7. NERC RAS Definition
NERC BOT approved the proposed new RAS definition in December and filed it with FERC on February 3.
Don’t let the 3698-page filing intimidate you. It includes all the comments, responses, and standards revisions.
The actual definition is a little over one page (shorter than BES!)

8. NERC RAS Definition There is a broad general RAS definition, but . . .
. . . many more exceptions than the old SPS/RAS definition.
. . . and retire SPS.

9. NERC RAS Standards
The RAS drafting team is in the middle of the first draft, with tentative posting in May.

10. NERC RAS Standards Major proposed items (new PRC-012-2):
Reviews required for new and modified RAS
Reviewing entity is the RC
5 year evaluations by TP—any deficiencies require a CAP
Owner must review all RAS operations for correctness—any functional modifications require a CAP
Any RAS CAP must be implemented
RAS database maintained by RC
RAS owners must share modelling data with other entities that have a reliability need

11. NERC RAS Standards
Maintenance and testing (maybe a revised PRC-005-x):
Add RAS controllers
Pretty much all other components of RAS are already in PRC-005

12. April 6-8, 2015, Salt Lake City, UT (less than two weeks away!)
Next RASRS Meeting
April 6-8, 2015, Salt Lake City, UT (less than two weeks away!)
