Probabilistic Energy-storage Assessment.

Make every battery hour earn — without spending its calendar life.

A multi-period state-of-charge optimiser that value-stacks energy arbitrage with frequency response and balancing-mechanism revenue across all simulated hours — while respecting round-trip efficiency and degradation.

The signature output

Charge cheap, discharge into the peaks.

A representative day of optimised dispatch — state of charge following the spot price, with charging and discharging windows shaded.

Value-stacking lifts revenue +135% over price-arbitrage alone — but only if degradation is priced in. PEA solves both simultaneously.
Inside the engine

One optimiser, every revenue stream.

01

Multi-period SoC

A MILP over half-hour settlement co-solves arbitrage, frequency-response availability and balancing bids.

02

Stochastic scenarios

All simulated hours of price and frequency — Parquet-backed for sub-minute access.

03

Degradation-aware

Round-trip efficiency and cycle/calendar ageing priced into every dispatch decision.

04

Value-stack output

A bankable revenue stack and an end-of-life trajectory the lender can underwrite.

The read

Value-stacking lifts revenue +135% over arbitrage alone — and PEA proves it without quietly burning the asset's calendar life.
