Energy Data and Utility Bill Audit in San Diego
Utility data delivery, bill audit, and emissions reporting for San Diego, California. From messy bills to structured, validated records you can trust.
Managing energy in San Diego 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 city in the United States, San Diego has its own utilities, regulator, and reporting rules, and this page covers what that means for your data.
The energy picture in San Diego
| 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 |
San Diego draws from the California grid, so its electricity carbon intensity reflects that grid. 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.

What MartinAI delivers in San Diego
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, 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 San Diego
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 San Diego 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 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 San Diego and 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 San Diego?
Grid electricity in San Diego, which sits on the California grid, 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.
