What Is a Smart Electricity Meter and How Does It Work?
What is a smart electricity meter and how is it different from an old meter? A simple guide to how it works, how to read it, prepaid meters, and the benefits.
Across the Middle East and much of the world, electricity companies are replacing old spinning-disc meters with digital ones, and many people are asking the same question: what is a smart electricity meter, how does it work, and will it change my bill? Here is a simple guide to everything you need to know.
What is a smart electricity meter?
A smart electricity meter is an electronic device that measures how much electricity a home or shop uses and sends the readings automatically to the electricity company over a communications network. Nobody needs to visit your home to read it.
Old mechanical meters work differently: a metal disc spins faster as you use more power, and someone has to read the numbers by hand every month.
| Comparison | Old meter | Smart meter |
|---|---|---|
| How it measures | Spinning disc and mechanical dials | Electronic circuits and a digital display |
| Reading | Manual, by a meter reader | Automatic and remote |
| Usage detail | One running total | Detailed usage at short intervals |
| Disconnect and reconnect | Manual, on site | Can be done remotely |
How does a smart meter work?
A smart meter works in three simple steps:
- Measuring: it continuously measures voltage and current and calculates the energy used in kilowatt-hours (kWh).
- Recording: it stores consumption at regular intervals, so it knows when you used electricity, not just how much.
- Sending: it transmits the data to the company’s systems by radio, mobile networks or even the power lines themselves, a setup known as advanced metering infrastructure (AMI).
Because the link is two-way, the company can also send commands to the meter, such as updating the tariff or switching the supply off and on.
Smart meters in the Arab world
- Saudi Arabia: in April 2021 the Saudi Electricity Company announced that it had installed or replaced more than 10 million smart meters across the Kingdom, at no cost to customers.
- Jordan: figures from the Jordan Electric Power Company (JEPCO) in 2026 show about 1.56 million smart meters installed, close to 95% of the subscriptions in its service area, and other distribution companies run similar projects.
Did you know? Saudi Arabia’s smart meter project, covering more than 10 million meters, took only about 13 months, finishing well ahead of its planned 2023 deadline. Around 4 million of the meters were made locally.
How to read a smart electricity meter
Displays vary by manufacturer, but the basics are the same:
- The screen shows several readings that cycle automatically every few seconds, or when you press the meter’s button.
- Look for the number labelled kWh. That is the cumulative reading, your total consumption since the meter was installed.
- To find your monthly use, note the reading on a given day and subtract it from the reading on the same day the following month.
- On prepaid meters, the screen also shows your remaining credit.
If you can’t make sense of the codes on your meter, check your electricity company’s guide or official app. Many companies offer apps that show daily usage.
What is a prepaid electricity meter?
With a prepaid meter you top up credit in advance, much like a mobile phone, and the balance falls as you use power. When it runs out, the meter cuts the supply automatically until you top up again. This helps with budgeting and avoids surprise bills. Not every prepaid meter is smart, though: some are topped up with a card or a typed code and have no network connection.
Benefits for consumers
- Accurate bills based on actual readings rather than estimates.
- Daily usage tracking, so you can spot the appliances that push your bill up.
- Faster detection of faults and power cuts.
- Time-of-use tariffs in the future, letting you pay less by running some appliances outside peak hours.

Frequently asked questions
Does a smart meter increase my electricity bill?
A smart meter doesn’t increase your consumption; it measures it more accurately. Some customers notice a higher bill after installation because the old meter was less accurate or bills were estimated. If you doubt a reading, you can ask your electricity company to test the meter.
Are smart meter radio waves harmful?
Smart meters transmit low-power radio signals in short bursts. Regulators say they fall within international exposure limits, and the exposure is far lower than from a mobile phone held to your ear.
Can a smart meter be tampered with?
Smart meters alert the company when someone tries to open or interfere with them. Tampering with a meter is also illegal and dangerous.
Key takeaway
A smart electricity meter is a digital device that measures your consumption and sends it automatically to your electricity company. It ends manual readings, gives you more accurate bills and helps you track your usage. Read the figure marked kWh to see your consumption, and use your meter’s data to save electricity and lower your bill.
