Upload your DNSP tariff schedule and gridIQ extracts demand, energy, and fixed charges — then layers them directly onto your PPA backtest.
A quoted PPA price is a wholesale electricity rate. It does not include the network charges — demand, energy, and fixed charges levied by your distribution network service provider (DNSP) — that make up 30–50% of a large energy buyer's total electricity cost.
Evaluating two competing PPAs without network charges produces a distorted comparison. The contract with the lower flat rate may have a worse outcome after network charges are applied against the actual demand profile — particularly for sites with high peak demand or time-of-use exposure.
gridIQ's Network Tariff Cost Stack extracts DNSP charges from your tariff document and applies them in the PPA backtesting engine alongside your half-hourly consumption data, so the backtest comparison reflects all-in delivered cost.
Paste in your DNSP network tariff document — PDF or workbook format. gridIQ's universal parser extracts the charge structure automatically.
Demand charges ($/kVA or $/kW), energy charges ($/kWh by time-of-use band), and fixed charges are identified per customer class. You review and confirm the extracted values before they are applied.
The network cost stack is applied to the PPA backtesting engine alongside your half-hourly consumption data. The result shows the all-in delivered cost comparison — wholesale contract price plus network charges — against the uncontracted spot baseline.
Because demand charges are applied against the actual demand profile in the backtest period, peak demand reduction events (curtailment, battery dispatch) show their true savings impact on the full network cost stack.
Network charges — demand, energy, and fixed — typically represent 30–50% of total electricity cost for large commercial and industrial customers. Evaluating a PPA on wholesale price alone ignores a substantial portion of the delivered cost. A PPA that looks attractive on a $/MWh basis may not deliver a saving when network charges are applied against the actual consumption profile.
gridIQ's parser handles standard DNSP tariff PDF documents and workbooks from Australian distribution network service providers. Complex multi-component tariff structures (time-of-use energy, coincident peak demand, non-coincident peak demand, reactive power) are all extracted. If your tariff structure is non-standard, you can manually review and edit the extracted values before confirming.
Yes. The feature works with tariff schedules from any DNSP operating in the NEM (Ausgrid, Endeavour Energy, Essential Energy, AusNet, CitiPower, Powercor, United Energy, SA Power Networks, Energex, Ergon, TasNetworks) and WEM (Western Power).
