4 Executive Summary (BHC) conducted a System Impact Study (SIS) in response to the request to provide interconnection service for the proposed generation facility under the guidance of the Black Hills Colorado Transmission (BHCT) Open Access Transmission Tariff Large Generator Interconnection Procedures (LGIP). This section summarizes the SIS results for the BHCT-G11 interconnection request. Disclaimer The results of this SIS are highly dependent on the assumed system topology and the timing of projects in the vicinity of the proposed interconnection, which are subject to change. Interconnection Service in and of itself does not convey any right to receive transmission service to any specific customer or Point of Delivery. It should be noted that carrying out the system upgrades identified in this report does not guarantee transmission service for the customer. Transmission Service should be requested through the BHCT OASIS and the request will be granted on a first-come, first serve basis. Background A valid interconnection request for the 29 MW project was received from the interconnection customer (IC) on May 2, The IC elected to forgo the Feasibility Study and proceed with the SIS phase of the LGIP. The proposed project consists of sixteen (16) Vestas V100 wind turbine generators (WTG), and will connect to the Black Hills Colorado Electric (BHCE) 11 kv transmission system at the Rattlesnake Butte substation located at the wind project site in Huerfano County, Colorado. The BHCT- G11 interconnection request represents Phase III of a wind project; (BHCT-G8) was recently put into service for the same IC. The point of interconnection for the BHCT-G8, G10, and G11 interconnection requests will be the 11 kv Rattlesnake Butte substation. The IC requested that the project be evaluated as a Network Resource (NR) as well as an Energy Resource (ER) on the BHCT system. The requested commercial operation date of the project is December 31, Analyses consisted of computer-based power flow analysis, transient stability analysis, and short circuit/fault duty analysis. This study modeled the proposed generation interconnection under 2017 Summer Peak and Light Autumn conditions, and the transient stability analysis also included a 2017 Summer Peak and Light Autumn scenarios. Select contingencies which stressed the transmission system were simulated. Power flow and transient stability results were monitored for BHCT and other neighboring systems. Short circuit impacts were monitored for the buses in the immediate project area. The criteria applied in this study are consistent with NERC/WECC Reliability Criteria. For more detailed information on the criteria used for each analysis, refer to Section 2.2. Results No detrimental impacts to the BHCE and surrounding transmission system were identified as a result of the interconnection of the BHCT-G11 wind generation project. 4

5 Conclusions The 29-MW injection from BHCT-G11 (ER or NR) could be accommodated at the POI with the following required network upgrades: New 11 kv terminal position at the BHCE 11 kv Rattlesnake Butte substation Proceed with transmission system upgrades previously identified in the 2012 TCPC study report to increase the rating on the Desert Cove-West Station 11kV line and Portland-Skala 11 kv line (G11 as an ER only). The new 11 kv circuit breaker required for this new terminal will convert the bus configuration from a three breaker ring bus to a four breaker ring bus. In addition to the network upgrades mentioned above, a MVAR shunt reactor at the POI substation will be required of the Interconnection Customer. This requirement is independent and in addition to that required for BHCT-G11 as shown in Figure 3. The estimated cost of the system upgrades is $1,499,602. The estimated completion time for the system upgrades is approximately 12 months (engineering design/materials procurement/construction & commissioning).

6 1. Introduction Black Hills Colorado Electric owns certain transmission facilities with transmission service pursuant to a FERC-approved Open Access Transmission Tariff ( OATT ). A valid request was received from the Interconnection Customer (IC) on May 2, 2012 to provide interconnection service for the proposed generation facility under the guidance of the Black Hills Colorado Transmission OATT Large Generator Interconnection Procedures. The IC elected to forgo the Feasibility Study and proceed with the SIS phase of the LGIP. The proposed project consists of sixteen (16) Vestas V100 wind turbine generators nominally rated at 1.8 MW each, and will connect to the BHCT 11 kv system at the Rattlesnake Butte substation in Huerfano County, Colorado. The IC requested that the project be evaluated as a Network Resource (NR) and an Energy Resource (ER) on the BHCT system. The requested commercial operation date of the project is December 31, Study Scope The study considered the impacts of the interconnection request by analyzing the transmission system before and after the interconnection of the proposed project. The study included steady state and transient stability analysis for both the 2017 peak summer and offpeak autumn load scenarios. The study also included short circuit analysis and provided a cost estimate and implementation schedule for suggested system upgrades, if applicable, to accommodate the proposed project Study Area The study area included all BHCE transmission equipment as well as neighboring transmission system elements roughly bound by Poncha to the west, Walsenburg to the south, Lamar to the east, and Daniels Park to the north. A diagram of the study area is shown in Figure 1. Points of interconnection between BHCE and neighboring utilities are shown in Table 1.

8 1.3. Benchmark Cases The 2017 heavy summer and light autumn study scenarios were utilized from the 2012 near term TCPC study cycle. The 2017HS case originated from the Colorado Coordinated Planning Group (CCPG) 2012 Compliance Study case (ccpg_2017hs_r2.sav) which was also created from a WECC 2017HS1A approved base case. Similarly, the 2017LA case came from the 2012 CCPG Compliance Study. This case contained a similar transmission system topology and reduced area loads, as well as a relatively high output from the Busch Ranch wind project. Significant changes to the existing 2012 Black Hills transmission system to create the 2017 model included projects planned for completion this year and all budgeted projects listed in the most recent version of the BHCE Strategic Plan.

N. Clark coal-fired power plant in Cañon City. The W. N. Clark plant suspended operations on Dec. 31, 2012 and will be retired on Dec. 31, The exact location and amount of the replacement generation resources is to be determined. It should be noted that the San Luis Valley-Calumet-Comanche transmission project and the Lamar Front Range transmission project were not included in the 2017 study cases. The current in-service date for both projects is to be determined Project Model The proposed projects, Phase I (BHCT-G8), Phase II (BHCT-G10) and Phase III (BHCT- G11) were represented in the power flow model as three equivalent WTGs rated at 28.8 MW each, operated with +9.36/ MVAR capability. Each generator step-up (GSU) transformer increased the voltage from 0.69 kv to 34. kv, with an equivalent impedance value of 9.00% with a X/R ratio. The high side of each GSU will interconnect to an underground collector system with assumed equivalent impedance of j0.014 per unit, and a susceptance of per unit. The equivalent network impedance based upon WECC Wind Power Plant Power Flow Modeling Guide, May 2008, Table 1 Sample Equivalent Collector System Parameters was modeled in the absence of design data. A single 11:34. kv station transformer rated at 3 MVA was modeled with an impedance value of 7.00% with a 29.2 X/R ratio. This was based upon transformer information supplied by the Consulting Engineers. 8

11 The transient stability models developed by Vestas for the V100 WTGs were supplied by the IC and were used to represent the proposed project. These models are included in Appendix A. 1.. Network Facility Alternatives No alternative transmission options were evaluated. The BHCT-G11 point of interconnection is located at the new facility constructed for BHCT-G8 and the proposed BHCT-G Interconnection Requirements Reactive Power Requirements The proposed project shall maintain a composite power delivery at continuous rated power output at the POI at a power factor within the range of 0.9 leading to 0.9 lagging, across the range of near 0% to 100% of facility MW rating, with the magnitude of reactive power calculated on the basis of nominal POI voltage (1.0 p.u. V). The design shall consider the effects of step-up transformer reactance and voltage taps/turns ratios, and bus-fed auxiliary load. Based on the plant data supplied by the IC and the results of the SIS, the proposed project may need supplemental reactive voltage support equipment to meet these requirements. It is assumed that these requirements are independent and in addition to those required for BHCT-G8 and G10 as shown in Figure 3. If BHC requires additional reactive power support or voltage regulation to mitigate known system weaknesses, BHC will negotiate with the generator owner for any additional capability beyond the minimum requirements stated above. Refer to BHC s Facility Connection Requirements document for details on excitation systems, voltage regulation, governor requirements, etc. 2. Study Methodology This section summarizes the methods used to derive the power flow, low voltage ride through analysis, transient stability, and short circuit results Assumptions The SIS was performed with the following assumptions: All existing and planned facilities and the effects of control devices and protection systems were accurately represented in the system model. Projected firm transfers were represented per load and resource updates. Existing and planned reactive power resources were modeled to ensure adequate system performance. BHCT-G8 and BHCT-G10 are in service and generating at full output (29 MW each). There were no specific planned outages identified for the 2017 study period. The list of the evaluated prior and forced outages used to simulate NERC TPL Reliability Standard Category A, B & C contingencies is included in Appendix B. 11

12 The power flow analysis was performed with pre-contingency solution parameters that allowed adjustment of load tap-changing (LTC) transformers, static VAR devices including switched shunt capacitors and reactors, and DC taps. Post-contingency solution parameters allowed adjustment of DC taps and adjustment of switched shunt elements outside the study area. Area interchange control was disabled and generator VAR limits were applied automatically for all solutions. The solution method implemented for all cases was a fixedslope decoupled Newton solution Reliability Criteria The criteria described in this section are consistent with the NERC TPL Reliability Standards, the WECC System Performance Regional Business Practice (TPL-001-WECC-RBP-2) and Colorado Coordinated Planning Group s Voltage Coordination Guide Steady State Voltage Criteria Under system intact conditions, steady state bus voltages must remain between 0.9 and 1.0 per unit. Following a Category B or C contingency, bus voltages must remain between 0.90 and 1.10 per unit. Pre-existing voltage violations outside the localized study area were ignored during the evaluation Steady State Thermal Criteria All line and transformer loading must be less than 100% of their established continuous rating for system normal conditions (NERC/WECC Category A). All line and transformer loadings must be less than 100% of their established continuous or emergency rating under outage conditions (NERC/WECC Category B and C) Transient Voltage and Frequency Criteria NERC Standards require that the system remain stable and within applicable thermal ratings and voltage limits for Category A, B, and C disturbances. The WECC Disturbance Performance Table of Allowable Effects on Other Systems states the following requirements: Category B: Any transient voltage dip must not exceed 2% at load buses or 30% at non-load buses. The dip also must not exceed 20% for more than 20 cycles at load buses. Frequency must not drop below 9.6 Hz for 6 or more cycles at a load bus. Category C: Any transient voltage dip must not exceed 30% at load buses or 30% at non-load buses. The dip also must not exceed 20% for more than 40 cycles at load buses. Frequency must not drop below 9.0 Hz for 6 or more cycles at a load bus Power Flow Analysis All power flow analysis was conducted with version of PTI s PSS/e software. Power flow results were monitored and reported for transmission system elements in the study area described in Section 1.2. Power flow analysis was used to evaluate the thermal and voltage performance of the system under Category A, B, and C disturbance conditions. Refer to Appendix B for a complete list of simulated prior and forced outages. Thermal loading was reported when a modeled transmission element was loaded over 98% of its appropriate MVA rating modeled in the power flow database and when the incremental 12

13 increase in loading from Pre-Project to Post-Project exceeded 2%. Transmission voltage violations were reported when the criteria described in Section were not met. The proposed project was evaluated as a 29 MW NR, dispatched against existing network resource generation to identify the maximum allowable resource injection the existing transmission system could reliably accommodate. The project was also evaluated as a 29 MW ER, dispatched against the Pawnee Generating Station in northern Colorado. Also the Lamar DC tie was dispatched at 100MW E-W. Table 2 lists the generation dispatch used for each of the aforementioned resource designations for the heavy summer and light autumn demand scenarios, respectively. Table 2: Generation Dispatch Scenarios 2.4. Transient Stability Analysis The objective of the transient stability analysis is to determine the ability of generators to remain in synchronism with one another by surviving the first swing of a disturbance such as a ground fault and subsequent breaker action on the transmission system. Transient stability also simulates the ability of the system as a whole to return to a given steady-state equilibrium after being moved away from it by a small perturbation. Transient analysis was performed to evaluate the dynamic characteristics of the transmission system in proximity to the BHCE footprint following various disturbances. System loads were modeled using the WECC generic motor load penetration of 20 percent, with the under voltage load shedding function disabled to provide a worst-case representation of system performance. The transient stability contingencies were simulated out to 10 seconds to ensure a damped system response. The disturbances evaluated in the transient analysis were selected based on significance with respect to proximity to local generation. The 3-phase faults listed in Table 4 were simulated for the 2017 peak and off-peak scenarios. 13

15 Table 4: Simulated Transient Stability Outages The following parameters were monitored in the 2017HS and 2017 LA scenarios to evaluate system stability performance. Rotor angle plots provide a measure for determining how the proposed generation unit would swing with respect to other generating units in the area. This information is used to determine if a machine would remain in synchronism or go out-of-step from the rest of the system following a disturbance. Bus voltage plots, in conjunction with the relative rotor angle plots, provide a means of detecting out-of-step conditions. The bus voltage plots are useful in assessing the magnitude and duration of post-disturbance voltage dips and peak-to-peak voltage oscillations. Bus voltage plots also give an indication of system damping and the level to which voltages are expected to recover in the steady state conditions. Bus frequency plots provide information on magnitude and duration of post-fault frequency swings with the new project in service. These plots indicate the extent of possible over-frequency or under-frequency excursions, which can occur due to an area s imbalance between load and generation. Other parameters plotted for the 2017HS scenario included generator field and terminal voltage, generator rotor speed, and real and reactive power output. 2.. Low Voltage Ride Through Analysis The current WECC Low Voltage Ride Through (LVRT) Standard requires generators to remain in-service for 3-phase faults with normal clearing (4-9 cycles) and single line-toground faults with delayed clearing that result in a GSU high side voltage of 0.1 per unit or greater. The FERC LVRT requirement specified in Order 661-A, however, requires generation to remain on-line for GSU high side voltages of 0 per unit for similar faults. The more stringent FERC standard was applied as the LVRT requirement for this study. 1

16 The LVRT analysis utilized both 2017HS and 2017LA scenarios with the BHCT-G11 project at 100% of rated output. A 9-cycle 3-phase fault was applied at the 11 kv POI to verify if the proposed project would meet the LVRT requirements Short Circuit Analysis The objective of the short circuit analysis is to determine the impact, if any, that the proposed generation will have on system fault current. The existing fault current levels were identified and compared to post-project fault current levels to determine if existing fault interrupting devices exceeded their rating under simulated fault conditions as a result of the additional generation. It was assumed that all future fault interrupting devices would be designed to accommodate the fault levels identified in this analysis. The software used in this fault analysis was the ASPEN short circuit program. 3. Results The objective of this study was to assess the reliability impacts of the proposed project on the transmission system. This study was not intended to examine pre-existing problems unrelated to the proposed plant, but rather to determine whether the transmission system meets BHCE s performance criteria when the plant is in-service. Under that assumption, a number of preexisting criteria violations were identified during the analysis that were not included in the results section of the report. The following issues were omitted from the report: Operational issues on the 69 kv system related to load service Pre-existing issues identified in the benchmark pre-project case 3.1. Power Flow Analysis The power flow study impacts of the BHCT-G11 project modeled as a NR were negligible with the ER having the most impact. All results mentioned in this section will refer to the project modeled as an Energy Resource Heavy Summer Results There were some adverse impacts to the BHCE and surrounding transmission system identified in the 2017HS power flow analysis as a result of the interconnection of the BHCT- G11 project. The increased overloads with the most impact were on the Desert Cove West Station 11kV line and Portland - Skala 11kV line. The 2017HS power flow results are summarized in Table below. 16

17 Table : 2017HS ER Power Flow Results Light Autumn Results No adverse impacts to the BHCE and surrounding transmission system were identified in the 2017LA power flow analysis as a result of the interconnection of the BHCT-G11 project Transient Stability Analysis The difference in the transient stability study results between the BHCT-G11 project modeled as an ER and a NR were negligible. There were no post-contingent voltage violations or additional frequency criteria violations, and all system oscillations were adequately damped. Due to the large size of plot files created in this analysis, plots were not included in the study report, but are available on request Heavy Summer Results No adverse impacts to the BHCE and surrounding transmission system were identified in the 2017HS transient analysis as a result of the BHCT-G11 interconnection. The system response to all disturbances was adequately damped and exhibited no voltage or frequency violations Light Autumn Results No adverse impacts to the BHCE and surrounding transmission system were identified in the 2017LA transient analysis as a result of the BHCT-G11 interconnection. The system response to all disturbances was adequately damped and exhibited no voltage or frequency violations Low Voltage Ride Through Results There were no indications of generator separation or tripping as a result of the 9-cycle fault at the POI. The BHCT-G11 project met all applicable LVRT requirements Short Circuit Analysis The short circuit analysis was initially performed without the proposed interconnection project. This gave the base case fault duties of the interrupting devices. Then the proposed project was put in service and the short circuit study was repeated. The incremental fault duty difference between the two studies gave the impact of the new generator on the existing 17

18 interrupting devices in the study area. The short circuit fault currents for simulated faults at all of the moderately impacted substations are shown in Table 6. It should be noted that the values in Table 7 represent the largest bus current for the listed fault. Bus faults extending further from the proposed POI than the buses listed in Table 7 were not included in the final analysis due to little or no fault current contribution from the proposed generation project. Detailed fault analysis results are available upon request. 18

19 Table 6: Short Circuit Fault Current Summary Table 6 contains a comparison of the maximum fault current experienced at the faulted bus for any of the simulated faults, as well as the rating of the interrupt devices at that bus. 19

20 Table 7: Short Circuit Analysis Result Summary 20

21 The results of the short circuit analysis show that the maximum fault current with the proposed generation remained considerably less than the minimum interruption rating of any affected existing fault interrupt devices. 3.. Reactive Power Analysis Similar to the BHCT-G8 and G10 projects, the BHCT-G11 project produced a 4 MVAR injection at the POI substation when the WTGs were offline due to the charging effects of the collector system. The reactive power injection did not result in system voltages outside the allowable range. However, the resulting power factor measured at the POI was outside the 0.9 lead/lag requirement due to the purely reactive injection of the project at zero real power output. The project is nearly VAR neutral, but shunt reactive support will be required at the interconnection substation to meet the reactive power requirements specified in Section Also, the Reader-Rattlesnake Butte line consumes 14.1MVAR when all three phases of Busch Ranch are on at full output resulting in a line flow at 71% of its 120MVA rating Power Voltage Analysis A system intact Power Voltage (P-V) analysis was conducted to evaluate the voltage impact of power transfers on the Reader-Rattlesnake Butte line. The source of generation was Busch Ranch phases 1-3 and the sink was the BHCE system. It was determined that the knee point of the P-V curve is when an extra 60MW is transferred in addition to the full output of phases 1-3. The limiting factor is the declining voltage at the 11kV Rattlesnake Butte bus and is also shown in Figure 4. 21

22 Figure 4: Reader-Rattlesnake Butte P.V. Curve 3.7. Results Summary Based on the results of the SIS as described in Section 3, the BHCE transmission system can reliably accommodate a 29-MW injection from the BHCT-G11 project. At least MVAR of reactive voltage support will be required of the interconnection customer to offset the effects of collector system charging under low generation output conditions, as well as directassigned terminal and metering equipment at the POI. This requirement is independent and in addition to that required for BHCT-G8 and G10 as shown in Figure 3. It should be noted that the results described in this report do not guarantee transmission service for the customer. Transmission Service should be requested through the BHCT OASIS and the request will be granted on a first-come, first serve basis. 4. Cost and Construction Schedule Estimates The cost estimates represent good faith estimates necessary to interconnect to the system. The non-binding, good faith cost and time estimates are in 2013 dollars Network Upgrades The addition of a new 11 kv terminal position at the BHCE 11 kv Rattlesnake Butte substation to accommodate the integration of BHCT-G11 is estimated to cost $1,499,602 and take approximately 12 months. Estimates are based on 2013 dollars and lead times for materials were considered for the project schedule.. Conclusions The 29-MW injection from BHCT-G11 (ER or NR) could be accommodated at the POI with the following required network upgrades: 22

23 New 11 kv terminal position at the BHCE 11 kv Rattlesnake Butte substation Proceed with transmission system upgrades previously identified in the 2012 TCPC study report to increase the rating on the Desert Cove-West Station 11kV line and Portland-Skala 11 kv line (G11 as an ER only). The new 11 kv circuit breaker required for this new terminal will convert the bus configuration from a three breaker ring bus to a four breaker ring bus. In addition to the network upgrades mentioned above, a MVAR shunt reactor at the POI substation will be required of the Interconnection Customer. This requirement is independent and in addition to that required for BHCT-G8 as shown in Figure 3. The estimated cost of the system upgrades is $1,499,602. The estimated completion time for the system upgrades is approximately 12 months (engineering design/materials procurement/construction & commissioning). 23
