FW: FYI--Application of SCE Load Profiles

The proper application of Load Profiles was identified as a gap in DQI 
workshop;  see the transaction matrix under Processing of Settlement 
Ready data.   Edison has developed protocols for the application on 
Load Profiles and has provided this information at the ESP open house 
and recently via a message from Carl Silsbee.

I am proving this information as an FYI for the group.

Subject: Availability of Dynamic Load Profiles for Review

Since early April, SCE has been posting sample dynamic load profiles 
(DLPs) for residential, GS-1 and GS-2 customer groups to our website, 
www.edisonx.com/rci. (You will need to follow the hyperlinks from this 
main page).  The process appears to be working well. You can access 
these DLPs for review and testing at this time. The DLP files contain 
data beginning with transaction day April 1, 1998.  Although the DLPs 
are based on real data from our load research sample meters, they are 
NOT for use in PX/SC and ISO settlement at this time.  ESPs should 
continue to use the static load profiles we have previously provided 
for these customer groups through transaction day May 17th.

ESPs with questions regarding the posted DLPs during the testing phase 
through May 17th should send e-mail to Cyrus Sorooshian at 
soroosc@sce.com.  Cyrus is responsible for preparation of the DLPs 
which we are posting.  Once we begin posting the DLPs for PX/SC and 
ISO settlement, ESPs should contact SCE's ESP Services group directly 
with questions or if there appears to be an error in the posted data. 
 This will allow us to maintain a formal record of your inquiry and 
insure adequate follow-through.  A courtesy copy or e-mail note to 
Cyrus regarding any inquiry directed to ESP Services would be 
appreciated.

At an ESP open house, SCE distributed a protocol which sets forth the 
specific procedures which ESPs (or their SCs) should use for 
determining hourly usage for customers with cumulative meters.  A copy 
of this protocol is attached for your reference.  ESPs with questions 
regarding implementation of this protocol should contact SCE's ESP 
Services group.

 
Currently, we are posting data with approximately a three-day lag. 
 That is, data for a Monday (24 hours ending at midnight), is being 
posted via an overnight batch processing "run" which is submitted 
during the day on Thursday, and available on Thursday PM/Friday AM. 
 Once we move to production mode, the posting time will be speeded up 
to 62 hours.  That is, our objective will be to make Monday's data 
available between 2:00 PM and 3:00 PM on Thursday.  We are not 
planning to process load profiles over the weekend.  That is, Friday 
data will be posted the following Wednesday (along with Saturday and 
Sunday data).  I realize that at a workshop last February, we 
announced a goal of 48 hours for posting DLP data.  If the schedule we 
are now planning to follow causes any ESPs a significant hardship, 
please contact Robert Ramirez, who is responsible for SCE's load 
profiling implementation.  Robert can be reached via e-mail at 
ramirer@sce.com.  We would like to accommodate reasonable concerns for 
timeliness of data flow; but of course we don't want to add 
unnecessary costs or increase the potential for processing errors.

Since load profiling was first raised as a market mechanism issue in 
the original 1995 Direct Access Working Groups, it has been one of the 
more contentious areas of direct access implementation, resulting in 
seemingly endless, and sometime fractious discussions.  I appreciate 
everyone's endurance and good spirits in getting us to where we are 
today.
