Uncover Underperformance

"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."

Laura Perez Amigo
Operations Manager
BESS Insurance

"In the operational phase for BESS projects, prudent asset managers can use insurance as a competitive advantage. Those that run assets with minimal oversight will face insurance premiums that are a disproportionately high share of operating costs. But complimenting existing hardware and site layout strategies with advanced battery analytics will lower your project’s risk of large, thermal runaway events."

Partner
Maximizing Profitability

"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
BESS Commissioning

"TWAICE’s Digital Commissioning helps us to overcome the challenges resulting from an increasing heterogeneous system-integrator landscape and ever larger BESS systems. A must have for baselining performance at BoL and identifying deficiencies before operation starts.”

Karl Potz
Head of Battery Solutions Center
Remaining Technologically Agile

"This partnership contributes greatly to the reliable, safe and efficient operation of our portfolio. In addition, we want to select the best possible cell technology for the future based on the evaluation of various cells by TWAICE so that we remain technologically agile."

Gabriele Schmiedel
Managing Director
Simplifying Operations

“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.”

Nicholas Peri
VP Asset Management & Operations
Gaining Visibility

“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.”

Alex King
Head of Asset Management
Empowering BESS Operations

“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.”

Julian Gerstner
Head of Storage
BESS Performance

“TWAICE’s battery analytics software enables us to go deep with the analyses of our batteries. That means we can concentrate on optimizing their performance.”
