Energy Data Management and Utility Bill Audit in California
Utility data delivery, bill audit, and emissions reporting for California. From messy bills to structured, validated records you can trust.
Managing energy in California starts with the data buried in utility bills, and that data is messier than it looks: different formats, different units, estimated reads, and charges that hide real consumption. The largest state economy in the country spans technology, entertainment, agriculture, and a very large commercial real estate market. Getting it clean is the work that everything else depends on. As a state in the United States, California has its own utilities, regulator, and reporting rules, and this page covers what that means for your data.
The energy picture in California
| Grid carbon intensity | about 179 g CO2e/kWh (2023) |
|---|---|
| Grid mix | A mix of natural gas, solar, and hydro |
| Main electricity utilities | Pacific Gas and Electric (PG&E), Southern California Edison (SCE), and San Diego Gas & Electric (SDG&E) |
| Main gas utilities | Southern California Gas (SoCalGas), Pacific Gas and Electric, and San Diego Gas & Electric |
| Energy regulator | California Public Utilities Commission |
| Population | About 39.4 million (2024) |
At about 179 grams of CO2e per kilowatt-hour (2023), 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.
Getting your utility data in California
Green Button originated in California through a 2011 CPUC initiative, and PG&E, SCE, and SDG&E all offer Green Button Download My Data and Connect My Data for customer and third-party access (https://www.greenbuttondata.org).
What MartinAI delivers in California
Whether a building is served by Pacific Gas and Electric (PG&E), Southern California Edison (SCE), and San Diego Gas & Electric (SDG&E), 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 California
An audit is where clean data pays for itself. With every bill in California 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 California
California runs a statewide Building Energy Benchmarking Program under AB 802, administered by the California Energy Commission, covering commercial and multifamily buildings 50,000 square feet and larger. Cities including Los Angeles, San Francisco, and San Diego add their own benchmarking or building performance ordinances.

Frequently asked questions
Can MartinAI handle utility bills from California?
Yes. MartinAI reads utility bills across every commodity (electricity, natural gas, water, steam, and fuels) and every layout used by utilities in California, then validates each figure. Local formats and multi-meter accounts are exactly what it is built for.
What is the grid carbon intensity in California?
Grid electricity in California is about 179 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 California?
California runs a statewide Building Energy Benchmarking Program under AB 802, administered by the California Energy Commission, covering commercial and multifamily buildings 50,000 square feet and larger. Cities including Los Angeles, San Francisco, and San Diego add their own benchmarking or building performance ordinances. 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.
