Smart Meter Myths vs Facts: What Electricity Consumers Need to Know
Published on 21 August 2026
Smart meters are becoming an increasingly common part of India’s electricity infrastructure. As more households, shops and businesses move from traditional meters to smart meters, questions about electricity bills, safety, privacy, prepaid metering and power supply are also increasing. Some concerns come from genuine questions. Others are based on social media posts, word of mouth or misunderstandings about how smart meters work. So, what is actually true? This guide answers the most common questions about smart meters and separates smart meter myths from facts in simple terms.
Smart Meter Myths vs Facts
Myth 1: Do smart meters increase electricity bills?
Fact: No. A smart meter does not increase your electricity tariff or decide how much you are charged. It measures your electricity consumption, while your bill is calculated using your applicable tariff and billing rules.
A change in your bill after a smart meter is installed does not necessarily mean that the meter is charging you more. Your bill can change because of higher electricity consumption, a change in tariff, correction of previous estimated readings, billing-cycle differences or other applicable charges.
A smart meter records electricity consumption electronically and communicates the meter data to the electricity distribution company. This reduces dependence on manual meter readings and estimated consumption.
In simple terms: the meter measures your consumption; the applicable tariff determines what you pay.
Myth 2: Does a Smart Meter Use Electricity and Increase My Bill?
Fact: Yes, a smart meter consumes a small amount of electricity to operate, but the cost of this electricity is borne by the utility and is not added to the consumer’s electricity bill.
Like other electronic devices, a smart meter requires power to operate its display, measurement circuitry, clock and communication functions.
However, the electricity consumed by the smart meter is not charged as part of the consumer’s electricity consumption. The cost of operating the meter is borne by the electricity utility.

Myth 3: Are smart meters safe?
Fact: Yes. Smart meters supplied in India are required to meet applicable safety, performance and conformity requirements.
Smart meters undergo specified testing for parameters such as electrical safety, measurement performance, environmental conditions and electromagnetic compatibility.
In India, IS 16444 specifies requirements for smart meters. The Smart Meters (Quality Control) Order, 2023 requires covered smart meters to conform to the applicable Indian Standard and bear the BIS Standard Mark under the applicable certification scheme. Smart-meter specifications issued by the Central Electricity Authority (CEA) also include requirements related to measurement, communication, tamper-event detection, power-event alarms and other functions.
Myth 4: Are Smart Meters Harmful to Health?
Fact: No. Smart meters use the same type of radio-frequency waves used by everyday wireless technologies, including Wi-Fi routers, mobile phones and Bluetooth devices.
Smart meters communicate wirelessly by using radio-frequency (RF) signals to send electricity consumption data to the electricity distribution system. Like Wi-Fi routers, they use RF technology for communication. However, the exact frequency and communication technology used can vary depending on the smart-meter deployment.
In India, smart meters can use RF Mesh or cellular communication technologies. Kimbal’s smart meters, for example, support RF Mesh and cellular communication depending on the deployment requirements.
Myth 5: Do smart meters invade my privacy?
Fact: Smart meters collect electricity consumption data, so data privacy is an important consideration, but the meter does not record conversations, images or activities inside your home.
A smart meter records information related to electricity consumption, such as how much electricity is used and, depending on the system configuration, when it is used. This information helps the electricity distribution company with functions such as:
- Meter reading and billing
- Consumption monitoring
- Energy accounting
- Outage management
- Demand analysis
- Detection of unusual consumption or tampering
If you have questions about your data, check your DISCOM’s policy to understand what information is collected, why it is collected, how it is used and who can access it.
Myth 6: Can smart meters be hacked easily?
Fact: Smart-meter systems use multiple security measures to protect meter data and communications, so hacking a smart meter is not as simple as connecting to a home Wi-Fi network.
Depending on the system, security measures can include:
- Encryption: Helps protect data during communication.
- Authentication: Helps ensure that only authorised devices or systems can communicate with the meter.
- Access controls: Restrict who can access meter data and system functions.
- Secure communication networks: Smart meters communicate through the communication infrastructure designed for the AMI system rather than simply using the consumer’s home Wi-Fi.
- Security updates: Where supported, smart-meter systems can receive remote firmware or software updates.
No connected technology can honestly be described as completely immune to cyber threats. The important point is that smart-meter systems are designed with security controls to reduce the risk of unauthorised access and data manipulation.

Myth 7: Do smart meters stop working during a power cut?
Fact: A smart meter cannot continue normal measurement and communication without power, but many smart-meter systems can help the electricity distribution company detect outages automatically.
Depending on the meter and communication system, a smart meter may send a last-gasp message when it detects a loss of supply. When communication is restored after power returns, the meter can also communicate again with the utility system. This information can help the electricity distribution company identify the location and timing of outages and improve restoration efforts.
Myth 8: Can a smart meter disconnect my electricity automatically?
Fact: A smart meter does not independently decide to disconnect your electricity, although some smart meters can support remote connect or disconnect functions when authorised by the electricity distribution company.
Some smart-meter specifications include an integrated load-limiting switch or relay and support remote control functions. Whether and how such a function is used depends on the meter, the utility’s system and the applicable rules and consumer arrangement.
The important distinction is this: The smart meter executes an authorised function. It does not independently decide that your electricity should be disconnected.
Myth 9: Are smart meters and prepaid meters the same?
Fact: No. Smart metering and prepaid metering refer to different things.
A smart meter describes the meter’s measurement, communication and other smart capabilities. Prepaid metering describes a billing arrangement in which consumers pay or recharge before consuming electricity, subject to the applicable rules.
A smart meter can support prepaid functionality, but a smart meter and a prepaid meter are not interchangeable terms. This distinction is particularly important in India because the country’s smart-metering programme includes prepaid smart-metering as a major component. The RDSS framework envisages prepaid smart metering alongside broader distribution-system modernisation.

Under RDSS, smart-metering works have been sanctioned across 45 distribution utilities in 28 States and Union Territories, covering nearly 20 crore consumers, along with distribution-transformer and feeder metering. The actual rollout schedule varies between states, DISCOMs and projects. This means a consumer’s location and local rollout plan determine when a smart meter is installed.
Myth 12: Do smart meters need frequent maintenance?
Fact: No. Smart meters are designed for long-term operation and can support remote monitoring and diagnostics, reducing the need for routine physical visits.
Smart-meter systems can monitor meter performance and identify certain faults or abnormal conditions remotely. Depending on the meter and system, software or firmware updates can also be carried out remotely. Central Electricity Authority (CEA) smart-meter specifications include remote firmware upgrade as a functional requirement. Physical maintenance may still be required if a meter develops a fault or needs to be inspected or replaced.
Myth 13: Can a smart meter give incorrect readings?
Fact: Like any measuring device, a smart meter must meet specified accuracy requirements, but no meter should be assumed to be completely immune to faults.
Smart meters supplied in India are required to meet applicable standards and testing requirements for measurement accuracy and other performance parameters. IS 16444 includes requirements relating to smart-meter measurement and functional performance.
If you believe your meter reading or electricity bill is incorrect, contact your DISCOM and follow the applicable meter-testing and consumer grievance process. Dial 1912 to reach the national toll-free electricity helpline used across India to report power outages, transformer faults, billing errors, and emergency electrical hazards to your local power distribution company.
How Does a Smart Meter Work?

How Does a Smart Meter Measure Electricity?
A smart meter measures electrical parameters such as voltage and current to calculate electricity consumption, which is recorded in kilowatt-hours (kWh). Here’s the basic relationship:
Voltage + Current → Power → Energy Consumption → kWh
- Voltage – The electrical potential that drives current through an electrical circuit.
- Current – The flow of electric charge through the circuit. The amount of current changes depending on the electrical load being used.
- Power – Indicates the rate at which electrical energy is being used. It is measured in watts (W) or kilowatts (kW).
- kilowatt-hour – A kilowatt-hour (kWh) is a unit of electrical energy.
For example, if a 1,000-watt appliance operates for one hour: 1,000 watts × 1 hour = 1 kWh. Your electricity bill is based on the amount of electrical energy consumed, measured in kWh or units.
