What is Green Button data?

Green Button is a national standard that lets US utility customers download their own interval usage data (typically 15-minute or hourly reads) as an ESPI XML file. Most major utilities — including Georgia Power, FPL, Duke Energy, PG&E, SCE, ConEd, and many others — offer a “Green Button Download” or “Download My Data” button inside your online account.

What the audit shows you

• Hourly load profile — when you use electricity and how peaky your day is
• Baseline vs. active load — how much you'd spend even if nobody was home
• Waste hours — the biggest chunks of avoidable consumption
• Personalized recommendations — ranked by dollar impact, not generic tips
• Rate plan fit — whether time-of-use pricing would save or cost you money based on your actual pattern

How to get your Green Button file

1. Log in to your utility's online account portal
2. Look for “Green Button Download,” “Usage Data,” or “Download My Data”
3. Choose XML format (ESPI) — not CSV or PDF
4. Pick the longest date range available (12 months is ideal)
5. Upload the .xml file here
