                           DEFERRED COMPENSATION PLAN

Eligibility and Purpose

         The Northern States Power Company Deferred Compensation Plan permits
directors to defer compensation for performance of services as a director of the
Company. Each director of the Company who is not receiving compensation as an
employee of the Company is eligible to participate.

1.       Election to Defer Compensation

         1.01     Time of Election. The election to defer compensation shall be
made in advance of election to the Board of Directors and, if during a term of
office, in advance of any anniversary date of election by the shareholders.

         1.02     Period of Election. An election to defer compensation shall be
applicable to services beginning immediately after election to term of an office
or, if during a term of office, immediately after any anniversary of such
election. The deferral shall continue until the termination of service as a
director or may be terminated prior thereto by notice to discontinue deferral at
the end of any term of office or anniversary of election by the shareholders to
a term of office.

         1.03     Amount of Deferral. An election for deferral may include all
or a specified portion of compensation expressed as a monthly amount or as a
percentage of compensation, or in either case, within a category of
compensation. A deferral may not include reimbursable expenses.

         1.04     Notices for Deferrals. An election to defer compensation shall
be made on a form provided by the Company. A notice to discontinue deferral
shall be in writing. The election form and any notice to discontinue deferral
shall be delivered or mailed to the Secretary of the Company.

2.       Account Accrual and Disbursement.

         2.01     Deferred Compensation Account. The Company will maintain an

payment of a lump-sum or commencement of installment payments, an additional
amount shall be credited to the account at the end of each calendar quarter at
the following rate:

         The average of the rate at which 30 day U. S. Treasury Bills are sold
in the first auction of each month during a calendar quarter plus 100 basis
points, which rate on an annualized basis shall be applied:

                  a)       to the account balance at the beginning of the
                  quarter; and

                  b)       to any deferred compensation accruing to the account
                  during the quarter from the date of such accrual.

         2.02     Election of Distribution. The method and schedule of payment
of a deferred account may be changed for future accruals beginning immediately
after any annual meeting of shareholders. Changes in the amount and schedule of
payments may be made after the beginning of any annual period as provided in
Section 2.04.

         2.03     Payment of Deferred Account

                  a)       If a lump-sum payment is elected, the payment may be
                  made not earlier than January 15 of the year following
                  termination of service as a director.

                  b)       If installment payments are selected, and no other
                  schedule of payment is selected, the account will be paid in
                  quarterly payments in amounts equal to 1/20th of the account
                  balance at the end of the year in which service as a director
                  is terminated beginning on the succeeding January 15 until
                  fully paid.

                  c)       If alternative installment payments are elected, the
                  schedule of payments shall conform the following criteria:

                           (1)      The payment schedule shall provide for
                           payments each calendar quarter in amounts not less
                           than 1/20th or monthly payments of not less than

                           balance at the end of the calendar quarter
                           immediately preceding the first payment.

                           (2)      The payments shall begin not earlier than
                           January 15 of the year following termination of
                           service as a director.

                           (3)      The payments shall commence not later than
                           the 15th day of the first month of the calendar
                           quarter following the attainment of age 72.

                  Payments shall be made on the 15th day of each calendar
                  quarter of the 15th day of each month, as applicable.

         2.04     Special Distribution. A change in the distribution of a
Participant's accrued account may be requested in writing to the Company by:

                  a Participant;

                  a beneficiary of the Participant after
                    Participant's death; or

                  in the event of the mental disability of a
                    Participant, the personal representative or
                    in the absence thereof, the next of kin of
                    a Participant.

         If the request is made before the calendar year in which a lump-sum
distribution was to be made or in which installment payments were to begin, the
requested change in distribution shall be granted provided the request conforms
to the criteria in Section 2.03(c).

         If the request occurs later than the year before a lump-sum
distribution was to be made or in which installment payments were to begin, the
request shall be referred to the Committee of the Board of Directors which is
responsible for recommending pay levels for senior officers of the Company. If
the Committee determines that the failure to grant the request would result in
financial hardship, the Committee shall grant such request to the extent of the
financial hardship.
