Upload your NEM12 interval file and pick your region. We score every metered interval against the historical regional reference price it actually settled at, then conservatively back-calculate the wholesale-spot saving from shifting a bounded slice of your load to cheaper intervals. Your raw intervals are processed in memory and never stored.
Pick the region the NMI sits in. WA uses the WEM (30-min) market.
Leave blank to just see your result here. If you enter an email, we send one transactional email with a private link to your report. We don’t add you to any list. Privacy policy.
For every interval in your file, we look up the regional reference price that interval actually settled at. That gives us the wholesale-spot cost you really paid. We then move a bounded fraction of each day’s load off the dearest intervals onto the cheapest ones — within the same day only — and recompute the cost. The difference is the saving.
The estimate is deliberately conservative. Only a fifth of each interval’s energy is treated as shiftable, and we apply a capture factor to the perfect-hindsight optimum to reflect the gap between a perfect re-allocation and what a real, forecast-driven operator captures. Every assumption is listed in your result.
We never persist your raw meter intervals. The file is parsed in memory; only the masked NMI, totals and the computed result are kept — and only if you ask us to email you a report.

This tool looks backwards at your own data. The gridIQ platform looks forwards: the Load Shift Advisor surfaces the cheapest and lowest-intensity operating windows for the next 72 hours across all six Australian regions from live pre-dispatch data.
