Doing Business in a New Climate

Below is a table of California utilities who are California Registry members.  As part of their reporting requirements, these utilities must provide an efficiency metric of lbs. CO2/MWH for the electricity delivered to their customers.  This metric is referred to as a utility-specific electricity delivery metric.  These metrics provide the most accurate picture available of the electricity that you actually consume each year.

Utility Name 2008 Emission Factor
lbs/MWh lbs/KWh
Austin Energy 1,083.07 1.08307
California Department of Water Resources 716.14 0.72
City of Vernon 810.38 0.81038
Imperial Irrigation District 1,270.90 1.27090
Martinez Cogen Ltd. Partnership 945.27 0.94527
PG&E 641.35 0.64
Sacramento Municipal Utility District 632.43 0.63243
San Diego Gas & Electric 739.05 0.73905
Seattle City Light 28.99 0.02899
Sierra Pacific Resources dba NV Energy 1,328.16 1.32816
Turlock Irrigation District 790 0.79000

A good way of double-checking the kWh you report to the California Registry is to compare your monthly electric bills with an annual statement of usage provided by your utility provider. Here are some links from California utilities where you may be able to find useful information:




PG&E customers may log onto PG&E’s website to access two year’s worth of annual electricity consumption utilizing their account number.


Local governments may contact for municipality information.
