An advanced technology called a smart metering system measures and monitors electricity, gas, or water consumption in almost real-time.
In different parts of the world, people interchangeably use the terms “smart metering system” or “advanced metering infrastructure” (AMI). Both terms denote a next-generation energy management system consisting of a smart meter, data management platform, and communication networks that enable two-way communication.
Smart meter: Unlike mechanical meters, which require manual reading by utility personnel, smart meters automatically collect data and transmit it remotely to the network server. Ultrasonic meters provide highly accurate measurements of resource usage, leading to transparent billing. The installation of smart meters saves significant costs for utilities and submetering companies, as meters automatically send data to the data management platform, resulting in savings on transportation, fuel, insurance, and labor expenses.
Network: A wireless network transfers communication from the smart meter to the utility’s server, where it stores and analyzes data. Low Power Wide Area Networks (LPWAN), such as LoRaWAN, NB-IoT, Mioty, and LTE, can transmit packets of data over long distances while utilizing low power consumption. Today, smart metering systems widely adopt LPWAN technology because of its robust infrastructure, long battery life, and low latency. Each communication technology differs in several key factors: coverage, range, scalability, security, compliance, power consumption, data transmission speed, and cost.
Network monitoring: This component helps to ensure stable smart metering data transmission. It involves monitoring data telegrams, network redundancy, and stability. The key benefit of network monitoring functionality is to monitor the active network health, identify and resolve connectivity issues, and provide insights about problematic network areas to proactively address them, thereby preventing possible data loss.
Data management platform: Smart metering software typically integrates both MDM (meter data management) and HES (head-end system) functionalities into a single platform. It receives data from the communication network and smart meters, efficiently storing, analyzing, monitoring, and processing the data for various applications. Third-party integrations via API facilitate data usage, such as providing billing services to clients.
Remote Data Monitoring: Smart meters enable utility companies to monitor consumption patterns remotely, eliminating the need for manual meter readings.
Almost Real-Time Data: These systems provide almost real-time information on energy or water usage, allowing consumers and utility companies to accurately track consumption patterns.
Two-way Communication: Smart meters can communicate data to the utility provider and receive commands.
Network Monitoring: This involves the ability to view all incoming raw data telegrams, analysing network stability based on signal health parameters, ensuring well-planned network coverage, and maintaining a constant flow of data telegrams from devices.
Improved Efficiency: By providing accurate and timely information, smart metering systems help identify areas of abnormal resource consumption, leaks, bursts, and backflow. This allows for more efficient resource use and reduced waste, as well as the detection of faulty installations.
Smart metering systems or advanced metering infrastructure leverage advanced technology to measure, monitor, and manage the consumption of electricity, gas, or water. Here’s how the system typically operates:
Prepared Infrastructure: Install smart meters at selected locations, ensuring their activation, and prepare the network deployment to receive data.
Data Collection: Smart meters are equipped with sensors that measure resource (electricity, gas, or water) consumption in almost real-time or at regular intervals.
Data Transmission: The meter collects consumption data and communicates it using various communication technologies (for example, through a gateway if using LoRaWAN or through a communication tower if using NB-IoT). This data transmission can be to a central server managed by the utility company.
Remote Monitoring: Utility companies can remotely access consumption data collected by smart meters, eliminating the need for manual readings and enabling efficient monitoring of usage patterns. Water leaks, bursts, and freezes are also immediately detected, and alerts are sent to the responsible party.
Two-way Communication: Many smart meters support two-way communication, allowing the utility company not just to receive data from the meter but also to send commands or updates to the meter.
Data Analysis and Management: Consumption data collected by smart meters is analyzed to identify usage patterns, trends, and abnormalities, helping utility companies optimize operations, manage demand more effectively, and identify efficiency improvement opportunities.
Billing Management: Smart metering systems ensure easy and transparent billing for consumers, facilitating operational processes for utility and submetering companies.
Integration with Other Platforms: Integrate data management platforms with third-party systems such as Business Intelligence, Billing Services, Mobile apps for consumers to follow consumption data, or other applications to facilitate daily tasks.
Smart metering systems provide companies with a wealth of analyzed information in the data management platform. The specific data available depends on the managed resource (gas, electricity, or water). Key information includes resource consumption, consumption predictions, critical alerts such as leaks, bursts, freezes, low battery indications, maintenance alerts, data outage detection, network health monitoring, and customizable alerts.
Overall, smart metering systems or advanced metering infrastructure offer numerous benefits for both consumers and utility providers. The insights provided by smart metering systems enhance operational efficiency for utility and submetering companies, leading to lower utility capital expenditure and improved environmental sustainability. For consumers, it provides awareness and control over daily resource consumption and ensures transparent invoicing.
