What MartinAI delivers in Gary
Whether a building is served by Duke Energy Indiana, AES Indiana (formerly Indianapolis Power & Light), and NIPSCO (Northern Indiana Public Service Company), or any other provider, the bills arrive in different formats and units. MartinAI reads them all, normalizes units and billing periods, flags estimated reads and gaps, and produces a consistent record you can compare across sites and months.
Data delivery
Every utility bill read across electricity, gas, water, steam, and fuels, normalized to consistent units and periods.
Bill audit
Rate class, demand, tax, and meter mapping checked against the tariff and the meter to recover overcharges.
Benchmarking
Clean records that feed ENERGY STAR Portfolio Manager and internal intensity comparisons across sites.
Emissions reporting
Consumption paired with the right local emission factor for defensible Scope 1 and Scope 2 numbers.
Utility bill audit in Gary
Utility bills carry errors more often than most teams expect. Independent figures put billing mistakes at 2.5 to 10 percent of spend and estimate that 15 to 20 percent of invoices contain errors. A bill audit in Gary means checking rate classes, demand charges, tax treatment, and meter mapping against what the tariff and the meter actually say, then recovering what was overpaid.
Reporting and compliance in Indiana
No statewide requirement. Indianapolis and Marion County operate a Benchmarking and Transparency Ordinance (Chapter 710) covering buildings 50,000 square feet and larger, with annual reporting through ENERGY STAR Portfolio Manager.

Do you help with energy reporting rules in Indiana?
No statewide requirement. Indianapolis and Marion County operate a Benchmarking and Transparency Ordinance (Chapter 710) covering buildings 50,000 square feet and larger, with annual reporting through ENERGY STAR Portfolio Manager. MartinAI produces the clean, traceable data those reports depend on.
How is this different from reading bills by hand?
Manual entry is slow and error prone, and the errors flow straight into your cost and emissions numbers. MartinAI reads and validates automatically, flags anomalies, and keeps every figure traceable back to the source bill, so the data holds up under an audit.
