Product Tour! Discover TWAICE BESS Analytics in Just 5 Minutes — Watch Now!New What's New with TWAICE BESS Analytics (Summer '26 edition)

TWAICELet's talk

For BESS owners & operators

Your EMS tells you it's running. Not how it's performing.

One independent view of your whole fleet — catch issues months early, find root cause in minutes, and prove it to your suppliers.

The problem

You don't have a single source of truth for your fleet.

◔Numbers you can't trust

Your EMS may show 95% state of charge when only 80% is usable. And the SoH and RTE figures you report come from the same systems you are trying to check.

⚯Data you can't easily collect

Your data sits across many vendors (Powin, Sungrow, BYD, CATL) and systems that do not work together — often at 15-minute detail when analytics need 1-minute.

▤Evidence you can't produce

When a performance or warranty question comes up, you have no independent, forensic record of how the system actually behaved.

EMS vs. battery analytics

Your EMS runs the system. Analytics is a different job.

▣

Built for control, not analysis

An EMS runs and visualizes your system. It wasn't designed to analyze battery health, imbalances, or degradation — and neither were solar-era APM tools.

▦

Built around one vendor

It works with the system it ships with — not the mix of OEMs and chemistries a growing fleet ends up with.

▥

Supplied by the same party

It comes from your OEM or integrator, so it can't also serve as the independent check that warranty and bankability conversations rely on.

TWAICE sits on top of your EMS — making the data you already have independent, comparable, and battery-native. It works with your EMS, not against it.

“As we scale up our global battery storage footprint, data intelligence isn't a nice-to-have — it's a must-have. TWAICE gives us continuous visibility across diverse systems, flags risk before it impacts performance, and enables smarter, faster decisions.”

Alex King — Head of Asset Management

Fullmark Energy

“I log into TWAICE every morning — it gives me a clear, reliable snapshot of how our systems are performing. If something looks off, I can quickly drill down, export the data, and send it to the integrator or service provider.”

Nicholas Peri — VP Asset Management & Operations

InterEnergy

“With TWAICE, it's like being able to see into the battery data. TWAICE has helped us uncover many underperforming components that we wouldn't have found otherwise.”

Laura Perez Amigo — Operations Manager

Naturgy

“As we scale our battery portfolio, transparent and independent performance insights become increasingly important. It enables faster decision-making and stronger performance management across assets.”

Alejandro Espina Delgado — O&M Services

Green Flexibility

“TWAICE enables us to gain critical insights into the performance and aging of battery systems. This allows us not only to increase operational safety, but also to maximize the profitability of our projects.”

Hermann Schweizer — CTO

VERBUND

“TWAICE's Digital Commissioning helps us overcome the challenges of an increasingly heterogeneous system-integrator landscape and ever larger BESS systems. A must-have for baselining performance and identifying deficiencies before operation starts.”
