Introduction
The Consumers Energy Company’s integrated resource plan has generated
controversy, some merited and some not. The controversial issues include, among
other things, the Company’s proposed financial compensation mechanism, its
decision not to purchase all of the capacity in its interconnection queue, its decision
to retire certain coal units but not others, and the need for procedures to govern the
competitive-bidding process and requests for proposals. Despite this controversy,
the parties are aligned on several issues. For instance, most parties support the
Company’s innovative competitive-bidding proposal if the solicitation process is
inclusive, unbiased, and transparent. Most parties also oppose the Company’s
request for an incentive on power purchase agreements that it enters in the future.
Staff falls into both camps. It supports competitive bidding, but it opposes any
financial incentive that is more than needed to spur this process. Staff’s proposed
alternative to an incentive—to allow the Company to own 50% of the generating
assets it procures and contract for the other 50% through competitive solicitations—
would drive down prices and facilitate transmission planning.
As for the other issues, although Staff acknowledges that the Company’s
capacity outlook has changed slightly since the Company first filed its plan, Staff
still agrees with the Company’s decision not to purchase all of the capacity in its
interconnection queue. Instead, the Company should use its proposed competitive-
bidding process to slowly secure additional supply- and demand-side resources in
small increments that allow the Company to adapt as circumstances change. Staff
4
agrees with the Company’s decision to retire Karn Units 1 & 2 in 2023 but not to
retire Campbell Units 1 & 2 early (subject to change in a future plan case). Finally,
Staff agrees that the Commission should implement uniform standards on best
practices for competitive bidding and requests for proposals. But the Commission
should implement interim standards that allow utilities to move forward with RFPs
in the meantime.
Response to Consumers
Consumers should be commended for proposing a plan to procure solar
generation through a competitive-bidding process, to retire old coal generating
units, and to replace the lost capacity with demand response, energy waste
reduction, and conservation voltage reduction. Despite filing a cutting-edge plan,
the Company requested an extravagant incentive that violates the law by exceeding
the Company’s weighted average cost of capital. (Staff’s Revised Initial Br, pp 66-
67, 80; Staff’s Reply Br, pp 3–5.) The Company’s proposed incentive is also more
than it needs to persuade it to enter into power purchase agreements. If the
Commission decides that the Company needs an incentive, it should approve one
that is high enough to spur competitive bidding, but no higher. (See Staff’s Revised
Initial Br, p 77-81.) Staff’s proposed 50-50 split—either in lieu of an incentive or
combined with a much lower incentive—is also a good alternative that would spur
competition, drive down prices, and improve transmission planning.
Staff opposes the Company’s attempt to include operations and maintenance
(O&M) expenses, the unrecovered book value of Karn Units 1 & 2, and
5
decommissioning costs in its plan because they are outside the statutory scope of
this case.
Staff stands by its proposed 50-50 resource split, but it should not be paired with the Company’s proposed financial compensation mechanism.
While Consumers continues to support its originally proposed financial
compensation mechanism, the Company has clarified that alternatives would be
acceptable in the right circumstances, meaning that it could support, with some
changes, proposals presented by Staff and other parties. (Consumers’ Exceptions, p
91.) Staff is pleased by this development because it was not clear on the record that
the Company would accept anything less than its proposal. The ALJ reasonably
concluded, based on the record, that the Company was taking an all-or-nothing
approach to its proposed financial compensation mechanism. (PFD, p 266.) But the
Company’s Exceptions are evidence that this is no longer the case and that it is
willing to accept something less than it proposed. Unfortunately, however, even the
Company’s compromise position is too expensive for ratepayers.
The Company’s compromise position is better than its original position but still too expensive for ratepayers.
Staff witness Paul Proudfoot proposed that, in lieu of a financial incentive,
the Commission could allow Consumers to own 50% of the generating assets it is
proposing to procure and contract for the other 50% through its competitive bidding
proposal. (9 TR 2564-2566.) Mr. Proudfoot testified that this construct would
continue “the fifty percent limitation on company-owned resources that was
6
included in [2008] PA 295,” which “led to increased competition and drove prices
down for customers in Michigan, including lower prices for Company-owned
renewable resources.” (9 TR 2564.) For the 50% of Company-owned generation, the
Company could, and hopefully would, competitively bid its engineering,
procurement, or construction contracts, which would further drive down costs.
In addition to the price benefits, Staff’s 50-50 proposal has other benefits as
well. Mr. Proudfoot said, “Allowing the Company to own a portion of the new
resources will also provide the Company with greater control over the maintenance
and operation of the equipment, greater insight into the performance of the
equipment, and better equip the utility to forecast the output from the solar
resources.” (9 TR 2566.) If the Company owns up to 50% of its resources, then it
will have early knowledge of the location of these resources. By contrast, when the
Company procures resources through requests for proposals (RFPs) and competitive
bidding, the Company does not learn the location of resources until much later in
the process. Knowing the location early allows the Company to better coordinate
generation and transmission planning going forward. (Staff’s Reply Br, pp 12–13.)
Staff agreed with METC that coordinated generation and transmission
planning—using IRP planning information rather than less certain information
from interconnection queues—is needed to develop a more efficient and robust
transmission grid. Coordinated planning could also help 1) ensure that resources
are interconnected in an orderly fashion at optimal locations, 2) achieve the right
balance between transmission and generation investment, and 3) inform the
7
Company’s RFP process. (Staff’s Reply Br, p 12.) While sourcing all future
resources from RFPs or competitive solicitations may lower costs for resources, it
may also hamper the transmission and distribution systems and increase costs.
Staff’s 50-50 proposal combines the benefits of coordinated generation and
transmission planning with the cost benefits of competitive solicitation. This is why
Staff continues to support the 50-50 split in lieu of a PPA incentive or in
combination with a much lower incentive. Consumers too is receptive to this
proposal, but it has suggested that the 50-50 split should be coupled with “the FCM
methodology proposed by MEC witness Jester, which can be calculated at
9.27%.” (Consumers Exceptions, p 92.) Although this compromise proposal is an
improvement over its originally proposed incentive, it is still too expensive for
ratepayers.
With Staff’s 50-50 proposal, there is no need for an incentive—certainly not a
high incentive. The alternative incentives that Staff proposed, even without the 50-
50 split, were much lower than the 9.27% that Consumers is now proposing as an
alternative together with the 50-50 split. (See Staff’s Revised Initial Br, pp 66–81.)
But Staff’s 50-50 proposal would significantly mute the need for a financial
incentive. Considering the Company’s PPAs soon to expire, the Company’s plan
would not increase the total amount of purchased power in its generation portfolio
for several years. So in the short term, the Company’s plan would maintain the
status quo, and the Company does not need an incentive to maintain the status quo.
8
While Consumers characterizes its IRP as the replacement plan for Karn
Units 1 & 2 in 2023, the IRP is also replacing the Palisades PPA, which is a major
source of energy and capacity, not to mention the other PPAs that will be expiring
not long afterward. Company witness Blumenstock testified, “The Company’s PPA
with Palisades will terminate on April 11, 2022. . . . The large decline in surplus
capacity in 2021 is attributed to the loss of 765 ZRCs from the Palisades PPA.” (6
TR 248.) The following chart from the Company’s IRP report shows the Palisades
retirement and other major upcoming generation replacements and retirements:
(Exhibit A-2, p 7.)
As this chart shows, before the Company retires all of its coal units in the 2030s and
2040s, it is planning to replace large PPAs as well as significant amounts of
Company-owned generation. (Exhibit A-2, p 7.) The ratio of PPAs to Company-
owned resources would be similar to acquiring 50% of new resources as PPAs
through competitive bidding and 50% as Company-owned generation.
9
The 50-50 split proposal is much closer to the status quo than Consumers
portrays it. Company witness Sri Maddipati, for example, said that Staff’s 50-50
proposal would shift “the Company’s owned generation from nearly 70% to 50% over
time [and] would still be a dramatic shift.” (7 TR 753.) In the long-term, the 50-50
split would shift generation as described, but it would take the Company many,
many years to get there. In the short and intermediate term, the 50-50 proposal
could lead the Company to replace major PPAs with 50% Company-owned
generation, largely maintaining the status quo. Since the Company does not have a
financial compensation mechanism today, a plan that incorporates a 50-50 split and
maintains the status quo should not be coupled with anything more than a very
small incentive, if any incentive at all.
In sum, there is no longer a need to reject the Company’s plan believing that
it will not accept a plan with an incentive lower than the one it proposed. The
Company has shown that it will accept less. This may even be true of the
Company’s compromise position. The Company might accept an incentive lower
than 9.27% if it is in combination with a 50-50 resource split, which is why Staff
continues to support the 50-50 split with no incentive or a lower one.
As Staff proposes it, the 50-50 split has a lot to offer. The same 50-50 split
that began with Act 295 has succeeded in reducing costs. It could also help Staff,
MISO, utilities, and other interested stakeholders coordinate generation and
transmission planning. But given the significant PPAs that the Company plans to
10
replace in the next decade, if Staff’s 50-50 proposal is coupled with an incentive, it
should in no circumstance be higher than Staff’s proposed incentive.
The Company’s original proposal is unlawful.
The Company continues to advocate for a financial compensation mechanism
that is tied to imputed debt. It argues that its proposed incentive is needed to
“fairly incorporate the impacts of imputed debt caused by PPAs so that the costs are
visible at the time of procurement and so that there is a built-in vehicle for recovery
of those costs.” (Consumers’ Exceptions, p 67.) But imputed debt should be
considered in a rate case together with the Company’s entire cost of capital. A 2008
Brattle Group report that the Company relied on to support its proposed incentive
reveals that most states that consider imputed debt do so in a general rate case.
Staff witness Bob Nichols evaluated this report, testifying that when the report was
written, only six state commissions considered imputed debt at all. And half of
these state commissions considered imputed debt on power purchase agreements in
general rate cases where they could also evaluate the utilities’ total cost of capital.
(9 TR 2806.) Consistent with this accepted practice, Mr. Nichols recommended that
the Commission consider imputed debt “in the context of setting a reasonable cost of
capital in a general rate case.” (9 TR 2806.)
The Colorado Public Utilities Commission explained why it makes sense to
evaluate imputed debt in rate cases. By doing so, it said, “all the moving parts of
the issue will be examined at the same time, including the impact on the Company’s
financial health as well as the impact on ratepayers.” (Exhibit S-1, p 3, citation
11
omitted.) The Colorado Commission rejected a utility’s request for an imputed-debt
adder on PPA bid evaluations. It reasoned that in a resource-acquisition docket “all
aspects of Public Service’s capital costs as they relate to imputed debt are not
examined as they would in a rate case.” (Id.) Other states have rejected similar
attempts to consider imputed debt in PPA bid evaluations or in utility IRPs. (See
Exhibit S-1, pp 3-6.) Further research into how states have approached the
imputed-debt issue since the Brattle Group report confirms the report’s findings.
(See Staff’s Revised Initial Br, pp 68–69.)
Unlike states that consider imputed debt together with other cost-of-capital
issues in rate cases, Consumers views the financial incentive in isolation. It
proposes to evaluate a PPA’s imputed debt when it enters the contract, without
considering the overall return that the Company is earning and whether it is high
enough to offset the PPA’s imputed debt. (See 7 TR 740.) This led the Company to
propose an exorbitant incentive. On a 10-year PPA, the Company would earn a
13.8% incentive, while on a 20-year PPA, the Company would earn a 21.53%
incentive. (7 TR 731; 9 TR 2716.) This is far above the 5.89% total weighted
average cost of capital the Commission approved in Consumers’ last contested rate
case. (7 TR 730; 9 TR 2716.) In response to discovery, the Company estimated its
incentive’s unit cost ($/MWh), which Staff used to calculate the revenue that the
Company would have received if its existing PPAs had earned an incentive: the
total revenue would have been somewhere between $48 million to $183 million per
year. (9 TR 2804-2805.)
12
By calculating a PPA’s imputed debt in a vacuum, without accounting for the
overall cost of capital, Consumers would earn a return that is higher than it needs
to be to protect its credit rating. The Company argues that it must recover its
PPAs’ imputed debt to avoid adversely affecting its credit rating.1 But the
Company’s credit rating is solid: as of “November 13, 2017, S&P [Standard & Poor’s
Financial Services, LLC] credit rating for Consumers was BBB+/ Stable/A-2.” (9 TR
2805; Exhibit S-15.1.) And the Company is already earning returns above its
authorized return on equity: “[I]n 2017, on a financial basis, the company earned
10.15% and on a ratemaking basis, earned 10.26%, with an authorized ROE of
10.1%.” (9 TR 2805; Exhibit S-15.5.) Further, the Company’s authorized return is
36 basis points above the “total US mean ROE for 2017 of 9.74%,” which has about
a “$22 million revenue requirement impact.” (9 TR 2805-2806; Exhibit S-15.6.)
This should certainly be considered when deciding how much a PPA’s imputed debt
would negatively affect the Company’s credit rating.
The imputed debt associated with PPAs “is only a very small component of
the overall outlook of a Company’s financial health.” (9 TR 2714.) Staff witness
1 Company witness Srikanth Maddipati testified that “[w]hile each of the three major credit rating agencies (S&P, Moody’s, and Fitch) have different methodologies, each agency considers the impact of imputed debt created by PPAs.” (7 TR 723.) Company witness Michael Torrey further said, “[A] competitive bid methodology presents significant risks to the Company’s ability to attract capital investment for needed infrastructure investments and provide sustainable returns to investors unless there is an incentive for the Company to enter into PPAs. Otherwise, the Company’s credit ratings could become stressed and the Company would have a bias towards constructing its own projects to own, or entering into ‘build-transfer’ agreements . . . .” (8 TR 1474, emphasis added.)
13
Jesse Harlow observed that while a PPA may come with some level imputed debt, it
is not always necessary to offset that imputed debt to protect a utility’s credit
rating. Other aspects of the utility’s business “simultaneously affect [its] future
capital structure and ultimately the cost of capital.” (Id.) For example, “Company
decisions such as the termination of current PPAs, financing Company-owned
facilities, and regulatory decisions, to name a few, all play a role in the capital
structure calculation.” (Id.) This is why it makes sense to consider imputed debt
together with the Company’s capital structure and cost of capital in a rate case.
In this context, Consumers’ proposed incentive is too high. As Mr. Harlow
testified, “The Company’s calculation inappropriately combines both a PPA FCM
and an imputed debt offset mechanism into one calculation. This results in a return
that is much higher than the Company’s weighted average cost of capital (WACC)
which does not align with PA 341 of 2016 (MCL 460.6t)(15).” The Company
responds that Staff reached this conclusion by applying the Company’s proposed
incentive to the wrong base. According to the Company, “Cost of capital rates are
applied to capital balances (i.e., debt and equity), not expense balances.”
(Consumers’ Exceptions, p 82, quoting 7 TR 752-753.) This is essentially a balance-
sheet problem that Staff has already resolved. (See Staff’s Reply Br, pp 3–5.)
The Company also says that if “the law intended to cap any FCM as the PPA
expense times the Company’s WACC it could have said so explicitly.” (Consumers’
Exceptions, p 82.) This is semantics. It is just as easy to say that if the Legislature
intended to cap the incentive at the PPA’s imputed debt, “it could have said so
14
explicitly.” Section 6t(15) is clear on its face and in context. See Griffith v State
Farm Mutual Auto Ins Co, 472 Mich 521, 533 (2005) (“[T]he meaning of statutory
language, plain or not, depends on context.”). Section 6t(15) allows the Commission
to authorize a PPA incentive but capped the incentive at “the utility’s weighted
average cost of capital.” MCL 460.6t(15). A utility’s Commission-approved
weighted average cost of capital is a number that can be found in most rate case
orders.
The Company should follow a fair and transparent competitive-bidding process until the Commission approves uniform rules and processes.
In response to the ALJ’s concerns that Consumers’ competitive-bidding
proposal “lacks sufficient safeguards to ensure ratepayer interests are protected,”
(PFD, p 202), the Company committed to following procedures designed to ensure a
fair and transparent process. These procedures include using an independent
evaluator during competitive solicitations, following RFP parameters the
Commission approved in Case No. U-15800, timely issuing an RFP through public
notice, and including the terms of the contract in the RFP. (Consumers’ Exceptions,
pp 37–38.) Requiring the Company to follow through with these commitments will
provide enough safeguards for now to ensure that the process is fair and open. But
Staff encourages the Commission to implement uniform standards on best practices
for competitive bidding and RFPs that all utilities can use.
Specifically, Staff recommends approving Consumers’ proposed RFP and
competitive-bidding processes, while preventing unnecessary delay to utility RFPs
15
while uniform rules and regulations for these processes are under development.
Staff disagrees with the Michigan Energy Innovation Business Council (MIEBC)
and the Institute for Energy Innovation (IEI) that the Commission should approve
uniform rules and regulations for RFPs and competitive bidding before Consumers
implements competitive bidding as part of its IRP. Rather, Staff recommends that
the Commission give notice and seek comments from stakeholders and the public on
best practices for RFPs and competitive bidding in a separate docket. This docket
should move forward expeditiously, but it should not delay utility RFPs issued in
conjunction with an IRP proceeding or in accordance with a Commission-approved
IRP.
Below, the MIEBC and IEI pointed out that the Commission “expects
competitive bidding to be of increasing importance for the selection of resources and
the approved amounts under the pre-approval provisions of CONs and IRPs.”
(MIEBC-IEI’s Initial Br, p 4, quoting In re DTE’s Application for a Certificate of
Necessity, MPSC Case No. U-18419, 4/27/2018 Order, p 106.) Although the
Commission directed “Staff to research approaches and best practices for RFP and
competitive bidding in other jurisdictions,” it did not require Staff to complete its
study before utilities issue RFPs. (Id.) MIEBC and IEI argued that Consumers’
proposed use of RFPs and competitive bidding “should not be implemented until
such a study by Staff is completed” and uniform rules or standards are
implemented. (MIEBC-IEI’s Initial Br, p 6.) Staff disagrees with MIEBC and IEI,
but only concerning the timing of the implementation of uniform rules or standards
16
on best practices. Staff agrees with MIEBC and IEI’s substantive recommendations
related to RFPs and competitive bidding.
MIEBC and IEI witness Dr. Laura Sherman testified that adoption of
uniform rules or best practices for RFPs and competitive bidding “should be done
with stakeholder input and according to best practices, including those established
in other states.” (9 TR 2839.) Staff agrees and recommends that the Commission
seek comments from stakeholders and the public on best practices for RFPs and
competitive bidding in a separate docket on a separate timeline. The separate
timeline is necessary to avoid interfering with the implementation of, not only
Consumers’ IRP, but the development and implementation of all other Michigan
utilities’ IRPs scheduled to be filed in the first half of 2019.
Act 341, Section 6t(6), requires utilities to conduct RFPs to “provide any new
supply-side generation capacity resources” and to “use the resulting proposals to
inform its integrated resource plan filed under this section and include all of the
submitted proposals as attachments to its integrated resource plan filing.” MCL
460.6t(6). The statute contemplates completed RFPs with proposals attached to the
utility-filed IRP applications, which are presently under development based on the
IRP filing requirements approved in Case No. U-18461. Changing the rules on
Michigan utilities by implementing new RFP regulations and competitive bidding
processes while their applications are under development or being litigated, as in
Consumers’ case, is not advisable.
17
Staff recommends that the Commission consider all of MIEBC and IEI’s
specific proposals relating to best practices for RFPs and competitive bidding in a
separate docket addressing uniform rules and processes for all utilities. Staff
recommends that the Commission open a docket after the present IRP case is
concluded, directing Staff to file its proposed best practices for RFPs and
competitive bidding, while allowing for comments, reply comments, and a
Commission order before the end of 2019. In the interim, the Company’s proposed
RFP and competitive-bidding processes should be approved, as reflected in the
Company’s Exceptions and modified to include any of MIEBC and IEI’s
recommendations the Commission deems proper at this time.
The ALJ did not find annual solicitations to be unreasonable or imprudent.
As Consumers reads the PFD, the ALJ opposed Staff’s proposal for annual
solicitations. (Consumers’ Exceptions, pp 42–44.) This is not how Staff reads the
PFD. The ALJ undoubtedly rejected the competitive-bidding process, and if
adopted, this would necessarily preclude annual solicitations. But the ALJ did not
single out annual solicitations for criticism. Rather, the ALJ rejected the larger
competitive-bidding framework because it allegedly lacks sufficient safeguards and
gives the utility and its affiliates a potential advantage over its competitors. (PFD,
p 202.) Staff addressed these issues above, but it writes separately here to stress
that the ALJ did not object to Staff’s annual-solicitation proposal and to once again
tout Staff’s proposal.
18
Annual solicitations ensure that Consumers uses the most up-to-date costs
for IRP modeling and avoided costs. (9 TR 2721.) Annual solicitations also allow
developers that would otherwise ask for PURPA contracts to bid in larger projects,
allowing for greater economies of scale and interconnection at the transmission
level. Interconnecting to the transmission network reduces the complexity and
costs of interconnection when compared to large PURPA contracts interconnecting
at the distribution level. (9 TR 2722.) The Company agrees. (8 TR 1281.)
Costs eligible for preapproval do not include operations and maintenance costs, the unrecovered book value of generating assets, or decommissioning costs.
Act 341, Section 6t(11) directs the Commission to “specify the costs approved
for the construction of or significant investment in” certain facilities or power
purchase agreements. MCL 460.6t(11). The statute goes on to list several
investments that qualify for preapproval, all of which are capital projects that the
utility builds, purchases, or purchases power from. The investments listed are “an
electric generation facility, the purchase of an existing electric generation facility,
the purchase of power under the terms of the power purchase agreement, or other
investments or resources used to meet energy and capacity needs that are included
in the approved integrated resource plan.” Id. Once approved in the IRP, the “costs
for [these] specifically identified investments” are then essentially preapproved—
i.e., “considered reasonable and prudent for cost recovery purposes”—if the utility
begins making the investment within three years of the plan’s approval. MCL
460.6t(11) and (17).
19
Since only “specifically identified investments” are preapproved for cost
recovery, this phrase is important. And it can only be understood in context.
Griffith v State Farm Mutual Auto Ins Co, 472 Mich 521, 533 (2005) (“[T]he
meaning of statutory language, plain or not, depends on context.”) The phrase
“specifically identified investments” refers back to the “construction of or significant
investment in” certain facilities identified in the prior sentence. MCL 460.6t(11).
These investments are all capital investments, with the caveat described below. Id.
Consumers’ O&M costs, the Karn Units’ unrecovered book value, and those units’
decommissioning costs (all costs included in the Company’s plan) are not included in
the list of investments. The law does not guarantee these costs will be considered
reasonable and prudent for cost recovery purposes.
While a PPA may include operations and maintenance costs, and these PPA
costs may be passed on to ratepayers through the PSCR clause, (Consumers’
Exceptions, p 98), it is still a capital cost for the third party building it. More
importantly, however, a contractual PPA “investment” is fundamentally different
from an O&M “expense.” Section 6t applies only to “costs approved for the
construction of or significant investment in” certain facilities, power purchase
agreements, and other resources used to meet energy and capacity needs. MCL
460.6t(11) (emphasis added). Nowhere in Section 6t(11) or (12) does it suggest that
IRP cost preapproval extends to common O&M expenses. As Staff witness Paul
Proudfoot succinctly said, “While section 6t(11) specifically mentions the approval of
costs for investments, it does not mention the approval of costs that would be
20
classified as expenses. O&M expenses would traditionally be classified as
expenses.” (9 TR 2556.)
That a PPA is a contractual investment that is different than a common
expense is also evident in Section 6s, the Certificate of Necessity (CON) section,
which should be read together with Section 6t. “Statutes that address the same
subject or share a common purpose are in pari materia and must be read together
as a whole.” People v Harper, 479 Mich 599, 621 (2007). A statute that shares a
common purpose with another statute “should be read in connection with it, as
together constituting one law.” Detroit v Mich Bell Tel Co, 374 Mich 543, 558
(1965), overruled on other grounds. Sections 6s and 6t plainly address the same
subject, even requiring the Commission to consolidate a CON case with an IRP case
if the utility is seeking preapproval for a generating unit or units totaling 225 MW
or more.
Section 6s, like Section 6t(11), empowers the Commission to preapprove costs
for certain projects and purchases, except the projects and purchases approved
through Section 6s CONs are larger than those approved in Section 6t IRPs. It
allows electric utilities to seek a CON if they are planning to “construct an electric
generation facility, make a significant investment in an existing electric generation
facility, purchase an existing electric generation facility, or enter into a power
purchase agreement for the purchase of electric capacity for a period of 6 years or
longer,” but the “construction, investment, or purchase” must be for $100 million or
more. Id. The italicized language mirrors the language in Section 6t(11) quoted
21
above. See MCL 460.6t(11). And Section 6s makes clear that the investment
cannot be for common expenses, although a group of investments may be
aggregated if they are planned “for a singular purpose such as increasing the
capacity of an existing electric generation plant.” MCL 460.6s(1) (emphasis added).
O&M expenses are common expenses that, as its name implies, generally
contribute to operating and maintaining a facility, not upgrading a facility. O&M
expenses are not intended for a singular purpose like increasing the capacity of an
existing facility. Although the “singular purpose” language cannot be found in
Section 6t, Section 6s must be read together with Section 6t, and in any case, there
was no reason to include the “singular purpose” language in Section 6t because it
does not allow for aggregation like Section 6s. But this does not mean Section 6s
and Section 6t do not share the same purpose: preapproval of projects that increase
a utility’s energy and capacity resources. Constructing a facility, purchasing a
facility, or purchasing power from a facility, under Section 6t, all advance this
“singular purpose,” which is why there was no need to include the “singular
purpose” language in this section. It was understood by the nature of the projects
themselves. Because O&M expenses do not meet this “singular purpose,” they are
not eligible for preapproval.
In addition to not covering O&M expenses, Section 6t also does not cover the
Karn Units’ unrecovered book value and their decommissioning costs. These costs
do not qualify for preapproval. Not only are they not used to construct or make a
significant investment in an electric generating facility or to purchase power, these
22
costs do not even go toward an investment or resource used to meet energy and
capacity needs. Consumers’ IRP is its plan going forward to meet “the utility’s load
obligations.” MCL 460.6t(3). The unrecovered book value of generating units that
have reached the end of their useful lives are sunk costs that can no longer be used
to meet these obligations. The Legislature talked about “new facilities” and
facilities “used to meet energy and capacity needs,” MCL 460.6t(11),(12), not old
plants that will soon be retired. They are clearly not the kind of costs eligible for
preapproval. And while Section 6t references existing facilities, (see Consumers’
Exceptions, pp 94–95), if these facilities are planned for retirement and will not to
be available meet “the utility’s load obligations” going forward, they are beyond the
scope of a forward-looking plan.2
Consumers has also argued that the catchall in Act 341 expands the list of
investments that qualify for preapproval. (Consumers’ Exceptions, p 99.) The Act
allows the Commission to preapprove, in addition to the capital investments listed,
“other investments or resources used to meet energy and capacity needs that are
included in the approved integrated resource plan.” MCL 460.6t(11). The
unrecovered book balance of a retired plant and its decommissioning costs do not
qualify under this catchall, as just described, but a stronger argument can be made
2 The Commission’s Integrated Resource Plan Filing Requirements also do not mention unrecovered book value or decommissioning costs in the section on cost approvals.
23
that the catchall applies to O&M expenses. The problem is that O&M expenses are
not in the same class as the investments described in the statute.
Under the doctrine of ejusdem generis, “when a general word or phrase
follows a list of specifics, the general word or phrase will be interpreted to include
only items of the same class as those listed.” Home-Owners Ins Co v Andriacchi,
320 Mich App 52, 63 (2017). O&M expenses are not in the same class as the listed
capital investments. Id. As Mr. Proudfoot testified, Section 6t(11) specifically says
that certain “investments” qualify for cost preapproval, but “O&M expenses would
traditionally be classified as expenses,” not investments. (9 TR 2556.) The catchall
in Section 6t(11) does not cover O&M expenses.
Finally, Consumers argued that “even if the provisions of MCL 460.6t did not
include the pre-approval of O&M costs, which the Company does not agree, the
Commission would still have the authority to pre-approve the recovery of O&M
costs in this proceeding.” (Consumers’ Exceptions, p 99.) Staff does not dispute the
Commission’s broad ratemaking authority, but if the Commission has discretion to
preapprove these costs under its broad ratemaking authority, it also has discretion
not to preapprove these costs consistent with Section 6t’s plain meaning. Staff
recommends that the Commission not preapprove O&M costs in this proceeding but
that it consider O&M costs in rate cases as it has traditionally done.
The upshot is that even if the Commission approves a plan with O&M costs,
sunk costs, and decommissioning costs, Consumers is not guaranteed to recover
24
those costs. The Commission can make this abundantly clear by recommending
that the Company remove these costs from its plan, MCL 460.6t(7), or simply not
identifying these costs among the costs being approved.3 See MCL 460.6t(11).
Consumers should improve the granularity of its load forecast.
Staff recommended that Consumers be directed to improve the granularity of
its load forecast, and the ALJ agreed, finding that Staff witness Olumide Makinde
provided a reasonable basis for the recommendation. (PFD, p 295.) The Company
took exception, stating that it does not have enough hourly data from smart meters
to meet this request. (Consumers’ Exceptions, p 101.) Staff understands that the
Company does not have 15 years of smart-meter data, but the Company should
continue working with Staff towards improving the granularity in its forecasts. As
such, Staff urges Consumers to continue improving its load forecast and asks the
Commission to direct the Company to work with Staff on these improvements.
Response to the Midland Cogeneration Venture (MCV) and the Association of Businesses Advocating Tariff Equity (ABATE)
MCV and ABATE continue to oppose Consumers’ proposal to retire Karn
Units 1 and 2 early in 2023. The Attorney General, who once opposed early
retirement, did not file Exceptions on this issue. MCV argues that the Company’s
retirement analysis was flawed because it did not use the Annual Energy Outlook
3 Section 6t(11) requires the Commission to “specify the costs approved,” but it does not say the costs approved have to be equal to the costs included in the plan.
25
(AEO) gas forecast as required in the Michigan Integrated Resource Planning
Parameters (MIRPP). (MCV’s Exceptions, p 5.) ABATE summarized the parties’
arguments against early retirement, saying that “the Company failed to establish
that early retirement is a reasonable and prudent option, as well as raising
contentions that the Company’s analysis overestimates the benefits of early
retirement for the units.” (ABATE’s Exceptions, p 8.)
The ALJ did not rely as heavily on the Company’s retirement analysis of the
Karn Units as she did Staff’s analysis, finding that Staff’s analysis was sufficient to
justify early retirement. (PFD, p 179.) The ALJ described Staff witness Zachary
Heidemann’s testimony that “all model runs show savings when Consumers
Energy’s gas price is used with a capacity replacement cost of 75% of CONE.” (Id.)
Mr. Heidemann said, and the ALJ apparently agreed, that the decision to retire the
units early is not a high-risk decision. And while the Company might save more if
it retired the units in 2021, even if only a little, “the Company must balance the
needs of the workforce and the communities that serve Karn Units 1&2 when those
units are retired.” (Id., quoting 9 TR 2685–2686.) And Mr. Heidemann said that
“[t]he 2023 retirement date allows the Company additional time to transition when
the units retire.” (9 TR 2686.)
MCV argues the Company’s retirement analysis was flawed because it did
not use the AEO gas forecast as required in the MIRPP. Instead, the Company
used its own Business as Usual (BAUCE) forecast. (MCV’s Exceptions, p 5.) Staff
does not agree that the Commission has required Consumers to use the AEO gas
26
forecast. The Medium 4 retirement analysis included in this IRP was to be “a
standalone analysis of various retirement scenarios for D.E. Karn Units 1 and 2 and
J. H. Campbell Units 1 and 2.” In re Consumers Energy Co’s 2017 Rate Case, MPSC
Case No. U-18322, 3/29/2018 Order, p 130. The Commission required the Company
to address the following topics in its analysis:
(1) capacity replacement costs; (2) impact of recovery of undepreciated book value; (3) customer rate impact analysis; (4) non-economic variables such as portfolio balance, employment,
and community impact; (5) effect on contractual fuel obligations; (6) near-term revenue requirements; (7) conditions of existing equipment; and (8) execution risk. [Id. at 23.]
The Commission did not specify what gas price to use in this analysis. The gas
price forecast used by the Company is reasonable, (9 TR 2628), and it complies with
the March 29, 2018 Order in Case No. U-18322.
The MIRPP adds other requirements for retirement analyses beyond the
standalone requirements for Consumers listed above. See In re Section 6t(1) of 2016
PA 341, MPSC Case No. U-18418, 11/21/2017 Order, Exhibit A. But these
requirements are generally flexible, allowing the Company to use age assumptions,
public announcements, or economics within the model. The emerging technology
scenario in the MIRPP also specifies that “Company-owned resource retirements
may be defined by the utility, however, meaningful analysis of whether coal units
should retire ahead of business as usual dates should be performed.” In re Section
27
6t(1) of 2016 PA 341, MPSC Case No. U-18418, 11/21/2017 Order, Exhibit A, p 18.
An AEO natural gas price forecast is not required for this “meaningful analysis.”
Consumers has met the criteria for retirement analyses set forth in Case No.
U-18322 and the MIRPP. MCV’s argument that the Company used the wrong gas
price is just a small piece of the overall retirement analysis. Company witness
Thomas Clark discussed several non-modeling considerations that favor retirement,
(7 TR 887–900), and Staff agrees that these should be considered and that they
support early retirement.
Response to the Solar Energy Industries Association (SEIA)
SEIA reiterates its argument that Consumers has “a capacity need that
obligates it to make full capacity payments to QFs beyond the 150 MW previously
required by the Commission.” (SEIA’s Exceptions, p 8.) Specifically, SEIA argues
that “the Commission should find that Consumers has a capacity need of no less
than 80 ZRCs [zonal resource credits].” (Id. at 8–9.) In its plan, as filed, Consumers
estimated that it had a surplus of 183 ZRCs in 2023. (6 TR 256, Figure 5.)
Removing the 157 ZRCs from the surplus for the Filer City PPA that FERC refused
to recertify as a qualifying facility, (6 TR 274), 50 ZRCs for solar in the Company’s
Renewable Energy Plan that the Commission deferred to this case, (6 TR 253), and
56 ZRCs for the CVR that the ALJ recommended excluding from the IRP leaves the
Company with the 80 ZRC deficit SEIA referenced.
28
Consumers witness Richard Blumenstock confirmed that the Company is no
longer moving forward with the Filer City PPA expansion, (6 TR 276), so Staff does
not dispute that this capacity has become available for the Company to fill through
other resources. As for the 50 ZRCs of solar in the Company’s Renewable Energy
Plan, the Commission “reserve[ed] its determination regarding the solar projects
until the final order in the IRP.” In re Consumers Energy Co’s 2017 Application to
Amend its Renewable Energy Plan, MPSC Case No. U-18231, 2/7/19 Order, p 28.
Doing so, it said, “will allow the Commission to evaluate the proposed solar
generation in a more complete context of the company’s long-term energy and
capacity needs, as well as alternatives such as third-party ownership that may be a
more cost-effective means of RPS compliance for this resource.” Id. If the
Commission does not approve the 50 ZRCs of solar in this case, Staff further agrees
that these ZRCs are available for the Company to fill through other resources.
Staff’s position on Consumers’ proposed CVR program has not changed. Staff
supports approval of the CVR program in this IRP along with preapproval of
$8,924,600 in capital expenditures for this program. (9 TR 2555–2556.) If, however,
the Commission were to exclude CVR from the Company’s plan, it would open up
additional ZRCs. But regardless of the amount of capacity that is removed from the
Company’s plan, the Company should be given an opportunity to respond to any
revisions to its preferred course of action before determining its capacity need.
Once its capacity need is finalized, the Company should use its proposed
competitive-bidding process to slowly secure additional supply- and demand-side
29
resources in small increments that will allow the Company to adapt as
circumstances change.
Conclusion
Staff encourages the Commission to approve Consumers’ IRP with the
changes that Staff has recommended throughout the course of this proceeding.
