1. Nodal ICCP Availability Report Ken McIntyre

2. Presentation Recap ICCP Availability Requirement ERCOT Reports to be posted

3. Recap ICCP Availability Requirement ICCP links must achieve a monthly availability of ninety-eight (98%) percent, excluding approved planned outages. Availability will be measured based on end-to-end connectivity of the communications path and the passing of Real-Time data. A link will be considered as available when at least eighty-five (85%) percent of the data defined on that link is successfully transferred to ERCOT with a valid or manual quality code.

4. Recap ICCP Availability Requirement ERCOT has ability to enter planned telemetry outage times Need to develop process for TSP/QSE to notify ERCOT of telemetry outages ERCOT to apply better point filter ERCOT to develop ICCP only report

5. Reports to be posted ERCOT will ‘approve’ and post three reports to address the ‘intent’ of this requirement The three reports will provide data for NDSWG to help support a telemetry standard revision Three supporting reports are: 1.Individual Point Availability report (existing) 2.85% availability for 98% of time report (existing) 3.ICCP Link Up/Down report (new)

6. Points for Moving Forward Review this requirement as part of the NOGRR025 review process Use the data/reports ERCOT is providing as a starting point Avoid adding or changing the requirements that would cause major system change efforts (cost) ERCOT still investigating alternate measurement for this requirement (system change/cost)
