either be impoundment, diversion or pumped storage type. The turbine used for any type of plant depends on the available head and river flow rate. The hydraulic turbines are classified into impulse turbines and reaction turbines. Pelton turbine is under impulse turbines and are usually associated with very high head and low discharges with low specific speeds. Additionally, Pelton turbine is simple to manufacture, are relatively cheap, and have good efficiency and reliability. The river flow data for Lichenya River were collected from the Ministry of Irrigation and Water Development in Malawi. The design flow of 3.2 m 3 /s for the river was determined form the data. The river is within the catchment area of 62.3 km 2 and gross head of 304 m. The calculation of dimensions were carried out with the aid of EES software and spreadsheet. The designed turbine can generate 8067 kW of power with a turbine hydraulic efficiency of 95.4%. The detailed dimensions of the bucket, runner, penstock, and nozzle are presented. Therefore, this study can be the best guideline for further energy developments on Lichenya River in Malawi.

“…However, the utilization of low head micro hydropower installations presents an appealing and efficient approach for generating electricity, particularly in rural, remote, and hilly regions. This is due to the escalating levels of greenhouse gas emissions and fuel prices in such areas, rendering these micro hydropower systems increasingly favored for deployment along small rivers [10][11][12][13][14].…”

This feasibility study aims to assess the potential of implementing a micro hydro system in Lalumpe Village, located in North Sulawesi, Indonesia. The study focuses on evaluating the technical and economic aspects of the proposed micro hydro project. Data collection was carried out through field surveys, interviews with local stakeholders, and analysis of available hydrological and topographical data. The technical assessment involved conducting a resource assessment to determine the water availability and potential for harnessing hydroelectric power in the area. The study also examined the village’s energy demand and determined the suitable capacity of the micro hydro system required to meet the community’s needs. Economic analysis included estimating the initial investment costs, operation and maintenance expenses, and potential revenue generation from the sale of excess electricity to the local grid. Financial viability indicators such as payback period and net present value were calculated to assess the economic feasibility of the project.

“…It was observed the runner diameter by 1.25 m, hub diameter 0.3 m. do Nascimento et al [12] investigated the performance of an Indalma hydro turbine (small hydroelectric plants (CERPCH/UNIFEI-MG-Brazil).). It was observed the 80.8% efficiency at flow rate of 0.012 m 3 /s Prodanovic et al [13] studied the determination of operating parameters of turbine for micro hydroelectric power plant for optimal use of hydropower. It was stated that the higher head means a low discharge is required for same output power and efficiency.…”

Experimental investigations of 3.75 kW Pico Kaplan turbines have been carried out in this communication. The turbine is utilized for the experimental purpose for the students and it is procured under TEQIP-III project of World Bank. The load test of the turbine has been done which run at 50% capacity and presented the main and operating characteristic curves. It is observed that the efficiency of the turbine will improve at low speed, high brake power and high discharge. The discharge is also depending on the available head and the quantity of water. So, the turbine efficiency is also improved with respect to increasing the discharge. At the increasing the specific speed the discharge will also be increased linearly. The Pico Kaplan turbine can be used for runways water likes in Canals, rivers and no dam is required. The basic design is very simple and it is very common because it has vast applications for small, pico and micro power generation. It can be used in lot of regions like Himachal, Uttarakhand, Jammu & Kashmir, Eastern State (Assam, Arunachal Pradesh, Meghalaya, and Manipur), Punjab, Karnataka, Kerala, West Bengal, Maharashtra and Rajasthan states of India. This study will be useful for the researcher in the area of small hydro power plants.
