PG&E Green Button Usage Analyzer
Upload the usage file from PG&E's Download My Data and we'll price every hour of your real usage on E-TOU-C, E-TOU-D, EV2-A, E-ELEC and the tiered E-1 plan. You'll see your cheapest plan, how much of your usage lands in the 4-9 p.m. peak, an hour-by-month heatmap, your biggest spike days and your always-on load.
Step 1: Download your usage file from PG&E
- Sign in to your account at pge.com.
- Open My Usage (Energy Usage Details).
- Choose Green Button – Download My Data.
- Choose a date range (the last 12 months is ideal; PG&E keeps up to 3 years) and a format: CSV or Green Button XML. Pick the usage (interval) data, not billing totals.
- Export the file. PG&E may give you a .zip; upload it below exactly as downloaded.
Steps follow PG&E's Data Access Tools guide (Sign in → My Usage → Download My Data). Interval data shows up in your account about two business days after it's recorded. Menu labels on pge.com change occasionally; look for the green "Green Button" icon.

How the analysis works
- Re-pricing: every hour (or 15 minutes) of your most recent 12 months is priced at each plan's total bundled rate for its season (summer June 1-September 30) and time period: E-TOU-C peak 4-9 p.m. daily; E-TOU-D peak 5-8 p.m. on non-holiday weekdays; EV2-A and E-ELEC peak 4-9 p.m. with part-peak 3-4 p.m. and 9 p.m.-midnight; E-1 Tier 1 up to baseline and Tier 2 above.
- Credits and fixed charges: E-TOU-C's baseline credit and E-1's Tier 1 use your territory's daily baseline × the days of data in each month. The Base Services Charge ($0.79343/day) is added to every plan. With less than a year of data the annual figure is scaled up from the days you have, which can over- or under-state seasonal plans.
- Not included: taxes and city fees, the California Climate Credit, CARE/FERA discounts, Community Choice Aggregator generation rates, medical baseline and solar export credits. With solar, only grid imports are priced.
- Sources: Schedule E-TOU-C, Sheet 2, Schedule E-TOU-D, Sheet 2, Schedule EV2, Sheet 2, Schedule E-ELEC, Sheet 2, Schedule E-1, Sheet 1. Rates effective June 1, 2026, last checked October 26, 2026. This is an estimate, not a PG&E quote; confirm in your PG&E account before switching. You can change plans online; PG&E's tariff rules limit how often.
No file handy? The PG&E rate plan calculator gives a quick estimate from your monthly kWh and 4-9 p.m. share.
Frequently asked questions
Where do I get my PG&E usage file?
Sign in to your account at pge.com, open My Usage (Energy Usage Details), and choose Green Button "Download My Data". Pick CSV or Green Button XML and a date range, then download. PG&E keeps up to three years of hourly or 15-minute data for SmartMeter customers.
Which file format should I choose?
Either works. CSV is easiest to open yourself; Green Button XML is the machine-readable standard. Choose the hourly or 15-minute (interval) data, not daily or billing totals, and 12 months if you can so every season is included. If PG&E gives you a .zip, upload the .zip as is.
Do you store my file?
No. The file is read in memory on our server, analyzed, and discarded when the page responds. We do not save the file, your interval readings or the results, and you do not need an account.
How accurate is the plan comparison?
It applies PG&E's published total bundled rates hour by hour to your real usage, including seasons, peak windows, E-TOU-D holidays, baseline credits and the Base Services Charge. It is still an estimate: it assumes PG&E generation (not a CCA), and leaves out taxes, the California Climate Credit, CARE and FERA discounts and solar export credits.
Can I use this if I have solar?
You can, but the comparison only prices the electricity you import from the grid. NEM 2.0 netting, the annual true-up and Net Billing Tariff export credits are not modeled, and Net Billing Tariff customers must stay on E-ELEC.
What is baseline load?
It is the power your home draws all the time, even at 3 a.m.: refrigerators, routers, standby electronics, pool pumps and so on. We estimate it from the lowest hour of each day. Every 100 watts of always-on load is about 876 kWh a year.
