Better Insights. Smarter Operations. Proven Impact.
Whether you manage operations, performance, or planning—TWAICE gives you the insights to detect issues early, improve reliability, and make decisions with confidence.
“As we scale up our global battery storage footprint, data intelligence isn’t just 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 that directly improve asset value and reliability.”
“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 straight to the integrator or service provider. It just works.”
“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."
”Operating battery storage is becoming an increasingly data-driven business. Independent analytics are a key enabler for actively managing performance, availability, and economic outcomes across our as well as our client portfolios. As we continue to scale, these capabilities are fundamental to how we operate and optimize battery assets.”
"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. Other tools are not able to show us the same level of detail that we need to understand how the batteries are performing."
"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."
“With battery analytics, we improve our understanding of our BESS in operation even without having an armada of operational & data analytics experts on board (yet). Using TWAICE analytics means that our team is able to become better BESS operational experts.”

The State of BESS Operations: Insights from the BESS Pros Survey 2026
It’s surprisingly difficult to understand the health and status of a battery without extensive and expensive testing, which isn’t always possible. TWAICE has been taking aim at this problem since its founding in 2018.
