ColumbiaGrid Planning Overview
Marv LandauerJuly 13, 2010
Overview
• The three levels of transmission planning
• Overview of ColumbiaGrid and its activities inthe area of renewable generation integration
• Interconnection-wide planning to integraterenewables
Three Levels of Planning
• Individual Utility
– The bulk of the projects are developed at this level
• Subregional Planning Group (SPG) Level
– Plans transmission additions for a group of utilitiesin a region as if they were all one utility
• Interconnection-wide Planning
– Addresses seams between SPGs by planning theentire Western Interconnection as if it were oneutility

ColumbiaGrid
• Nonprofit membership corporation formed in 2006
• Independent Board
• Formed to improve reliability and the efficient use ofthe grid
• Coordinates the use and expansion of the gridthrough open and transparent processes.

CoordinatingCouncil
Status:1. 10-year plan in late 20112. 20-year plan in 20133. Will not endorse specific projects4. Funded by DOE5. Analyzing different levels of
renewable generation development6. Primary driver for new
transmission is the amount ofrenewable generation thatCalifornia will import
RTEP Benefits
• Increased coordination among entities in theWestern Interconnection
• Increased awareness of how energy policydecisions impact reliability and cost
• Ability to answer key policy questions at State,Provincial and Federal levels
• Additional information for use by decisionmakers in siting and cost allocationproceedings
RTEP Participation
• TEPPC is governing Committee in WECC
• Subregional Planning Groups
• Utilities
• State and Provincial Steering Group
• Other Stakeholders

Status:1. Updating the Foundational
Transmission Project List2. Assisting WECC with
reliability analysis of 10-year plan
3. Developing more formalprocedures for coordinatingbetween SPGs
