# What will a lender want to see for a compressed air upgrade loan?

Canonical: https://senseible.earth/answers/green-loan-compressed-air-system-upgrade

Show 6 to 12 months of electricity bills and compressor run hours before the upgrade, the supplier quote with rated specific power, and a leak survey. After installation, show the same records again. The saving in kWh times the grid factor is the carbon benefit lenders can read.

## Before the project

- Monthly electricity bills.
- Compressor run and load hours, or a sub-meter reading.
- Leak survey or air audit report.

## After the project

- Same bills and run hours for the same months.
- Commissioning report for the new compressor or dryer.

## What lenders look for

A measured baseline, a clear link between the asset and the saving, and figures that compare like with like after allowing for production changes.

## Worked example

- Before: 18,000 kWh a month on compressors
- After: 13,500 kWh a month for the same output
- Saving: 4,500 kWh x 0.710 kg = 3.2 t CO2 a month, about 38 t a year

Illustrative. Use your own sub-meter or bill figures.

## What Senseible does here

Senseible measures your baseline from your own bills before the project and keeps measuring after it, so the saving you show a lender comes from documents, not a brochure. Lenders decide on the loan.
