What’s New in TWAICE Energy Storage Analytics – Summer 2025

Penalty Risk Assessment: Finally, a Way to Stay Ahead of Costly SOC Errors

State of charge (SoC) inaccuracies are not just an annoyance – they're a multimillion-dollar issue. Whether it’s under-delivery penalties, ancillary service fines, or failing capacity tests, poorly managed SoC can tank revenues and ruin trading confidence.

That’s why the new Penalty Risk Assessment feature is a game changer. It lets users:

• Identify risky SoC windows that could trigger deratings or penalties

• Understand which specific components are driving SoC errors

• Get clear, actionable recommendations to reduce penalty risks

Think of it as a heat map for hidden danger zones in your storage system — highlighting issues so you can address them before they escalate into costly penalties.

Next-Level Warranty & Guarantee Tracking: From Manual Hassle to Automated Clarity

Warranty compliance shouldn’t be a mystery. The updated Warranty & Guarantee Tracker transforms the process by letting users:

• Map any warranty contract to real-time KPIs (over 15 metrics, 50+ configurations)

• Monitor system- and rack-level compliance

• Stay on top of contract breaches with instant notifications

This tool translates uncertain data into clear insights and adds a neutral third-party perspective for greater confidence in warranty matters.

Usable and Recoverable Energy: From Black Box to Actionable Insight

Availability metrics are often too vague to be useful. TWAICE’s Usable and Recoverable Energy feature digs deeper:

• Breaks down losses due to aging vs. correctable issues (like non-operating strings or cell imbalances)

• Analyzes both DC and AC sides, including charge/discharge inefficiencies

• Calculates real usable energy at the point of interconnection (where it actually matters)

It’s an invaluable view for operators looking to prioritize fixes with the biggest impact on system output—and therefore revenue.

Data Explorer: Root Cause Analysis, Now Supercharged

Let’s face it: BESS generate a lot of data — up to 100x more than PV systems. That’s why we revamped how operators can visualize and analyze BESS time-series data. With our new Data Explorer, you can:

• Navigate big datasets faster and easier

• Speed up investigations and troubleshooting

• No coding required—just filter and zoom to view the right data

You can now isolate anomalies (like a weak cell), dive into historical patterns, and export insights — all within minutes. Engineering teams get the depth they need without the time drain of traditional tools.

Notes & Reports: Better Collaboration, Smarter Tracking

Our product team added some thoughtful touches to streamline teamwork:

• In-App Notes: Flag issues directly in the dashboard with comments and tags (e.g., “check rack 5.5.8 on next visit”)

• Historic Reports: Create reports retroactively, not just for the current time frame

• Warranty KPIs in Reports: So you don’t miss a critical breach buried in pages of data

These updates are small on the surface, but massive for day-to-day operational efficiency.
