SCED Validation
RT ICCP
6 mths LMP posting
Data Validation

• EMS integrated with SCED
• Resource Limit Calculator (4 sec)
• State Estimator Solution Data (5 min)
• Transmission Constraint Mngr (5 min)
• SCED reports

• EMS MMS Static Data Synchronization
• EIP upgrade (bug fixes)
• QSEs regression test against real data
• QSEs submit pre-defined offer curves

• Started 8/24

• 6 Months LMP posting

4
Data validation phase will occur during October
QSEs will test against better Registration and
Network Model data

• The current SCED Input Data Validation phase will
  end by 10/04/2007
• QSE Registration data will be uploaded into EMS
  and MMS, 2nd week of October. Data includes
• Data Submitted via RARF (Sept 4 deadline)
• Electrical Bus to load zone map (initial EDS
  dataset)
• Electrical Bus to Hub bus mapping etc. (initial
  EDS dataset)
• QSEs are required to regression test SCED against
  real data
• QSEs submit pre-defined offer curves to SCED

SCED will be integrated with EMS by 11/01/2007

• EMS to MMS integration for SCED
• SCADA Inputs
• GTBD
• Resource Limit Calculator
• State Estimator Solution
• Transmission Constraint Manager
• Currently planning to publish the following
  reports
• SCED Inputs
• Status of breakers and switches
• Transmission flows and voltages
• Transformer flows, voltages and tap position
• Voltage schedules
• 15 min average of Loads on Electrical Buses
• SCED Outputs
• LMPs on each resource node
• SPPs on hub and load zone
• Shadow Prices

Bottom line With this deployment to EDS we can
start calculating LMPs using real-time system
conditions

Status of key activities to meet SCED objectives
7
EDS 3 Release 5 Testing Objectives

• EDS 3
• Release 5 Trial Operation of SCED, 6 month
  LMP posting (SCED MP Handbook)
• SCED 1 Input Data Submittal and Validation
  (8/24 to 10/4)
• SCED 2 SCED Execution (Controlled EMS Input)
• SCED 3 Integrated SCED Execution (RT ICCP)
  (11/1)
• SCED 4 Six Month LMP Posting (mid-January 08)
• Release 6 Trial Operation of LFC, ACE
• Release 7 Trial Operation of CRR, sample
  Settlement Statements

• Provide a SCED environment for Market Participant
  EDS Activities
• Both user Interface and machine-to-machine
• Verify QSEs ability to use Web Services to
  create, change, cancel, and query three part
  offers, COP, output schedules and inc/dec
• Verify QSEs understanding of SCED input
  validation rules

EDS 3 SCED Input Data Submittal and Validation
Testing Status
Registration for test windows is complete,
connectivity tests and Web Service submissions
are underway. Status is tracking to plan.
9
Support Windows by Week
We appreciate the QSEs that signed up for early
test windows. Effort increases as we progress so
we all need to work together to stay on track.
10
Lessons Learned

• Keep Sandbox current / ahead of EDS environment
• We are working to remedy this
• Connectivity Test (Ping)
• Work with your network group to enable in/out
  traffic on network prior to test
• During test have network, system admin available
• Requires system access during the test
• Support Window
• Prior to test submit sample files to ERCOT for
  validation
• Have scenarios ready so execution of scripted
  tests are more efficient
• Non-business hour support
• Please prearrange (eds3_at_ercot.com) so we can
  determine if it is possible

Testing Schedule (8/24 to 10/4)
Mondays Fridays are reserved for status calls.
We had poor attendance on 8/27 (50). To stay
informed please have a representative attend.

EDS 3 Known Issues

• Market Update Calls are being held Monday and
  Friday
• Summary of known issues
• Notifications are not being sent
• Query Output Schedule not working
• If submitting an Output Schedule for a partial
  day MP is required to first submit a TPO for the
  other hours
• Resources for defect information
• Sandbox Environment Readiness Center \ sandbox \
  documents \ Sandbox Web Services Defects
• EDS Environment Readiness Center \ EDS 3 \
  Documents \ Known Issues

Majority of the functionality is available and we
are working toward completing internal testing
and releasing corrections

EDS 3 Release 5 Testing Deliverables
These will be delivered through the course of EDS
3 Release 5 (8/24 to June 08)

EDS 3 Ongoing Process

• What will happen next?
• 15 hour days
• Sleepless nights
• Happy MPs

Document Reviews - Plan
SCED Phase 2 moving away from scripted tests
and use it for upgrades, data sync, test offer
curve submissions
