In 2, the plant was billed about R9.8 million for elec tricity usage. The consumption accounted for about R7 million (approximately 7%) with the balance being demand and fixed charges. On average about R5,0 and R2,0 was billed for consumption and demand charges respectively.

Peak period charges also contributed the highest percentage of the cost at 4-4%. During the low demand season, standard and off peak charges were higher. 4-1 4.5.6 Energy Split The total electricity consumption and billed cost distr ibution by treatment unit/functional area for the plant is shown in Table 4-9. There were no records of power usage by the main units at the plant. Aeration power use was theoretically calculated using modelling and the power consumption for the other units was allocated based on duty motor sizes. It was recommended to the City of Tshwane that they keep records of run times as well as power an current drawn by the main units as part of the operation and control of the plant. graphical representation of the electricity consumption split is shown in Figure 4-9.
