LIP A Data Request 58
LIP A Data Request 58
Because the Company appears to be proposing the usage of the average of 5 years
of irgation data for the Irrgation customers, please provide the five year average
data (similar to that provided in the response to LIP A Data Request 3 for the
Irrgation customers) for Schedules 1,36,6, and 23. Please describe the method
used and all calculations that were used to tae the individua load research data
for each sample customer in order to develop the average for the rate schedule
over the five years.
Response to lIP A Data Request 58
Please refer to Attachment lIP A 58.
Individual customer data is not weighted and must first have weights applied
before stratu averages can be determined. Strta weight factors for each load
research saple can be found in the header of Attachments lIP A 57 -1 though
IIPA 57 -5.
Each contrbuting year of the 5- year average is equa to the sum of the weighted
stratu averages for any given time interval.
The 5-year average is based upon a normalized year, rather tha a simple
averaging of the system peak. Each of the contrbuting years (2005-2009) was
adjusted to fit the 2009 day-of-the-week profie. For intance, Janua 1,2009
occured on a Thurday. The closest correspondig Thursday to Janua 1 in the
2005 data was Janua 6th. The 2005 data was shifted 5 days (+ 4 years) to align
with the 2009 data. In 2007, the closest correspondig Thuray to Janua 1 was
Janua 4. The data was shifted 3 days (+ 2 years). Once ths alignent of all th
contrbutig years was complete, the years are averaged together to obta a
normalized representation for the year 2009.
