Smarter SCADA + EMS for Better BESS Outcomes

Let’s keep it simple. If you work with Battery Energy Storage Systems (BESS), you already know Supervisory Control and Data Aquisition (SCADA) and Energy Management System (EMS) are important. But too often, they’re treated like a checklist item—not the core of your system’s success.

Over the years, I’ve worked on many energy systems—from solar farms to process automation. One thing is always true: a well-built SCADA system makes everything else work better. It’s how subsystems connect, talk, and respond.

EMS: The Brain of the Operation

Think of SCADA as the nervous system. EMS is the brain. It doesn’t just collect data—it makes decisions.

I’ve seen too many sites treat EMS as a “set-and-forget” tool. That’s risky.

On one BESS project, the EMS ignored stress on the local transformer. We added grid stress analytics to the EMS. The result? A 9% increase in battery life—and avoided a $2M substation upgrade.

A Smarter EMS Means Smarter Results

  • Predictive: Use weather data to plan ahead—not just tomorrow, but for long-term battery health.
  • Managing: Balance profits with the real cost of frequent charging.
  • Adaptive: Adjust in real time when the unexpected happens.

Where ACE Makes the Difference

Many teams connect SCADA and EMS like they’re strangers. We design them to work as one.

One client had a wind + BESS site losing state-of-charge (SOC). The EMS used averaged SCADA data, not detailed battery data. We fixed the data path—no hardware changes. They regained 12% of their “lost” capacity overnight.

Our Way of Working

  • Start early: Involve us during the design, not just at commissioning.
  • Connect the data: Let SCADA’s raw data guide EMS logic.
  • Think long-term: Test for real-world conditions, not just ideal ones.

How We Help

At ACE, we build SCADA and EMS systems that work together—seamlessly. Our team designs smart, reliable solutions built for your goals and future challenges.
