BESS augmentation is a revenue decision, not just a hardware one.
ACCURE's BESS augmentation planning service sizes and times augmentation on real degradation data, with the CapEx evidence boards and lenders trust.
Augment too early and you waste capital. Too late and you lose revenue.
Batteries age and markets move. Without accurate life curves and a timed plan, usable capacity slips and revenue leaks away. Strategic augmentation blends health forecasting, cost curves and evolving chemistries to add the right capacity at the right time, keeping assets above contract thresholds and getting every megawatt-hour of value from the investment.
BESS augmentation services we offer.
ACCURE's BESS augmentation planning service forecasts and times capacity decisions on real degradation data, drawn from 24+ GWh of supported capacity across 100+ sites worldwide.
Predict future needs with confidence
Forecasting from real-world usage data predicts when and where your systems will need augmentation, up to two years ahead, so you plan upgrades early and avoid surprises.
Maximise usable energy before expanding
Before you buy new containers, we identify recoverable capacity, so you optimise what you already have and avoid hardware you don't need.
Take control of battery lifecycles
System-level insight and long-horizon planning replace reactive fixes, aligning augmentation with maintenance and investment cycles to protect long-term value.
Turning accelerated aging into extra capacity.
Challenge
ACCURE’s health tracking showed the cells in a 100+ MWh BESS had lost ≈ 6 % more capacity than the supplier’s warranty allowed within the first two years. The original augmentation plan (adding 1.8 MWh in year 2) would not keep the plant above its required usable-capacity threshold, risking lost revenue and warranty disputes.
ACCURE insights
By comparing the real-life State-of-Health curve with the contractual warranty line, we quantified the shortfall and calculated how much additional energy was needed to stay compliant until the next scheduled augmentation.
Outcome
Using ACCURE’s evidence, the operator successfully claimed an extra 1.45 MWh of warranty-funded augmentation, raising the year-2 top-up from 1.8 MWh to 3.3 MWh. The additional capacity (valued at ≈ $217k) secures site performance, preserves revenue, and keeps the supplier, not the operator, responsible for the accelerated ageing.

How we help with BESS augmentation planning.
ACCURE pairs predictive battery analytics with performance engineers to forecast site-level augmentation needs up to two years ahead. We tell you when to augment, how much and what the financials support, so you plan cost-efficient expansions, protect revenue and give boards and lenders the evidence behind every CapEx decision.
FAQs
ACCURE's BESS augmentation planning service forecasts degradation on real operational data and translates it into a timed, sized plan, telling you when to augment, how much, and what the financials support.
ACCURE sizes augmentation on real degradation data and first identifies recoverable capacity, so you avoid over-building and only add the capacity the asset needs.
Yes. ACCURE produces the CapEx evidence boards and lenders rely on to sign off augmentation spend.
When degradation forecasts show usable capacity approaching your contractual thresholds. ACCURE forecasts up to two years ahead so you can time augmentation precisely rather than reactively.
Often, yes. ACCURE identifies recoverable and stranded capacity first, which can defer or reduce the hardware you need to buy.
