  1. Proposal: RMS/COPS Workshop IDR Threshold Requirement RMS: September 9, 2014 COPS: September 10, 2014

  2. IDR Required Threshold • Protocol Section 2 Definitions and Acronyms: • Interval Data Recorder (IDR) • A metering device that is capable of recording energy in each Settlement Interval under Section 9, Settlement and Billing, and Section 10, Metering. • Interval Data Recorder (IDR) Meter • An IDR where the ESI ID is required to be assigned a BUSIDRRQ Load Profile Type code and data is submitted in accordance with Section 10.3.3.3, Submission of Settlement Quality Meter Data to ERCOT. • Interval Data Recorder (IDR) Meter Mandatory Installation Requirements • The kW (kVA) level at which the installation of an IDR Meter is required for Settlement purposes as set forth in Section 18.6.1, Interval Data Recorder Meter Mandatory Installation Requirements.

  3. IDR Required Threshold • Protocol Section 10.3.3.3 • Submission of Settlement Quality Meter Data to ERCOT (1) Settlement Quality Meter Data shall be submitted to ERCOT on a periodic cycle, but no later than monthly: (a) For provisioned Advanced Meters, Settlement Quality Meter Data will be submitted using an ERCOT specified file format for the interval data only, which will be used for Settlement. (i) The monthly non-interval total consumption and demand (if applicable) values for these ESI IDs shall be provided to ERCOT and Load Serving Entities (LSEs) using the appropriate Texas Standard Electronic Transactions (TX SETs) in order to: (A) Effectuate the registration transactions outlined in Section 15, Customer Registration; and (B) Determine if a Premise has become subject to the IDR Meter Mandatory Installation Requirements. (ii) These non-interval total consumption and demand values will not be used for Settlement. (b) For all other meters, Settlement Quality Meter Data will be submitted using the appropriate TX SET.

  4. IDR Required Threshold • Protocol Sections 18.6 • Installation and Use of Interval Data Recorder Meters: • 18.6.1 Interval Data Recorder Meter Mandatory Installation Requirements (1) Interval Data Recorder (IDR) Meters are required and shall be installed and utilized for Settlement of Premises having either: • A peak Demand greater than 700 kW (or 700 kVA in CenterPoint Energy’s service territory); or (b) Service provided at transmission voltage (above 60 kV). (2) For the IDR Meter installation process, refer to the Retail Market Guide Section 7.13.2.2, Mandatory Interval Data Recorder Installation Process.

  5. Should the IDR Required Threshold Be Revisited? • Reasons: • Per the ERCOT Board Report dated 8/5/14 there are 6.6M Advanced Metering System (AMS) Electric Service Identifier (ESIID)s included in settlement as of June 2014. • Note:Several years ago the market approved lowering the IDR required threshold from 1000 kW/kVA to 700 kW/kVA to increase the number of premises ERCOT settled using 15 minute interval data received from the TDSPs. • For AMS meters, TDSPs are providing daily 15-minute interval data through LSE Files instead of an TX SET 867_03 Monthly Usage transaction containing 15-minute interval data for traditional IDR meters. • For AMS meters, daily15-minute interval data provided to ERCOT by the TDSPs through LSE files allows Customer’s usage data to be available for initial settlements instead of only being available for Final and True-up through monthly 867_03 TX SET transactions. • Per protocols TDSPs are required to provide an 867_03 Monthly Usage transaction for ERCOT settlements of Load Profile Types of BUSIDRRQ and for an AMS meter TDSPs would no longer provide daily-15 minute interval data via LSE files for ERCOT settlements. • Note: This may in some cases require replacing the current AMS meter at the premise with a traditional IDR because of TDSPs’ system limitations and their MDM (AMS) vs. MV90 (IDR) architecture.
