Recover 1.5%+ of usable capacity. Extend asset life by 15%

The Intelligence Layer for Grid-Scale Battery Assets

When hundreds of batteries operate behind a single dispatch command, estimation errors compound and the weakest unit constrains the system. Altergo's digital twin platform eliminates that gap, recovering capacity, extending life, and preventing incidents across the fleet.

Extend Asset Life & Defer Augmentation

Add 2–5 years to a 15-year asset by managing degradation with physics, not calendars.

Add 2–5 years to a 15-year asset by managing degradation with physics, not calendars.

Without cell-level health visibility, operators derate and plan augmentation on conservative calendar schedules. Altergo's physics-based degradation models and impedance tracking produce condition-based RUL forecasts that defer augmentation by years — without compromising safety or warranty compliance.

Shift from reactive alarms to quantified, forward-looking risk management.

Safety events are the result of slow-moving deviations — impedance growth, plating, thermal gradients — that standard BMS misses until they cross a threshold. Altergo detects these precursors across the fleet and surfaces risk indices with recommended actions, producing evidence-grade outputs for regulators and insurers.

Normalise performance visibility across OEMs, chemistries, and procurement cycles.

Multi-site BESS portfolios span different vendors, ages, and chemistries — making like-for-like comparison impossible with standard tools. Altergo benchmarks every container against its peers, identifies root causes of deviation, and quantifies how operating strategies affect degradation across the fleet.

Maximize Dispatchable Energy

Recover the 5–7% of purchased capacity that conventional BMS margins leave stranded.

Recover the 5–7% of purchased capacity that conventional BMS margins leave stranded.

BMS estimation errors (±3–5% per battery) compound across hundreds of co-dispatched containers, locking away 5–7% of purchased capacity on every cycle. Altergo's SoE/SoP models collapse that uncertainty, recovering stranded energy as incremental revenue for the life of the asset.
