Eskom direct customer adjustment / municipal bulk supply adjustment for 2026–27
Eskom direct customers and municipal electricity customers face different implementation dates and approved increases. Fixed charges, tariff structures and household consumption matter as much as the national headline.
Distinguish observed facts from projections, arguments and interpretations.
The first question is who supplies your electricity
Eskom announced an average approved adjustment of 8.76% for its directly supplied customers effective 1 April 2026. Bulk electricity purchased by municipalities faced an average 9.01% adjustment from 1 July 2026, reflecting the different municipal financial year. These two figures are often reported together but they are not identical charges on the same customer. A household billed by its municipality generally pays the municipality’s applicable retail tariff, whose structure and approval process differ from Eskom’s bulk supply price. A customer must therefore identify the billing authority before using the headline percentage.
An average tariff adjustment is not your personal bill percentage
A tariff schedule can change energy charges per kilowatt-hour, fixed service charges, capacity-related components and different time-of-use rates at different percentages. An individual bill is determined by the particular tariff code, metered consumption, timing and applicable fixed or administrative charges. Eskom’s 2026–27 documentation also describes structural changes affecting the recovery of fixed costs through the Generation Capacity Charge and other service charges. As a result, even a home whose electricity use is unchanged need not see a precisely 8.76% increase in its final invoice.
Municipal customers face another layer of financial decisions
A city or municipality buys power, runs or maintains local distribution assets, serves customers and may have its own tariff design. The regulator’s approved increase in municipal bulk purchases is not the same as an assurance that each resident’s retail tariff rises by exactly 9.01%. Municipal pricing decisions can reflect losses, customer classes, service costs and approved structures. Residents should consult the actual published municipal tariff schedule for their area and compare the previous year’s corresponding tariff, rather than treating an Eskom press release as a complete residential price list.
What does this mean for households with rooftop solar?
Solar generation can reduce the kilowatt-hours purchased from the network at the times the panels produce electricity. But a tariff with material fixed or availability charges may still produce a substantial bill even when grid consumption falls. Export credits and wheeling or net-billing arrangements depend on the specific tariff, metering equipment and contract. Eskom’s price schedule discusses changes to the Generation Capacity Charge allocation and the treatment of energy credits, so using a simple “units avoided times retail rate” formula may exaggerate savings for some customers.
Why electricity policy cannot be separated from reliability
Households and small businesses evaluate both the price and dependability of supply. Even if electricity becomes more reliable, higher tariffs can squeeze spending or the viability of refrigeration, workshops and other electricity-intensive activity. Eskom says the decision arose from the regulator’s multi-year price process; that is a record of price regulation, not proof that every additional charge directly improves service or that all costs are avoidable. Comparing customer experience requires evidence about outages, network performance, consumption and bills across time.
A practical audit before comparing the next two bills
Find your supplier, tariff category, old and new unit prices, daily fixed charges, meter readings and billed days. If you are on prepaid supply, also distinguish credit purchased from electricity consumed in the period. A household with solar, a business on a time-of-use plan and a municipal apartment may all need different calculations. Check whether your municipality has published additional charges, then compare like-for-like annualised consumption rather than two months with different weather. These details are local and must be confirmed on the actual customer bill.
What the headline leaves out
The 8.76% average increase for Eskom direct customers and 9.01% for municipal bulk supply are both real, approved regulatory figures for 2026–27, but they are not guaranteed percentages on an individual household’s next statement. The retail tariff category, fixed generation-capacity and service charges, municipality and consumption level determine the result. The official price schedule also explains why prepaid bundles and home solar are not automatic ways to escape these charges.

The deeper investigation
1. Who sends the invoice changes which approved percentage is relevant
The National Energy Regulator of South Africa approved Eskom’s average 2026–27 increase after reviewing the utility’s Retail Tariff and Structural Adjustment application. Eskom direct customers entered the new financial year on 1 April 2026 with an 8.76% average tariff adjustment, while the municipal bulk-supply change of 9.01% took effect from 1 July. The distinction arises because municipalities operate on a July–June financial year and Eskom uses an April–March year. A municipal household therefore does not buy its electricity directly at Eskom’s published bulk price. Its municipality must recover local distribution, billing and other approved costs under the retail tariffs applicable in that city. Someone comparing the national 9.01% figure with their household bill must first check whether the account is issued by a local authority and what residential or business category applies. The percentage cannot be read as a national promise that every household in every municipality will pay exactly 9.01% more.
2. Averages can conceal large differences between customer categories
The official tariff schedule is a detailed document containing rate structures for Homepower, Homelight, Homeflex, time-of-use, business and industrial supplies. An average increase describes the regulatory outcome across a defined group of customer sales and revenue, not the increase in each component of each invoice. Some tariffs have fixed monthly or daily charges, some vary with usage, some feature seasonal or time-of-use prices, and large customers may be affected by capacity or demand charges. A household using just a small amount of electricity can see fixed fees form a higher share of its account than a high-usage household. The appropriate comparison holds consumption, tariff category and billing period constant while calculating every relevant old and new line item. Without the previous schedule and the current meter readings, a claim such as “you must pay 8.76% more per unit this month” can be misleading. Price increases and tariff restructuring can occur simultaneously while producing different effects on different customers.
3. The generation-capacity charge shift changes how costs are recovered
Eskom’s schedule specifies that the fixed portion of the Generation Capacity Charge rose from 20% in FY2026 to 30% in FY2027. The remaining 70% is recovered through the energy charge. This is an allocation change, not a statement that generation capacity itself increased by 10% or that the entire account rose ten percentage points. The purpose is to recover costs of backup generation and availability through a combination of capacity-linked and usage-linked components. Eskom also says that the part of the GCC included in the energy charge is excluded from the energy credits used in wheeling and offset transactions. This is important for customers who consume some power from rooftop solar or arrange another supplier: avoiding purchased energy does not necessarily eliminate the utility’s cost of maintaining available generation capacity. The effect on a specific household or factory depends on which tariff is selected, the available connection and the actual consumption profile.
4. Homepower and Homeflex service fees are shifting towards fixed recovery
For Homepower and Homeflex, the published schedule describes a three-year phase-in of service and administration charges. The fixed portion increased from 33.33% of the relevant service/admin amount in FY2026 to 66.66% in FY2027, leaving 33.34% recovered through energy charges. In a stylised example of a R90 service/admin charge, the fixed share would be roughly R30 in the earlier structure and R60 in the later structure, with the rest recovered as variable charges. That illustration does not mean the actual approved rand amount is R90 or that every household is billed an extra R30. The total level of service costs, volume and individual tariff terms also matter. A consumer who previously reduced their bill substantially by lowering kWh consumption may find the monthly payment falls less when more charges are fixed. Conversely, customers with higher usage may experience a different allocation. This is why the exact structural provisions deserve as much attention as the 8.76% average headline.
5. Rooftop solar lowers some purchases but does not erase grid availability costs
A household that generates solar electricity during the day can avoid purchasing some grid-supplied kilowatt-hours, especially when appliance demand overlaps with sunshine. But solar does not automatically sever the connection to the network or remove the need for backup on a cloudy evening. The Eskom FY2027 price schedule distinguishes the energy credit received through authorised offset or net-billing arrangements from the customer’s charges for network services and available capacity. Customers should verify tariff eligibility, metering, permitted export arrangements and how the Generation Capacity Charge is applied. A simple calculation that multiplies every unit of solar generation by the full retail tariff risks exaggerating savings where fixed costs remain or export credit is less than the import cost. Batteries may move consumption into the evening, but their upfront cost, limited capacity, round-trip losses and replacement obligations must also be considered. Any claim that solar owners now pay nothing to Eskom needs a real connection and billing assessment.
6. EasyElectricity purchase options support budgeting, not a cheaper tariff
Eskom’s official schedule introduces optional EasyElectricity packages for certain residential tariffs as an attempt to simplify the complexity created by unbundled tariff components. The utility specifically describes the purchase options as revenue-neutral and states that they do not provide a discount. For a Homepower option, fixed charges are first deducted from the customer’s purchase amount, and the remainder is converted into electricity units at the applicable variable rate. A customer who purchases a fixed number of rand therefore may receive fewer usable kilowatt-hours than expected if they treat the whole payment as variable energy. These purchase options can be helpful for planning how much to spend over a month, but they do not prove that selecting one reduces the annual cost compared with the standard underlying tariff under identical conditions. Consumers should read the number of included units, top-up rules, fixed charge deductions and any billing administration details before comparing offers.
7. Municipal electricity has a further layer of decisions and accountability
A municipality purchases electricity in bulk, operates or contracts local distribution infrastructure and bills its own customers under its published local schedule. Higher wholesale costs can create budget pressure, but residential retail tariffs also depend on distribution losses, maintenance, administration, customer-category cross-subsidies and local decisions subject to the applicable regulatory framework. Some towns have significant debt, infrastructure and service-delivery challenges that should not be blamed exclusively on the national 9.01% adjustment. Equally, it would be incorrect to assume the municipality is free to charge any amount without approval and oversight. A household should locate the official tariff table effective from July 2026 for its named municipality, identify the relevant block of monthly consumption and compare a like-for-like invoice. Where electricity is purchased through prepaid vending, transaction records and the number of units bought help establish whether perceived changes are due to tariff bands, fixed deductions or consumption.
8. Reliability, affordability and Eskom’s revenue need to be judged separately
An electricity supplier must recover costs sufficient to operate, maintain and invest in generation and networks, but customers reasonably expect those expenditures to support reliable, affordable service. South Africa’s history of load-shedding, financial strain and major capital projects makes both questions politically important. Regulators can balance permitted revenue, forecast demand and customer protection, yet an approved increase does not prove that outages will disappear or that every expenditure was unavoidable. Nor does the existence of a high utility bill on its own prove mismanagement. A proper evaluation compares cost items, audited financial reports, plant availability, municipal payment arrears, service quality and investment outcomes across comparable periods. Low-income households may be disproportionately affected by high fixed charges or small prepaid purchases, so affordability programmes and tariff category distinctions deserve scrutiny. The debate is not solved by selecting an average percentage and attributing every consumer experience to it.
9. A consumer audit of the 2026–27 bill requires more than one percentage
Start with the name of the billing entity, the supply location and the precise tariff code. Then locate the legally effective schedule for the month concerned, including separate fixed service fees, administration charges, energy rates, demand or capacity fees and applicable taxes. Compare the previous year’s same tariff at the same kWh volume, rather than comparing bills from months with different weather and appliances. If on a time-of-use option, allocate consumption across peak, standard and off-peak periods. If using rooftop solar, separately record on-site consumption, exports and any credited units. Eskom’s original PDF includes exact tariff tables for those who need to go beyond a simplified illustration. Future reporting should track any NERSA revisions and the relevant municipal tariff decisions, rather than reuse 8.76% as a universal customer-invoice prediction. The result may be more or less than the national average depending on how charges are allocated and what the household actually uses.
Illustrative bill: why an 8.76% average increase does not determine the final total
All rand rates and household scenarios below are deliberately invented. The 8.76% direct-customer and 9.01% municipal-bulk averages, and the fixed-cost restructuring percentages, are official. This is an arithmetic illustration, not an approved Homepower, Homelight or municipal tariff quote.
R2.00 per kWh is fictitious; used only to demonstrate a two-part electricity bill.
Selected for illustration, not Eskom’s actual approved service or GCC amount.
A simple two-part invoice independent of consumption timing.
A purely invented 5% variable-rate rise, different from the 8.76% national average.
Illustrates the effect of a larger fixed component, without claiming R140 is an approved rate.
The stylised invoice increases 10% despite an official 8.76% average across customers.
Compared with 300 kWh, variable use falls, but the hypothetical R140 fixed component remains.
Eskom says purchase options are optional and revenue-neutral; fixed costs may be deducted from a prepaid amount first.
None of the R2.00, R2.10, R100 or R140 figures is a regulated 2026–27 tariff. The difference between direct and municipal billing, fixed charge eligibility, consumption blocks, time-of-use arrangements, VAT and actual Eskom or municipal rates can change real results. Do not use this as a quote.
The arguments, and what evidence they need
These are possible interpretations, not invented quotations from people we did not interview.
Low-usage household concerned about rising fixed costs
I reduce my electricity use but still see substantial charges for staying connected.
What must still be established: The actual tariff and old/new component breakdown must be checked, rather than assuming the national average explains the difference.
Utility responsible for reliable standby capacity
The network and generation must be maintained even when customers buy fewer kilowatt-hours.
What must still be established: Necessary cost recovery and efficiency should be supported by audited expenditure, service quality and transparent tariff allocations.
Municipal consumer comparing bills
A 9.01% bulk increase does not tell me why my city’s retail account changed by another percentage.
What must still be established: A municipality’s approved retail table and its local distribution cost structure, losses and effective dates are required.
Frequently misunderstood details
Does every Eskom customer have an 8.76% higher household bill?
No. The 8.76% is the average approved direct-customer tariff adjustment, while actual tariffs include different fixed and variable components.
Do municipal households pay the 9.01% Eskom wholesale rate directly?
Not generally. Municipalities buy electricity in bulk and apply their own approved retail tariff structures.
When did the two increases start?
Eskom direct tariffs took effect 1 April 2026, and the municipal bulk supply increase took effect 1 July 2026.
Why can my bill remain high after I install solar?
A connected property may still pay service, administration, network and generation-capacity-related charges. Export credits also have specific tariff conditions.
Does EasyElectricity save money compared with an identical standard tariff?
Eskom describes the purchase packages as optional and revenue-neutral and explicitly says no discount is provided.
Can I calculate my new bill by multiplying the old total by 1.0876?
That may be a rough national-level comparison but is not a reliable individual bill calculation where component rates, consumption, fixed fees and tariff codes differ.
Which source has the exact current residential prices?
Eskom’s 57-page FY2027 schedule lists its approved tariffs, while municipal customers need their specific municipality’s published retail schedule.
