Sponsored Projects and Unsponsored Projects identified by the Planning Committee will be evaluated through the use of
Change Cases.
Per customer request, the TransWest Express (Merchant) project will not be evaluated this planning cycle as an Alternative
Project for selection in the Regional Transmission Plan.

Technical Analysis
8
Draft Regional Transmission
Plan Evaluation
• Goal is to identify the most efficient or cost effective
Regional Transmission Plan
• Analysis
– Stressed hours selection (production cost model)
– Reliability analysis (power flow model)
– Metric analysis for benefit determination
• Analysis performed on
– Initial Regional Transmission Plan
• “Roll up” of the Transmission Providers transmission plans
– Change Cases without non-Committed projects
– Change Cases with addition of Alternative Projects and
without non-Committed project
9
Draft Regional Plan Analysis
• No significant reliability problems were identified
– N-0 (steady-state), N-1 (single-contingency), N-2 (credible
double-contingency)
• Voltage/thermal issues evaluated and resolved
• Change Cases evaluated non-Committed projects
– Boardman to Hemmingway (B2H), Energy Gateway (EG), SWIP
North
• One unsponsored non-Committed project was defined
as a result of the quarter 3-4 analysis
10
Metric Analysis
11
Metric: Change in Energy
Losses
•
•
This metric captures a transmission plans’ change in
energy losses
NTTG incremental energy loss computed for the 5
cases studied
–
–
Computed: loss without the non-Committed project less the
loss with the non-Committed transmission project
Benefit = reduction in losses
•
Average the 5 case results, annualize the data and
multiply by nodal energy price
•
•
Result = monetized annual benefit
Power flow analysis
12
Metric: Change in Reserve
• Identifies potential benefit of new transmission to lower
the reserve capacity costs of two or more entities
assuming:
– Incremental load and generation
additions for the 10 year planning
period
– Generation capacity based on a
simple cycle Frame F ($800/kW)
– Reserve event energy costs based
on the TEPPC 2024 case zonal
gas prices
• Four transmission
upgrades examined

Metric: Capital Cost
• TEPPC Transmission Capital Cost tool
– Validate project capital cost if submitted by project sponsor
– Develop capital cost estimate if not submitted
• TEPPC annual capital related cost model
– Develop the annual capital-related costs over 40 years
• Developed incremental costs as the sum of:
–
–
–
–
Levelized annual capital-related costs
Monetized annual energy losses
Monetized annual reserves
Effects on neighboring regions (mitigated internal to NTTG)

** Alternate Project required an unsponsored non-Committed project from Aeolus to Populus to
eliminate reliability problems external to NTTG footprint.
15
Draft Regional Transmission Plan
• Based on the studies performed thus far the Draft
Regional Transmission Plan is:
― Initial Regional Transmission Plan without the non-Committed
projects, and
― Addition of a unsponsored non-Committed project from Aeolus
(southern Wyoming) to Populus (Idaho)
• Lesson Learned
― The Study Plan did not fully account for transmission service
obligations received during the Q1 data submittal period
• Revise the Study Plan in Q5 to address this concern
16
Possible Revision to the Biennial
Study Plan
• Include two threshold requirements
– Plan must be a reliable transmission system
– Plan must meet the transmission needs:
•
•
•
•
•
Loads
Resources
Public Policy Requirements
Transmission service obligation and
Other identified transmission requirements
• Implement the revised Study Plan in Q6 analysis
• Develop the Draft Final Regional Transmission Plan in
