Real-Time Data Submission

● Real-time data will be submitted via ICCP.

● Currently ICCP links are up and exchanging real-time data with most of the BAs and a few TOPs.

● As WECC identifies missing or needed real-time data, we will make requests for that data.

● Currently ~62,000 real-time data points currently in WECC SCADA. 3

4

Non Real Time Data Submission

● Hourly Load Forecast

● Daily Peak Load Forecast

● Unit Commitment

● Scheduled Interchange

● Operating Reserves

How the data will be submitted

● Using the Electric Industry Data Exchange method (EIDE)

● WECC will make available a “putSchedule” EIDE method via an external facing web service. The “putSchedule” meets all the needs of schedule data submission to WECC.

5

Hourly Load Forecast Submission

● Submit a rolling 7 day forecast for your BA. When to send?

Submit a forecast at least on a daily basis. You can submit as many changes during the day for forecast updates.

How to send?

Submit to WECC’s external facing Web Service that exposes the putSchedule method. Client certificates will be used for authentication over standard https.

What to send?

WECC needs an hourly load value for your BA. The values should always start on hour 00 of the current day of submission. There should be a total of 168 hours of submission (24 hours X 7 days). If you do not have hourly values stretching the entire 7 day period, please fill in the remainder of the hours with the last known day’s peak load value. All times are PST 24 hour clock. 6

Operating Reserves

● Required Reserve data for submission is still being defined by RC’s. Updates will be sent shortly.

15

Timeline for Data Submission

● The WECC Web Service will be made available starting July 28th for testing purposes.

● The Web Service will go into a production state the week of October 1st 2008. Please have all testing completed and a production feed in place at that time.

16

Equipment Outage Schedules

● WECC will be using the COS (Coordinated Outage Scheduler) from Equinox.

● Outages can be submitted in two ways: Manually - Web interface with login for each outage

submitting BA will be provided. WECC is in the process of populating COS with equipment information from each BA.

Automated – Work with Equinox to tie your outage scheduling software to the COS. Equinox has already interfaced many common outage scheduling tools.

17

ICCP Node Additions

● Currently WECC has a single node for the Vancouver and Loveland sites. We will be adding 2 additional nodes to become backups for the single nodes at each site.

● The Vancouver node is 42.190. We will be adding 42.191

● The Loveland node is 43.90. We will be adding 43.91

● Please have your ICCP staff add these additional nodes into your system.

18

ICCP Data Additions

● If you have not already done so please make available: Instantaneous Load Actual Interchange Instantaneous ACE Frequency at one location MW Reserve available in 10 minutes

WECC will be placing their Time Error Correction points online when our time systems are configured in preparation for taking over the timekeeping role (end of year).

19

WECC Next Steps

● Validating ICCP measurements and model WECC staff will be contacting WECC BAs and TOPs to

coordinate a checkout of the new west-wide system model. We will be validating measurement availability, model accuracy, and SE solution results.

● Ratings Implementation Many of the WSM equipment do not appear to have correct

ratings. WECC also does not have seasonal ratings. WECC will work with the BAs and TOPs to correct these issues.
