Energy Data and Utility Bill Audit in Winston-Salem
MartinAI turns the utility bills behind every building in Winston-Salem, North Carolina into clean, audited, report-ready data, across electricity, gas, water, steam, and more.
For owners, operators, and energy teams in Winston-Salem, the utility bill is the single most complete source of truth about a building, and the hardest to use. Banking and finance centered in Charlotte, technology and life sciences in the Research Triangle, plus manufacturing, agriculture, and military installations. MartinAI exists to turn that source into structured, trustworthy data. As a city in the United States, Winston-Salem has its own utilities, regulator, and reporting rules, and this page covers what that means for your data.
The energy picture in Winston-Salem
| Grid carbon intensity | about 284.1 g CO2e/kWh (2023) |
|---|---|
| Grid mix | Gas and nuclear led, with rising solar (gas 41%, nuclear 34%, coal 11%, solar 9%) |

Winston-Salem draws from the North Carolina grid, so its electricity carbon intensity reflects that grid. At about 284.1 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.

Utility bill audit in Winston-Salem
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 Winston-Salem 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.

Yes. MartinAI reads utility bills across every commodity (electricity, natural gas, water, steam, and fuels) and every layout used by utilities in North Carolina, then validates each figure. Local formats and multi-meter accounts are exactly what it is built for.
What is the grid carbon intensity in Winston-Salem?
Grid electricity in Winston-Salem, which sits on the North Carolina grid, is about 284.1 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 North Carolina?
None yet at the state level; North Carolina has a statewide commercial energy code but no mandatory building benchmarking or building performance standard, and no major city has adopted a benchmarking ordinance. 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.
