Energy Management System (EMS)
Turning Energy Data into Operational Decisions
An Energy Management System (EMS) provides real-time insight into how energy is used, where losses occur, and how power quality solutions actually perform over time.
At Acuity Solutions, EMS is not just monitoring —
it is the foundation for measurable, long-term energy optimization.

Why Energy Visibility Matters
Without accurate and continuous measurement, organizations often face:
-
Rising energy costs without clear explanation
-
Difficulty verifying savings from installed solutions
-
Limited insight into load behavior and power quality issues
-
Reactive decision-making instead of strategic control
-
ESG and reporting challenges without reliable data
Energy that is not measured cannot be managed.
How an EMS
Works
An EMS collects, analyzes, and visualizes energy and power quality data
across electrical systems, processes, and time.
Core operating principle
-
Continuous data collection from meters and sensors
-
Real-time visualization of energy and power quality parameters
-
Analytics to identify inefficiencies, anomalies, and trends
-
Reporting and benchmarking for decision support
-
Integration with corrective solutions and operational actions
This transforms raw data into actionable intelligence.
Active Power Filter (APF)
Controlling Harmonics to Protect Power Systems and Equipment
While these technologies improve operational efficiency, they also generate harmonic distortion, which degrades power quality and creates hidden risks within the electrical system.
An Active Power Filter (APF) is designed to detect, analyze, and compensate harmonic currents in real time, restoring waveform quality and stabilizing the electrical network.

Automation-intensive production lines
Data centers and mission-critical loads
What Are Harmonics — and Why They Matter
Harmonics are electrical distortions caused by non-linear loads drawing current in irregular waveforms. Instead of a smooth sinusoidal current, the system experiences distorted waveforms that lead to:
-
Overheating of transformers, cables, and switchgear
-
Nuisance tripping of circuit breakers and protection devices
-
Reduced efficiency of electrical equipment
-
Increased system losses and operational instability
-
Interference with sensitive electronics and control systems
These issues often do not appear in basic energy bills,
making them difficult to detect without proper measurement.
How an Active Power Filter Works
An APF continuously monitors the electrical system and performs three key functions:
-
Real-time harmonic detection
The APF measures load currents and identifies harmonic components generated by non-linear loads. -
Dynamic compensation
It injects equal and opposite harmonic currents into the system, effectively canceling distortion. -
Adaptive performance
Compensation adjusts automatically as loads change, ensuring consistent performance under dynamic conditions.
Unlike passive filters or fixed capacitor solutions, APF performance remains effective even under rapid load variation.
Static Var Generator (SVG)
Dynamic Reactive Power Compensation for Stable Power Systems
Traditional capacitor banks are often unable to respond fast enough to modern load behavior, especially in facilities with rapidly changing or highly dynamic loads.
A Static Var Generator (SVG) provides real-time reactive power compensation,
maintaining voltage stability and power factor under continuously changing operating conditions.

When SVG Is the Right Solution
SVG is particularly effective in facilities with:
Rapidly fluctuating loads
Limitations of traditional capacitor banks
Low or unstable power factor
Processes sensitive to voltage variation
Why Reactive Power Matters
Reactive power does not perform useful work, but it directly affects the efficiency, stability, and cost of an electrical system.
Poor reactive power control can lead to:
-
Low or unstable power factor
-
Voltage fluctuation and instability
-
Increased current and system losses
-
Utility penalties and higher electricity costs
-
Reduced capacity of transformers and cables
These issues often worsen in facilities with:
-
Large motors and compressors
-
Variable-speed drives (VSD)
-
Automation and batch processes
-
Frequent load variation
How a Static Var Generator Works
An SVG continuously monitors system conditions and dynamically injects or absorbs reactive power.
Operating principle
-
Real-time measurement of voltage, current, and reactive power
-
Instant calculation of reactive power demand
-
Dynamic generation of inductive or capacitive current
-
Continuous adjustment as load conditions change
Unlike fixed capacitor banks, SVG response is instantaneous and adaptive,
making it suitable for highly dynamic systems.
Energy Saving Module (ES Module)
Voltage Optimization & Stabilization for Efficient and Reliable Power Systems
In many industrial and commercial facilities, supply voltage is higher or more unstable than required for actual load operation. While this often goes unnoticed, it can lead to unnecessary energy consumption, equipment stress, and long-term reliability issues.
The ES Module is designed to optimize and stabilize voltage levels,
ensuring electrical systems operate within an efficient and safe range based on real site conditions.

When the ES Module Is the Right Solution
The ES Module is particularly effective in facilities with:
Consistently high incoming voltage
Equipment sensitive to voltage variation
Voltage fluctuation affecting equipment performance

Why Voltage Matters More Than You Think
Electrical equipment is designed to operate within a specific voltage range.
When supply voltage is consistently above or outside optimal levels, it can result in:
-
Excess energy consumption
-
Increased heat generation in motors and equipment
-
Reduced equipment lifespan
