9 Appendix E Iron Range With Fargo Tap Sensitivity E.1 Summary The scenario of a tap on the Winnipeg-Iron Range line going to Fargo was added to the eastern configuration and studied. E.1.1 Fargo Injection The most limiting first contingency incremental transfer for the Fargo wind injection is shown in Table E.1-1. Table E.1-1 Worst Case Limiters Fargo Wind Injection Outage Case West -240 Bison-Maple River 230 kv line Bison-Maple River 345 kv line \NISI East 670 Bison-Maple River 230 kv line Bison-Maple River 345 kv line Maple River 345/230 kv tx 2 Maple River 345/230 kv tx 1 Y181 East with Fargo Tap -340 Stone Lake 345/161 kv Tx Stone Lake-Gardner Park 345 kv line T1B1 Eastern Line with Fargo Tap The Eastern with Fargo Tap provides a path that balances the lines from Manitoba better than without the Fargo Tap. The tap line provides a path parallel to the CapX Fargo-Twin Cities to get wind injection out of the Red River Valley. Higher levels of wind injection can be reached before additional transmission lines are required. Being the power has a more direct connection to the Arrowhead area, the Roseau capacitors and Stone Lake transformers need upgrading, which is not required without the Fargo Tap line. E.1.2 Fargo/Brookings County Injection The most limiting first contingency incremental transfer for the Fargo/Brookings wind injection is shown in Table E.1-2. Table E.1-2 Worst Case Limiters Fargo/Brookings Wind Injection Outage Case West -530 Bison-Maple River 230 kv fine Bison-Maple River 345 kv line W162 East 1130 Split Rock-White 345 kv line Brookings Co-Lyon Co 345 kv line Y1B2 East with Fargo Tap 1125 Split Rock-White 345 kv line Brookings Co-Lyon Co 345 kv line T1B2 Eastern Line with Fargo Tap

10 The Eastern Line with Fargo Tap provides for more wind injection with less transmission improvements then the western line but slightly less than the eastern line without the tap. The benefit of the eastern line with the Fargo tap is it ties the Red River Valley into the eastern side of Minnesota for wind injection while providing Manitoba power to the Red River Valley when needed. E.2 Study s For the purpose of this study, there were three main transmission options: the west (Bison) or east (Blackberry) lines coming out of Dorsey and the east (Blackberry) line with a 345 kv line from Fargo tapping the Dorsey to Blackberry line. The cases studied are listed in Table E.2-1 Study s. With the wind injection at the Bison 345 kv bus or at the Bison and Brooking County 345 kv buses.

16 E.3 Results All comparisons were done using incremental costs. When a phase shifter was added to the Harvey- Glenboro 230 kv line, it made minimal differences in the overall results. The phase shifter was too far west of the injected areas to have a major effect on the study area. E3.1 Fargo Wind Injection Results Eastern with Fargo Tap Fargo Wind Injection The eastern option with the Fargo tap scenarios all have a line from Dorsey to the Blackberry with 50 series compensation with the line tapped (T-Tap) south of the series compensation, a double circuit 345 kv line from T-Tap to Bison, a double circuit 345 kv line from the Blackberry to Arrowhead, two 500/345 kv transformers at Blackberry, one 345/230 kv transformer at Blackberry, and one 500/345 kv transformers at T-Tap. Only three scenarios were evaluated for this option, T1A, T1B, and T2B. With these scenarios, the Manitoba power and the wind injection are entering the 345 kv system at totally different points but are tied together. Most of the same upgrades due to Ca px line outage are still required but at higher wind injection. Some occur after the 2000 cutoff. The Roseau capacitors overload for two of the three scenarios and the Stone Lake 345/161 kv transformer overloads for all of the three scenarios. The best performing scenario was the T1A which can go to the 2000 transfer level without the Roseau series capacitors system intact overloads. The Roseau series capacitors system intact overloads occur at higher transfer levels than the Fargo option. The Bison-Maple River 345 kv, Bison-Maple River 230 kv, Maple River-Sheyenne 230 kv, Fargo- Moorhead 230 kv, Maple River-Frontier 230 kv, and Sheyenne-Audubon 230 kv lines and the Maple River 345/230 kv transformers overload for the loss of Bison-Alexandria 345 kv line are over 1000 wind injections when there is not an additional outlet for the wind injection out of the Fargo area. These lines still overload for some other scenarios but at higher wind injection levels. When the loss is the Alexandria-Quarry 345 kv, line the 115 kv system in the Alexandria area in addition to the Fargo area 230 kv system overloads. For T1A scenario, it occurs before the Fargo area overloads, For a loss of the Quarry-Monticello 345 kv line, the 115 kv system in the St. Cloud area, Alexandria, and Fargo 230 and 115 kv system overloads. The overload output for all scenarios ran is in Appendix E. The scenario with the lowest incremental cost is T2B but it only allows a transfer of The second lowest incremental cost is T1A which is the Fargo Tap option and it is able to transfer A chart showing the incremental cost is in Figure E The scenario with the highest incremental cost is T1B.

18 Comparison of s Fargo Wind Injection The least incremental cost scenario is Y2A, eastern option with line Bison-Brookings County. The line only goes from Bison to Brookings County with transformers required at both ends. It provides to two independent outlets from Fargo for the wind injection. The east option with only 345 kv line instead is ranked fourth. The eastern option with the tap overloads the east transmission more. The second least cost incremental is Y2B which includes Stone Lake and Chisago Country #1 and #2 transformers upgrades. T2B is not the least cost option, but it provides for three independent outlets for wind injection from Bison and provides for a tie to North Dakota for the Manitoba generation, but it only has a 1820 transfer capability. A table showing the incremental cost is in Table E The most costly incremental is Y1A, there are no additional independent outlets for the wind injections and upgrades to the 115 and 230 kv system are extensive. The Fargo options are not capable of getting the 2000 transfer. The chart comparing the wind injection options is shown in Figure E In order to compare easier the following charts have the data separated into individual options with both the Fargo wind injection and the Fargo/Brookings wind injection Figure E to Figure E The eastern option has the first limiters occurring at higher wind injection than the other two options. For the eastern option with the Fargo Tap Stone Lake 345/161 kv transformer is a negative number for the Fargo wind injection. For the western option the first limiter is the Roseau capacitor banks. See Table E3.1-6 for the complete list of first limiters. The eastern options have fewer system intact overloads than the western options. Also they occur at higher wind injection levels. The eastern options with the Fargo tap have even few system intact overloads than without the tap. A table showing the system intact overloads is in Table E3.1-7.

39 E3.2 Fargo and Brookings Wind Injection Results The Fargo/Brookings wind injection did not have as many cases that were ran as for the Fargo only wind injection. The wind injection is split 50/50 between Fargo and Brookings Co sites. The same amount of maximum power of 2000 was used. Eastern with Fargo Tap Fargo/Brookings Wind Injection The eastern Fargo tap scenarios all have a line from Dorsey to the Blackberry with 50 series compensation with the line tapped (T-Tap) south of the series compensation, a double circuit 345 kv line from T-Tap to Bison, a double circuit 345 kv line from the Blackberry to Arrowhead, two 500/345 kv transformers at Blackberry, one 345/230 kv transformer at Blackberry, and one 500/345 kv transformers at T-Tap. Only three scenarios were run for this option: T1A, T1B, and T2B. With these scenarios the Manitoba power and the Fargo wind injection are entering the 345 kv system at totally different points but are tied together. Being one half the wind injection is at Brookings Co, only the Bison-Maple River 230 kv line upgrade due to CapX line outages still required. The Chisago 500/345 kv transformer #1 and #2 upgrades are required for loss of the other transformer except for TIA which has the double circuit CapX Fargo-Twin Cities. The Roseau capacitors or the Stone Lake 345/151 kv transformer do not overload with only half the wind being injected at Fargo. The best performing scenario was the T1A; it provides for an independent outlet from Bison but does not tie the Bison and Brookings Co. wind injection areas together directly. The scenario with the lowest incremental cost is T1A (Fargo Tap option with CapX Fargo-Twin Cites 345 kv double circuit line). The other two scenarios are the same cost. A chart showing the incremental cost is in Figure E The scenario with the highest incremental cost is T1A.

41 Comparison of s Fargo/Brookings Wind Injection The least incremental cost scenario is Y2A, eastern option with line Bison-Brookings County. The line only goes from Bison to Brookings County with transformers required at both ends. It provides to two independent outlets from Fargo for the wind injection. The eastern option with a 345 kv line is a very close second. The eastern option with the tap T1A ties the Manitoba power and both wind injection sites together, overloading the Split Rock-White 345 kv line requiring an upgrade. T1A also includes Stone Lake and Chisago Country #1 and #2 transformers upgrades. A chart showing the incremental cost is in Figure E A table with the incremental costs is shown in Table E The most costly incremental is W1A, there are no additional independent outlets for the wind injections and upgrades to the 230 kv system in the Red River Valley. The eastern option has the first limiters occurring at higher wind injection than the other two options. For the eastern option with and without the tap the Split Rock-White 345 kv line is usually the first limiter. For the western option the Roseau capacitor bank is the first limiter. See Table E3.1-6 for the complete list of first limiters. The eastern option only had one system intact overload, Y2A, Split Rock-White 345 kv line at The eastern option with the Fargo tap had none. The western option had the Roseau capacitor bank and Split Rock-White 345 kv line for some of the scenarios. A table showing the system intact overloads is in TableE3.1-7
