Remote Monitoring Software for Grid-Level Energy Storage Systems

Differences Between EMS, SCADA, and BMS

With the rapid increase in renewable energy investments, grid-scale energy storage systems (GSS) are no longer just batteries. Advanced software infrastructures play a critical role in ensuring these systems operate safely, efficiently, and sustainably.

So, what is the main software that remotely monitors and manages the entire structure in these large-scale energy storage systems? The answer: EMS – Energy Management System.

In this article, we will discuss EMS, SCADA, and BMS layers, the differences between them, and Batron Energy's approach in this field.

What is EMS (Energy Management System)?

EMS is the main software layer that remotely monitors, analyzes, and manages the entire structure in grid-level energy storage systems.

EMS's Core Tasks

Monitoring the entire BESS system from a single center

Charging/discharging optimization

Load balancing

Frequency regulation (FR)

Peak shaving & peak shifting

Algorithmic decisions based on energy prices

Communication with grid operators (TEİAŞ / DSO)

Integration with SCADA, PCS, and BMS systems

In short, EMS is the "brain" that decides when, how much, and for what purpose energy will be used.

SCADA: Visualization and Operation Layer

SCADA (Supervisory Control and Data Acquisition) is the layer where decisions made by EMS are visually presented to operators and implemented.

The Role of SCADA

Real-time monitoring screens

Alarm and event management

Graphs, trends, reports

Remote on/off commands

Operator intervention interface

📌 SCADA does not make decisions; it implements and makes traceable the decisions made by the EMS.

BMS: Battery Safety and Health

The BMS (Battery Management System) is the most critical subsystem operating at the battery level.

What does the BMS do?

Monitors cell voltages

Performs temperature control

Calculates SOC/SOH

Provides protection against risks such as overvoltage, undervoltage, and overtemperature

The BMS sends data to the EMS, but it is not the software that manages the entire system.

How does the Software Architecture Work in Grid-Scale BESS?

A typical grid-level energy storage architecture is as follows:

Grid Operator (TEİAŞ / DSO)

↑

EMS (Cloud or On-Premise)

↑

SCADA

↑

PCS (Inverter Control)

↑

BMS

↑

Battery Racks

This structure allows the system to be managed securely both locally and remotely.

Cloud-Based Remote Monitoring Platforms

Today, EMS and SCADA systems are mostly moved to the cloud environment with features such as:

Web-based panels

Mobile access

API / MQTT / REST infrastructures

Multiple site management

This allows energy storage facilities located in different cities or countries to be monitored from a single center.

Batron Energy's Approach

Batron Energy Inc. offers domestic and customizable solutions in grid-level and industrial energy storage projects in the following areas:

BMS development

EMS algorithm design

System integration

Container-type energy storage solutions

Li-ion, LiFePO₄, and Na-Ion battery technologies

and more.

In systems developed by Batron:

EMS is specially configured according to project needs

SCADA layer can be integrated with open-source or commercial platforms

Compliance with IEC 60870-5-104 / IEC 61850 is targeted for TEİAŞ (Turkish Electricity Transmission Corporation) and distribution companies

Energy management strategies specific to battery chemistry (LiFePO₄ / Na-Ion) are implemented

Thanks to this approach, Batron Energy offers not only hardware but also an end-to-end energy management ecosystem.

In grid-level energy storage systems:

EMS is the main software that remotely monitors and manages the entire system.

SCADA is the operation and visualization layer.

BMS ensures the safety of the battery.

A well-designed EMS + SCADA + BMS architecture is the key to ensuring that energy storage projects are efficient, safe, and long-lasting.
