| Description: | This Protocol Revision Request (PRR) limits the applicability of the weather responsiveness test to Interval Data Recorder (IDR) Meters. |
| Reason: | Current Protocols require ERCOT to perform a weather responsiveness test on Electric Service Identifiers (ESI IDs) with IDRs and does not differentiate between Advanced Meters and IDR Meters. Performing this test on Advanced Meters has a significant impact on ERCOT System processing times. ERCOT estimates that it would take approximately eight days of system processing time to perform this check on ESI IDs with an Advanced Meter. On Operating Day 6/01/2010, data was being processed for more than 900,000 Advanced Meters. Test runs have shown the data loading portion of this job to be ¾ of a second per ESI ID. · 900,000 ESI IDs * .75 seconds per ESI ID = 675,000 seconds · 24 hours/day * 60 min/hour * 60 sec/min = 86,400 sec/day · 675,000 sec / 86,400 sec/day = 7.8125 days This job running for nearly eight days would impact many core deliverables, including: · Timely completion of core wholesale aggregation and financial Settlements. · Timely loading of Advanced Meter System (AMS) interval data from the market. |
