Osage Creek to Grandview: New Line
10CP-EAI-013
Scenario:
•
By 2010, it is estimated that approximately 227 MW of load will be served
between Harrison East and Eureka Springs.
•
Loss of the Harrison East to Harrison South transmission line segment results
in a thermal overload of the Eureka to Osage Creek (AECC) line segment.
•
Loss of this line also results in low voltage at key load centers.
Proposed Solution:
•
Construct a new switching station, Grandview, on the transmission line from
Table Rock Dam to Eureka Springs. Build a new line between Grandview and
Osage Creek.

Scenario:
11CP-EAI-011
•
The loss of the Independence to Newark 161kV line segment causes low
voltages at Newark, Rutherford, and Southside substations.
•
Rutherford has a 36MVAR capacitor bank that can not be switched during the
contingency because of the large voltage rise.
Proposed Solution:
•
By moving the capacitor bank to Pangburn substation, the TOC will be able
to switch the capacitor bank in service when needed, even during a
contingency such as the loss of Independence to Newark line.

Holland Bottom: Construct 500/161/115 kV
Substation
Scenario:
10CP-EAI-015 1-2
•
In previous summers, several stations in Little Rock observed low voltages with no
significant contingencies.
•
The loss of one of the 500/115 kV transformers at Mabelvale in 2006 resulted in low
voltages in the Little Rock area during periods where heavy flows to the north were
occurring.
•
A loss of the second transformer at Mabelvale (N-2) could result in widespread low
voltage in the Little Rock area.
Proposed Solution:
•
Phase 1: Construct a 500/115kV substation near Cabot Northeast of Little Rock. This
will provide voltage support to Little Rock and reduce some thermal contingencies.
•
Phase 2: Install 161 kV Bus and a 600 MVA 500 kV / 161 kV Autotransformer. This will
provide a strong source into Conway from the East. The 161kV at Holland Bottom will
also provide a long term conversion of the 115kV to North Little Rock and to Searcy
Price.

Holland Bottom to Hamlet: New Line
Scenario:
•
10CP-EAI-017
The loss of the 161 kV transmission line from Pleasant Hill to Quitman causes
an overload on the Conway West to Donaghey and Donaghey to Conway
South 161 kV transmission line sections. There are two key 161 kV
transmission lines sensitive to daily and long term/firm transactions in the
area north and northwest of Little Rock. One of the lines runs through the
City of Conway (Morrilton East to Quitman) and the other is north of Conway
(Pleasant Hill to Quitman). In the event the Pleasant Hill to Quitman line is
outaged the Morrilton to Conway West to Quitman 161 kV line remains as the
primary line to accomodate both the load in the Conway area and
transactions flowing North.
Proposed Solution:
•
•
•
•
Convert Hamlet SS to a breaker station (Single Bus Single Breaker Scheme)
Move the Quitman line from Gold Creek to Hamlet SS
Move the Gravel Ridge line from Gold Creek to Hamlet SS

Ebony: Install a 6 Breaker Ring Bus
Scenario:
10CP-EAI-018, 11CP-EAI-006
•
The loss of West Memphis EHV to West Memphis Polk causes low voltages at
WM Polk and WM Lehi. To prevent this, Ebony SS will be converted to a
breaker station.
•
Ebony SS ties together Kuhn Road, WM Gateway, Marked Tree, WM Lehi and
WM Polk. The current configuration has Marked Tree to WM Lehi bypassing
the switching station. This also prevents a creation of an operational guide
for the TOC to remove the low voltages condition if an event should occur.
Proposed Solution:
•
Convert Ebony SS to a 5 breaker station. Additional land may need to be
purchased.
•
Install 21.6 MVAR Capacitor Bank.

Woodward: Reconfigure 115kV Bus
Scenario:
•
12CP-EAI-003
The 115kV bus is a single bus single breaker scheme with a bus tie
separating the North and South buses. By reconfiguring the Woodward
115kV bus into a folded breaker and a half scheme, a full 115kV bus outage
will not occur for a single stuck breaker or breaker fault. This will eliminate
the potential of voltage collapse in the Pine Bluff area for an outage on the
North and South 115kV buses.
Proposed Solution:
•
The North and South Woodward 115kV buses will be converted to a folded
breaker and a half scheme. Once the project team has had a chance to
evaluate the Woodward 115kV bus and determine the best approach, the
project team and planning can work together to evaluate which 2 lines will
share a common breaker in the breaker and a half scheme.

Camden MaGuire to Camden North: New 115kV Line
Scenario:
•
12CP-EAI-005
Loss of the breaker-to-breaker segment from Camden North to McClellan leaves the
very long line single-ended from Woodward. Loss of the breaker-to-breaker segment
from McClellan to Camden Maguire also leaves the very long line single-ended, and if
the McClellan plant is not generating, there is insufficient voltage support for the area.
Proposed Solution:
•
Using 1200 amp breakers, switches, and other substation equipment, rebuild the
existing Camden North substation to accommodate three transmission lines. Two of
the three transmission lines will be the existing two lines at the substations (line to
McClellan and line to Fordyce). The third line will be a new 115 kV transmission line
