2. JEA (formerly Jacksonville Electric Authority)
Originally a municipal electric authority
In 1997 JEA took over water and sewage for the city
Now we’re just “JEA”. We have about 2300 permanent employees.
Customer base:
405,000 electric
300,000 water
223,000 sewer
Service Territory
900 square miles
Several counties in NE Florida
3. JEA’s Electric System JEA owns and operates three generating plants and all transmission and distribution facilities.
A fourth power plant, the St. Johns River Power Park (SJRPP), is owned jointly by JEA and the Florida Power & Light Company (FPL) and operated by JEA. JEA and FPL are also joint owners of Unit 4 at Georgia Power Company's coal-fired Robert W. Scherer Plant (Plant Scherer), which is located in Macon, Georgia.
JEA produces 3.2 MW from a methane-fueled generating facility at the Girvin Road Landfill.
JEA's net generating capability is 2,361 MW, gross capacity is just under 3,000 MW

12. Meter Data Management System Flow
13. Initial Sample Design Summary Examined Sample Design Population
124 Report & CAIR Rate Name Report
Studied 5 rate classes (Res, GS, GSD, GSLD, Int/Cur)
Designed samples for Res, GS, and split the population for GSD into two subgroups
Consumption Data
Cleaned and organized data (frequency distributions in 50 kWh buckets)
Developed 2-D Stratification (reduce variability)
Delanius Hodges – Produced Breakpoints
For Res and GS, we used a 3x2 design of 6 strata, with 3 winter strata (low, medium, high), and two summer strata (low, high), plus one extreme stratum (very high summer or very high winter or both), producing 7 ‘buckets’
For each subgroup in GSD, we used a 2x2 design, with 2 winter strata (low, high), and two summer strata (low, high), plus one extreme stratum (very high summer or very high winter or both), producing 5 ‘buckets’
14. Residential Sample Implementation
15. GS Sample Implementation
16. GSD Sample Implementation
18. Sample design moving forward We will use the variances and means from the data for August 4th to calculate required sample sizes and allocate sample points for the summer peak
We will use the means and variances for the MV-90 data to calculate the required sample sizes and allocate sample points for the winter peak for GS and GSD, and use judgment for Residential winter peak accuracy
We will carefully consider the implications of the expected percent of meters that can’t deliver interval data
Current sample will be randomly reduced or increased where necessary
We will include interval data from MV-90 customers that are chosen in the sample

23. “Ahas” Originally afraid JEA faced a long, slow, expensive learning curve - Purchasing Energy Use Strategic Service continues to be high value for cost; purchase did not require formal bidding process
Having an NMR system is enabling our LR group to expand beyond traditional LR applications and uses
24. Going Forward Complete COS Sample Design
