  1. Profiling Working Group Update to RMS June 5th, 2018 Sheri Wiegand (TXU) – Chair Sam Pak (Oncor) – Vice-Chair

  2. 2018 Annual Validation 814_20s are underway . TDSPs have begun to send on meter cycle dates.

  3. Default Profiles – BUS • BUSINESS ESIs current default profile is BUSMED • Current profile distribution of NIDR meters With the Sharyland/Oncor transition, the larger population of BUSMEDLF ESIs represented the default profiles for the new Oncor ESIs created. AMS deployment is expected to complete by end of 2018.

  4. Default Profiles – BUS • BUSINESS NIDR Changes for 2018 Annual Validation The volume of MWHs to move from MED to HI profiles and MED to LO profiles is nearly the same.

  5. Proposed LPGRR & NPRR Process Revisions • Proposed revisions to Annual Validation process… • Business ESIs reviewed annually • Residential ESIs reviewed every 3 years (all TDSPs to process same year) • Proposed revision to the Business default profile from BUSMED to BUSLO The NPRR and LPGRR will be presented at the July RMS meeting and posted by mid June for review.

  6. 2017 UFE Analysis Randy Roberts May 2018 PWG Meeting

  7. UFE Basics 1 • UFE (Unaccounted For Energy) is computed as follows: UFE = Generation – (Load + Losses) • Negative UFE indicates load/losses are overestimated Sources of UFE include: ■ Generation Measurement Errors ■ DC Tie Inadvertent Energy ■ Load - Missing/Erroneous Usage Data - Backcast Profile Error - Load Profile ID Assignment Error - Theft ■ Losses - Model Error - Loss Calculation Error - Loss Code Assignment Error May 2018 PWG Meeting

  8. UFE Losses: Transmission & Distribution Interval Data Energy Usage Profiled Energy Usage Non-Metered Accounts UFE Basics 2 GAP - - - - - - > Net Generation for Settlement Interval Net Generation Compared to Load Buildup May 2018 PWG Meeting

  9. Data Required Per Protocol Section 11.6.2 May 2018 PWG Meeting

  10. Average Daily % UFE (sorted low to high) May 2018 PWG Meeting

  11. UFE Monthly MWH May 2018 PWG Meeting

  12. UFE Monthly Cost May 2018 PWG Meeting

  13. Historical Yearly Values May 2018 PWG Meeting

  14. Historical UFE Cost, MWH, and Average MCPE May 2018 PWG Meeting

  15. 2017 Transmission Loss vs. UFE May 2018 PWG Meeting

  16. 2018/2019 Transmission Losses (Actual & Forecasted) SPECIAL NOTE See 3/23/2017 TAC Meeting – Key Documents – Item 11. ERCOT Reports – Transmission Loss Factors (TAC March 2017).pptx for additional details on higher than normal TLFs May 2018 PWG Meeting
