CCTA process
Transmission topology  C Case 2026
Regional Planning Groups  Key entities
Mindful of RPGs’ complying with FERC Order 1000 and their criteria
Not influenced by FERC Order 1000 criteria
Cost-allocation is not the focus for selection
RPCG – Ideal forum for such feedback

8. 5 criteria used for review
Criteria 1: Regional Significance
Based on Voltage:
500 kV and above
200 kV or greater if “backbone”1 facility
Criteria 2: Construction Status
Is the project currently under construction?
Criteria 3: Financial Indicators
Financial questions added to project survey to indicate if the project has financial commitment
Criteria 4: Implementation Status Indicators
Environmental Impact Status (EIS – if required) questions added to survey
Criteria 5: Project Dependency
Is this project dependent upon another transmission project to be completed and used for its intended purpose? If so, did the dependent project pass the CCTA criteria?
1 Backbone transmissions are facilities that provide network connectivity, typically kV

9. CCTA Process Demo: “Everett – Madison Transmission Project”
Similar table to be created for all potential transmission projects
This is the type of table we’d create for all potential candidates
Highlighted fields will be considered in CCTA criteria/flow
