INDEPENDENT AUDITORS' REPORT
To the Administrative Committee
Southwestern Public Service Company
   Tax Benefit Plan and Trust:
We have audited the accompanying statement of net assets available for benefits 
of the Southwestern Public Service Company Tax Benefit Plan and Trust (the 
Plan) as of August 31, 1994, and the related statement of changes in net assets 
available for benefits for the year then ended.  These financial statements are 
the responsibility of the Plan's management.  Our responsibility is to express 
an opinion on these financial statements based on our audit.

We conducted our audit in accordance with generally accepted auditing 
standards.  Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free of 
material misstatement.  An audit includes examining, on a test basis, evidence 
supporting the amounts and disclosures in the financial statements.  An audit 
also includes assessing the accounting principles used and significant 
estimates made by management, as well as evaluating the overall financial 
statement presentation.  We believe that our audit provides a reasonable basis 
for our opinion.

In our opinion, such 1994 financial statements present fairly, in all material 
respects, the net assets available for benefits of the Plan as of August 31, 
1994, and the changes in net assets available for benefits for the year then 
ended in conformity with generally accepted accounting principles.
Our audit was conducted for the purpose of forming an opinion on the basic 
financial statements taken as a whole.  The accompanying supplemental 
schedules, Item 27a - Schedule of Assets Held for Investment Purposes as of 
August 31, 1994, and Item 27d - Schedule of Reportable Transactions for the 
year ended August 31, 1994, are presented for the purpose of additional 
analysis and are not a required part of the basic financial statements but are 
supplementary information required by the Department of Labor's Rules and 
Regulations for Reporting and Disclosure under the Employee Retirement Income 
Security Act of 1974.  These supplemental schedules are the responsibility of 
the Plan's management.  Such supplemental schedules have been subjected to the 
auditing procedures applied in our audit of the basic 1994 financial statements 
and, in our opinion, are fairly stated in all material respects when considered 
in relation to the basic financial statements taken as a whole.

of the Southwestern Public Service Company Tax Benefit Plan and Trust (the 
Plan) as of August 31, 1993, and the related statement of changes in net assets 
available for benefits for the year then ended.  These financial statements are

SOUTHWESTERN PUBLIC SERVICE COMPANY
TAX BENEFIT PLAN AND TRUST
NOTES TO FINANCIAL STATEMENTS
YEARS ENDED AUGUST 31, 1994 AND 1993
1.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation 

The accompanying financial statements of the Southwestern Public Service 
Company Tax Benefit Plan and Trust (the Plan) have been prepared on the 
accrual basis of accounting.

Investment 

The investment in Southwestern Public Service Company (Company or 
Employer) common stock is stated at fair value, based on the New York 
Stock Exchange published market quotations as of the last business day 
of the Plan's fiscal year.  The change in the difference between fair 
value and the cost of investments, including realized gains or losses, 
is reflected in the statement of changes in net assets available for 
benefits as net appreciation (depreciation) in fair value of investments 
during the year.

Securities transactions are recognized on the trade date (the date the 
order to buy or sell is executed).  Dividend income is recorded on the 
ex-dividend date.

Trust Management 

Boatmen's National Bank of Amarillo (the Trustee) manages the assets of 
the Plan under the terms of a trust agreement.

2.	DESCRIPTION OF THE PLAN

The following brief description of the Plan is provided for general 
information only.  Participants should refer to the Plan Agreement for 
more complete information.

General 

The Plan is a defined contribution plan established in 1985 to provide 
eligible employees with an opportunity to defer a portion of their 
pretax compensation and to encourage additional ownership of Company 
common stock.  Benefits are based on employee contributions.  The Plan 
is subject to the provisions of the Employee Retirement Income Security 
Act of 1974.  The Plan is administered by an Administrative Committee 
appointed by the Company's Board of Directors.

Contributions

The Plan was established to conform with the guidelines set forth in 
Internal Revenue Code (the Code) Section 401(k) and other laws and 
regulations relating to qualified plans.  Employees are eligible for 
participation upon completion of one year of service.

The amount of the Company's annual contribution to the Plan is 
discretionary.  However, the Employer's contribution for any year, 
including payment of related administrative and investment expenses paid 
by the Company, cannot exceed the amount of federal income tax benefit 
to the Company resulting from the deduction for cash dividends paid by 
the Company on shares of Company common stock owned by the Southwestern 
Public Service Company Employee Stock Ownership Plan (ESOP) and the 
additional tax benefit resulting from the Employer's contribution to the 
Plan and the ESOP.

The Company contributed to the Plan 25% of the maximum contribution 
described above, reduced by combined administrative and investment 
expenses of the Plan and the ESOP of approximately $162,000 and $123,000 
in 1994 and 1993, respectively.  The remaining 75% was contributed to 
the ESOP.

Contributions by employees are limited to 6% of base salary per pay 
period in addition to the amount which is received in dividends from the 
ESOP.  Pursuant to the Code, an employee's before-tax voluntary 
contribution to his account may not exceed $9,240 for 1994 and $8,994 
for 1993.

Annual additions to a participant's account may not exceed the lesser of 
25% of the participant's compensation for the year or $30,000.  This 
limitation applies to the total Employer contributions allocated to a 
participant for all defined contribution plans of the Employer.

Vesting 

Employees are fully vested in their contributions and are fully vested 
in their pro rata share of the Employer's contributions.

Distributions 

The Plan provides that, upon termination of employment for any reason, 
distributions of benefits to participants which are less than $3,500 are 
to be made within a reasonable time following termination, generally not 
to exceed 60 days following the close of the plan year in which such 
termination occurs.  Distributions of benefits to participants which 
exceed $3,500 are generally made when the participant reaches age 65.  
However, terminated participants may provide a written request to the 
Administrative Committee to receive benefits at an earlier date.
Distributions are made in full shares of Company common stock and cash 
for any partial shares.

Amounts due to terminated participants of the Plan as of August 31, 1994 
and 1993, were approximately $2,206,000 and $1,855,000, respectively.

Allocations 

Employer contributions are allocated in the proportion each 
participant's contribution to the Plan bears to the contributions of all 
participants.  In allocating Employer contributions to individual 
participants' accounts, the amount of a participant's contribution that 
can be considered is limited to 6% of such participant's annual 
compensation.

Termination of the Plan

The Plan may be terminated at any time by the Employer.  In the event of 
termination, the Plan's Administrative Committee shall direct the 
Trustee to distribute the assets remaining in the Plan to participants 
and beneficiaries in proportion to their respective account balances.  
The Employer has no intentions of terminating the Plan nor is aware of 
any occurrences that could result in the termination of the Plan.




Administrative and Investment Expenses

The Plan provides that administrative expenses may be paid by the Plan; 
however, administrative expenses and fees incurred in connection with 
the investment of funds for both the Plan and the ESOP have been paid by 
the Company in 1994 and 1993, and such amounts have reduced the amount 
of the Employer contribution to the Plan, as previously described.  
Included in that amount are reimbursements of certain personnel-related 
expenses incurred by the Company.

3.	FEDERAL INCOME TAXES

The Internal Revenue Service issued its latest determination letter 
dated January 29, 1990, which stated that the Plan is a qualified plan 
under Section 401(a) of the Code, and the Trust, which forms part of the 
qualified Plan, is exempt from federal income taxes under Section 501(a) 
of the Code.  The Plan has been amended since receiving the latest 
determination letter.  A determination letter request is currently 
pending with the Internal Revenue Service to cover these amendments made 
to the Plan as required by recent legislative changes.  In the opinion 
of the plan administrator, the Plan and its underlying trust have 
operated within the terms of the Plan and remain qualified under the 
applicable provisions of the Code.

4.	PLAN AMENDMENTS

The Plan will be amended from time to time, as required, to comply with 
legal requirements upon the advice of the Plan's legal counsel.  Other 
amendments may be necessary to ensure that the Plan is appropriate 
within the industry and community.  The Plan adopted several amendments 
subsequent to year-end to conform with legal requirements.

5.	SUBSEQUENT EVENT

The Company is proposing to merge the Employee Stock Ownership Plan and 
Trust into the Tax Benefit Plan and Trust effective March 1, 1995.  The 
proposed new plan will provide for two levels of discretionary Company 
contributions: one level, contemplated to equal approximately 25% of the 
tax savings generated by the cash dividends paid to participants, will 
be allocated among all eligible employees on the basis of their base 
compensation.  The second level, contemplated to equal approximately 50% 
of the tax savings, will be allocated to employees on the basis of their 
salary deferrals.  The remaining 25% of the tax savings will be 
available for other uses.
  
Employee salary deferral contributions will be increased to allow all 
participants to contribute from 1% to 15%, subject to legal limits.  In 
addition, employees will also have the opportunity to elect to diversify 
25% of future salary deferral and Company contributions into investments 
other than Company stock.  The remaining 75% of salary deferrals and 
Company contributions will be invested in Company stock.
