| Summary/Abstract |
Lesotho has a poverty rate above 50%, this renders a bulk of households connected to the grid unable to purchase enough energy to cover the essential basic needs at the current tariffs. This is supported by the declining average household consumption reported by Lesotho Electricity Company (LEC) despite an increasing customer base. Even more crucial, for low income countries, tariff levels should balance social stability, affordability, fairness, energy efficiency as well as cost recovery especially because the poor make up the majority of the population. Based on the poverty line, a lifeline tariff of 0.5 to 0.6 Maloti(M)/kWh (2017 tariffs) for a threshold of up to 30 kWh/month is proposed which is 35%–42% lower than the current domestic tariff of 1.424 M/kWh. The standard domestic tariff will need to increase to 1.856 M/kWh to allow for cross-subsidisation and hence maintain the financial standing of the utility company. The threshold capacity is based on the observation that in 2016, around 30% of grid connected households consumed less than 30 kWh/month which is enough electricity to cover the basic needs of an average household. Hence, an increasing block tariff (IBT) approach is proposed such that the first 30 kWh/month are set at a lifeline tariff and any excess is charged at a standard rate which is set such that it cross-subsidises the lifeline tariff.

| Summary/Abstract |
Renewable energy sources (RES) dominance in Uganda's electricity mix is challenged by affordability and theft. To assess electricity affordability, the study proposed a probabilistic method to quantify the households into different electricity categories for both urban and rural areas. Alternative electricity billing schemes based on Scenarios A to D for the households to enhance legal connection and consumption of electricity were proposed. The study established that the utility registers the highest electricity theft losses in rural households. The monthly utility revenue collected in urban areas was about 2.9 times that collected in rural areas because of the higher number of legally connected households with a monthly consumption of 1.5 times than that of rural households. From the monthly income spendable on electricity, rural and urban households could only afford 25.07 kWh and 38.29 kWh, respectively, which are less than the average household electricity consumption for Uganda. Also, the initial connection fee to the power grid is very high for the households to afford it in a single down payment. Of the proposed alternative billing schemes, Scenario B and Scenario D yield the least monthly utility revenue collected for the urban and rural households, respectively.
