Scenario Case 3,000 MW scenario from Wyoming to Southern Nevada
Requires remedial actions to mitigate violations for DC line bipole
outage 2,650 MW scenario DC bipole outage produces few violations
and FACRI action can result in no violations 5

Public Policy Requirements and Considerations Public Policy
Requirements are established by local, state, or federal laws or
regulations and regulations promulgated by a relevant jurisdiction
Public Policy Considerations are not established by local, state,
or federal laws or regulations 13
Slide 14
Selection of Public Policy Considerations to Study The Planning
Committee will determine the Public Policy Considerations to be
included in additional study analysis The additional study analysis
results are informational only and may inform the Regional
Transmission Plan, but will not result in the inclusion of
additional projects in the Regional Transmission Plan 14
Slide 15
Renewable Northwest Project Request Understand the transmission
impacts associated with retiring 1) Colstrip units 1&2 and 2)
Colstrip units 1, 2, 3, & 4 Replacing the respective amounts of
capacity with proportional amounts of wind capacity in Montana

Slide 16
Northwest Energy Coalition Request Assess an accelerated phase
out of coal plants and enhancement of clean energy resources
(energy efficiency, demand response, distributed generation, and
utility-scale renewable resources) Assess how to maximize the
delivery of renewable energy and minimize new transmission TEPPC
