Exhibit 99.04


UNAUDITED PRO FORMA FINANCIAL INFORMATION

     The following unaudited pro forma financial information adjusts the
historical consolidated balance sheet and statements of income of NSP after
giving effect to their proposed business combination transaction with WEC (the
Transaction) to form Primergy and a new subsidiary structure.  The unaudited
pro forma condensed balance sheet at Dec. 31, 1996 gives effect to the
Transaction as if it had occurred on that date.  The unaudited pro forma
condensed statements of income for each of the three years in the period ended
Dec. 31, 1996 give effect to the Transaction as if it had occurred at Jan. 1,
1994.  These statements are prepared on the basis of accounting for the
Transaction as a pooling of interests and are based on the assumptions set
forth in the notes thereto.

     The following pro forma financial information has been prepared from,
and should be read in conjunction with, the historical consolidated financial
statements and related notes thereto of NSP.  The following information is not
necessarily indicative of the financial position or operating results that
would have occurred had the Transaction been consummated on the date, or at
the beginning of the periods, for which the Transaction is being given effect
nor is it necessarily indicative of future operating results or financial
position. Completion of the Transaction is subject to numerous conditions,
many of which are beyond NSP's control.

New NSP Pro Forma Condensed Information

     The pro forma financial information adjusts the historical financial
statements of NSP after giving effect to the Transaction, including the
reincorporation of NSP in Wisconsin, the merger of the Wisconsin Company into
Wisconsin Energy Company, and the transfer of ownership of all of the current
NSP subsidiaries to Primergy.

NEW NSP

NOTES TO UNAUDITED PRO FORMA CONDENSED FINANCIAL STATEMENTS

1.   NSP common stock with a $2.50 par value will be canceled and replaced
     with common stock of New NSP, which will be issued to Primergy, with the
     same $2.50 par value.  As a result, no pro forma adjustments were
     necessary for stock activity related to the Transaction.

2.   Subsidiary assets, liabilities, equity and results of operations have
     been eliminated from consolidated NSP amounts to reflect the merger of
     NSP-W into Wisconsin Energy Company and the transfer of ownership and
     control of all other subsidiaries from NSP to Primergy.  Primergy's
     equity investment in New NSP is assumed to reflect the reduction in net
     assets related to the merger of NSP-W into Wisconsin Energy Company and
     transfer of investments in other subsidiaries from NSP to Primergy.  

3.   NSP financing of subsidiary capital and cash flow requirements has been
     adjusted to reflect the transfer of such items to Primergy.  Pro forma
     adjustments reflect the elimination of (a) notes receivable and advances
     from subsidiaries; (b) NSP debt incurred to finance the notes and
     advances; (c) interest income earned on the notes and advances; and (d)
     interest expense accrued on the debt incurred to finance the notes and
     advances.

4.   After the Transaction, NSP will not retain ownership of subsidiaries
     currently being consolidated.  Consequently, intercompany transactions
     between NSP and its current subsidiaries have not been eliminated in the
     pro forma financial statements.

     The most significant intercompany transactions are power sales to and
     purchases from the Wisconsin Company pursuant to an interchange
     agreement with NSP.  The interchange pricing and cost sharing
     arrangements are expected to be restructured as a result of the
     Transaction.  However, at this time the amount of any changes to
     interchange power purchases or sales cannot be estimated.  Consequently,
     no pro forma adjustments have been made to operating revenues, operating
     expenses, or accounts receivable from (or payable to) associated
     companies for the effects of interchange restructuring.

5.   The Merger Agreement provides that certain gas utility properties and
     operations in Wisconsin (currently owned by the Wisconsin Company) will
     be transferred to New NSP as part of the Transaction.  Pro forma
     adjustments have not been made for this transfer due to immateriality. 
     As of Dec. 31, 1996, the properties to be transferred include utility
     plant with a net book value of approximately $20 million. For the years
     ended Dec. 31, 1996, 1995 and 1994, the operations to be transferred
     generated revenues of approximately $32 million, $29 million and $27
     million, respectively.  The amount of related operating expenses have
     not been quantified.  This transfer is to ensure compliance with certain
     provisions of the Wisconsin Holding Company Act.  The assets and
     liabilities to be transferred are expected to relate to gas utility
     properties directly contiguous to NSP's utility service territory in
     Minnesota.

6.    Certain reclassifications have been made to the 1995 and 1994 NSP
      Wisconsin Company financial statements to conform with the 1996
      presentation.  These classifications had no effect on net income or   
      earnings per share.

7.    The allocation between NSP and WEC and their customers of the estimated
      cost savings resulting from the Transaction, net of the costs incurred
      to achieve such savings, will be subject to regulatory review and
      approval.  None of these estimated cost savings, the costs to achieve
      such savings, or the transaction costs have been reflected in the pro
      forma condensed financial statements.
