An energy monitoring system collects electrical data from meters installed across a facility and makes that information available for analysis. It can show how much energy is being used, where it is being consumed, when peak demand occurs, and how consumption changes over time.
Modern energy monitoring systems combine meters, communications and software to provide both real-time electrical information and historical consumption data for energy management, cost control and operational analysis.
What Does an Energy Monitoring System Measure?
- Active and reactive energy
- Voltage and current
- Active, reactive and apparent power
- Demand
- Power factor
- Frequency
- Load profiles and consumption trends
- Additional power-quality parameters where supported by the selected meter
How Does an Energy Monitoring System Work?
A typical system has four layers: meters and sensors measure electrical parameters; communications collect the data; software stores and displays it; and users analyze the results to identify trends, abnormal consumption and opportunities for improvement.
| Layer | Function |
|---|---|
| Measure | Power and energy meters collect electrical data at selected measurement points. |
| Communicate | Ethernet, RS-485 and other supported communications transfer the data to local or central systems. |
| Analyze | Energy-management, BMS or SCADA software displays real-time values, trends, reports and alarms. |
| Act | Users identify waste, abnormal loads, peak-demand issues and verify the effect of energy-saving actions. |
Where Can Energy Be Monitored?
- Main incomer
- Distribution boards
- Individual feeders
- Floors or departments
- Tenants
- HVAC / chillers
- Production lines
- Equipment groups or individual loads
Energy Monitoring vs Power Monitoring
Energy monitoring focuses mainly on accumulated consumption and consumption trends over time, such as kWh, demand profiles, allocation and cost. Power monitoring focuses more on instantaneous electrical operating conditions such as voltage, current, kW, kvar, kVA, frequency and power factor. Many modern SATEC meters provide both functions.
| Topic | Energy monitoring | Power monitoring |
|---|---|---|
| Main focus | Consumption over time, allocation, cost and efficiency | Electrical operating conditions and system loading |
| Typical values | kWh, kvarh, demand trends, load profiles | V, A, kW, kvar, kVA, PF, Hz, demand |
| Typical use | Energy management, cost allocation, tenant/department analysis | Electrical operation, loading, alarms and system performance |
How Energy Monitoring Can Reduce Energy Costs
- Identify after-hours or unnecessary loads
- Detect unusual consumption patterns
- Compare departments, buildings or production areas
- Track and manage peak demand
- Monitor power factor and other electrical conditions that can affect operating cost
- Verify the effect of efficiency projects before and after implementation
Applications by Segment
- Industrial facilities – production lines, feeders, HVAC and plant-wide energy use
- Commercial buildings – floors, tenants, HVAC and common services
- Data centers – incomers, UPS/PDU distribution, branch circuits and tenant/customer allocation
- Campuses and public facilities – buildings, departments and central utilities
- Renewable / BESS sites – import/export, auxiliary loads and system-level energy flows where applicable
SATEC Energy Monitoring Systems
SATEC energy monitoring systems can combine multifunction power meters, multi-circuit metering, communications and ExpertPower software. The exact meter selection depends on the number of circuits, required accuracy, communications, billing requirements and the level of power-quality analysis required.
| Requirement | Typical SATEC family / solution |
|---|---|
| General feeder / panel monitoring | EM133, PM130 / PM135 and other suitable multifunction meters |
| Advanced multifunction metering | PRO Series / PM17x PRO depending on application |
| Multi-circuit monitoring | BFM136 / BFM-II |
| Advanced PQ + energy monitoring | Selected PQ-capable PRO configurations / PM180 |
| Central data analysis | ExpertPower |
Frequently Asked Questions
What is an energy monitoring system?
An energy monitoring system combines meters, communications and software to collect and analyze electrical consumption and operating data across a facility.
What does an energy monitoring system measure?
Active and reactive energy, demand, power factor and load profiles can be monitored together with voltage, current, power and frequency. Additional power-quality parameters depend on the selected meter.
How do energy monitoring solutions reduce energy costs?
They show when and where energy is consumed, helping teams identify waste, abnormal loads and peak-demand issues, then verify the effect of corrective actions over time.
Where can energy be monitored in a building or plant?
At the main incomer, distribution boards, floors, tenants, HVAC systems, production areas, equipment groups or individual feeders.
What is the difference between energy monitoring and power monitoring?
Energy monitoring focuses mainly on consumption and trends over time, while power monitoring focuses more on instantaneous electrical conditions. Many modern systems provide both.
Can an energy monitoring system integrate with BMS or SCADA?
Yes. Depending on the meter and system architecture, energy data can be integrated with BMS, SCADA and other monitoring platforms using supported industrial communication protocols.
Can energy be monitored by tenant or department?
Yes. Submetering and multi-circuit metering can separate consumption by tenant, floor, department, feeder or equipment group.
What equipment is needed for energy monitoring?
A typical system includes power or energy meters, suitable sensors, communications and monitoring software. The architecture depends on the number of measurement points and the required analysis.
