Charge Trace

Batteries are becoming the NEM's marginal intraday balancing technology. They do not create energy; they move it through time, absorb surplus supply, respond to frequency deviations and preserve scarce capacity for periods when the system values flexibility most. As more batteries connect, their collective behaviour increasingly shapes the prices from which they earn revenue.

Charge Trace tests how that transition appears in public evidence. It reconstructs what selected batteries did at five-minute resolution, estimates the observable value of energy and FCAS enablement, and compares actual operation with a transparent, price-only hindsight benchmark. The purpose is not to estimate participant profit. Private contracts, degradation costs, network obligations, losses and trading intent remain outside the public dataset. Energy value integrates signed SCADA output against the regional RRP; FCAS value is enabled MW × service price ÷ 12 across ten Raise and Lower services; both exclude losses, fees, hedges and settlement metering.

The central commercial question is whether growing battery volume creates more value or competes it away. More capacity can shift more renewable energy, reduce extreme prices and strengthen the grid, while simultaneously compressing arbitrage spreads and ancillary-service prices. Charge Trace therefore treats dispatch, stored energy, market value and fleet growth as one connected story. Refreshed weekly, it is an independent research and post-trade intelligence view, not a live operational terminal, and every estimate retains a visible method and boundary.
