SCADA and Its Use in Battery Energy Storage Systems (BESS)

July 27, 2025/2 Comments/in Energy Storage Sysytem/by Rahul Jalthar

In today’s rapidly evolving energy sector, Battery Energy Storage Systems (BESS) play a vital role in grid stability, renewable energy integration, and peak load management. But what ensures their efficient, safe, and reliable operation? The answer lies in a powerful control system known as SCADA.

What is SCADA?

SCADA stands for Supervisory Control and Data Acquisition. It is a software-based control system that allows for real-time monitoring, data collection, and automation across industrial operations. Originally used in manufacturing and utilities, Supervisory Control and Data Acquisition has become a critical component in energy systems, particularly in BESS applications.

Core Components of SCADA

Human-Machine Interface (HMI): Visual dashboards for system operators
Supervisory System: Central software for data processing and visualization
Remote Terminal Units (RTUs): Interface devices to collect field data
Programmable Logic Controllers (PLCs): Execute control actions locally
Communication Infrastructure: Ensures reliable data flow between components

How SCADA Supports BESS Operations

The use of SCADA in BESS enhances safety, performance, and lifecycle optimization. Here’s how:

1. Real-Time Monitoring

Supervisory Control and Data Acquisition continuously tracks key BESS parameters like:

State of Charge (SOC)
State of Health (SOH)
Battery voltage and current
Temperature and humidity
Power inflow/outflow

Operators receive instant alerts on anomalies, enabling quick responses.

2. Remote Control and Automation

With SCADA, operators can control charging/discharging remotely. Automatic triggers can be set based on:

Load demand
Time-of-use pricing
Renewable generation availability

This ensures optimized energy dispatch and cost savings.

Enhancing Safety and Reliability

Safety is a top concern in BESS installations. Supervisory Control and Data Acquisition plays a proactive role through:

3. Fault Detection and Alarm Systems

SCADA immediately flags:

Overvoltage or undervoltage
Overtemperature
Communication failures
Smoke or fire detection

By generating alarms, it helps prevent damage and ensures operator safety.

4. Data Logging and Predictive Maintenance

Supervisory Control and Data Acquisition stores historical data for:

Performance analytics
Trend forecasting
Predictive maintenance

Analyzing long-term patterns helps in scheduling maintenance before failure occurs.

SCADA in Grid-Tied and Off-Grid BESS

Supervisory Control and Data Acquisition is essential whether the BESS is part of:

Grid-connected systems (for peak shaving, frequency regulation)
Off-grid systems (microgrids in remote areas)

In both cases, Supervisory Control and Data Acquisition enhances coordination with solar, wind, diesel generators, and load centers.

Integration with EMS and IoT

Modern Supervisory Control and Data Acquisition systems integrate seamlessly with:

Energy Management Systems (EMS) for optimized energy flow
IoT sensors for edge-level intelligence
Cloud platforms for remote access and analytics

This enables smart decision-making across the energy ecosystem.

Conclusion: SCADA Enables Smart, Safe, and Scalable BESS

The use of SCADA in BESS is not just a technical convenience—it is a necessity for scaling clean energy systems. With advanced monitoring, remote control, data analytics, and real-time fault detection, SCADA ensures that battery storage systems operate at peak efficiency, safely and reliably.

As the world moves toward decentralized, renewable energy, Supervisory Control and Data Acquisition is the silent powerhouse keeping storage systems smart and resilient.

How EMS Enables Advanced Grid Services Through BESS

July 26, 2025/1 Comment/in Energy Storage Sysytem/by Rahul Jalthar

Battery Energy Storage Systems (BESS) are evolving beyond just storing energy. With the intelligence of Energy Management Systems (EMS), they’re becoming powerful grid assets. From frequency regulation to voltage control, EMS unlocks a suite of advanced grid services that were once limited to traditional power plants.

Let’s explore how EMS empowers BESS to support modern energy grids.

What Are Advanced Grid Services?

Advanced grid services are functions that maintain grid reliability and quality. They include:

Frequency regulation
Voltage support
Black start capability
Spinning reserve
Demand response

These services ensure the grid remains stable, especially with the rising penetration of renewable energy.

EMS as the Enabler of Grid Services

The EMS is the brain that enables BESS to respond quickly, accurately, and automatically to grid signals. Here’s how:

1. Frequency Regulation

Grids must maintain a constant frequency (like 50 Hz in India or 60 Hz in the US). Sudden load or generation changes cause frequency deviations.

EMS monitors grid frequency in real time
If the frequency drops, it triggers the BESS to discharge power
If the frequency rises, BESS absorbs excess power

This dynamic response stabilizes the grid within milliseconds.

2. Voltage Support

EMS can:

Inject reactive power through the BESS inverter
Stabilize voltage at critical points in the distribution network
Prevent brownouts or overvoltage conditions

This is especially valuable in weak grids or renewable-heavy zones.

3. Black Start Capability

If the grid experiences a complete blackout, EMS-controlled BESS can:

Provide the initial jolt of energy to restart power plants
Synchronize with the grid once it’s back online
Act as a virtual power plant in microgrid scenarios

This minimizes downtime and enhances resilience.

4. Spinning Reserve

Instead of running gas turbines idle as spinning reserve, EMS can:

Keep the BESS in standby mode with real-time readiness
Dispatch power instantly when needed
Save fuel costs and emissions for utilities

5. Demand Response Participation

EMS communicates with grid operators to:

Reduce load during peak hours
Shift energy consumption schedules
Respond to market pricing signals

This not only earns revenue but also relieves grid congestion.

Real-World Example: EMS in Utility-Scale BESS

In regions like California, Australia, and Germany:

Utility-scale BESS systems managed by EMS provide daily frequency regulation
They participate in energy markets
Their fast response time outperforms conventional power plants

Why This Matters for the Future

With the global shift toward decentralized, carbon-free energy, the grid needs flexible, intelligent support. EMS in BESS enables:

✅ Fast, automated grid response
✅ Lower operational costs
✅ Greater grid reliability
✅ Deeper integration of renewables

Final Thoughts

The integration of EMS with Battery Energy Storage Systems transforms them from passive storage units into smart, responsive grid assets. As the power grid continues to modernize, EMS will play a pivotal role in delivering the advanced services that ensure stability, flexibility, and sustainability.

FAQs

Q1. Can BESS replace traditional power plants for grid services?

Not entirely, but EMS-managed BESS can supplement or even outperform them in specific services like frequency regulation and black start.

Q2. Do EMS systems need to be certified for grid services?

Yes. Compliance with grid codes, communication protocols (like IEEE 2030.5), and interoperability standards is essential.

Q3. How fast can EMS react to frequency deviations?

EMS can trigger BESS responses in milliseconds, making them ideal for fast frequency response (FFR) services.
