Energy Data and Utility Bill Audit in New York City
Clean, validated utility data and bill audit for buildings and portfolios across New York City, New York. MartinAI reads every commodity and format, checks it, and turns it into numbers you can report and act on.
Every building in New York City generates a steady stream of utility bills across electricity, natural gas, water, and sometimes steam or district energy. Read one at a time, they are just paper. Assembled, validated, and understood, they are the clearest record of how a building actually performs. Anchored by New York City in finance, media, insurance, healthcare, and technology, with manufacturing, higher education, and agriculture across upstate regions. As a city in the United States, New York City has its own utilities, regulator, and reporting rules, and this page covers what that means for your data.
The energy picture in New York City
| Grid carbon intensity | about 211.6 g CO2e/kWh (2023) |
|---|---|
| Grid mix | Gas, hydro, and nuclear (gas 47%, hydro 23%, nuclear 22%) |
| Main electricity utilities | Consolidated Edison (Con Edison), National Grid, New York State Electric & Gas (NYSEG), Rochester Gas and Electric (RG&E), Central Hudson Gas & Electric, and Orange and Rockland Utilities |
| Main gas utilities | Consolidated Edison (Con Edison), National Grid, National Fuel Gas, and Central Hudson Gas & Electric |
| Energy regulator | New York State Public Service Commission (Department of Public Service) |
New York City draws from the New York grid, so its electricity carbon intensity reflects that grid. At about 211.6 grams of CO2e per kilowatt-hour (2023: https://www.epa.gov/system/files/documents/2025-06/summary_tables_rev2.pdf)), electricity here carries a middling carbon intensity. Both electricity and fuel reductions move the number, which makes accurate, commodity-by-commodity data the difference between a defensible emissions figure and a guess.
On the ground in New York City
- Electricity is delivered locally by Con Edison, within the New York State Public Service Commission (Department of Public Service) framework.

What MartinAI delivers in New York City
Whether a building is served by Consolidated Edison (Con Edison), National Grid, and New York State Electric & Gas (NYSEG), or any other provider, MartinAI reads its utility bills across every commodity and layout, separates true consumption from delivery, demand, and tax lines, and validates each figure before it reaches a report. The result is one clean record per building that you can analyze, benchmark, and hand to an auditor.
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 New York City
An audit is where clean data pays for itself. With every bill in New York City read and validated, the anomalies surface: a wrong rate class, a demand charge inflated by one bad interval, tax applied where it should not be, consumption billed to the wrong meter. Industry figures put utility billing errors at 2.5 to 10 percent of spend, so the recovery is often material.
Reporting and compliance in New York
New York City runs the country's largest program: Local Law 84 requires annual energy and water benchmarking for buildings over 25,000 square feet, and Local Law 97 sets greenhouse gas emission caps with penalties that began with the 2024 compliance year, first reported by year-end 2025. There is no statewide building performance standard yet.

Frequently asked questions
Can MartinAI handle utility bills from New York City and New York?
Yes. MartinAI reads utility bills across every commodity (electricity, natural gas, water, steam, and fuels) and every layout used by utilities in New York, then validates each figure. Local formats and multi-meter accounts are exactly what it is built for.
What is the grid carbon intensity in New York City?
Grid electricity in New York City, which sits on the New York grid, is about 211.6 grams of CO2e per kilowatt-hour (2023). MartinAI pairs your validated consumption with the right local emission factor so your Scope 2 numbers are accurate.
Do you help with energy reporting rules in New York?
New York City runs the country's largest program: Local Law 84 requires annual energy and water benchmarking for buildings over 25,000 square feet, and Local Law 97 sets greenhouse gas emission caps with penalties that began with the 2024 compliance year, first reported by year-end 2025. There is no statewide building performance standard yet. 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.
