Upload the file the utility already gives you
Duke-style exports and interval files come in as the starting point. The work begins with the same record the customer received.
From utility export to review record.
The tool stays close to the source file so the result is easier to explain later.
Check the overnight baseline and the nights that break from it
You can see total kWh, the overnight baseline, flagged nights, and any sharp changes that show up after midnight.
Compare one export against another when the story changes
The compare mode aligns equivalent months, calls out unmatched ranges, and saves a concise artifact you can keep with the file.
Keep the result for the next conversation
The review is easier to revisit when the output already names the large deltas, the baseline shift, and the periods that match.
