(“MISO Transmission Owners”) respectfully submit this Motion to Hold this Proceeding in
Abeyance for 90 days, up to and including November 16, 2026 (“Motion”). The Motion is
necessary to permit MISO and the MISO Transmission Owners to continue the MISO stakeholder
process to develop and submit FPA section 2054 filings that address the concerns expressed in the
Show Cause Order.5 The Show Cause Order raises a number of concerns regarding the apparent
absence from MISO’s Open Access Transmission, Energy and Operating Reserve Markets Tariff
(“Tariff”) of provisions specific to the reliable interconnection, operation, and service to large loads
in the MISO region. MISO, the MISO Transmission Owners, and the MISO stakeholder
community have already undertaken significant efforts to promote the efficient integration and
reliable interconnection of large loads. These efforts address a number of the Commission’s
concerns expressed in the Show Cause Order. While the timeline would remain tight, granting this
Motion would allow MISO and the MISO Transmission Owners to respond to the remaining
concerns in a manner that recognizes the unique characteristics of the MISO region, with additional
coordination between MISO, the MISO Transmission Owners, the Organization of MISO States,
Inc. (“OMS”), and the MISO stakeholder community.
I.
EXECUTIVE SUMMARY
As MISO and its member utilities have seen, and as the Show Cause Order affirms, the
MISO region (and much of the country) is experiencing a significant influx of large load additions,
which present both significant opportunities and challenges for the region. MISO and the MISO
Transmission Owners appreciate the direction and regional flexibility the Commission provided

in the Show Cause Order to facilitate the timely and reliable addition of large loads to the MISO
transmission system without unfair cost shifts. Developing new tools and processes to
accommodate the challenges of large load integration has been, and continues to be, a primary goal
of MISO and the MISO Transmission Owners.
Prior to the issuance of the Show Cause Order, MISO, in collaboration with the MISO
Transmission Owners, OMS, and other stakeholders, identified and implemented multiple
solutions to facilitate speed to reliable power. Two already-implemented solutions are the
Expedited Resource Addition Study (“ERAS”) process to accelerate generator interconnection for
near-term resource adequacy needs, and improving the MISO Transmission Expansion Plan’s
(“MTEP”) Expedited Project Review (“EPR”) process to enable the quick study and approval of
transmission upgrades necessary for the addition of large loads.
MISO also created the Large Load Working Group (“LLWG”) in March 2026 to provide a
dedicated and consolidated stakeholder forum to prioritize and focus efforts to both identify critical
issues and develop corresponding solutions to integrate large loads reliably and cost effectively.6
The LLWG, like other MISO stakeholder processes, allows for the consideration of issues and
solutions developed not only by MISO staff but also by stakeholders. The stakeholder issue
submission process in the LLWG is an important element for MISO’s development of solutions
for effectively serving large loads because, as the Commission is aware,7 stakeholders are well

The MISO Steering Committee approved creation of the LLWG in a special meeting on March 16, 2026.

situated to identify solutions to some of the current challenges for large load integration. MISO
affords equal consideration and deliberation in the LLWG to recommended solutions identified by
all stakeholders.
Through this collaborative stakeholder forum, MISO has developed a prioritized work plan
to accelerate consideration of the challenges presented by the rapid growth of large load in the
MISO region. The Show Cause Order referenced many of the items in the MISO workplan, which
helps reinforce those efforts and provides further guidance that will help drive timely solutions.
As part of this work plan, and as described in more detail below, MISO and stakeholders
have developed designs and/or draft Tariff language for several additional solutions, including: (1)
the Zero Injection Generator Interconnection Agreement (“ZGIA”) and related study process,
which will provide a Tariff-defined process for co-location of generation and load; (2) a new
definition of large load; (3) interconnection reliability requirements to facilitate the reliable
interconnection and operation of large loads; (4) a firm step up service to provide a pathway to
energize a portion of a large load prior to full interconnection and upgrade completion; and (5) a
parallel study process for large load and generation resources (i.e., Load Addition and Resource
Study process or “LARS”), which was discussed in MISO’s Informational Report on Resource
Adequacy filed in this docket.8

MISO and the MISO Transmission Owners acknowledge that several issues identified in
the Show Cause Order were not in MISO’s original workplan, as the initial workplan reflected the
more pressing and needed solutions, and therefore, respectfully request a 90-day abeyance to
recalibrate the workplan and work through the stakeholder processes to develop regionally tailored
FPA section 205 filings to revise the Tariff to address the issues identified in the Show Cause Order.
The current, imminent compliance deadline in the Show Cause Order effectively prohibits the full
development and robust consideration of any potential stakeholder solutions to integrating large
loads. The requested abeyance will afford stakeholders the necessary time to identify and discuss
creative solutions and will then afford MISO and the MISO Transmission Owners the time
necessary to formalize any Tariff and business practice revisions necessary to implement such
solutions consistent with the guidance provided in the Show Cause Order.
As stated above, the guidance from the Commission in the Show Cause Order provides an
opportunity for MISO and the MISO Transmission Owners to move these new initiatives forward
quickly with solutions leveraging MISO and the MISO Transmission Owners section 205 filings
rights. MISO and the MISO Transmission Owners are committed to bringing FPA section 205
solutions to the Commission as contemplated in the Show Cause Order in a timely, pragmatic, and
responsible manner consistent with the needs of the region.
II.
MISO SHOW CAUSE PROCEEDING
The Show Cause Order identifies an unprecedented increase in requests for transmission
service to serve large load, as well as the growing interest in the co-location of loads with
generation facilities (i.e., co-location arrangements), while acknowledging the challenges
associated with providing the transmission service to reliably serve the ongoing influx of large
PDF page 6

loads.9 The Show Cause Order states that there is a lack of clarity and consistency in Regional
Transmission Organization or Independent System Operators’ tariffs regarding the rates, terms,
and conditions of service that apply to flexible large loads, co-location arrangements, load with
behind the meter generation, and generating facilities with electrically proximate large load or co-
located load.10 Ultimately, the Show Cause Order directs MISO and the MISO Transmission
Owners to:
(1) show cause as to why the Tariff remains just and reasonable and not
unduly discriminatory or preferential without provisions addressing:
(a) the application process, study procedures, and ongoing
operational requirements that apply to Eligible Customers seeking
transmission service on behalf of large loads;
(b) additional transparency concerning the Network Upgrade costs
to provide transmission service to Eligible Customers on behalf of
large loads, a pro forma cost recovery agreement between MISO,
the relevant transmission owner, and Eligible Customer taking
transmission service on behalf of the large load to mitigate the risk
of cost shifting among transmission customers, and a mechanism to
ensure such payments are appropriately credited toward
transmission owners’ transmission revenue requirements consistent
with the Commission's cost-of-service regulations;
(c) the rates, terms, and conditions of service that apply to co-
location arrangements;
(d) transmission services that reflect Eligible Customers taking
transmission service on behalf of co-located loads, load with
behind the meter generation, and flexible large loads that are
willing and able to limit their use of the transmission system under
certain conditions; and
(e) the rates, terms, and conditions of service applicable to
interconnection customers serving electrically proximate large load
or co-located load; or

(2) explain what changes to the Tariff would remedy the identified concerns
if the Commission were to determine that the Tariff has in fact become
unjust and unreasonable or unduly discriminatory or preferential and,
therefore, proceeds to establish a replacement Tariff.11
The Commission ordered that MISO and the MISO Transmission Owners address these
issues in a filing due within 60 days; however, the Commission stated that it would consider
requests from MISO and the MISO Transmission Owners to hold the proceeding in abeyance, for
up to 90 days, to provide MISO and the MISO Transmission Owners time while they work through
the stakeholder processes to develop FPA section 205 filings to revise the Tariff to address the
issues raised in the Show Cause Order.12
III.
REQUEST FOR ABEYANCE
The Show Cause Order demonstrates the high priority the Commission has placed on
ensuring that jurisdictional regional grid operators work quickly to meet the challenge of
integrating large loads to support the artificial intelligence and manufacturing related national
security and economic opportunity goals. Notwithstanding the need for speed, the Commission
invited MISO and the MISO Transmission Owners to seek to hold the show cause proceeding in
abeyance, for up to 90 days, to provide MISO and the MISO Transmission Owners time while they
work through the stakeholder process to develop FPA section 205 filings to revise the Tariff to
address the issues raised in the Show Cause Order.13 MISO and the MISO Transmission Owners
agree that an aggressive timeline is needed to address these issues, and that the breadth and
complexity of the concerns raised in the Show Cause Order will require a more expedited
stakeholder process and feedback loop than is typical before filing solutions with the Commission.

MISO and the MISO Transmission Owners are committed to undertaking that process in good
faith with the expectation that the Commission will be presented with a comprehensive set of
section 205 filings addressing the issues identified in the Show Cause Order.
MISO and the MISO Transmission Owners appreciate the important role that states play in
the MISO region, especially in managing the ultimate retail costs to customers and affordability.
It is also because of the MISO states’ continued focus on resource adequacy that the MISO region
is not facing an immediate crisis related to large load integration as has been experienced in other
parts of the nation. MISO and the MISO Transmission Owners are committed to continued
collaboration with the states as solutions are finalized and brought before the Commission.
Given the volume of work to be accomplished and the need to engage stakeholders, MISO
and the MISO Transmission Owners respectfully request that the Commission grant a 90-day
abeyance to allow MISO and the MISO Transmission Owners to bring regionally tailored solutions
to the Commission to address the issues identified in the Show Cause Order. The abeyance will
allow MISO and the MISO Transmission Owners the opportunity to leverage the LLWG further
to collaborate with the states and stakeholders to develop robust, durable solutions to meet the
needs in the MISO region. Importantly, MISO is not starting from scratch—the current MISO
stakeholder process has already developed several prioritized proposals to address large load
integration, as further described below. MISO and the MISO Transmission Owners are confident
that the abeyance approach will provide the most successful path forward to achieve the
Commission’s desired outcomes to ensure the integration of large loads in an efficient, reliable,
and affordable manner.
Although MISO, the MISO Transmission Owners, the OMS, and stakeholders have been
working on several speed to power initiatives, the 90-day abeyance requested herein is essential to
PDF page 9
9
permit MISO and the MISO Transmission Owners, in collaboration with member states and other
stakeholders, to adjust planned solutions to fully address the Commission’s directions and, where
necessary, to develop additional Tariff revisions responsive to the Show Cause Order. The
challenges and opportunities presented by large loads are multi-faceted and implicate numerous
parts of MISO’s Tariff. Therefore, while speed is important, it also is critical to ensure that
individual solutions align properly with each other and with existing MISO procedures. This is a
complex task.
Good cause exists to hold the show cause proceeding in abeyance. MISO has established
a dedicated stakeholder forum to address the issues identified in the Show Cause Order associated
with the reliable integration of large loads. Holding the show cause proceeding in abeyance will
promote administrative efficiency, allow for more carefully-crafted solutions, and avoid
unnecessary litigation of matters that would be more appropriately addressed through the ongoing
MISO stakeholder process. Ultimately, granting the abeyance will not prejudice any party, as all
parties will have an opportunity to participate in MISO’s public stakeholder process and intervene
in future FPA section 205 filings.
IV.
COMPLIANCE PLAN
A.
Overview of Compliance Approach and FPA Section 205 Filings
MISO and the MISO Transmission Owners will address the issues raised in the Show
Cause Order through a series of FPA section 205 filings to be submitted during the abeyance
period.14 Below is a description of the FPA section 205 filings that MISO and the MISO
Transmission Owners are currently contemplating. As shown below, some proposals have already

joins in that filing. This will be determined as each subsequent section 205 filing is developed.
PDF page 10
10
undergone significant stakeholder vetting and as such, will be filed prior to the end of the 90-day
abeyance. Other proposals are still in their infancy and may require the entire 90-day abeyance.
First, MISO expects to submit tariff changes establishing a new Zero Injection Generator
Interconnection Agreement (“ZGIA”) and related study process to facilitate faster resource
additions when those resources are designated to serve load at the same substation, thereby
accelerating the addition of generation resources that have little or no impact on the Transmission
System. With these proposed Tariff changes, the ZGIA will partly address several of the issues
raised by the Commission related to co-location of generation and large loads by proposing a
permanent solution for generation resources seeking to interconnect to the Transmission System
at the same substation as an associated load.15 MISO expects to submit the ZGIA filing by the end
of August.
Second, MISO anticipates submitting Tariff changes establishing new large load
Interconnection Reliability Requirements (“IRR”). The proposed IRR Tariff changes will establish
operational requirements for transmission customers serving large loads to ensure visibility and
reliable operation of the Transmission System.16 Specifically, the IRR filing will include
requirements for large loads to provide basic facility data, modeling, telemetry, and forecasting
information.17 In addition, the proposed IRR Tariff changes will provide detail regarding Phasor
Measurement Unit (“PMU”) requirements, as well as requirements for ramp and ride-though for
certain types of large loads.
15 See SCO at PP 58, 94, 113, 115, 117 and 118.
16 See SCO at P 57; id. at P 64 (preliminarily finding that MISO’s Tariff appears to be unjust and unreasonable
because it lacks provisions addressing ongoing operational requirements for transmission customers taking
transmission service on behalf of large loads).
17 See SCO at P 64 (stating that MISO’s Tariff does not require transmission customers to provide MISO hourly
forecasts, telemetry data, and other data to ensure sufficient visibility or specify requirements for maintaining
communication channels between MISO and the transmission customer on behalf of the large load).
PDF page 11
11
Third, at the July 16, 2026, LLWG meeting, MISO presented and stakeholders accepted a
formal issue submission and conceptual design for a load addition and resource study (“LARS”)
process.18 LARS will assess the transmission infrastructure needed to meet new large loads and
new generation in an efficient process that can be executed on a shorter timeline, further
supplementing the opportunities available for members to facilitate new large spot loads
effectively. This process is expected to position MISO and its members to ensure resource
adequacy and protect customers from unnecessary investments relating to the uncertainty of spot
large load siting.
More specifically, LARS will analyze generation and transmission using the same study
assumptions applied in the standard generator interconnection process and MISO’s MTEP. The
studies will be run in parallel, and will finish at approximately the same time—within 120 days—
with the load/transmission model incorporating both the planned generation and planned load.19
LARS, as currently conceived, will address similar issues to those the Show Cause Order identified
related to interconnection customers serving electrically proximate large load or co-located load.20
MISO will continue to develop the LARS process through the LLWG and expects to submit the
LARS filing by November 16, 2026, or earlier, if feasible.
Fourth, MISO has presented to the LLWG initial concepts to accommodate flexible large
loads including a firm transmission service step-up option. A firm step-up option was initially
18 The concepts discussed herein as the LARS process were referred to as the “Generation and Large Load
Alignment” process at the July 16, 2026, LLWG.
19 MISO included a description of this Joint Study Process in its Informational Report submitted in this docket on
July 20, 2026.
20 SCO at P 113 (preliminarily finding that MISO’s Tariff may be unjust and unreasonable because it does not
contain provisions that will allow an interconnection customer to seek the generator interconnection service(s)
that reflects the operational dynamics of serving either: (1) an electrically proximate large load; or (2) a co-
located load, that has a high peak load (i.e., large co-located loads that are 50 MW or greater)).
PDF page 12
12
discussed with stakeholders at the April 20, 2026, LLWG and again at the June 10 and July 16
LLWG meetings, including a request for stakeholder feedback on proposed Tariff revisions
presented at the LLWG on July 16, 2026. MISO will address stakeholder feedback on the firm
transmission service step-up Tariff revisions at the August 2026 LLWG meetings. MISO expects
to make a section 205 filing proposing Tariff revisions incorporating the firm service step-up
option by November 16, 2026, or earlier, if feasible.
Fifth, at the July 16, 2026, LLWG, MISO presented a formal issue submission and concepts
for a non-firm large load service option intended to address the issues the Commission identified
in the Show Cause Order relating to the unique operational characteristics of large loads that are
willing and able to limit their energy withdrawals under certain conditions and the effect on the
need for certain Network Upgrades.21 The LLWG voted to accept the issue submission and
continue discussions related to the development of non-firm large load service options. MISO will
continue to develop these service options through discussions at the August 2026 LLWG meetings.
Finally, MISO and the MISO Transmission Owners are working together22 to develop
additional solutions, processes, and services to address the balance of the Commission’s concerns
identified in the Show Cause Order. These include, among other things, (a) the application process,
study procedures (including evaluating alternative transmission technologies), and ongoing
operational requirements that apply to Eligible Customers seeking transmission service on behalf
of large loads; and (b) additional transparency concerning the Network Upgrade costs and cost
shift concerns.23 MISO will present concepts and proposed Tariff revisions to the LLWG for
21 SCO at P 60, see also, SCO at PP 102, 104.
22 To the extent the Commission’s concerns address the rates, terms and conditions of Transmission Service and
may implicate rate design and Transmission Owner revenue requirements, the FPA section 205 filings
addressing these issues are expected to be joint filings with the MISO Transmission Owners.
23 See SCO at P 33.

discussion and formal stakeholder feedback requests as they are developed in anticipation of a
November FPA section 205 filing to address any Commission directives not addressed in a prior
FPA section 205 filing.
B.
Process and Schedule for Stakeholder Input
To facilitate further stakeholder discussion and formal feedback cycles on proposals to
address the Commission’s concerns expressed in the Show Cause Order, MISO has scheduled a
series of LLWG meetings during the requested abeyance period. While the following LLWG dates
have been established, MISO is committed to working with stakeholders to address the issues in
the Show Cause Order and will call special meetings of the LLWG if necessary. Currently, the
LLWG is scheduled to meet six times between the date of this filing and the end of the requested
abeyance period including:
Wednesday, August 12, 2026
Thursday, August 27, 2026
Wednesday, September 23, 2026
Thursday, October 8, 2026
Thursday, October 29, 2026
Monday, November 16, 2026
A detailed management plan outlining the specific agenda for these meetings is located on MISO’s
website and will be updated regularly.24
24 The following is the July 31, 2026, version of the LLWG management plan:
https://cdn.misoenergy.org/20260812%20LLWG%20Item%2001d%20Management%20Plan772569.pdf (last
visited August 3, 2026). MISO notes that the LLWG management plan will be revised from time to time and
updated versions will be posted on MISO’s website.

V.
REQUEST FOR SHORTENED COMMENT PERIOD AND EXPEDITED TREATMENT
MISO and the MISO Transmission Owners respectfully request that the Commission issue
an order granting the requested 90-day abeyance on an expedited basis by August 14, 2026.
Prompt action on this Motion will provide certainty to MISO and its stakeholders regarding the
need to submit a response to the Show Cause Order by August 17, 2026, and avoid the expenditure
of time and resources on preparing filings that may prove unnecessary. With such certainty, MISO
and its stakeholders can confidently spend critical time and resources developing the FPA section
205 filings discussed herein.
To enable the Commission’s consideration of this Motion on an expedited basis, MISO and
the MISO Transmission Owners also request that the Commission establish a 5-day comment
period for this Motion—i.e., by August 10, 2026. The Commission may shorten or eliminate
answer periods altogether for good cause shown.25 Good cause exists to establish a 5-day answer
period and grant expedited treatment of this Motion because the Show Cause Order’s compliance
deadline is fast approaching and parties need certainty regarding the compliance timeline.
VI.
CONCLUSION
For the reasons set forth above, MISO and the MISO Transmission Owners respectfully
request that the Commission: (i) grant this Motion to hold this proceeding in abeyance for a period
of 90 days starting August 17, 2026, to allow time for MISO and the MISO Transmission Owners,
where applicable, to develop and submit FPA section 205 filings to address the issues identified in
