In industry, intelligent measurement systems – often referred to as „Smart Meter“ or „Smart Metering“ is standard – and has been for a long time. They are the basis for transparent billing, load control, energy efficiency, and grid integration of decentralized generation. In Germany, they are mandatory by law for many companies or will soon be required by law, especially for larger consumers and plant operators.
In this post, we explain,
- what is understood by „Smart Meter“ or „Smart Metering“ in the industry,
- What role do RLM meters and voltage quality analyzers play here?,
- What advantages they bring to businesses
- and how industrial companies should prepare technically for it.
In industry, a „smart meter“ refers to an advanced digital meter that records electricity consumption in detail. This data is then transmitted to the energy supplier and can also be accessed by the industrial consumer. Smart meters offer a more precise understanding of energy usage compared to traditional analog meters.
The term „smart meter“ was originally coined for smaller consumers and households, but is also frequently used in commercial and industrial practice as an umbrella term for Intelligent measurement and control systems used.
In industry, „smart metering“ usually includes:
- Registering power measurement and load profile meters (RLM meters).
- Voltage Quality Analyzers.
- Communication units (e.g., Smart Meter Gateways, PLC modules, radio interfaces).
Together, these components form a system that:
- records energy consumption in real time,
- documented the load profiles and peak loads,
- Transmits data to the grid operator, measurement partners, and market partners
- and serves as the basis for energy management and control functions.
Why is smart metering considered standard in industry?
In industry, smart meter-based systems are standard in several respects:
- RLM obligation
Companies with an annual consumption of 100,000 kWh or more, or with larger feed-in systems, are obliged to, recording load profile meter to use. These measure consumption every quarter of an hour and provide the basis for load profiles and accurate billing. - RLM for larger PV systems
Commercial PV systems from 100 kWp are typically also equipped with RLM meters to make feed-in and load profiles transparent for direct marketing and grid integration. - RLM for Energy Efficiency and Reporting
RLM data are the basis for energy audits, sustainability reports, ESRS/CSRD reporting, and energy efficiency measures, as they provide actual load profile data. - Smart Meter Act (GNDEW)
With the Act on the Digitalization of the Energy Transition (GNDEW), the use of intelligent metering systems is becoming mandatory for more and more companies, including smaller businesses with 6,000–100,000 kWh/year.
For industry, this means: „Smart Metering“ is not just a trend, but a technical and legal requirement for grid, market, and efficiency control.
What components are part of an industrial smart meter system?
In industry, three components are typically combined:
1. RLM meter (load profile meter)
- Measure consumption or feed-in Quarter-hourly.
- Create detailed load profiles and peak loads.
- Serve as the basis for billing, grid fee models, and energy efficiency measures.
- Are installed by the grid operator and are generally mandatory from 100,000 kWh/year.
2. Power Quality Analyzers
- Monitor voltage, current, frequency, harmonics, flicker, and other electrical parameters.
- Capture network irregularities and disruptions.
- Control switching operations, implement protection and regulation functions.
- Are often the central control and monitoring unit in energy management.
3. Communication and Gateway Units
- Connect RLM meters, voltage quality analyzers, and energy management software.
- Send data to grid operators, metering point operators, financiers, or energy management platforms.
- Enable automated processes, reporting, and control.
Together, they form a complete, industrial-grade smart meter system that makes energy flow visible, controllable, and documentable.
What are the benefits of smart metering for businesses?
A modern smart meter system offers businesses several practical advantages:
- Transparent billing and grid fees
RLM data allows precise recognition of peak loads and smoothing of load profiles.Peak ShavingThis allows for optimized grid fees and reduced energy costs. - Identification of savings potential
The load profile can be analyzed to identify inefficient consumption patterns and implement energy efficiency measures. - Real-time monitoring and control
Smart meter-based systems provide real-time data on consumption, feed-in, voltage quality, and system operating status. - Integration of decentralized generation
For PV systems, Large-scale battery storage and Charging infrastructure The meters provide the basic data for direct marketing, feed-in management, and grid integration. - Energy Efficiency, Audits, and ESG Reporting
Last and measurement data serve as the basis for Energy audits, energy efficiency measures and for reports regarding Sustainability and ESG. - Network and system stability
Voltage quality analyzers detect disturbances, overloads, and harmonics early on, protecting plants and equipment.
How is the technical implementation carried out in practice?
Installing a smart meter system in industry involves several steps:
- Correct Component Selection
Selection of suitable RLM meters, voltage quality analyzers, and communication modules, matching the system size, grid technology, and market role. - AC-side assembly
RLM meters and voltage quality analyzers are typically installed on the AC side of the company or plant grid, close to the grid connection point. - Communication technology
When installed, communication modules (e.g., GSM, GPRS, PLC, radio) are integrated to transmit data to network operators, measurement partners, and market partners. - Software integration
The data is transmitted to an energy management system, cloud platform, or monitoring tool to enable real-time analysis, reporting, and control. - Registration and Approval
The plant must be registered with the grid operator, metering point operator, and, if applicable, the financier or insurers, and must meet the technical specifications.
What does this mean for the energy transition and industry?
Smart meter systems are a central component of the energy transition, particularly for industry:
- Grid flexibility
Through Load shifting, Demand-response and flexible operational management can help companies smooth out peak loads, reduce grid charges, and stabilize the grid. - Integration of renewable energies
For PV systems, storage systems, heat pumps, and charging infrastructure, smart meter systems provide the data necessary for control, direct marketing, and grid integration. - Energy Efficiency and Sustainability
Transparent load profiles and energy monitoring promote efficiency measures and ESG goals. - Digitalization
Smart measurement and control functions form the foundation of the digital energy sector, energy management, and sustainable operational processes.
Frequently Asked Questions
What is the difference between an RLM meter and a smart meter?
An RLM meter is a special load profiler that records consumption every fifteen minutes.
A smart meter is a general term for an intelligent measurement and control system that includes RLM meters, communication units, and, if necessary, voltage quality analyzers.
Which companies are RLM-obligated?
Companies with an annual consumption of 100,000 kWh or more, or larger feed-in facilities, are generally required to use RLM meters. The exact rules depend on the grid zone and the type of facility.
Does every company need a smart meter?
In industry, smart meter-based systems are mandatory or will soon be required for large consumers. For smaller businesses, installation is planned for consumption above 6,000 kWh/year and PV systems greater than 7 kWp.
What does a power quality analyzer do?
It monitors voltage, current, frequency, harmonics, flicker, and other electrical parameters to detect irregularities, ensure grid quality, and enable protection and control functions.
