Post-Technical Conference Questions for Comment

    For any of the following questions, please also describe any issues 
presented when an affected system is a non-public utility transmission 
provider.

General Affected Systems Coordination Processes

    1. Please describe any affected system coordination processes and 
guidance available for your market or balancing authority area, 
including, but not limited to, tariff provisions, joint operating 
agreements (JOA), and business practice manuals (BPM).
    2. Please explain the role of the host transmission provider in 
managing the coordination and communication between an interconnection 
customer and an affected system during the course of an interconnection 
request process. If the interconnection customer has primary 
responsibility to coordinate and communicate with the affected system, 
please explain how the host transmission provider ensures that affected 
system matters are addressed before proceeding with an interconnection 
for which affected system impacts have been raised.
    3. With respect to Midcontinent Independent System Operator, Inc. 
(MISO), Southwest Power Pool, Inc. (SPP), and PJM Interconnection, 
L.L.C. (PJM) specifically, once the need for an affected system study 
is determined, please describe how each RTO then coordinates with the 
other RTO to consider the affected system impacts due to an 
interconnection request on the host system. Please include the steps in 
the process and any timelines and other procedural matters, and 
reference any tariff, JOA, BPM, and/or other provisions that describe 
the process for such coordination.
    4. Should there be a pro forma affected system study agreement that 
provides for firm timelines for the affected system to provide the 
relevant studies? If so, what terms and conditions should it contain, 
and what entities should be parties to the affected system study 
agreement (e.g., host transmission provider, host transmission owner, 
affected system, interconnection customer)? What modifications would 
need to be made to such a study agreement to accommodate a non-public 
utility affected system?
    5. Regardless of whether the Commission proceeds with development 
of a pro forma affected systems study agreement, should MISO, SPP, and 
PJM develop a common affected systems study agreement? If so, what 
terms and conditions should this agreement contain, and what entities 
should be parties to the agreement (e.g., host transmission provider, 
host transmission owner, affected system, interconnection customer)? If 
possible, please provide a sample of a commonly used affected systems 
study agreement.
    6. As part of the affected systems study agreement, if affected 
systems were allowed to charge interconnection customers an 
administrative fee for conducting affected system studies, in addition 
to receiving reimbursement for the actual costs of conducting affected 
system studies, would such a fee motivate affected systems that lack 
resources, such as full-time employees, to conduct affected system 
studies in a more timely manner? If so, how should the fee be 
determined and what milestones of the affected system should be tied to 
the fee? Should such an administrative fee be tied to the affected 
system providing its study results by a certain date?
    7. Describe any planned or in-process affected system coordination 
improvement efforts taking place in your market or balancing authority 
area (through a stakeholder process, etc.). Please provide links or 
directions to any publicly available materials related to these 
improvement efforts.

Modeling and Study Procedures Used for Affected Systems Information

    1. Please explain how Network Resource Interconnection Service 
(NRIS) and Energy Resource Interconnection Service (ERIS) are modeled 
both when conducting studies on your system and when conducting studies 
as an affected system, and provide a reference to where that 
information is located in your tariff. Are the standards (e.g. shift 
factors, contingency lists) for modeling NRIS and ERIS available to 
customers, and if so, where is this information located?
    2. Explain the reasons an affected system would study an 
interconnection request made in a host system using NRIS criteria when 
the interconnection customer is only requesting NRIS in the host 
system. What are the benefits and drawbacks to studying and also 
requiring an interconnection customer seeking NRIS in the host system 
to be responsible for network upgrade costs in an affected system in 
the same manner as an interconnection customer who requests NRIS in the 
affected system?
    3. Explain the reasons an affected system could or should study an 
interconnection request using ERIS criteria when the interconnection 
customer is requesting NRIS in the host system. If you believe affected 
system transmission providers should study NRIS requests as ERIS, 
please include an explanation of how ERIS criteria address reliability 
concerns associated with an NRIS interconnection request in both the 
host and affected systems.
    4. Should there be a standard approach to determine if an 
interconnection customer requesting NRIS in the host system is studied 
as NRIS or ERIS on an affected system? If so, what should the standard 
be and why?
    5. If there is no generic reform that dictates how affected systems 
study interconnection customers who request NRIS on the host system, 
should MISO, SPP, and PJM develop a standard approach to determining 
whether such an interconnection customer should be studied as NRIS or 
ERIS on the affected system(s) during the modeling process? If so, what 
should the standard be and why?
    6. Please explain the process used to calculate generation shift 
factors, including how and where the reference bus is selected, when 
conducting an affected system study for interconnection requests made 
in a host system.
    7. What are the dispatch assumptions used in affected systems 
studies? Are the dispatch assumptions the same for already 
interconnected resources on the host system that affect flows on the 
affected system and resources already interconnected in the affected 
system? Are these dispatch assumptions consistent with the assumptions 
an affected system uses when it performs an interconnection request 
within its footprint? Are the dispatch assumptions an affected system 
uses in affected system studies provided to

[[Page 18287]]

interconnection customers? To the extent already interconnected 
resources on the host system are assumed to be dispatched at full 
output, what is the rationale for that assumption?
    8. What criteria do transmission providers use to determine whether 
an interconnection request on the host system requires an affected 
system study on an affected system? Please provide references to 
tariff, JOA, BPM, and any other provisions that include this criteria. 
If the determination is based on ``engineering judgment,'' is this 
judgment adequately explained to the interconnection customer? If so, 
in what form does the interconnection customer receive that 
information? If there is a disagreement regarding this determination, 
is there a process for the customer to challenge it? If so, please 
provide a detailed description of that process.
    9. Should MISO, SPP, and PJM be required to use the same criteria 
to determine whether an interconnection request on the host system 
requires an affected system study on an affected system?
    10. Please comment on the possibility of implementing jointly 
developed interconnection-wide transmission models between transmission 
providers in affected system studies to detect topology changes to a 
transmission provider's region that might not be visible by the 
affected systems until the next interconnection-wide model update.
    11. When an affected system studies an interconnection request, 
should it model its entire footprint or a sub-region(s) of its system? 
If a sub-region(s) would be sufficient, please explain what criteria 
would be used to determine the sub-region(s) in an affected system that 
are impacted by an interconnection request in a host system.
    12. What are the benefits and drawbacks for the interconnection 
customer, the host transmission provider and the affected system to an 
affected system studying all interconnection requests in a host system 
study cluster or queue to determine affected system impacts? Is there a 
way the host system could employ some type of pre-screening process to 
limit affected systems analysis to only those requests that may impact 
an affected system? What criteria should be used in such a pre-
screening process?
    13. At what point in the interconnection process should 
interconnection customers be required to provide relevant modeling data 
to best avoid delays in both the host interconnection and affected 
system study processes?

Timing of Affected System Coordination

    1. Does the host system's interconnection process include an 
opportunity for the host system and interconnection customer to review 
an affected system study and discuss the results with the host system 
or affected system, as necessary, before the interconnection process 
either requires a financial milestone payment or execution of an 
interconnection agreement? If so, please provide references to the 
relevant tariff or manual descriptions of this opportunity. Is this 
opportunity to review included in the host system's interconnection 
queue timeline? If so, how much time is allowed?
    2. Should all host system transmission providers be required to 
align their interconnection study process schedules with any relevant 
affected systems in order to allow for both host system and affected 
system studies to occur on the same timeline? Would such alignment 
improve the timing at which an interconnection customer receives 
affected system study results? What actions could the host system, 
affected system, and interconnection customer take to better align the 
completion of affected system study results? Should the Commission 
require that an interconnection customer receive affected system study 
results at the same time it receives a host system's system impact 
study results? If so, would there be any concerns with that approach?
    3. Should MISO, SPP, and PJM be required to adopt a common timeline 
for conducting affected systems studies and providing results to 
interconnection customers and/or the host transmission provider? If 
not, why not? If so, please explain how this common timeline could be 
implemented. For example, would each RTO begin affected system studies 
at certain set dates throughout the year and commit to providing 
results by certain set dates, or are there other ways of implementing a 
common timeline? Please also provide an example of how this common 
timeline could be developed--that is, by providing sample tariff, JOA, 
BPM, or other language.
    4. Should affected systems be required to adhere to a time limit or 
point in the host system's interconnection process (such as when a 
generator interconnection agreement (GIA) is tendered or system impact 
study data is provided by the host system to the interconnection 
customer) by which the affected system should notify the 
interconnection customer and/or host transmission provider of network 
upgrade costs?
    5. Should affected system study results be aligned with the host 
system's system impact study results to allow interconnection customers 
to have an estimate of all of their potential network upgrade costs 
prior to proceeding in the queue with an at-risk financial payment? 
Alternatively, if an interconnection customer is required to proceed 
with an at-risk financial payment or move forward with an 
interconnection agreement without having the affected system study 
results, should the affected system or host system be required to 
provide the interconnection customer with an option for a refund of its 
payment if it withdraws due to late-received affected system study 
results?
    6. Please comment on the potential for an alternative affected 
system study process in which the host system obtains the model from 
the affected system and performs the impact analysis on the affected 
system for interconnection customers itself, with the host system 
following up with the affected system to verify results. Would such an 
approach be beneficial or practicable? Would the additional analysis 
and verification add time to the interconnection process? Should the 
host system be compensated for performing the impact analysis?
    7. Should the Commission require that time be allowed to 
potentially identify and consider either alternatives to the dispatch 
assumptions or adjustments to the interconnection request that could 
mitigate the cost of a network upgrade on an affected system? If so, 
what duration of time would be sufficient?
    8. With respect to MISO, SPP, and PJM specifically, should the 
Commission require that time be allowed to potentially identify and 
consider either alternatives to the dispatch assumptions or adjustments 
to the interconnection request that could mitigate the cost of a 
network upgrade on an affected system? If so, what duration of time 
would be sufficient? Even if a common timeline is not required by the 
Commission, should MISO, SPP, and PJM nevertheless be required to build 
time into their own interconnection processes to allow for further 
consideration of affected system study results and potential mitigation 
measures as an alternative to the network upgrades included in an 
affected system study? For example, should interconnection customers in 
MISO be allowed more than 15 days

[[Page 18288]]

after receipt of affected system study results to decide to proceed to 
the next phase of the definitive planning phase (DPP)?
    9. Should MISO perform fewer affected systems studies than the 
three studies currently required as part of the three-phase DPP 
process? If so, which phase(s) in the DPP is most important to the 
analysis of potential impacts on affected systems? Should an 
interconnection customer in MISO be permitted to proceed to the next 
DPP phase even if an affected system study is not ready and therefore 
not included in the system impact study of the prior phase?

Allocation of Affected System Costs

    1. Are there improvements that could be made to transmission 
planning processes to better identify transmission projects that 
benefit host systems and/or affected systems but that are currently 
identified only in interconnection studies and affected system studies? 
If so, please explain how such improvements should be made? What are 
the benefits and drawbacks of such an approach?
    2. If study results from affected systems are significantly 
delayed, and the interconnection customer is required to proceed in the 
process without affected system study results, should the customer 
still be responsible for the full cost of an affected system upgrade? 
Should there be a time after which the affected system has ``lost its 
chance'' to have the interconnection customer be responsible for the 
network upgrade? If so, how would the affected system then address the 
need for the network upgrade?
    3. How should costs be allocated among affected system and host 
system interconnection customers in instances where a major network 
upgrade on a transmission provider's system is only identified through 
an affected system study and not identified in the host system studies? 
Should host system interconnection customers be responsible for any 
portion of those network upgrade costs? Should an interconnection 
customer needing such an affected system upgrade have the ability to 
challenge the assignment of network upgrade costs? Please also discuss 
this issue specifically in the context of the Cooper South constraint 
in SPP.
    4. Should the host system and affected system be required to 
conduct a ``least-cost alternative'' analysis for identified affected 
system upgrades? If so, please explain how that will improve the issues 
with affected systems.
    5. If the same network upgrade is required by interconnection 
requests on both a host system and an affected system, is there cost 
sharing among the interconnection customers? Does this cost sharing 
extend to lower-queued customers, whether they are host system 
customers or affected system customers?
    6. How are interconnection requests made on an affected system 
aligned with host system interconnection requests for the purpose of 
determining queue order and cost responsibility? For instance, where 
the affected system uses a cluster study approach, are interconnection 
requests external to the affected system integrated into the affected 
system's current cluster study with queue priority and cost 
responsibility equivalent to the other interconnection requests in the 
cluster?
    7. Should MISO, SPP, and PJM be required to develop a network 
upgrade construct that avoids a ``higher-queued'' penalty, whereby 
network upgrade costs are assigned to higher-queued projects (earlier 
in time) rather than to lower-queued projects (later in time)? How do 
MISO, SPP, and PJM determine whether affected system interconnection 
customers or host system interconnection customers are responsible for 
the cost of a specific network upgrade? Please list the tariff, JOA, or 
BPM provisions that may govern this process.
    8. With respect to MISO, SPP, and PJM specifically, should they be 
required to develop a unified approach to determine queue priority in 
affected systems analysis to determine cost responsibility for network 
upgrade costs?
    9. Please describe whether interconnection customers that fund 
network upgrades on an affected system and pursuant to an affected 
system study receive transmission credits, transmission rights, or any 
other consideration for funding those network upgrades on the affected 
system. Please provide any tariff or other provisions that govern this 
issue.
    10. Please describe whether interconnection customers that fund 
network upgrades on an affected system and pursuant to an affected 
system study in MISO, SPP, or PJM receive transmission credits, 
transmission rights, or any other consideration for funding those 
network upgrades on the affected system. Please provide any tariff, 
JOA, BPM or other provisions that govern this issue. Does any disparity 
in approaches between MISO, SPP, and PJM impact the interconnection 
customers and/or affected system study process? If so, how?
