DIY network tariff review

Match your tariff to the way you use energy.

Start with your bill and interval data. Check your network charges, or ask Bulk to help you take the next step.

A practical first check

Could a different network tariff suit your site?

Compare a complete usage year against published network prices. See the usage and demand components, the lowest modelled option in your current tariff family, and what must be confirmed before changing.

Start with the evidence.

Data time, interval length and local holidays

Fixed AEST and interval-start labels are the initial assumptions. Change them to match the export. Ambiguous daylight-saving local timestamps need explicit offsets or a fixed-AEST export.

Powercor, Endeavour, Ausgrid, CitiPower and United Energy use their Victorian or NSW holidays. Energex uses Brisbane AEST charging windows and includes public holidays; holiday edits do not alter its model. Confirm local exceptions; enter full-day removals or additions (YYYY-MM-DD, separated by commas). In Victoria this includes local Melbourne Cup replacements. Part-day exceptions need a separate review. Powercor and Endeavour calendars cover 2024–2026; the Ausgrid calendar covers 2024–2027; CitiPower, United Energy and Jemena cover 2024–June 2027. Jemena includes public holidays for weekday usage and annual demand, but excludes them for summer demand. Essential Energy keeps weekday public holidays; holiday edits do not alter its charging windows.

Interval formats, timing and email details

CSV or XLSX; ZIPs may contain supported files. NEM12 CSV supports one identified meter with an E1-only consumption configuration, in fixed AEST. Other channel configurations and NEM13 need a supported interval export. Up to eight inputs, 25 MB each. Avoid overlapping periods. For SAPN recorded demand history, include 23 complete months.

Selecting files does not send them. Email requests remain unsent drafts with manual attachments. Privacy policy.
