Electricity infrastructure (generation plants, and network assets) are available to be utilized almost uniformly across a 24-day cycle. However, these assets have a limited capacity as to the amount of electrical load carried. Therefore, efficient utilization of these resources requires that as much energy from these assets is made available for customers so that the costs of these assets is spread across more output (energy). Energy from these assets can be best maximized if the highest reasonable capacity is utilized every hour of the day.

Therefore, customers are encouraged either to consume evenly across every hour of the day or even reduce consumption during peak periods. However, given that domestic customers are only mainly at home (and awake) at peak time, the electricity utilization of domestic customers is maximum at the peak, and these customers have minimal flexibility to increase their consumption at a non-peak period. It may, therefore, be unreasonable to subject domestic customers to ToU signaling.

Besides, domestic customers in Uganda use electricity for limited applications which limits the need to roll out expensive ToU metering devices that impose a significant additional cost.
