1. VEA Modeling, Data Responsibility, and Coordination

2. BAA VEA

3. Moved from NV Energy (Nevada) BAA to CAISO’s BAA in 2012, remaining physically connected to NV Energy’s transmission network VEA owns Transmission Equipment and provides service to Loads New Solar PV Generator (~15MW) forecasted to go in service by early 2016 Bob SS, Connecting to Eldorado, forecasted to go in service by early 2018

4. BAA Tie-Lines BAA Meters: “18022 NWEST 230.00” – “DESERT VIEW 230.00” “18003 AMARGOSA 230.00” – “AMARGOSA 138.00” “19012 MEAD S 230.00” – “PAHRUMP 230.00” Future: Eldorado (Bob SS) “MERCRYSW 138.00” – “JACKASSF 138.00 ” “MERCRYSW 138.00” – “INNOVATION 138.00 ” “MERCRYSW 138.00” – “MERC-DIST 138.00 ” VEA Mead (14) Eldorado (24) Amargosa (18) Northwest (18) Mercury (18)

5. VEA WECC Modeling 31 Bus Models 39 Load Models 2 Generator Models (Early 2016) Ties to NVE, Arizona, & Southern California (2018) Current WECC Process: VEA in Area 18, Zones 890 & 891 Data flow: VEA -> NVE -> WECC Current WECC Power Scheduling Process: Southern California (Kevin Brooks) to WAPA (Mohsin Shabbir) to NV Energy (Ben Hutchins) to VEA(Dave Larsen) Real Scheduling does not match current process!

6. Current Process (Pros/Cons) Pros: None Cons: Leaving VEA in A18 doesn’t line up with Balancing Area splits Data & Facility Ownership splits Planning Coordinator Functions Operational Responsibility Modeling VEA in A18 doesn’t match the actual Scheduling process Scheduling is more complicated than it needs to be VEA’s Planning is done between VEA, Navigant (consultants), and CAISO. NV Energy is not involved in the planning process, but is currently helping maintain the models and submitting them. https://www.caiso.com/Documents/ISOGeneratorInterconnection Queue.pdf https://www.caiso.com/Documents/ISOGeneratorInterconnection Queue.pdf Complicated data responsibilities for NERC compliance purposes

7. Proposed Process Assign VEA a new area (Add to the DPM) Area #: 89 Zone #: 890-891 Bus #: 89,000 – 89,999 Owner: 25 Swing Bus: 189201 WDAT1-1A 24.94 (Vista PV) Update WECC Master Tie-Line File VEA will submit directly to WECC Dave Larsen (Navigant, VEA Consultant) Joseph Meier (Navigant, VEA Consultant) Kristin Mettke (VEA) NV Energy will no longer schedule interchanges for VEA in WECC submittals, it will be coordinated with VEA & SCE

8. Proposed Process (Pros/Cons) Pros: Clear Data Ownership Clear Planning Coordinator Definitions Clear Scheduling for WECC Case Builds Clear Compliance Responsibilities Proposed modeling matches real-world BAA boundaries WECC will be receiving the data directly from the facility owner Cons: DPM Needs an Update Tie-Line File Needs an Update Notes: Ben Hutchins will volunteer to make the initial Case changes & Tie- Line File, and assist in transferring data responsibilities to VEA/Navigant/CAISO

9. Timeline DPM Updates & Approval: March 17 th, 2016 Area, Zone, Bus, Owner Changes: April 1 st, 2016 Any WECC Data Request after April 1 st will include this change. The change will not be made to review cases, only new Case Data Requests.
