First round complete with challenges
Stakeholders will have more testing opportunity
Peak users will receive access this year
Stakeholder entities will receive training and access during Q1 2016
Training plan includes classes, webinars, CBTs

Will have sandbox to create ECC Elements
Balancing Authorities
Will be involved with e-Tag curtailments and ACE changes
Transmission Service Providers
Supplement On/Off Path transaction designation

5. Next Phases Future Time Situational Awareness webSAS Integration
3 hours into the future
Needs additional inputs
webSAS Integration
Moves from webTag to webIntegrity
Benefits over current engine
Expanded Curtailment Methodology

6. PSE Access
Peak has been evaluating PSE access across all Peak-provided tools
Question of what access will reside in ECC for webSAS and curtailment expansion
Peak has determined that webSAS module will retain current PSE access rights
Need to determine process of identifying PSEs

7. Timing of Future Time SA and webSAS
Peak is weighing what is next phase
Future Time SA:
Expands current time and is more logical
Forecast data quality is an issue
webSAS Integration:
Allows buy-in of tool with stakeholders
Will need parallel ops for UFAS verification
