ERCOT Planning Go-Live Update
Jay TeixeiraManager, Seasonal Planning

ERCOT Concerns regarding Planning Go-Live
• Topology Processor is in production for CRR– Data, such as connectivity node groups (CNG) must be
maintained by ERCOT and TSPs– Equipment IDs and Circuit IDs for all equipment must be
populated and unique and are dependent on correct CNG definition
• TSPs will need to commit to Go-Live barring unforeseen major problems– SCR needs commitment
• No reflection on current TSP efforts, but TSPs will need to commit necessary resources to complete testing in an expeditious manner– 2012 Base Case testing– SCR testing, testing timelines will be tight– Building base cases while testing system has stressed workload

ERCOT Concerns regarding Planning Go-Live
• June PLWG discussion on no longer creating Data Set A cases because TSPs do not use them
• Delay affects Data Set A cases which where shown to be mainly used by ERCOT– Big effect on Near Term congestion analysis and studies to
support ERCOT Operations– Studies simulate planned outages, manual process to map to
SSWG cases

Data Set A Uses from June PLWG meeting
ERCOT Use DS A Case Used
Determining Flat load for Near Term congestion and 5 year plan cases
Uses all 8 cases for range of load level.
SPS Reviews Can use any of all 8 cases depending on SPS under study and time frame
RMR Analysis Can use any of all 8 cases depending on RMR unit under study and time frame
Transmission Loss Factor Calculations Uses generation, load, losses from all 8 cases
Near term congestion analysis Uses summer peak topology
ERCOT Operations requested studies Can use any of all 8 cases
Dynamic Data Set (wind and no wind) Currently use summer peak, DWG proposal to use peak and off-peak case
Stability Screening Studies (Dynamic and Voltage)
PV and TS for summer, PV for winter peak and TS for winter off-peak
NERC Compliance Studies Summer peak and one off-peak
Voltage Profile Studies Peak(Sum, Win) and Off peak (Spg, Fal) cases

• SSWG commitment to Go-Live barring unforeseen major problems
• TSPs commitment to provide resources to complete testing in an expeditious manner
• Decide Model on Demand Separated System Go-Live for 2012 Data Set A case build first
• Then decide for 2012 Data Set A whether to move to Topology Processor/Model on Demand Integrated System

Protocol 3.10.2 – Which Five Years?
ROS November 11, 2010
3.10.2 Annual Planning Model (1)For each of the next five years, ERCOT shall develop models for annual planning purposes that contain, as much as practicable, information consistent with the Network Operations Model. The “Annual Planning Model” for each of the next five years is a model of the ERCOT power system (created, approved, posted, and updated regularly by ERCOT) as it is expected to operate during peak Load conditions for the corresponding future year.(2).(3).(4).
(5)ERCOT shall coordinate updates to the Annual Planning Model with the Network Operations Model to ensure consistency of data within and between the Annual Planning Model and Network Operations Model to the extent practicable.
