Dear Mr. Hanson:

	We have reviewed your filings and have the following
comments.
Please be aware that we have conducted only a limited review of
your
Form S-4.  Where indicated, we think you should revise your
documents
in response to these comments.  If you disagree, we will consider
your explanation as to why our comment is inapplicable or a
revision
is unnecessary.  Please be as detailed as necessary in your
explanation.  In some of our comments, we may ask you to provide
us
with information so we may better understand your disclosure.
After
reviewing this information, we may raise additional comments.

	We look forward to working with you in these respects.  We
welcome any questions you may have about our comments or any other
aspect of our review.  Feel free to call us at the telephone
numbers
listed at the end of this letter.






Form S-3

Use of Proceeds, page 15
1. We reissue comment 9 in our letter dated April 15, 2005.
Please
discuss the use of proceeds you will receive in connection with
the
exercise of warrants, for which the underlying shares are being
offered for sale.

Selling Stockholders, page 15
2. We reissue comment 10 in our letter dated April 15, 2005.
Please
include an entry in the table for the additional shares you are
registering for issuance to future selling shareholders and
include a
footnote clarifying why you are unable to currently name the
shareholders.
3. We reissue comment 14 in our letter dated April 15, 2005.  It
remains unclear whether you have listed all persons who have
voting
or investment power of the securities being offered for sale.  For
example, the disclosure in footnote (4) to the table refers to
five
individuals who "may be deemed to beneficially own the shares" but
these five individuals "disclaim beneficial ownership."  Please
clearly identify those natural persons who have beneficial
ownership
within the scope of Regulation 13D.

Exhibit 5.1, Legality Opinion
4. Please revise your legality opinion to clearly opine on the
corporate laws of the jurisdiction of incorporation of the
company.

Form 10-K for the fiscal year ended December 31, 2004

Management`s Discussion and Analysis, page 41
5. We note your response to comment 25 in our letter dated April
15,
2005.  Please revise to more clearly disclose the progress of your
new policies, procedures, and control activities and fully discuss
the material effect, if any, the deficiencies identified in your
controls and procedures have on your operations.

Consolidated Statements of Cash Flows, page F-7
6. Please refer to comment 26 in our letter dated April 15, 2005.
You state you will revise cash flows used in investing activities
in
future filings to reflect the purchase and sale of Auction Rate
Securities.  We assume you consider them to be available-for-sale
securities as defined by paragraph 12.b of SFAS 115.  If so,
please
explain your reasoning for available-for-sale classification.  In
doing so, tell us how these securities provided you cash for the
2004
quarters.   Further, it is not clear whether the amounts of these
securities fluctuated based on buying and selling or maturity and
repurchase.  If the latter, tell us whether these securities
matured
or you elected proceeds from re-auction.  To the extent you are
buying and selling or allowing your securities to be remarketed,
please explain your basis for the proposed classification as cash
flows from investing activities.  Further, we note your assertion
that an amendment to your March 31, 2005 Form 10-Q is unnecessary
as
the reclassification of Auction Rate Securities from cash and cash
equivalents to current investments will have no impact on total
current assets, total assets, working capital position, results of
operations, financial covenants, cash flows from operating or
financing activities, or equity.  However, this reclassification
materially impacts previously reported cash and current
investments.
To the extent quantitatively or qualitatively material, please
amend
your Form 10-Q to restate your balance sheet and statement of cash
flows to reflect the reclassification.
7. Please refer to comment 27 in our letter dated April 15, 2005.
We
understand that cash held by Blue Dot is not included in
NorthWestern`s cash and cash equivalents.  However, it remains
unclear why dividends received from a consolidated affiliate
should
be shown as a cash flow from investing activities as opposed to
some
other treatment that is consistent with elimination of inter-
company
transactions.  Please explain in detail why you believe it is
appropriate to include dividends from a consolidated affiliate as
cash flows from investing activities.
8. Please refer to comment 28 in our letter dated April 15, 2005.
Tell us in further detail the type of transactions that comprise
the
line item investing cash flows for discontinued operations for
each
year presented in your response.  Please note that proceeds from
the
sale or disposal of discontinued operations should be classified
as
an investing cash flow.  We note your reference to footnote 10 to
paragraph 26 of SFAS 95, which states, "Separate disclosure of
cash
flows pertaining to extraordinary items or discontinued operations
reflected in those categories is not required."  However, this
does
not preclude you from properly classifying the proceeds from the
sale
of discontinued operations in investing activities.  Rather, it
only
suggests that you are not required to separately identify those
proceeds as relating to the sale of discontinued operations.





9. Please refer to comment 28 in our letter dated April 15, 2005.
We
note in your response the components of the change in net assets
of
discontinued operations.  Please explain why the total represents
the
change in net assets of discontinued operations rather than cash
flows provided by (used in) discontinued operations.  Further,
please
explain why the sum of operating, investing, and financing cash
flows
of discontinued operations does not equal the increase (decrease)
in
cash held by discontinued operations.

Notes to Consolidated Financial Statements

Note (3) Emergence from Bankruptcy and Fresh Start Reporting, page
F-
12
10. Please refer to comment 32 in our letter dated April 15, 2005.
You disclose in the Form 10-K that reorganization value is $1.5
billion.  However, based on review of the table provided in your
response, it appears the court-approved enterprise value of $1.5
billion is not consistent with reorganization value as defined by
SOP
90-7, which states that reorganization value "is viewed as the
fair
value of the entity before considering liabilities and
approximates
the amount a willing buyer would pay for the assets of the entity
immediately after the restructuring."  We therefore expect
reorganization value to equal $2.5 billion, or the assets of the
reorganized balance sheet.  As $1.5 billion appears to represent a
court defined enterprise value rather than reorganization value,
please revise your disclosure regarding reorganization value to
reflect the accounting definition set forth in SOP 90-7.  In doing
so, you should disclose both reorganization value and enterprise
value, including how these values are calculated.  Please show us
your revised disclosure in your response.  Additionally, in
calculating enterprise value, please explain why you subtracted
cash
and cash equivalents from long-term debt plus equity.
11. Please refer to comment 33 in our letter dated April 15, 2005.
We understand you are allowed to recover original cost and an
allowed
rate of return on utility property, plant and equipment.  We also
believe that assets should be valued at their estimated fair
values
at the fresh-start date.  Furthermore, paragraph 58 of SOP 90-7
gives
credence to the notion that the reorganization value may be more
representative of entity value than a non-distressed sale.  As
such,
any excess reorganization value should represent the entity`s
ability
to generate economic profits.  We believe these profits should be
minimal based on the adversarial negation process of bankruptcy.
Based on your use of the rate of return to discount regulatory
assets, at least as related to property, plant and equipment,
additional excess reorganization value was created.  We do not
believe the regulatory rate of return represents the rate of
return
that was implicitly accepted by your allowed claimants.  Given
that
regulated property, plant and equipment, although a tangible
physical
asset, in substance reflects a monetary cash flow from ratepayers,
we
believe the monetary cash flow should be discounted at a rate
consistent with that used in determining reorganization value.
To
do otherwise would result in financial statements that are not
representatively faithful to the underlying economics.  You imply
that Rule 5-02.13 of Regulation S-X would not permit recording of
an
acquisition adjustment on plant.  Please explain.  Finally,
although
your valuation analysis considered approaches other than
discounted
cash flows, our experience is that net present valuation is the
prime
determinant of value in reorganization situations.  Therefore it
should be utilized in pushing the reorganization value down to the
assets and liabilities of the bankrupt entity.

Note (18) Regulatory Assets and Liabilities, page F-41
12. Please refer to comment 36 in our letter dated April 15, 2005.
The last paragraph of your response indicates that competitive
transition charges are recorded at the recoverable amount and that
no
effect has been given to the lack of a reasonable return.  We
concur
that SFAS 71 does not permit deferred costs to be discounted to
fair
value upon incurrence of a regulatory asset.  However, we do
believe
that discounting regulatory assets that do not earn a return to
fair
value when applying purchase or fresh-start accounting is
necessary.
Paragraphs 9 and 20 of SFAS 71 do not provide an exception to this
requirement.  Please tell us the estimated amount of adjustment
required to discount your regulatory assets not earning a return
to
fair value and make the appropriate adjustment.  If you believe
this
adjustment is not required, explain your position in detail.

Note (21) Guarantees, Commitments and Contingencies

Qualifying Facilities Liability, page 45
13. Please refer to comments 37 and 38 in our letter dated April
15,
2005.  Please explain in detail how you determined FIN 39 does not
apply to the qualifying facilities obligations.  Further, please
explain how paragraph 37(k) of SFAS 141 supports the set-off of
amounts recoverable from customers against the unfavorable
obligation
to the qualifying facilities.  Additionally, although your long
term
supply and purchase obligations may qualify for the normal
purchases
and sales exception, you are still required to record the fair
value
of those obligations when applying fresh-start accounting.
Further,
please note that we do not believe the implicit set-off of
regulatory
assets against fresh-start liabilities is consistent with GAAP.
See
SAB Topic 10:F, by close analogy, which states that "costs meeting
the criteria of paragraph 9 of SFAS 71 should be presented on the
balance sheet as an asset and should not be offset against the
liability."  It appears the costs incurred related to both your
qualifying facilities obligation and long-term supply and purchase
obligations should be recorded as a regulatory asset and should
not
be offset against the liability.  Please explain in detail why
your
current accounting treatment is accepted practice in fresh-start
or
purchase accounting.
