Who Does TEPPC Serve?
Transmission Expansion Planning
• Key Question: How might the transmission grid in the Western Interconnection need to change in 10 or 20 years to meet load reliably with available resources?

Environmental Data Task Force
Environmental Data Task Force (EDTF)• Formed in June, 2010• Includes representation by broad
stakeholders• Provides input to transmission expansion
planning process
Primary EDTF Products
• Available• Reviewed for Quality• Relevant to Transmission Planning
Preferred Data Sets
• Four Risk Levels• Low Risk (1) to Exclusion Area (4)
Risk Classification System
• Compares relative risks of transmission alternatives• Alternatives identified in long-term study cases• Available for use outside of WECC
Comparison Methodology
• Considers “environmental risk contours”• Also considers cultural risks• Considers capital costs of “bending lines”
Review of Study Case Results
Environmental/Cultural Data (Samples)

Sensitive Species Areas
Tribal Lands
Conservation Areas
Wilderness Areas

Risk Classification
Category 4• Exclusion Areas
Category 3• High Risk
Category 2• Low-to-moderate risk
Category 1• Lowest Risk

Benefits of Environmental Data
• Decrease cost and conflict• Avoid delays
Use of Data at Planning Stage
• Avoid or mitigate risks at planning levelEnsure Data

• Use by federal/state/provincial/ regional entitiesPublic Availability

W E S T E R N E L E C T R I C I T Y C O O R D I N A T I N G C OU N C I L
Example of Use: WECC Long-Term Planning Tool
• Creates transmission expansion options based on study case inputs– Loads, resource costs, fuel prices, carbon cost
• Options are “point-to-point”– Need to “bend the lines”

Environmental Risk Classes 1-4
• Blue line connects endpoints
• Darker areas = higher risk category

LTPT With Environmental Overlay
• Semi-transparent EDTF overlay on terrain map
• Semi-transparent corridor over EDTF and terrain maps

Cultural Resource Data
• Cultural resource data differs from environmental resource data– Location of cultural resources is highly sensitive
• Using cultural resource data in transmission planning requires a different approach– Relative density of known cultural sites– Whether and when a location has been surveyed
19
W E S T E R N E L E C T R I C I T Y C O O R D I N A T I N G C OU N C I L
Approach to Applying Cultural Data
1. Collect SHPO Data• Known Sites (can be points,
lines, and/or polygons)• Surveyed (inventoried)
Areas
2. Overlay the standard EDTF grid cell (0.5 km2)
20
W E S T E R N E L E C T R I C I T Y C O O R D I N A T I N G C OU N C I L
Approach to Applying Cultural Data
• Grid cells that contain any sites are marked as cultural resource grid cell
• Identify the number of grid cells in the “neighborhood” (directly adjacent) to each cell
• Range of 0 to 9

W E S T E R N E L E C T R I C I T Y C O O R D I N A T I N G C OU N C I L
Cultural Resource Data ApproachDesignation Name Description
Category A Lowest Cultural Resource Risk or Uncertainty
“Low Density” of sites that have been surveyed in the last 10 years
Category B Moderate Cultural Resource Risk or Uncertainty
Areas where a “Low Density” of sites has been identified, but where the survey information is older (>10 years)
Category C High Cultural Resource Risk or Uncertainty
Areas with a “Moderate Site Density” (regardless of when or if a survey has been conducted in the area).
Category D Highest Cultural Resource Risk or Uncertainty
Areas with a “High Site Density” regardless of when or if a survey has been conducted in the area.
Category E Unknown Cultural Resource Risk or Uncertainty
Areas with a zero site density and where no surveys have been conducted.

Cultural Resources
• Five states currently committed to sharing cultural resource data
• Others in negotiations

Ocean and Coastal Data
• Why is WECC concerned with ocean and coastal data?– Increasing off-shore energy development (wind off
of Oregon)– Developmental projects (wave energy off of the
Pacific Coast)– Increasing interest in offshore transmission—
California project

Ocean and Coastal Data ExamplesCategory Description Examples
1 Lowest Risk
2 Low-to-Medium Risk • Marine protected areas managed for multiple use or with undetermined protection
• High vessel density areas• Existing submarine cable and pipeline ROW
3 High Risk • Marine protected areas subject to “no take” restrictions
• Hard benthic substrate/rock reef• Commercial benthic fishery• Habitat areas of particular concern
4 Exclusion Areas • Marine protected areas subject to “no impact” or “no access” restrictions
• Areas restricted for military use
