SPP will hold a two-day review session for the Attachment Z2 credit-settlement system June 28-29 at its Little Rock headquarters. The session will run 9 a.m. to 4:30 p.m. each day.

The review session was initially planned for late May, but conflicts with a number of stakeholder meetings pushed the date back.

The Z2 settlement system is being used to help resolve years of incorrect credits for transmission upgrades; the Board of Directors last month approved a payment plan that will begin in November. (See “Board Approves Z2 Level Payment Plan,” SPP Board of Directors Briefs.)

Staff said attendees will gain an understanding of how the settlement system was designed and built and how its calculations are performed.

SPP is asking attendees to complete the Z2 online course on SPP’s Learning Center, review a Z2 white paper and sign a nondisclosure agreement, which will be sent after registering for the review session.
