What You'll Learn
- The number of units of electricity you can buy with R400 depends on the tariff scale
- In South Africa, R400 can buy 147.55 units of electricity, excluding VAT
- The City of Johannesburg offers different rates for prepaid and post-paid customers

The number of units of electricity you can buy with R400 depends on the tariff scale
The number of units of electricity that R400 will buy depends on several factors, including the area, municipality, property value, electricity supplier, and current. For example, in Johannesburg, the City Power basic charge for prepaid electricity is R200, which would leave R200 to purchase electricity units. According to City Power, if a customer buys electricity for the first time in a month with R300, R40 will be deducted for VAT, and the remaining R260 will be split evenly between the fixed charge and purchasing electricity units.
Electricity pricing plans, also known as tariffs, vary depending on the type of customer, such as residential, commercial, or industrial. Tariffs can also differ based on the amount of energy used, the type of meter, and whether it is a peak or off-peak time. For instance, a flat or single-rate tariff charges a constant amount for electricity usage, whereas a time-of-use tariff varies depending on the time of day, with higher rates during peak periods.
The number of units of electricity that R400 can purchase also depends on the specific tariff structure set by the distributor. For example, in Johannesburg, prepaid customers are divided into three blocks: the first limited to 350 kWh, the second up to 500 kWh, and the third block for customers exceeding 500 kWh. The rates for each block are R2.01, R2.40, and R2.73, respectively. Therefore, R400 would purchase 166 units in the first block, 166 units in the second block, and 147 units in the third block.
Additionally, the number of units purchased can be influenced by the customer's property value. For instance, customers with properties valued between R400,000 and R1 million pay R2.98 per unit for the first 600 units and R3.63 for additional units. On the other hand, customers with properties valued above R1 million may be on a post-paid plan and pay a rate of R2.63 for the first 600 units and R3.63 for further units, along with a service charge of R212.75.
It is important to note that these rates may change over time, and different locations will have different tariff structures.

In South Africa, R400 can buy 147.55 units of electricity, excluding VAT
In South Africa, the cost of electricity per unit is not fixed. The amount of electricity you can buy depends on several factors, including your location, the municipality, the price of your house, the electricity supplier, and the current. For example, in Johannesburg, electricity tariffs are subject to a 12.7% increase.
The Inclining Block Tariff (IBT) system is used to determine the cost of electricity per unit. The IBT system is designed so that the more energy you consume monthly, the higher the amount you will pay for each unit of electricity. This system also encourages users to conserve electricity.
According to the IBT system, for monthly electricity usage below 350 units (Block 1), the cost of 1 unit of electricity is R2.2162/kWh (without VAT). Therefore, R400 can buy 147.55 units of electricity, excluding VAT.
It is worth noting that there is a special electricity rebate program for indigent citizens and residents facing financial challenges, where they pay less for each electricity unit they consume. Additionally, qualifying citizens can access Free Basic Electricity (FBE) and register for the Expanded Social Package (ESP) rebates.

The City of Johannesburg offers different rates for prepaid and post-paid customers
The City of Johannesburg offers varying rates for prepaid and post-paid customers. Prepaid customers are split into three blocks, each with a different rate per kilowatt-hour (kWh). The first block is limited to 350 kWh and is charged at R2.01 per kWh. The second block covers up to 500 kWh and is charged at R2.40 per kWh. Any usage above 500 kWh falls into the third block, which is charged at R2.73 per kWh. These rates include Value Added Tax (VAT).
In comparison, post-paid customers on a single-phase (60A) supply will pay a connection fee of R1070 per month, while those on three-phase supplies will pay R1365 per month. These fees are independent of electricity usage. The rate per unit of electricity for post-paid customers is not clearly stated, but it is suggested that post-paid electricity becomes more affordable than prepaid when a household consumes a large amount of electricity.
It is worth noting that Johannesburg has introduced a R200 basic charge for prepaid customers, which includes a R70 service charge and a R130 network capacity charge, exclusive of VAT. This means that even without purchasing any electricity units, prepaid customers will be charged R200.
The number of units of electricity that R400 will buy depends on the block that a customer falls into. For example, a customer in the first block will pay R2.01 per unit, so R400 will buy 199 units (with R1 left over). In contrast, a customer in the third block will pay R2.73 per unit, so R400 will buy 146 units (with R14 left over).
The City of Johannesburg also offers Free Basic Electricity (FBE) for qualifying citizens, which is available to those with an income of R6,281.13 or less.

The price of electricity per unit is not fixed; it depends on the inclining block tariff system
The price of electricity per unit is not fixed and depends on the inclining block tariff system, which was invented by Eskom/NERSA to make electricity affordable for those who use little and discourage overconsumption. The electricity price per unit is divided across several blocks, with the first block being the cheapest price per unit, but with a maximum quantity of units that can be bought at this rate. Once the maximum number of units has been purchased at the lowest rate, the consumer moves to the next block, which is a more expensive rate per unit, and so on.
For example, for customers on 60-amp current, the lowest-rated payment block would be from zero to 600 units at R1.82 per unit. Once 600 units have been purchased, the rate increases to R3.10 per unit for the rest of the month, resetting to the lower rate at the beginning of the following month. This means that the price of electricity per unit is not fixed and will depend on how many units have already been purchased.
The exact price a consumer pays for a unit of electricity also depends on several other factors, including the area, municipality, the price of the house, the electricity supplier, and the current. For instance, in Johannesburg, prepaid customers are split into three blocks: the first is limited to 350 kWh, the second goes up to 500 kWh, and everyone above that falls into the third block. The VAT-inclusive rates also differ per block, at R2.01, R2.40, and R2.73, respectively.
Additionally, in Johannesburg, residential prepaid customers are subject to a R200 basic charge, which consists of a R70 service charge and a R130 network capacity charge, exclusive of VAT. This means that even if no prepaid electricity units are purchased, this charge will still apply.
Therefore, the price of electricity per unit is not fixed and is dependent on a variety of factors, including the inclining block tariff system, location, and additional charges.

The cost of electricity also depends on factors like area, municipality, and house price
The cost of electricity is influenced by several factors, and it can vary significantly depending on one's location and specific circumstances. While the amount of electricity consumed is a significant factor in determining the cost, other factors such as area, municipality, and house price also play a role.
Area
The location of one's residence can impact the cost of electricity. Prices can vary by locality based on the availability of power plants and fuels, local fuel costs, and pricing regulations. For example, in the United States in 2022, the annual average retail electricity price ranged from 39.85 cents per kilowatt-hour in Hawaii to 8.24 cents per kilowatt-hour in Wyoming. Hawaii's prices are relatively high due to its reliance on imported fossil fuels and the higher costs associated with operating and maintaining power plants in a tropical environment.
Municipality
The municipality or local regulatory environment can also influence electricity rates. Different municipalities may have different pricing structures and tariff systems. For instance, the City of Johannesburg in South Africa offers a tiered system for prepaid and post-paid customers, with varying rates for different blocks of electricity consumption.
House Price
In some cases, the price of one's house can be a factor in determining electricity rates. Certain municipalities or utility providers may have different rates based on property values. For example, in the context of Eskom's block tariffs, customers with a municipal property evaluation between R400,000 and R1 million pay a different rate for electricity compared to those with properties valued above R1 million.
It's worth noting that other factors, such as the electricity supplier, current, time of year, and energy efficiency practices, can also impact the cost of electricity. Additionally, the cost of generating electricity, including fuel prices, power plant costs, transmission and distribution system costs, and external costs like environmental impact, all contribute to the overall price of electricity for consumers. Understanding these factors can help individuals make informed decisions about their electricity usage and explore ways to optimize their energy consumption and costs.
