In an economic landscape marked by volatile electricity prices and the climate emergency, energy management has become a top-level management issue. Yet, many companies are still operating without a clear plan, simply accepting the overall bill without understanding the underlying mechanisms. Energy metering is now essential for any organization wishing to regain control over its expenses and carbon footprint. At Powesco, we believe that measuring is the first step to saving.
What is energy metering?
Energy metering is not simply about having a meter at the property line. It is a ecosystem that aims to map, with surgical precision, the consumption of all fluids within a building or industrial site: electricity, gas, water, but also steam or heating calories.
How does it work in practice?
The process is based on a three-step data architecture
- It all starts with capture, where measuring instruments (sub-counters, measuring units) record the physical flows.
- This information is then transmitted via communication networks, whether wired (Modbus, M-Bus) or wireless (IoT technologies such as LoRaWAN), to a centralized interface.
- Finally comes the crucial analysis : the raw data is transformed into energy performance indicators (EPIs), allowing consumption to be correlated to a specific activity, an outside temperature or a production volume.
Why has energy metering become a strategic imperative?
Far from being a simple technical option, the deployment of a counting system addresses four major challenges for the modern company.
A response to increasing regulatory requirements
The French and European legislative framework has become considerably stricter, transforming sobriety into a legal obligation:
- Construction standards : From RT2012 to RE2020, the obligation to sectorize consumption by item (heating, lighting, power outlets) has become the norm.
- Performance management : The ISO 50001 standard requires a rigorous energy review, which is impossible to achieve without a reliable metering plan. Furthermore, IEC 60364-8-1 provides guidelines for optimizing electrical installations for maximum energy efficiency
- Key decrees : The Tertiary Decree mandates drastic reductions in energy consumption (-40% by 2030), while the BACS Decree requires tertiary buildings to be equipped with automation systems. Finally, the DDADUE law strengthens transparency and auditing for large organizations, making metering the sole arbiter of compliance.
A lever for financial competitiveness
In an uninstrumented system, energy is a "black box." Metering allows you to open this box and identify potential savings. By isolating the costs related to heating, air conditioning, industrial processes, or lighting, you can detect anomalies (nighttime consumption spikes, incorrect settings) and reduce your bills without significant investment, simply through operational optimization.
Attractiveness and social responsibility (CSR)
The building reflects a company's commitment. A high-performance metering system ensures comfort for employees, reducing absenteeism and boosting productivity. It also provides tangible proof of your CSR to your clients, investors, and future talent, who are increasingly sensitive to transparent carbon footprints.
Operational safety and maintenance
Real-time monitoring of load curves allows for the detection of anomalies and deviations before they become critical. A sudden surge in power consumption on a motor can signal an failure . Load monitoring then becomes a maintenance , preventing costly production shutdowns and ensuring the safety of equipment and personnel.
Energy metering: which companies are affected?
Each sector has its own characteristics that counting helps to control:
Tertiary
For offices and shops, the challenge lies in managing intermittency (occupancy vs. vacancy) and optimizing comfort.
Industry
Here, we seek to calculate the energy intensity per unit produced in order to refine the cost price and optimize thermal or mechanical processes
Health
Hospitals and clinics must reconcile continuity of service with cost control in high-consumption areas (operating rooms, imaging).
Communities
Managing public assets requires a consolidated vision to prioritize renovation energy work on the most energy-intensive buildings.
What technical solutions are available on the market?
The technological offering has diversified to adapt to all infrastructure configurations.
From the traditional meter to the smart manager
Solutions like those offered by Hager allow for the integration of metering directly into the electrical panel. Several approaches exist:
- Direct metering : Ideal for small circuits where the current flows through the device.
- Indirect metering : Uses current transformers (CTs) to measure high power without interrupting service.
- Integrated metering : Native integration into circuit breakers for maximum compactness.
Submetering and communication systems
Sub-metering allows for a fine level of granularity (by machine, by floor, or by usage). But the real value lies in the software intelligence:
- BMS (Building Management System): To actively control equipment based on consumption thresholds.
- EMS (Energy Management System) : These specialized platforms collect multi-site data, generate alerts and produce regulatory reports automatically.

FAQ
What is a "Smart" or IoT energy monitoring system?
An intelligent and advanced system goes beyond simple physical measurement. Thanks to IoT and wireless or wired communication, consumption data (electricity, natural gas, water, thermal energy) is transmitted in real time to a software platform (SEME). This monitoring allows you to analyze energy consumption via key performance indicators (KPIs) and proactively manage your energy strategy.
How to integrate the monitoring of water and thermal energy meters?
An effective energy metering plan doesn't stop at electricity. For comprehensive energy management, it's crucial to include water (cold and hot water) as well as heat meters for district heating networks. These metering devices often use specific communication protocols (M-Bus or IoT). By centralizing these data flows, you can identify leaks or boiler efficiency deviations, thus optimizing the building's overall energy performance.
Can energy metering be combined with a solar installation?
Absolutely. It's actually an excellent starting point for the energy transition. By installing meters at your solar production, you can analyze your self-consumption and adjust your usage to consume energy when it's produced. This improves overall energy efficiency and further reduces your greenhouse gas emissions.
