City of Cape Town electricity rates increased by an average of 6.64% for the 2026/27 financial year, with the new tariffs taking effect on 1 July 2026. What a City-supplied household pays depends on its tariff, electricity use, meter type and applicable monthly charges. This guide explains the current rates, eligibility rules and bill calculations, along with the main factors affecting costs and practical ways to manage them.
Key Takeaways
City of Cape Town residential electricity rates increased by an average of 6.64% for 2026/27, effective from 1 July 2026.
Lifeline, Domestic, Home User and Residential TOU have different rates, eligibility rules and monthly charges.
Qualifying Lifeline properties may receive 25 kWh or 60 kWh of Free Basic Electricity.
Domestic and Home User apply Block 2 above 600 kWh; splitting purchases does not reset Block 1.
Residential TOU may suit properties able to move substantial use to lower-cost periods, but fixed charges also apply.
What Are the City of Cape Town Electricity Rates for 2026/27?
From 1 July 2026, City-supplied residential energy rates are 283.04 c/kWh on Lifeline, 413.79–493.90 c/kWh on Domestic and 355.95–469.06 c/kWh on Home User. Residential TOU rates range from 300.94 to 893.23 c/kWh depending on the season and time of use.
The rates below include VAT and apply only to properties supplied directly by the City of Cape Town. Eskom-supplied properties follow different tariffs.
Current Residential Electricity Rates
Tariff | Energy rate incl. VAT | Monthly charge(s) incl. VAT |
Lifeline | 283.04 c/kWh | None |
Domestic | Block 1: 413.79 c/kWh Block 2: 493.90 c/kWh | R74.77 Services and Wires Charge |
Home User | Block 1: 355.95 c/kWh Block 2: 469.06 c/kWh | R424.30 Services and Wires Charge R6.80 AMI fee where applicable |
Residential TOU | Varies by season and time | R396.16 Administration Charge R288.48 Capacity Charge R6.80 AMI fee |
One electricity unit is equal to 1 kWh. Lifeline uses a single paid energy rate and provides qualifying households with 25 kWh or 60 kWh of Free Basic Electricity. Domestic and Home User use the Block 1 rate for the first 600 kWh received in a calendar month and the Block 2 rate for any units above 600 kWh.
The energy rate is only one part of the monthly cost. Home User has lower energy rates than Domestic but a much higher Services and Wires Charge, so comparing the per-unit rates alone can be misleading.
Residential TOU works differently because it has no 600 kWh blocks. Its energy rates change by season and time of use, as shown below.
TOU period | High-demand rate (June–August, incl. VAT) | Low Demand rate (September–May, incl. VAT) |
Peak | 893.23 c/kWh | 418.54 c/kWh |
Standard | 369.29 c/kWh | 355.60 c/kWh |
Off-peak | 300.94 c/kWh | 300.94 c/kWh |
The rates above include VAT. The applicable time periods are:
Monday–Friday
Peak: 07:00–09:00 and 18:00–21:00
Standard: 06:00–07:00, 09:00–18:00 and 21:00–22:00
Off-peak: 22:00–06:00
Saturday
Standard: 07:00–12:00 and 18:00–20:00
Off-peak: 00:00 – 07:00, 12:00 – 18:00 and 20:00 – 00:00
No peak period
Sunday
Standard: 18:00–20:00
Off-peak: 00:00 – 18:00 and 20:00 – 00:00
No peak period
The same time periods apply throughout the year, but peak and standard rates change between the high- and low-demand seasons.
Residential TOU may suit households that can move substantial electricity use—such as geyser heating, pool pumps, laundry or battery charging—into standard or off-peak periods. The three monthly charges and expected peak-period use should also be considered, as the lower off-peak rate alone does not determine the total cost.
Which Residential Tariff Applies to You?
The applicable tariff depends mainly on your meter type, municipal valuation, applicable rebates and average electricity received over the previous 12 months.
Lifeline: Generally applies to properties with a prepaid meter, a municipal valuation of R500,000 or less and a 12-month average below 450 kWh, including free electricity.
If you qualify, you receive:
60 kWh of Free Basic Electricity when the 12-month average is below 250 kWh;
25 kWh per month when the average is above 250 kWh but below 450 kWh.
The property valuation condition falls away if you receive a qualifying pensioner or disabled persons rebate, are a tenant who would otherwise qualify for such a rebate, or are registered as indigent. You must still meet the prepaid meter and electricity limits.
Domestic: Generally applies to households using prepaid electricity where the property’s municipal valuation is above R500,000 but below R1 million. It may also apply if you would otherwise qualify for Lifeline but receive more than 450 kWh per month on average over 12 consecutive months.
Home User: Applies to properties with a conventional credit or AMI meter, regardless of valuation. It also applies to prepaid properties valued at R1 million or more.
Residential TOU: Available on request to residential properties with an AMI meter. The property owner or an appointed proxy must submit a written request, which is subject to eligibility and metering checks. The tariff is available with or without approved Small-Scale Embedded Generation.
Residential customers with approved SSEG are charged on Home User unless they request and qualify for Residential TOU.
Check your municipal account to confirm your current tariff. If you believe it is incorrect, contact the City to request an assessment.
How Are Cape Town Electricity Charges Calculated?
Your electricity charge is not always calculated by multiplying all units by a single rate. The calculation depends on your tariff, the number of units received and any Free Basic Electricity or monthly charges that apply.
How Is Each Residential Tariff Calculated?
Lifeline
If you qualify, the applicable Free Basic Electricity allocation is deducted from the units received before the remaining units are charged.
Paid energy cost = (units received − Free Basic Electricity) × Lifeline rate
For example, if you receive 250 kWh and qualify for 60 kWh of Free Basic Electricity: (250 − 60) × R2.8304 = R537.78
There is no Services and Wires Charge on the Lifeline tariff.
Domestic and Home User
Both tariffs charge the first 600 kWh received in a calendar month at the Block 1 rate. Only the portion above 600 kWh is charged at the higher Block 2 rate.
For consumption above 600 kWh, the calculation is:
(600 kWh × Block 1 rate) + (remaining kWh × Block 2 rate) + applicable monthly charges
At 800 kWh, the indicative monthly cost is:
Domestic: (600 × R4.1379) + (200 × R4.9390) + R74.77 = R3,545.31
Home User: (600 × R3.5595) + (200 × R4.6906) + R424.30 = R3,498.12
Add the R6.80 AMI Administration Fee to Home User where applicable.
For Domestic prepaid electricity, the Services and Wires Charge is recovered through electricity purchases according to the number of days since the previous purchase. All units purchased within the same calendar month count towards the same 600 kWh block, so splitting a purchase into smaller transactions does not restart Block 1.
Residential Time-of-Use
Residential TOU does not use the 600 kWh block. Electricity used during peak, standard and off-peak periods is calculated separately at the applicable seasonal rate:
Total electricity cost = peak usage cost + standard usage cost + off-peak usage cost + monthly charges
A single monthly example would not be representative because two households using the same total number of units can pay different amounts depending on when that electricity is used. The balance between peak and off-peak consumption is therefore particularly important when estimating a Residential TOU bill.
Indicative Monthly Costs by Tariff
The City provides the following indicative monthly account costs at selected consumption levels:
Units received | Lifeline | Domestic | Home User |
250 kWh | R537.78 | R1,109.25 | R1,314.18 |
450 kWh | R1,202.92 | R1,936.83 | R2,026.08 |
600 kWh | R1,627.48 | R2,557.51 | R2,560.00 |
800 kWh | — | R3,545.31 | R3,498.12 |
These examples show that the energy rate alone does not determine the monthly cost. Lifeline figures apply only to qualifying households, with the 60 kWh FBE included in the total units shown. Home User examples exclude the R6.80 AMI Administration Fee where applicable. At 800 kWh, Home User is slightly cheaper than Domestic because its lower energy rates offset the higher fixed charge.

What Affects Your Electricity Bill in Cape Town?
A City-supplied property’s monthly electricity cost is determined by its rate structure, total consumption, meter arrangement and, in some cases, when power is used.
1. Annual Tariff Adjustments
The city reviews electricity prices through its annual budget process. For 2026/27, residential energy tariffs rose by an average of 6.64%, partly reflecting Eskom’s 9.01% bulk purchase increase for local authorities and the cost of operating the municipal network. Individual rates and charges may differ from this average.
2. Residential Tariff Type
Lifeline, Domestic, Home User and Residential TOU combine energy rates, eligibility rules and monthly fees in different ways. Lifeline includes Free Basic Electricity for qualifying properties, while Home User offers lower unit rates than Domestic but carries a higher Services and Wires Charge. The lowest per-kWh rate therefore does not always produce the lowest bill.
3. Monthly Electricity Consumption
Domestic and Home Users charge the first 600 kWh received in a calendar month at Block 1 and any additional units at Block 2. Prepaid purchases made during the month are combined, so buying smaller amounts more frequently does not reset the lower block. Appliances such as geysers, heaters, pool pumps and tumble dryers can have a notable effect on whether consumption exceeds the threshold.
4. Fixed Charges and Meter Type
Services and Wires, Administration, Capacity and AMI charges may be added depending on the rate category and meter installed. These costs remain relevant even in a low-consumption month. Meter type also helps determine whether a property falls under Domestic, Home User or is eligible to request Residential TOU.
5. Time of Use
Only Residential TOU changes the energy rate according to season and time of day. Peak electricity is particularly expensive during the high-demand winter months from June to August, so flexible loads can be moved to standard or off-peak periods where practical. Lifeline, Domestic and Home User prices do not vary by time, making load shifting less relevant to their energy charges.
How to Reduce the Cost of Electricity in Cape Town?
Reducing electricity costs requires more than simply using less power. By understanding energy usage and adopting practical solutions, households can find effective ways to manage their electricity expenses and improve energy efficiency.
1. Review Your Account and Usage
Confirm the tariff, units and fixed charges shown on the municipal account. Eligible properties may qualify for Lifeline and Free Basic Electricity, while an incorrect tariff can materially change the amount due. Residents can check water and electricity bill online through the City’s e-Services platform and compare recent accounts for unusual changes in consumption.
2. Prioritise Higher-Consumption Loads
Focus on geysers, heaters, tumble dryers, dishwashers and pool pumps rather than relying mainly on small standby savings. Practical measures include limiting unnecessary water heating, using full laundry loads and shortening pool-pump operating times.
Domestic and Home User charge units above 600 kWh at Block 2. Reducing the total received during the calendar month may therefore keep more consumption within Block 1; splitting prepaid purchases does not reset the threshold.
3. Use TOU Periods and Battery Storage Strategically
Residential TOU allows flexible loads such as geyser heating, laundry, pool pumps and battery charging to be moved from peak periods to cheaper standard or off-peak hours. This strategy does not offer the same time-based benefit on Lifeline, Domestic or Home User because their energy rates remain unchanged throughout the day.
Battery storage can help households manage electricity costs more effectively under Residential TOU. A portable power station with scheduled charging and discharging can store electricity during lower-cost periods and supply selected devices when peak rates apply. Potential savings will depend on the energy shifted, charging losses and the tariff’s monthly charges.
For households on Residential TOU that want to shift a moderate amount of electricity away from peak periods, the EcoFlow DELTA 3 Max offers 2048Wh of storage and app-based timed charging and discharging. Users can schedule the unit to recharge during lower-cost periods and supply selected appliances when peak rates apply, while the EcoFlow App provides visibility into energy use and solar generation. Its 2400W AC output also makes it suitable for a wider range of planned household loads than small battery packs.
For households that want to shift a larger share of their Residential TOU consumption, the EcoFlow DELTA Pro 3 starts with 4096Wh of storage and can expand to 12kWh. Its 4000W AC output supports multiple or higher-power household loads, making it more suitable where the aim is to reduce a broader portion of peak-period grid use rather than power only a few selected devices. App-based monitoring also helps households understand how stored energy is being used and adjust their energy strategy over time.
4. Consider Approved Solar PV
Solar PV may reduce grid purchases when daytime generation matches demand, while compatible storage can make some of that energy available later. Results depend on system cost, solar yield and the property’s load profile, so savings are not automatic.
SSEG installations within the City’s supply area require authorisation before installation. Permanently connected solar or battery equipment should also meet municipal requirements and be installed by qualified professionals.
Conclusion
Managing bills under City of Cape Town electricity rates starts with confirming that the property is City-supplied and checking the tariff on the municipal account. Domestic and Home User properties should reduce total monthly units rather than split prepaid purchases, as this does not reset Block 1. Before choosing Residential TOU, compare its fixed charges and assess whether loads such as geysers, laundry or battery charging can be moved out of peak periods.
FAQs
How much electricity can I buy for R500?
It depends on your residential tariff. At the 2026/27 rates, R500 buys approximately 177 kWh on Lifeline, 121 kWh on Domestic Block 1 or 140 kWh on Home User Block 1. The actual token may include fewer paid units if service charges, arrears or Block 2 rates apply.
What is the best day to buy electricity in Cape Town?
There is no cheaper day to buy prepaid electricity. Buying on the first day of the month does not provide a lower rate, and eligible free units are issued with the first purchase made during that calendar month. The City recommends buying only the electricity needed for that month.
Is prepaid electricity cheaper in Cape Town?
Not necessarily. Prepaid and credit meters have the same cost per kWh when they are on the same tariff. A prepaid meter mainly makes it easier to monitor usage and manage spending, although qualifying prepaid households may receive the subsidised Lifeline tariff.
