    Q. Why is the Power Content Label no longer published quarterly?
    A. On October 11, 2009, the Governor signed Assembly Bill 162 which made changes to how electric utilities report their PCL, including changing the reporting requirements from quarterly to annually. Also, posting the PCL on the web (instead of a sending a print mailing) fulfills publishing requirements.
