Half-hourly electricity analyser

Load one Excel or CSV file of half-hourly readings per meter. The analyser checks the data, then shows out-of-hours use priced at your rates, base load, peaks against your agreed supply capacity, unusual days and lasting changes, with PDF and Excel reports.

It runs entirely in your browser: your meter data is never uploaded. It needs JavaScript and a recent desktop browser such as Chrome or Edge.
