Understanding which tariff applies to you is the first step in managing electricity costs and identifying opportunities to save.
Types of City Power Tariffs
City Power offers different electricity tariffs tailored to the needs of residential and business users. Understanding these tariff types can help you manage your consumption and reduce electricity costs.
1. Residential Tariffs
Residential customers typically fall into three main categories:
Prepaid Electricity Tariffs
Customers purchase electricity in advance using a prepaid meter.
Helps manage budgets and avoid bill surprises.
Tariffs may be slightly higher per kWh compared to postpaid rates.
Ideal for low to medium household electricity usage.
Postpaid / Standard Residential Tariffs
Bills are calculated monthly based on actual electricity consumption.
Often uses tiered pricing: higher usage leads to higher per kWh rates.
Suitable for households with predictable electricity usage patterns.
Time-of-Use (TOU) Tariffs
Rates vary depending on when electricity is consumed.
Peak hours: higher cost per kWh
Off-peak hours: lower cost per kWh
Encourages households to shift energy-intensive activities, like laundry or geyser heating, to off-peak times.
2. Business Tariffs
Businesses face more complex tariffs due to higher consumption and operational requirements.
Small Power Users
For businesses with low to moderate electricity usage.
Categorized into small, medium, or ultra-low consumption.
May include fixed daily charges plus energy charges per kWh.
Large Power Users (Time-of-Use Tariffs)
For high-consumption businesses.
Energy charges vary by time of day: peak, standard, and off-peak.
Encourages shifting consumption to off-peak periods to save costs.
Special Tariffs: Feed-In Tariff
Businesses or homeowners generating renewable energy (e.g., solar) can feed surplus electricity back into the grid.
City Power provides financial incentives per kWh fed back.
Supports sustainable energy adoption while reducing net electricity costs.
Once you understand the tariff types, it’s important to know how your bill is calculated.
How Are City Power Tariffs Calculated?
Understanding how City Power tariffs are calculated can help you take control of your electricity costs and plan your consumption more efficiently. The final electricity bill is determined by a combination of factors, including consumption, tariff type, and additional charges.
1. Consumption-Based Charges
The primary component of your electricity bill is the per kilowatt-hour (kWh) rate. Residential and business users may have tiered or time-of-use (TOU) pricing:
Tiered Pricing: You pay a standard rate for the first block of electricity (e.g., 0–600 kWh), then a higher rate for usage beyond that.
Time-of-Use (TOU) Pricing: Rates vary depending on the time of day. Electricity used during peak hours costs more, while off-peak usage is cheaper.
To estimate your bill accurately, it’s important to track the electricity cost per kWh for your specific tariff and consumption pattern.
Example for residential TOU:
Time of Use | Rate per kWh (R) |
Peak | 4.75 |
Standard | 3.44 |
Off-Peak | 2.37 |
2. Fixed or Service Charges
Many City Power tariffs include a fixed daily or monthly service charge, which covers infrastructure maintenance, meter reading, and administrative costs. This charge is applied regardless of electricity consumption.
Example:
Home User Tariff: R281.78 per month (including VAT)
3. Demand Charges (Business Tariffs)
For commercial users, particularly large businesses, demand charges may apply. This is based on the highest level of electricity demand (kW) during the month, ensuring that the grid can handle peak consumption.
4. Prepaid vs Postpaid Calculations
Prepaid Electricity: You purchase a set amount of electricity in advance. The meter deducts units as you consume them, allowing for better budget management.
Postpaid Electricity: Your usage is recorded monthly, and your bill is calculated based on total consumption, tiered rates, and service charges.
5. VAT and Additional Fees
All City Power tariffs include VAT (currently 15%), and other municipal fees may apply depending on your location or property type.
By understanding these calculation methods, you can optimize your electricity usage—shifting high-consumption activities to off-peak times, reducing unnecessary demand, saving electricity, and choosing the tariff plan that best suits your needs.
Factors Affecting City Power Tariffs
The cost of electricity supplied by City Power is influenced by multiple factors, which can affect both residential and business users. Understanding these factors can help you anticipate fluctuations and make smarter energy decisions.
1. Cost of Generation
Most of South Africa’s electricity comes from coal-fired power plants operated by Eskom, while City Power also sources some electricity from the national grid. Changes in coal prices, fuel costs, or renewable energy investments can directly impact City Power electricity tariffs.
2. Transmission and Distribution Costs
Electricity must travel through substations, transformers, and power lines before reaching your home or business. Maintenance, upgrades, and losses during transmission all contribute to the final cost. Cities with older infrastructure may face higher distribution costs, reflected in tariffs.
3. Time of Use and Demand
The time you consume electricity affects how much you pay. Peak-hour usage costs more due to higher demand and reliance on more expensive generation methods. For businesses, high demand periods may also incur additional demand charges, increasing the overall electricity bill.
4. Regulatory and Policy Decisions
City Power tariffs are regulated by municipal policies and are influenced by Eskom’s pricing and Nersa (National Energy Regulator of South Africa) approvals. Any tariff adjustments, environmental levies, or taxes can directly affect your electricity costs.
5. Consumption Patterns
Your household or business consumption habits play a significant role. Higher usage or inefficient appliances can push you into higher tariff blocks, while energy-efficient practices can help reduce costs.
6. Renewable Energy and Feed-In Tariffs
Users generating renewable energy (like solar) may benefit from feed-in tariffs when excess electricity is fed back into the grid. This can offset some of your electricity costs and reduce reliance on the main supply.
Knowing the factors influencing tariffs can help you apply practical strategies to save money.
Tips to Save Money on City Power Tariffs
Cutting your electricity bill isn’t only about using less power—it’s about using it smarter. Here are practical ways to reduce costs while staying prepared for Johannesburg’s load-shedding challenges:
