FlexGen Power Systems, a provider of battery energy storage solutions, has introduced an important update to its State of Health (SOH) feature in the HybridOS energy management system (EMS).
The enhancement provides customers with a more accurate and reliable assessment of battery degradation over time.

It facilitates long-term site planning by providing both the SOH reported by the battery management system and the SOH calculated by FlexGen’s proprietary methods.
FlexGen’s new SOH feature in HybridOS provides the insights required to optimise efficiency, plan for system upgrades, extend battery life and confidently predict capacity test outcomes.
As global energy demand is expected to rise by 4% annually through to 2027, battery energy storage systems are becoming increasingly essential.
The US is expected to add 18GW of new utility-scale energy storage capacity to the grid in 2025.
The SOH is a vital metric for monitoring battery capacity, impacting system performance, financial planning and operational strategies.
As battery health deteriorates, usable energy and power performance diminish, which restricts the amount of energy that can be dispatched and decreases revenue potential.
Many operators depend on vendor-reported SOH, which is based on uniform usage and laboratory conditions.
However, HybridOS’ proprietary SOH is calculated using actual site conditions, ensuring a more accurate representation of battery health.
The upgraded feature analyses energy flow during charging and discharging to assess degradation rates and generate a site-specific degradation curve.
This aids asset managers and site operators in planning for site augmentation, warranty claims and operational strategies that prolong battery life.
FlexGen chief technology officer Hugh Scott stated: “Our proprietary battery state-of-health algorithm delivers precise, site-level diagnostics, providing customers with deeper insights into their battery’s performance and health.
“FlexGen remains dedicated to providing advanced, actionable data analytics that help our customers optimise their asset’s performance.”
FlexGen Power Systems is supplying equipment and the HybridOS EMS for SMT Energy’s 160MW/320 megawatt hours Houston IV battery energy storage facility in the US state of Texas.
