The ‘smart meters vs regular meters’ was once a genuine debate, but now that has been effectively settled. Regular meters belong to the past. Thanks to advancements made in AMI within the last few years, smart meters have become core to driving a data-driven grid ecosystem.
This has led to an increase in investment in smart metering projects and greater adoption across countries. According to a study by Berg Insight, smart meter adoption in North America has already surpassed 82%. Studies have also shown the installed base of meters in North America is set to increase from 152.4 million in 2024, to 280.9 million in 2030.
The real challenge here is how do utilities choose the right smart metering technology for their grids? Utility leaders need to look beyond just installation figures, and divert attention to cybersecurity, consumer engagement, long-term growth, etc. The blog will discuss what makes smart metering distinct from traditional meters, along with the varying criteria utilities must weigh in to make sure their investments drive tangible outcomes.
What Are Smart Meters?
Smart meters are digital devices designed to replace the traditional metering systems.
Unlike regular meters that only record total consumption, smart meters enable bidirectional or two-way communication flow between the customer and utility. These advanced metering systems do not just provide measure consumption, they also transmit real-time data, opening up possibilities for operational efficiency and improved consumer engagement.
In traditional metering, each utility receives one reading per month. The process requires a field personnel to visit the location, note the consumption manually and send the data back to the utility. This can also lead to delays, along with possible instances of meter tampering. Consumers are only able to view a lump sum bill for their monthly consumption. There is little to no insight that provides visibility into their usage trends or patterns.
Smart meters, on the other hand, record energy consumption more accurately. They measure water, energy or gas consumption in near real-time, and transmit the data back to utility backend systems via secured networks.
Core features of modern smart meters include:
- Interval data sharing every 15-30 minutes, with attached timestamps for detailed consumption analysis
- Frictionless integration with existing utility systems (CRN, GIS, MDM HES), removing data silos
- Remote connect/disconnect capabilities for utilities to manage activation, stoppage or resumption of services
- Outage, tamper and theft detection in the form of alerts by identifying anomalies or abnormal consumption
For modern utility organizations, this leads to better planning, faster incident response capabilities and reduced losses. For end consumers, this would translate to more accurate billing, transparency into usage data, and greater trust in utility services.
Benefits of Smart Meters over Regular Meters
Be it in terms of efficiency or user engagement, smart meters provide a host of benefits to both utility providers and consumers. We have listed some of them below:
Accurate billing
Digital smart meters provide automated readings, updated every 15-30 minutes, depending on the tariff rate that the customer has opted for. The big benefit here is that it helps eliminate estimation from bills, and makes them more accurate. Consumers are now charged exactly for what they use, reducing conflicts and elevating the overall CX.
Theft and tamper detection
Smart metering comes with real-time tamper or theft detection capabilities, helping reduce non-technical losses. Backend personnel in the utility can see if there is a sudden spike in consumption beyond expected thresholds, or a customer profile that is showing zero consumption despite continuous electricity flow. Crews can be dispatched at the earliest to prevent any such instances from turning serious, and reducing overhead costs.
Energy usage control
A standout feature of this technology is the ‘in-house’ device that consumers receive alongside the smart meters. With this monitor, they can view their energy consumption across devices, hours and shift their use to off-peak hours. This not only helps reduce their costs, but also minimizes the strain on the power grid, improving its health and contributing to sustainability initiatives.
Apart from the above points, other benefits of smart meters include:
- Improved energy management with consumers making informed decisions regarding consumption, and potentially reducing their bills
- Seamless integration with renewable energy sources like solar and wind, by providing data to manage distributed assets in an efficient manner
- Support for multiple billing models like ToU (time-of-use), tiered, peak-valley, etc, depending on the unique needs of the customer
Challenges and Risks Associated with Smart Meters
Even with tangible benefits discussed in the previous section, smart metering projects face certain challenges. Beyond operational value, these devices also widens the field for cyber threats, and raises questions about data rights. That being said, these challenges in utility metering need to be viewed as a governance topic, and not an IT roadblock. Below we have listed some of the common challenges that utility boardroom leaders and executives can expect to see.
Data privacy concerns
Beyond general consumption data, smart meters can also reveal other details like appliance usage and consumer behavioral patterns. Governance bodies like the European Commission have already laid out terms to protect personal data processed and shared by smart meters.
- This includes developing data protection and information security features within smart metering systems before roll-outs.
- Their report also specifies implementing mechanisms to ensure that personal data are stored only for a specific purpose, and for a fixed duration.
It is imperative for utility providers to strictly follow privacy laws and protocols that dictate how consumer data is handled, stored and shared. These regulations may vary, across countries or even regions-wise. But, the goal should always be maintaining transparency in data usage policies, which in turn improves consumer trust.
Cybersecurity threats
Smart meters promise an interconnected grid, allowing utilities to manage consumer usage data in real-time and bring greater transparency in billing. Unfortunately, the features that make smart meters an advantageous alternative to regular meters also make them vulnerable to hackers and cyber-criminals.
- IEEE research indicates that improvements made in power grids introduce new dimensions for cyber attacks. As per the study, more smart meter deployments at the distribution level likely means increased frequency of cyber attacks. Smart meters are not completely free from this threat if the hacker gains access to smart meter password, ID, and other details like communication protocols or built-in software programming.
- Another study by IEA highlights how every component within smart grids, from digital devices, sensors, telecommunication software and equipment, introduces an additional point of vulnerability. There has been an alarming increase in cyber-attacks in electric utilities since 2018, with the incidents reaching an all time high in 2022.
Apart from concerns around data privacy and cybersecurity, other key challenges in smart metering include:
- Many utilities still operate with a hybrid ecosystem, where both IT/OT components work together. Proprietary device stacks such as for systems like MDMS or HES, or vendor lock-in issues can slow down projects and also increase overhead costs.
- Possible health issues arising out of low-level radio frequency EME (electromagnetic energy), which is emitted by smart meters when transmitting data to the utility. However, there has been scientific evidence or proven research to back up these claims.
- Unreliable network connectivity, which still persists in many rural areas. In these regions, smart metering capabilities of real-time data transmission are not often realized, hampering overall system performance.
Despite these hurdles, it is no secret that smart meters surpass regular meters in many critical aspects, from functionality, operational transparency to performance optimization. In the next section, we will explore what makes smart meters distinct from your regular meters.
