January 18, 20131
Topics to be covered today
• What was done and not done in the 2006 study
• What methodology was used
• Findings of the 2006 USL study
• Answer any questions
2
Background about 2006 study
• A USL load data study was done as part of the work required in EB-2005-0317
• The study done in 2006 focused on certain types of unmetered scattered loads (USL)
• For street lighting and sentinel lights, the Board accepted the recommendations from RP-2003-0228 Working Group using a “deemed” load profile

Methodology used in 2006 load profile study
Street Lighting and Sentinel Lights
•The hourly load data is provided by LDC
•Get normalized “Street Lighting” data by dividing each hourly data by the sum of all “Street Lighting” hourly data
•Same for Sentinel lights
8
Methodology used in 2006 load profile study
Photo Sensitive USL
For photo-sensitive loads, street lighting’s load shape was used as the base. The load shape was scaled such that total usage of each month would add up to monthly GWh provided by each LDC

Non Weather-Sensitive
Methodology used in 2006 load profile study
A generic weather-normalized load shape was developed by using data provided by Rogers. The usage per battery matt, number of battery matts, temperature and seasonal patterns were taken into consideration

USL Load Data Study in 2006
- Participation: 10 LDCs provided data
55 cable TV power supplies
2 telephone booths
4 pipeline cathodic protection devices
3 billboards
- Data collection: duration of data ranged from one day to 3
months
- Information from Rogers: detailed information on usage
and battery heater mats
12
USL Load Data Study Findings in 2006
Cable TV power supplies
- The cable loads were very flat
- Energy consumption for cable TV equipment varied substantially
- Nameplate information varied by equipment and the information was difficult to obtain
13
USL Load Data Study Findings in 2006
Battery Heater Mats
- Data provided by Rogers showed significant correlation with hourly weather
- Weather normalized load shape was generated
- Sample used for analysis was limited to selected areas
14
USL Load Data Study Findings in 2006
Other USL Loads
- The loads were relatively flat
- Findings may not be statistically significant due to the limited sample size
