A Comparison of Traditional Metering vs. Smart Metering

The way we consume and manage energy is becoming increasingly crucial as we strive for a more sustainable and energy-efficient future. Smart metering, which allows more precise and real-time monitoring of energy consumption, is one of the most significant technological breakthroughs in this sector. The expansion and development of smart metering are progressing unstoppably, however, there are some open questions around this topic that should be clarified:But what is smart metering? What are its advantages over traditional metering?What types of potential security risks are smart meters exposed to? How can manufacturers prevent them?Keep reading for the answers.

What is Smart Metering?

Smart metering is a technical improvement that is transforming how utility providers and consumers monitor and control energy use in both our businesses and homes. Smart meters – opposed to standard meters that need human reading and computation-, employ innovative technology to gather and communicate real-time data on energy consumption. This information may then be utilized to improve energy efficiency, minimize waste, and, eventually, decrease our energy costs. 

Furthermore, smart meters allow electricity suppliers to better monitor and regulate demand, enhancing grid dependability and stability.

The Key Differences Between Smart Metering and Traditional Metering

When comparing smart metering and traditional metering, the advantages of the former become clear. Let’s see what these are.


Smart meters give more precise and trustworthy data on energy use than manual reading, ensuring that customers are only charged for what they use.

Data Collection and Analysis

Smart meters provide automatic and real-time data on energy consumption, enabling users to keep track of their usage and make better energy-related decisions. Traditional meters require manual reading and are unable to offer such complex databases, as well as analysis and comparison possibilities.


Smart meters are more expensive to install than regular meters, but the long-term advantages outweigh the expenses. They do not require human resources, hence overall operational expenses will be reduced.

Two-Way Communication

Smart meters allow for two-way communication between the meter and the utility, enabling dynamic pricing, demand response programs, and better grid management. Conventional meters do not offer any of these options.

Environmental Impact

Smart meters collect information that may be used to detect areas of energy waste, allowing users to make adjustments that lower their overall energy consumption.

Improved grid stability

Smart meters enable energy suppliers to better understand and control demand, which helps them to maintain a stable and dependable electricity infrastructure.

Comparing Security Aspects of Traditional and Smart Metering

Security is definitely a priority for both standard and smart metering systems. The nature of security risks and methods for avoiding them, however, varies across the two systems.

Traditional Metering

Traditional energy metering systems have been around for many years. They have been relatively reliable, but it doesn’t mean that they would not pose certain security risks. The most common of these are tampering, theft, and unauthorized access, in which cases a traditional metering device is not sending any alarm to the utility provider. Another security issue associated with traditional energy metering is the possibility of data breaches. Conventional meters are based on manual data collection and storage, which is susceptible to human mistakes and data loss.

Smart Metering

As we incorporate increasingly complex technology into our daily lives, it is critical to address the security implications of these advances. Smart metering has given several benefits in the energy sector, including enhanced efficiency and cost reductions. Yet, just like any technology, it carries potential security threats.

Although smart metering systems are provided with advanced security features, the devices, and the users are still vulnerable to numerous risks:

  • Hacking: Since smart meters are network-connected, they may be subject to cyber-attacks that allow unauthorized access to the meter or the energy infrastructure. Hackers can possibly modify meter data or get access to other devices on the same network, opening the door to more attacks.
  • Spying: Data from smart meters might be exploited for spying or other criminal reasons. Since smart meters capture extensive data on energy consumption, they might be used to monitor customer behavior or follow people’s actions in their homes or companies.
  • Phishing Scams: Attackers may employ phishing schemes to deceive smart metering users into disclosing sensitive information, such as login passwords or financial data.
  • Connected Smart Home Devices: Smart meters may be connected to other insecure smart home devices, such as smart thermostats or plugs, that are vulnerable to hacking. 
  • Physical Risks: Smart metering devices might be accessed by unauthorized persons, which could allow malicious actors to tamper with the meter, perhaps resulting in false energy use readings or even causing the meter to malfunction. In most cases a certified intelligent measuring device will send an automatic alarm to the head-end-system, which is already a big advantage compared to the traditional devices.

What measures can be taken to enhance the security of smart metering?

To be successful in the market, smart meter manufacturers must assure both precise data gathering and secure data transfer. The security of an intelligent metering device or system can be increased even before it is placed on the market by assessing it against the appropriate international security standard(s): 

Common Criteria (CC) 

Common Criteria is an international standard for evaluating and certifying the security of IT products. There is a dedicated Protection Profile for smart metering devices’ Common Criteria certification. 

The Swiss example – METAS

The METAS certification is required for smart meters to be used in Switzerland and gives consumers assurance that their energy use is being correctly tracked and securely measured by certified intelligent measuring devices.

IEC 62443 

ISA/IEC 62443 is a collection of international standards for the security of industrial automation and control systems (IACS). The standards establish a set of frameworks and guidelines for designing, deploying, and maintaining secure IACS systems. It covers risk assessment, security policy, network security, system hardening, secure remote access, incident response, and security management.

Radio Equipment Directive

Organizations in the energy industry are subject to the EU’s Radio Equipment Directive 2014/53/EU (RED), which they must follow and verify they have met their obligations under the directive.

Smart metering devices or systems that comply with the specific requirements based on the evaluation of an independent, competent, and accredited cybersecurity laboratory will receive the given security certification, which provides them with numerous benefits.


Overall, smart metering outperforms traditional metering in terms of accuracy, efficiency, and flexibility, as well as enhanced energy management and system stability. However, it is also important to keep in mind the new potential security risks associated with the expansion of this innovative technology. 

Those manufacturers that conform their products to the appropriate international security standard can help reduce these risks in addition to becoming more competitive and credible on the market.
