Check this little piece of information hidden deep on the PG&E website... http://www.pge.com/myhome/customerservice/energychoice/coregasaggregation/
PG&E's Core Gas Aggregation Service is an optional program that allows you to purchase gas for your home or business directly from third-party gas suppliers, also known as Core Transport Agents (CTAs). Through this program, PG&E will continue to read your meter, and to transport and deliver gas to your home or business with the same high level of reliability and service that we provide to all of our customers.
PG&E requires new CTAs to complete a certification process, which entails meeting credit and technical requirements, before they are eligible to enroll customers. If PG&E terminates a CTA's certification due to a failure to maintain PG&E's certification requirements, or if a CTA goes out of business, a CTA's customers would continue to receive uninterrupted gas service directly from PG&E.
Basically - look at the list here - http://www.pge.com/myhome/customerservice/energychoice/coregasaggregation/coretransportagents/index.shtml
- find an aggregator that serves your area - I picked Tiger Natural Gas - and pretty soon you'll be saving >15% on your gas bill with no changes to your service or your billing... it's so simple it's silly...
Try it. At first I thought this was a scam when I got the call from Tiger, but it's something the government forces PG&E to do... and they probably just hide it real well so no one will find out
