LIMITED PROTEST OF GOOGLE LLC
Pursuant to Rule 211 of the Rules of Practice and Procedure of the Federal Energy
Regulatory Commission (“Commission”),1 Google LLC (“Google”) submits this limited protest
of Midcontinent Independent System Operator, Inc.’s (“MISO”) proposal to establish a Large
Load Addition Resource Study (“LARS”) process.2 Google commends MISO for working
proactively to address the concerns that the Commission identified in the Large Load Show Cause
Order.3 The concept underlying LARS is a particularly important one that is worth prioritizing,
and it is a concept that Google continues to strongly support. Studying new large loads together
with paired generation resources that will serve those loads will maximize the use of existing
infrastructure and minimize strain on the grid,4 which will, in turn, accelerate interconnection

timelines and reduce the cost to serve both the load and the generation.5 Again, Google supports
the intent and conceptual direction of LARS.
Nevertheless, Google is filing a limited protest because MISO has filed LARS without
accompanying and necessary protections against cost shifting, which prevents the Commission
from finding that LARS is just and reasonable. The lack of cost shifting protections is especially
concerning because, despite the benefits—especially speed to power—that LARS would promote,
it is structured in a way that threatens Google’s ability to meet its foundational commitment to
ensuring that other retail customers do not bear the costs of serving its data centers, including
through the Ratepayer Protection Pledge.6 Our concern is two-fold. First, LARS upgrades needed
to address violations caused by large loads—or caused by the load and generation together—are
classified as Baseline Reliability Projects (“BRPs”) or “Other” projects. Under current rules, the
costs of those project types are recovered from all network customers in a Transmission Pricing
Zone. Second, if LARS generating facilities/load end up relying on transmission capacity that
other projects were also relying on—a scenario MISO refers to as “overallocation”—MISO would
address the resulting transmission constraints through a “future MTEP project,” the costs of which
are “likely” to be borne by “the load within the transmission pricing zone where the transmission
upgrade is required.”7 Under either scenario, MISO could end up saddling residential customers
and other existing commercial customers with increased rates resulting from the costs of
transmission facilities needed to interconnect and serve large loads. And while MISO indicates

needs at the lowest cost”).

that it will file a pro forma cost shifting agreement in November,8 the details of that agreement
and how it will protect against cost shifts are open questions, which the Commission cannot simply
assume away.
To be clear, Google supports both the concept underlying LARS, which will improve speed
to power and transmission planning, and provisions that protect other network customers against
cost shifting. The issue, however, is that MISO has decoupled LARS’s speed to power provisions
from cost shifting protections. By timing and sequencing its filings in this way, MISO has made
it impossible for the Commission to determine that the LARS proposal is just and reasonable.
Google remains actively engaged in the ongoing MISO stakeholder process and is hopeful that the
anticipated November filing will include the necessary guardrails to hold other network customers
harmless, at which point the significant benefits of LARS may be realized without the potential
for cost shifting.
Accordingly, to address the cross-subsidization concerns outlined above, the Commission
should either reject LARS with guidance indicating that it needs to be filed concurrently with
procedures to prevent cross-subsidization or, in the alternative, accept and suspend the proposal,
until it can be evaluated alongside any necessary customer protection measures, including the
contemplated pro forma cost shifting agreement. Regardless of the avenue selected by the
Commission, Google supports future implementation of a refined LARS process that mitigates the
identified cost-shifting concerns, while still enabling the benefits of a targeted, combined process
for studying a large load and its contractually paired generation together.
In addition, MISO must also continue to refine and improve its principal interconnection
process, the Definitive Planning Phase (“DPP”), so that all generation resources in MISO—not

just those paired with large loads—can interconnect on a reasonable timeline. A viable DPP that
timely interconnects large quantities of new generation is the single most important step that MISO
can take to continue ensuring resource adequacy. On that score, MISO recently took a step in the
right direction with its legacy queue acceleration proposal, which is aimed at clearing the DPP-
2022 Cycle and preventing “endless” Phase III system impact study restudies for all future DPP
cycles.9 As Google has previously stated, “fixing the sluggish timelines in the DPP is a more
durable and lasting solution to MISO[’s] interconnection challenges than an endless series of
shortcuts, even if some of those shortcuts are merited for the foreseeable future,”10 and Google
therefore urges MISO to continue refining the DPP process even as it continues to develop a
workable interconnection pathway for paired load and generation.
A. The LARS Proposal Opens the Door to Shifting the Costs of Serving LARS Pairs
onto Other Customers and Future MTEP Cycles
Customers like Google could be prevented from using LARS without violating their
Ratepayer Protection Pledge commitments. That is because, under LARS, MISO will study the
load and generation in a pair and “any common violations that show up in the generation and load
studies [will be] assigned to [BRPs] and Other project types.”11 Only the violations specifically
caused by the generator’s interconnection are assigned to the generator. Under the MISO tariff,
the costs of BRPs and “Other” projects are recovered through Attachment O by the Transmission
Owner developing the project, for the portion of the project located in that Transmission Owner’s

pricing zone.12 This means that the cost of transmission upgrades needed to serve a LARS large
load—or to address violations caused jointly by the LARS load and its paired generation—will
flow into rates paid by other network customers in the zone, and—under current rules—could raise
rates paid by residential or other commercial customers. Allocating costs in this way could prevent
Google and other signatories from honoring their pledge to “pay for all new power delivery
infrastructure upgrades required to service their data centers, including adequate network upgrade
costs to ensure that these expenses are not passed on to the ordinary household.” 13
MISO states that the transmission customer serving the large load “remains responsible for
the identified BRPs and Other assigned projects.”14 But MISO fails to explain how the tariff
provisions proposed in LARS and that are now before the Commission will ensure that result, and
therefore hold other network customers harmless. Instead, MISO simply states that cost impacts
from the load study “will be assigned to Baseline Reliability Projects and Other type projects,”
with “cost responsibility flowing from such designation under existing rules.”15 But under existing
rules, that responsibility flows indiscriminately to the Transmission Pricing Zone, without
necessary “hold-harmless” protections for other network customers. Without an explanation on
the record, there is no way to ensure that LARS adequately guards against cost shifting, and the
filing cannot be deemed just and reasonable.16

In addition, LARS could shift costs onto residential customers and other existing
commercial customers by relying on the MTEP process as a backstop to develop projects needed
to resolve transmission issues caused by LARS pairs. MISO explains that if it allocates headroom
to a LARS generator that has also been allocated to a DPP project—a phenomenon that MISO
calls “overallocation”17—then any resulting constraints caused by that overallocation “will be
formalized in a future MTEP project.”18 Put differently, residential and other commercial
customers could be left holding the bag for transmission projects needed to interconnect LARS
generators any time MISO “overallocat[es]” available headroom.
That too represents an unacceptable risk of cross-subsidization. That is particularly so
given that LARS’s design creates the very real risk of overallocation because ongoing DPP cycles
do not include LARS requests and the LARS studies do not include DPP projects before they have
signed Generator Interconnection Agreements.19 As a result, each process is based on an
incomplete snapshot of the transmission system and how it will operate in practice, which increases
the likelihood that the LARS and DPP processes will produce incompatible results. MISO would
not, however, reconcile the DPP and LARS study processes until after both are complete,20 and, if
the cumulative impacts of the two separate studies create constraints not identified in either, the
upgrades necessary to resolve those constraints will be deferred to the MTEP process.
That result would be unjust and unreasonable and inconsistent with Google’s customer-
protection commitments, including the Ratepayer Protection Pledge. The Commission should
17 MISO never explains what it means by “overallocation,” but it appears to refer to double allocating headroom
to projects in both the DPP and in LARS.

require MISO to adopt mechanisms that protect against this result before concluding that LARS is
just and reasonable. For example, LARS could be modified to use more conservative
assumptions—e.g., accounting for DPP requests that have reached an advanced stage, such as
Decision Point II, or explicitly stating that concurrent Large Load study requests (i.e., those in the
same project review cycle) are likewise included in the LARS study assumptions—so that MISO
avoids “overallocating” transmission headroom. This, in turn, would ensure that large load
customers and their paired generators internalize the risk of inaccurate load and generation studies
rather than leaving residential customers on the hook for transmission infrastructure needed to
serve large loads.21 Together, rigorous study assumptions and high commercial readiness
requirements would allow MISO to study LARS requests based on a more accurate snapshot of
the grid, which would protect existing customers from bearing the costs of transmission projects
pushed into the MTEP process. Although, as noted below, a sufficiently rigorous agreement to
prevent cost shifting could address these concerns, the absence of any such agreement for the
Commission to review in the record of this proceeding prevents the Commission from relying on
it to find the proposal just and reasonable.
B. Without the Pro Forma Cost Shifting Agreement, the Commission Cannot Find
LARS Just and Reasonable
MISO’s forthcoming pro forma cost shifting agreement could address some of the cost
allocation issues identified above. But the Commission cannot know for certain until MISO files
that agreement with the Commission. MISO states that “a pro forma cost shifting agreement will
21 Further, resolving LARS-driven constraints with future MTEP projects is, at the very least, in tension with the
premise of LARS. Indeed, as MISO itself explains, one benefit of a coordinated study is that it identifies an optimized
set of upgrades. See id. at 15. But if LARS-driven constraints are instead discovered later and resolved through future
MTEP projects, the resulting upgrades are developed in the piecemeal fashion that holistic planning is meant to avoid.

need to be executed and any new terms in transmission services agreements will need to be met.” 22
But that statement raises more questions than it answers. Without information on what the pro
forma will cover or how it will work, the Commission cannot be sure that it will, in fact, work to
protect residential and other commercial customers from bearing at least some of the costs
associated with new large loads. Accordingly, even though MISO states that the cost shifting
agreement will be submitted in a separate section 205 filing by November 16, 2026, and that LARS
“can be implemented based on the Tariff revisions filed herein and need not await these future
filings,”23 the Commission cannot determine that LARS is just and reasonable because the record
lacks such a key piece of the puzzle.24
That leaves the Commission with two options to address the cost-shift concerns. It could
reject the LARS proposal outright with direction to MISO that if it refiles LARS it must contain
adequate protections against cost shifting, including any pro forma agreement. Alternatively,
because MISO states that the pro forma cost shifting agreement will be filed in November, the
Commission could accept and suspend the proposal and consolidate it with the MISO Large Load
Show Cause proceeding, in order to evaluate the proposal together with the cost shifting
agreement. Either way, Google urges the Commission to direct MISO toward future
implementation of a refined LARS process that mitigates the identified cost-shifting concerns,
while enabling the benefits that such a process would deliver.

C. LARS Opens the Door to Undue Discrimination
Finally, Google is concerned that LARS opens the door to undue discrimination and could
undermine core open access principles by making load-serving entities (“LSEs”) the gatekeepers
of the LARS process. Under MISO’s proposal, LARS applications must be submitted through a
designated LARS Associated Transmission Customer, which MISO indicates is typically the LSE.
This appears to give LSEs discretion to determine whether and under what circumstances to submit
a LARS application because it gives the LSE the central role of submitting applications, with no
guardrails should an LSE simply decline to submit an application on behalf of an independent
generator. This concern is particularly acute given that many of the states within MISO’s footprint
are vertically integrated, and vertically integrated utilities have a structural incentive to favor their
generators over those that are independently owned.25 While Google recognizes that LSEs have
an obligation to serve load and are responsible for submitting load study requests, making LSEs
gatekeepers for the LARS process will unnecessarily restrict supply available to serve new large
loads, particularly where independent generators have direct offtake arrangements with loads.
Google encourages FERC to provide targeted guidance to MISO to modify the proposal to include
protections providing that all forms of generation, including independent generation, have
nondiscriminatory, direct access to the expedited generation interconnection study process under
LARS. This could include requirements to file a LARS application that meets objective criteria,
an ability for independent generators to secure Commission resolution of disputes with the relevant
LSE, similar to how the Commission resolves unexecuted generator interconnection agreements,
or an alternative mechanism that addresses these concerns.
25 Cf. Am. Clean Power Ass’n v. FERC, 54 F.4th 722, 728 (D.C. Cir. 2022) (explaining that “a majority of
MISO-region transmission owners also generation facilities,” which gives rise to a risk that those vertically integrated
transmission owners could engage in undue discrimination).
