Estate power supply in Nigeria often combines several systems: electricity from the Distribution Company, individual prepaid meters, shared transformers, central generators, inverters or solar systems.
The difficult part is not only keeping the lights on.
Management also needs a fair way to determine who consumed what, which costs belong to individual homes and which expenses should be shared by the whole estate.
Without proper metering and clear billing, electricity quickly becomes one of the biggest sources of disagreement between residents and the EXCO.
Should every house have its own electricity meter?
Where technically and commercially possible, individual metering gives each household the clearest picture of its own electricity use.
A resident can see:
- units purchased;
- electricity consumed;
- remaining credit;
- and how changes in usage affect their bill.
This is easier to understand than receiving one large estate electricity bill and being told to pay an equal share.
NERC's Customer Protection Regulations require electricity bills issued by Distribution Companies to be understandable and establish rules around customer metering and billing. (NERC)
NERC also states that customers have a right to transparent billing and properly installed functional meters. (NERC)
Metering remains an important issue nationally.
NERC reported that by the end of June 2026, approximately 7.74 million of Nigeria's 12.59 million active electricity customers were metered, representing a national metering rate of 61.51 percent. (NERC)
That means unmetered and shared-supply arrangements remain relevant in many communities.
For a resident considering a property, electricity should therefore be one of the first questions asked in what to check before renting in an estate.
How should a shared generator be billed?
A central generator is different from normal DisCo electricity.
The estate is buying diesel, maintaining equipment and generating backup power for residents and common areas.
Possible costs include:
- diesel;
- engine oil;
- servicing;
- generator operator;
- repairs;
- replacement parts;
- battery replacement;
- and eventual major overhaul.
Management needs to decide how those costs are allocated.
There are several approaches.
Equal household contribution
Every participating house pays the same amount.
This is simple but may feel unfair if electricity consumption differs greatly between homes.
Consumption-based billing
Sub-meters measure how much generator electricity each household uses.
Households consuming more units pay more.
Hybrid billing
Some generator costs are shared equally while consumption-related costs are allocated according to usage.
For example, regular maintenance may be treated as a shared fixed cost while diesel usage is allocated through meter readings.
There is no single formula that fits every estate.
The important thing is that residents understand the method before the bill arrives.
The estate should also separate generator management from ordinary service-charge assumptions.
Read how to manage estate generators and diesel for the operational side.
How can an estate calculate generator electricity costs?
Start with the real costs for the billing period.
For example, suppose the estate records:
Diesel: N3,000,000
Maintenance: N400,000
Operator and related costs: N300,000
Other generator expenses: N300,000
Total:
N4,000,000
Now suppose the estate has metered household generator consumption and common-area consumption separately.
Households consumed:
16,000 kWh
Common areas consumed:
4,000 kWh
Total recorded generator consumption:
20,000 kWh
A simple cost-allocation calculation would be:
N4,000,000 divided by 20,000 kWh = N200 per kWh
This is only an example.
It is not a recommended Nigerian generator tariff.
Actual generator cost depends on:
- generator efficiency;
- diesel consumption;
- load;
- maintenance condition;
- diesel price;
- operating hours;
- and other estate expenses.
The important thing is that management can show how the figure was calculated.
If a house consumed 250 kWh during the period in this example:
250 multiplied by N200 = N50,000
Residents can now connect their consumption to the amount being charged.
If management simply announces:
Generator bill this month is N75,000 per house,
residents may reasonably ask how that amount was derived.
Any generator cost used in the estate budget should also feed into how to calculate estate service charge.
Who pays for common-area electricity?
Not all electricity belongs to individual households.
An estate may use power for:
- streetlights;
- gatehouse;
- boom barriers;
- CCTV;
- water pumps;
- security systems;
- clubhouse;
- estate office;
- sewage systems;
- and other shared infrastructure.
That consumption should be identifiable where practical.
Otherwise residents may end up paying household electricity bills that also contain large unexplained common-area loads.
One approach is to meter common infrastructure separately.
Management can then say:
Household electricity consumption:
X units.
Common-area electricity:
Y units.
The common-area portion can be funded according to the estate's approved service-charge allocation.
This also helps management identify abnormal consumption.
If common-area power use suddenly doubles, the estate can investigate:
- faulty equipment;
- pumping problems;
- increased generator hours;
- electrical faults;
- or unauthorised connections.
Common electricity should appear clearly in the estate budget rather than disappearing inside a miscellaneous expense.
What happens when a tenant moves into a property with old electricity debt?
Check before moving in.
NERC specifically advises incoming occupants to find out the electricity billing status of an apartment before renting it.
Where a new occupant discovers an outstanding bill belonging to a previous customer, NERC says the Distribution Company should be notified so the outstanding debt can be assigned to the appropriate customer. (NERC)
The Customer Protection Regulations also provide for a final bill when a customer moves away from a supply address. (NERC)
On move-in, record:
- meter number;
- current meter reading;
- prepaid credit where applicable;
- outstanding DisCo balance;
- generator sub-meter reading;
- and move-in date.
Take photographs where useful.
The same process should happen when someone moves out.
This creates a clear cutoff between the old and new occupant.
Do not make a new tenant inherit an unexplained generator balance simply because management replaced the former resident's name in a spreadsheet.
For other estate charges, see who pays estate dues in Nigeria.
What should estates avoid when managing meters?
Do not tamper with electricity meters.
Do not bypass them.
Do not create unauthorised connections.
NERC's amended order on unauthorised access, meter tampering and bypass took effect on 22 January 2025 and allows DisCos to disconnect unauthorised connections under the applicable regulatory framework. (NERC)
Residents should also avoid opening or modifying DisCo equipment themselves.
If a meter is faulty, report it through the proper electricity provider process.
NERC says customers should report meter bypass and that faulty or obsolete meters are subject to replacement under its metering rules. (NERC)
Estates using private sub-meters for internal generator or bulk-power allocation should also distinguish them clearly from official DisCo meters.
A private sub-meter can help management measure internal consumption.
It does not automatically become the resident's official DisCo meter.
Where an estate is planning a large private electricity distribution, resale or generation arrangement, management should get appropriate technical and regulatory advice rather than assuming normal estate-service rules are enough.
Nigeria's electricity regulation is also increasingly state-specific.
NERC announced in May 2026 that a number of states had moved electricity-market complaint responsibilities to their own state electricity regulators. (NERC)
So the correct regulator for a billing or distribution complaint can now depend on the state.
How should residents see their power charges?
Do not give residents one figure called electricity.
Break it down.
A clear statement might show:
DisCo electricity
Paid directly through prepaid meter.
Generator consumption
N42,000
Common-area power contribution
N10,000
Previous generator balance
N8,000
Payment received
N40,000
Outstanding balance
N20,000
Now the resident knows what they are paying for.
The estate should preserve:
- meter readings;
- billing periods;
- generator operating records;
- diesel purchases;
- payments;
- credits;
- and adjustments.
Receipts should state what was paid.
If a resident pays N50,000 toward generator electricity, the receipt should not simply say estate dues.
Use estate payment receipts and records to preserve the audit trail.
Payments should also be reconciled regularly against the estate bank account through the estate payment reconciliation process.
The more expensive electricity becomes, the more important transparent records become.
How does Kompound help manage estate power payments?
Kompound currently supports household billing, payments, statements and resident wallets. Residents can fund the wallet by card or bank transfer and use it for dues, bills and services. The app also supports the purchase of electricity tokens. (Kompound)
That gives estates a way to keep electricity-related charges visible alongside other household obligations.
For example, after management has calculated an approved generator charge, the resident account can distinguish it from:
- service charge;
- special levy;
- other estate bills;
- and previous balances.
Kompound records every charge and payment, which helps preserve the history through EXCO handovers. (Kompound)
Its current pricing also includes payments, statements and reporting and states that Kompound does not take a percentage of the estate dues collected. (Kompound Pricing)
There is an important limitation.
Kompound's current public product documentation does not advertise automatic generator sub-meter reading or a dedicated generator energy-management system.
That means the estate still needs to obtain the actual consumption figures from its meters or power-management equipment and calculate the approved charges.
Kompound can then handle the household billing, payment and statement side.
That distinction matters.
The software should not invent electricity consumption.
It should preserve the financial record created from a properly managed power system.
The strongest estate power supply in Nigeria setup therefore separates four things:
DisCo electricity
Metered and billed according to the applicable electricity regulatory framework.
Backup generation
Measured and allocated using an agreed estate method.
Common-area electricity
Tracked separately where practical.
Household billing
Clearly recorded so residents know what they owe and why.
Electricity disputes become much easier to prevent when residents can see the meter, see the calculation and see the payment history.
The estate may not be able to control how many hours the public grid supplies.
It can control how transparently the electricity it receives and generates is measured and paid for.
