What Information is Available• Cost information for a small number of rate

plans, by TDU service area and REP• Plans identified by name, which may give some

indication of type of plan• All-in rate, includes delivery charges• Plans appear to be selected to provide cost

comparisons over long periods• Separate table on PUC website provides

unbundled delivery rates• Lag in posting of information

Using PUC Rate Information to Calculate G

• May need broader set of rate plans• Need to refer to other sources for key

plan details (EFL or Terms and Conditions)

• Need to subtract delivery rates calculated from different web page

• Is lag in posting information a concern?
