1 ColumbiaGrid Planning Overview Marv Landauer July 13,

2 Overview The three levels of transmission planning Overview of ColumbiaGrid and its activities in the area of renewable generation integration Interconnection-wide planning to integrate renewables

3 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 utilities in a region as if they were all one utility Interconnection-wide Planning Addresses seams between SPGs by planning the entire Western Interconnection as if it were one utility 3

4 Subregional Regional (8 Organizations) (1 Organization) Local Utility (60+ Organizations) Three Levels of Planning 4

5 ColumbiaGrid Nonprofit membership corporation formed in 2006 Independent Board Formed to improve reliability and the efficient use of the grid Coordinates the use and expansion of the grid through open and transparent processes. 5

6 Members/Participants Avista Bonneville Power Administration Chelan County PUD Cowlitz County PUD Grant County PUD Douglas County PUD Puget Sound Energy Seattle City Light Snohomish County PUD Tacoma Power Tonbridge Power Standing invitation to others 6

7 ColumbiaGrid Transmission Planning Independent staff Open stakeholder process Develops Biennial Transmission Expansion Plan Annual System Assessment Conducts studies focused on specific issues Cost allocation

8 Study Teams Puget Sound Area Study Team Northern Mid-Columbia Study Team Cross Cascades Study Team Centralia Closure Study Team Wind Integration Study Team Dynamic Transfer Capability Task Force 8

9 ColumbiaGrid 10-year Plan

10 Regional Transmission Expansion Planning Project Western Electricity Coordinating Council Status: 10-year plan in late year plan in 2013 Will not endorse specific projects Funded by DOE Analyzing different levels of renewable generation development Primary driver for new transmission is the amount of renewable generation that California will import

11 RTEP Benefits Increased coordination among entities in the Western Interconnection Increased awareness of how energy policy decisions impact reliability and cost Ability to answer key policy questions at State, Provincial and Federal levels Additional information for use by decision makers in siting and cost allocation proceedings

12 RTEP Participation TEPPC is governing Committee in WECC Subregional Planning Groups Utilities State and Provincial Steering Group Other Stakeholders

13 Western Renewable Energy Zone Hub Map

14 Subregional Planning Group Coordination Group (SCG) Status: 1. Updating the Foundational Transmission Project List 2. Assisting WECC with reliability analysis of 10year plan 3. Developing more formal procedures for coordinating between SPGs 14
