GETTING STARTED

Calculate electricity bills from your interval energy data

BillSave is an independent electricity bill calculation and offer comparison platform. Upload interval CSV data to calculate supported offers from actual consumption, compare estimates and find options that better fit how you use energy.

WORKFLOW

Five steps to compare electricity offers

  1. Create or connect an account

    Create a BillSave account with your email, or continue with IAMMETER if you want to load an authorised IAMMETER Cloud Site directly.

  2. Choose a country and offer

    Select Australia or Great Britain, then review the retailer or Supplier, effective dates, quality and required inputs.

  3. Provide actual energy data

    Upload 5, 15 or 30-minute BillSave CSV data. IAMMETER users may instead load a Cloud Site; Australian users can also upload NEM12.

  4. Calculate the bill

    Apply the supported tariff rules to the selected billing period and review the estimate, assumptions, coverage and component breakdown.

  5. Compare and find a better fit

    Use the same immutable energy revision across selected offers, or use Find Best to rank executable offers for the same measured usage.
