1.0 PURPOSE
The purpose of this study is to create switching procedures for N-2 type situations. An N-2
situation is when any two substations have failed. This study will determine which N-2 situations
can and cannot successfully be handled by the current system. This will indicate weaknesses in
the grid and provide meaningful information for future improvements to the grid. Data from the
study will be divided into three main categories: (1) scenarios that work, (2) scenarios that work
with assumptions, and (3) scenarios that do not work.
2.0 DATA SOURCES
Data needed for creating switching procedures was taken from Idaho Falls Power’s AutoCAD
drawing, IFP-E102 Rev 4, 12.5KV ONE LINE DIAGRAM.
3.0 GUIDELINES AND ASSUMPTIONS
Guidelines and assumptions for the switching procedures were taken from section 4.l of the Load
Forecast Study completed by Ben Jenkins, which states:
Circuit loads ideally to be less than 8.5MW but shall not be greater than 13MW.
Substation loads ideally to be less than 15MW but shall not be greater than 25MW.
For many of the switching procedures it is assumed that the aux bus can be used even when the
rest of the substation is down.
4.0 SUMMARY
Using the current grid, 49 of the 55 possible N-2 type situations may successfully be handled
without interruption to power service. However, 31 of the 45 successful situations currently have
an assumption that the aux bus can be used in the switching procedure. New connections to
Templeview, City, and N. Boulevard’s islanded feeders are needed to remove this dependency.
New connections, switches, and upgraded wire ampacity are also needed at critical points in the
grid to increase grid stability and provide switching procedures for the remaining N-2 situations
that currently cannot be handled.

5.0 BODY/DATA
The following image is a graphical representation of the switching procedures. Each cell in the
table represents one switching procedure. The value in the cell is the combined load, in
Megawatts, that needs to be transferred away from the shutdown substations. The color fill of the
cell indicates how much power is being transferred away from the substations in the procedure in
comparison to other N-2 situations; greener indicates a smaller transfer and redder indicates a
larger transfer. The color of the text represents whether the switching procedure can be
completed (black text), completed with assumptions (light blue text), or if it cannot be completed
(red text). The additional information at the bottom left highlights which substation combinations
cannot be completed.
