Case Study: InterEnergy restores BESS capacity and secures warranty claims with TWAICE Energy Storage Analytics

InterEnergy restores 1.4 MWh of capacity with TWAICE

InterEnergy, an energy provider operating the largest battery energy storage system (BESS) in the Central American and Caribbean region, faced challenges in monitoring its 40+ MWh system's performance. Their internal team struggled with inconsistent SCADA alerts, difficulty differentiating equipment failures from data outages, and a lack of performance KPIs, which made proactive operations, maintenance, and warranty claims difficult. To address this, they implemented TWAICE Energy Storage Analytics.

The solution from TWAICE provided automated anomaly detection and root-cause analysis, converting complex BESS data into actionable insights. This enabled InterEnergy to identify and replace a defective battery string under warranty and detect an idle string, restoring 1.4 MWh of capacity. The data-driven approach empowered their team, reduced downtime, and shifted their BESS management from reactive to proactive, ensuring high system performance and supporting successful warranty claims.
