the Notes to be redeemed or (ii) the sum of the present values of the remaining
scheduled payments of principal and interest thereon discounted to the
redemption date on a semi-annual basis (assuming a 360-day year consisting of

"Treasury Yield" means , with respect to any redemption date, the rate per
annum equal to the semi-annual equivalent yield to maturity of the Comparable
Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as
a percentage of its principal amount) equal to the Comparable Treasury Price for
such redemption date.
"Comparable Treasury Issue" means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to
the remaining term of the Notes that would be utilized, at the time of selection
and in accordance with customary financial practice, in pricing new issues of
corporate debt securities of comparable maturity to the remaining term of the
Notes.
"Comparable Treasury Price" means, with respect to any redemption date, (i)
the average of the bid and asked prices for the Comparable Treasury Issue
(expressed in each case as a percentage of its principal amount ) on the third
business day preceding such redemption date, as set forth in the daily
statistical release (or any successor release) published by the Federal Reserve
Bank of New York and designated "Composite 3:30 Quotations for U.S. Government
Securities" or (ii) if such release (or any successor release) is not published

Reference Treasury Dealer Quotations for such redemption date, after excluding

U.S. Government securities dealer in New York City (a "Primary Treasury Dealer")

Salomon or any of its designees shall cease to be a Primary Treasury Dealer, we
will appoint another Primary Treasury Dealer as a substitute for such entity and
(ii) any other Primary Treasury Dealer selected by us..

A notice of redemption may provide that it is subject to certain
conditions, which will be specified in the notice. If those conditions are not
met, the redemption notice will be of no effect and we would not be obligated to

by first-class mail not less than 30 days prior to the redemption date.
The Notes do not provide for any sinking fund.
We may purchase the Notes in the open market, by tender or other methods.
We may hold these purchased Notes, resell them or give them to the Trustee for

under the Securities Exchange Act of 1934 and other securities laws and
regulations in connection with any such purchase. The Notes may be defeased in
the manner provided in the Indenture.
BOOK-ENTRY ISSUANCE -- THE DEPOSITORY TRUST COMPANY
DTC will act as securities depositary for the Notes. The Notes will
initially be issued only as fully registered securities registered in the name
of Cede & Co. (DTC's partnership nominee). One or more fully registered global
certificates representing the total aggregate principal amount of the Notes will
be issued and will be deposited with the Trustee as custodian for DTC.
The laws of some jurisdictions require that certain purchasers of
securities take physical delivery of securities in definitive form. Such laws
may impair the ability to transfer beneficial interests in the Notes as
represented by a global certificate.
DTC management is aware that some computer applications, systems and the
like for processing data that are dependent upon calendar dates may encounter
"Year 2000" problems. DTC's Internet site (http://www.dtc.org) contains
detailed information regarding DTC's progress and plans to support industry
preparations for the impending date change at the end of the decade. DTC has
informed its Participants and other members of the financial community that it
is implementing a program so that its systems, as the same relate to the timely
payment of distributions (including principal and income payments) to
securityholders, book-entry deliveries, and settlement of trades within DTC,
continue to function. This program includes a technical assessment and a
remediation plan, each of which is complete according to DTC. DTC's plan also
includes a testing phase, which is expected to be completed within appropriate
time frames.
DTC's ability to perform its services is also dependent upon other parties,
including but not limited to issuers and their agents, as well as third party
vendors from whom DTC licenses software and hardware, and third party vendors on
whom DTC relies for information or the provision of services, including
telecommunications and electrical utility service providers, among others. DTC
has indicated that it is contacting third party vendors from whom DTC acquires
services to: (i) impress upon them the importance of such services being Year
2000 complaint; and (ii) determine the extent of their efforts for Year 2000
remediation of their services. In addition, DTC is in the process of developing
such contingency plans as it deems appropriate.
SPS, the Trustee and any underwriter cannot and do not give any assurances
that DTC, DTC Participants or others will distribute payments of debt service on
Notes made to DTC or its nominee as the registered owner, or any redemption or
other notices, to the book-entry interest owners, or that they will do so on a
timely basis, or that DTC will serve and act in the manner described in this
Prospectus Supplement and accompanying Prospectus.
For additional information relating to DTC and the book-entry issuance
system, see "Book-Entry Only System" in the accompanying Prospectus.

UNDERWRITING
Subject to the terms and conditions set forth in the Underwriting Agreement
that relates to the Notes, SPS has agreed to sell to each of the Underwriters
named below, and each of the Underwriters has severally agreed to purchase, the
respective principal amounts of the Notes set forth opposite its name below:
<TABLE>
<CAPTION>
Principal Amount
----------------
<S> <C>
Salomon Smith Barney Inc................. $ 60,000,000
Chase Securities Inc..................... $ 20,000,000
NationsBanc Montgomery Securities LLC.... $ 20,000,000
------------
Total............................... $100,000,000
============
</TABLE>
The Underwriting Agreement provides that the obligations of the several
Underwriters to purchase the Notes offered by this Prospectus Supplement are
subject to the approval of certain legal matters by their counsel and certain
other conditions. If any of the Notes are purchased by the Underwriters pursuant
to the Underwriting Agreement, then all of the Notes must be purchased.
The Underwriters have advised the Company that they propose initially to
offer some of the Notes to the public at the public offering price set forth on
the cover page of this Prospectus Supplement, and some of the Notes to certain
dealers at this public offering price less a concession not in excess of 0.40%
of the principal amount of the Notes. The Underwriters may allow, and such
dealers may reallow, a concession not in excess of 0.25% of the principal amount
of the Notes on sales to certain other dealers. After the initial offering of
the Notes to the public, the Underwriters may change the offering price and
other selling terms.
The following table shows the underwriting discounts and commission to be
paid to the Underwriters by SPS in connection with this offering (expressed as a
percentage of the principal amount of the Notes)
Paid by SPS
-----------
Per Note.............................. 0.650%
Prior to this offering, there has been no public market for the Notes. The
Underwriters have informed us that they may make a market in the Notes from time
to time. The Underwriters are not obligated to do this, and they may discontinue
this market making at any time without notice. Therefore, no assurance can be
given concerning the liquidity of the trading market for the Notes or that an
active market will develop. We do not intend to apply for the Notes to be listed
on any national securities exchange or national securities quotation system.
In connection with the offering, Salomon Smith Barney Inc., on behalf of
the Underwriters, may overallot, or engage in syndicate covering transactions,
stabilizing transactions and penalty bids. Over-allotment involves syndicate
sales of Notes in excess of the principal amount of the Notes to be purchased by
the Underwriters in the offering, which creates a syndicate short position.
Syndicate covering transactions involve purchases of the Notes in the open
market after the distribution has been completed in order to cover syndicate
short positions. Stabilizing transactions consist of certain bids or purchases
of Notes made for the purpose of preventing or retarding a decline in the market
price of the Notes while the offering is in progress. Penalty bids permit the
Underwriters to reclaim a selling concession from a syndicate member when
Salomon Smith Barney Inc., in covering syndicate short positions or making
stabilizing purchases, repurchases Notes originally sold by that syndicate
member. These activities may cause the price of the Notes to be higher than the
price that otherwise would exist in the open market in the absence of such
transaction. These transactions may be effected in the over-the-counter market
or otherwise and, if commenced, may be discontinued at any time.
S-9
<PAGE>
SPS estimates that its total expenses of this offering will be $350,000.
We have agreed to indemnify the Underwriters against certain liabilities,
including liabilities under the Securities Act of 1933. Alternatively, we may
contribute to payments that the Underwriters may be required to make as a result
of these liabilities.
In the ordinary course of their respective businesses, certain of the
Underwriters and their affiliates have engaged, and may in the future engage, in
investment banking or commercial banking transactions with us or our affiliates.
The Chase Manhattan Bank, the Trustee for the Notes, is an affiliate of Chase
Securities Inc., one of the Underwriters.
LEGAL OPINIONS
Certain legal matters in connection with the Notes are being passed upon
for us by Hinkle, Cox, Eaton, Coffield & Hensley, L.L.P., Amarillo, Texas, and
LeBoeuf, Lamb, Greene & MacRae, L.L.P. (a limited liability partnership
including professional corporations) New York, New York. Certain legal matters
in connection with the offering or offerings of the Notes will be passed upon
for the Underwriters by Cahill Gordon & Reindel (a partnership including a
professional corporation), New York, New York. LeBoeuf, Lamb, Greene & MacRae,
L.L.P. is not passing upon our incorporation. LeBoeuf, Lamb, Greene & MacRae,
L.L.P. and Cahill Gordon & Reindel are relying upon the opinions of Hinkle, Cox,
Eaton & Coffield & Hensley, L.L.P. as to matters of New Mexico and Texas law;
Rainey, Ross, Rice & Binns, Oklahoma City, Oklahoma, as to matters of Oklahoma

EXPERTS
The information contained in this section supplements the information
contained in the accompanying Prospectus under the caption "Experts". You should
read both sections for complete information.
The balance sheets and statements of capitalization of SPS as of December
31, 1998 and 1997, and the related statements of income, shareholder's equity
and cash flows for each of the two years in the period ended December 31, 1998,
included in the SPS Form 8-K dated February 23, 1999, and the consolidated
balance sheet and statement of capitalization of SPS as of December 31, 1997,
and the related consolidated statements of income, shareholder's equity and cash
flows for the year then ended and the related financial statement schedule
included in the New Century Energies, Inc.'s combined Annual Report on Form 10-K
for the year ended December 31, 1997, which statements and schedule are
incorporated by reference in this Prospectus Supplement and the related
Prospectus, have been audited by Arthur Andersen LLP, independent public
accountants, as indicated in their reports with respect thereto, and are
incorporated by reference herein in reliance upon the authority of said firm as
experts in giving said reports.
With respect to the unaudited condensed interim financial information of
SPS for the quarters ended March 31, 1998 and 1997, June 30, 1998 and 1997 and
September 30, 1998 and 1997, included in the New Century Energies, Inc.'s
combined Form 10-Q's, which are incorporated by reference herein, Arthur
Andersen LLP has applied limited procedures in accordance with professional
standards for the reviews of such information. However, their separate reports
thereon state that they did not audit and they do not express an opinion on that
interim financial information. Accordingly, the degree of reliance on their
reports on that information should be restricted in light of the limited nature
of the review procedures applied. In addition, the accountants are not subject
to the liability provisions of Section 11 of the Securities Act of 1933 for
their reports on the unaudited condensed interim financial information because
those reports are not a "report" or a "part" of the Registration Statement,
prepared or certified by the accountants within the meaning of Sections 7 and 11
of the Act.
