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. Proposed In Service Date: Summer 2011 (Current Projected ISD Winter 2011) 9 Energy Delivery Osage Creek to Grandview: New Line 10CP-EAI-013 Grandview 161 kV Substation Grandview to Osage Creek 161 kV Line: Construct New Line Proposed In Service Date: Summer 2011 (Current Projected ISD Winter 2011) 10 Energy Delivery Pangburn: Relocate Rutherford Capacitor Bank to Pangburn 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. Proposed In Service Date: Summer 2011 11 Energy Delivery Pangburn: Relocate Rutherford Capacitor Bank to Pangburn 11CP-EAI-011 Pangburn: Install Cap Bank Proposed In Service Date: Summer 2011 12 Energy Delivery West Memphis to Bermingham Steel 500 kV Line: Increase Flowgate Capacity 10CP-EAI-031 Scenario: • Numerous TLR events were initiated during the summer of 2010 and previous summers based on the 1732 MVA rating of the West Memphis Birmingham Steel 500 kV line. Proposed Solution: • Replace 500kV breaker, six line traps, and two switches at West Memphis 500 kV substation. Proposed In Service Date: Fall 2011 13 Energy Delivery West Memphis to Bermingham Steel 500 kV Line: Increase Flowgate Capacity 10CP-EAI-031 West Memphis: Replace 500kV Breaker, Line Traps, and Switches Proposed In Service Date: Fall 2011 14 Energy Delivery 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.

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 Construct a line from Hamlet SS to Holland Bottom with a rating no less than 1200 Amps Proposed In Service Date: Summer 2012 19 Energy Delivery Holland Bottom to Hamlet: New 161kV Line 10CP-EAI-017 Hamlet: Convert to a breaker station Construct a new 161 kV Transmission Line from Holland Bottom to Hamlet Holland Bottom Proposed In Service Date: Summer 2012 20 Energy Delivery 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. Proposed In Service Date: Summer 2012 21 Energy Delivery Ebony: Install a 6 Breaker Ring Bus 10CP-EAI-018, 11CP-EAI-006 Ebony SS: Convert to a 5 Breaker Ring Bus and add capacitor bank Proposed In Service Date: Summer 2012 22 Energy Delivery Hilo: Install New 10.8MVAR Capacitor Bank Scenario: • 11CP-EAI-010 Hilo is a substation located in southeastern Arkansas, northeast of El Dorado.

Also the loss of the Marked Tree to Harrisburg Tap 161 kV Transmission Line segment results in the Jonesboro to Hergett 161 kV Transmission Line segment to overload. Proposed Solution: • Re-conductor the Jonesboro to Hergett 161 kV Transmission line segment to at least 240 MVA. Proposed In Service Date: Summer 2012 25 Energy Delivery Jonesboro to Hergett: Upgrade Line 10CP-EAI-019 Re-Conductor the 161 kV Transmission Line from Jonesboro to Hergett Proposed In Service Date: Summer 2012 26 Energy Delivery Transmission Service (Westar): Upgrade Lines 10CP-EAI-022 1-3 Scenario: • Transmission Service Proposed Solution: • • • Re-conductor the Monette to Paragould 161 kV (Base Funding) Transmission line segment to at least 246 MVA.

Proposed Solution: • • • Abandon existing Benton South switch station. Construct a new 4 breaker station named Woodlawn Road to be located south of Benton South substation. The breakers for the ring at Woodlawn Road substation will be Woodlawn Road to Haskel, Woodlawn Road to Bauxite, Woodlawn Road to Benton South, and Woodlawn Road to Benton North. Construct a new transmission line from Woodlawn Road to Benton North. The new line is about 9 miles and needs to be rated to at least 176 MVA. Abandon Benton North Tap. Construct a new 4 breaker station named River Ridge about 3 miles north of Benton North Substation. The breakers for the ring will be River Ridge to Benton North, River Ridge to Congo AECC, River Ridge to Avilla, and River Ridge to AECC Crows.

There is a capacitor bank at Fordyce and it is installed on the line from Fordyce to Camden North on the Bearden line section. The line section from Fordyce to Bearden can be sectionalized but there are no switches such that the capacitor bank can be re-energized while the line section is out of service. Proposed Solution: • Install a 1200 amp line switch on the Fordyce to Bearden line section South of the capacitor bank at Fordyce.

Proposed In Service Date: Summer 2015 45 Energy Delivery Woodward to Pine Bluff West to McCamant: Upgrade Lines 12CP-EAI-002 Woodward to Pine Bluff West To McCamant: Upgrade Lines Proposed In Service Date: Summer 2015 46 Energy Delivery 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.

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 constructed from Camden North to Camden Maguire.
