What it will and will not do
What it will do
- Read a half-hourly meter file from your own device. It is read in your browser, not uploaded.
- Take a tariff you enter yourself: supply charge, rates, time windows, any daily cap and its excess rate, and the feed-in rate.
- Add up what the same half-hours would have cost, month by month, with the assumptions beside the result.
- Show one household's comparisons as worked examples.
What it will not do
- Model different battery behaviour. It replays the half-hours as recorded.
For the whole market
To compare every offer for your address, use Victorian Energy Compare or Energy Made Easy. The bill replay answers a different question: what your own half-hours would have cost on one tariff.
Meanwhile
The free-window calculator is live. It works out how full a battery gets in a free window.
