Backtest the structure against real NEM settlement data. Layer on the DNSP network cost stack from your own tariff schedule. Price the interconnector congestion risk through IRSR auction spreads. All in one tool, A$1,499/month — versus A$25,000 to A$80,000 for an equivalent advisory engagement.
A typical single-site corporate PPA evaluation runs as a multi-week advisory engagement with a specialist consultancy. The deliverable is a slide deck and a spreadsheet — both static, both out of date the moment the next AEMO dispatch interval clears.
A quoted PPA $/MWh covers the wholesale half of your delivered electricity cost. The DNSP network charges (demand, energy, fixed) layered on top often add A$30–80/MWh. Without modelling both halves together, the PPA looks cheaper than it is.
If your PPA is in a different region from your load, IRSR settlement residue spreads are the market-implied price of that congestion risk. Spreadsheets don’t price it. The buyer who ignores it is short an option they didn’t know they sold.
Test fixed-price, cap-and-floor, indexed, and bespoke PPA structures against the full NEM settlement history. Seasonal profiles, CPI indexation, counterparty exposure metrics, and a settlement-waterfall chart that breaks the saving down quarter by quarter — not a single average.
Upload your DNSP tariff schedule (PDF or workbook) and gridIQ extracts the demand, energy, and fixed charges per customer class. The backtester layers the network cost stack on top of spot or contract prices so a quoted PPA $/MWh is benchmarked against the all-in delivered cost — not just the wholesale half.
Inter-regional settlement residue spreads from AEMO’s SRA auction results. The market’s own price of interconnector congestion risk on every NEM cross-border path. If your PPA generator and your load sit in different regions, this is the spread you’re implicitly long or short.
Track retail and wholesale contracts with mark-to-market valuations against current spot prices. See exposure as it changes interval by interval — not at quarter-end when settlement statements arrive.
A reliability and output-consistency score for every tracked generator. Rank counterparties before signing — a 5% delivery shortfall on a 10-year PPA is the difference between a good deal and an expensive one.
