2Electricity use
Type or paste one row per bill (most recent 12). kW = the demand the bill charges for; "Max kW" only if the bill prints a separate any-time maximum. Paste from Excel: Month, kWh, kW, Max kW, Bill $.
| Month | kWh | Billed kW | Max kW (any time) | Bill total $ |
|---|

| Use | Block type | kW / unit | kWh / unit | Max units | Equipment $ / unit | Equipment $ fixed | Install $ / unit | Install $ fixed | O&M $ / unit-yr | Basis |
|---|
