                                Explanatory Note

       On December 3, 1999, Scottish Power plc (the "Registrant") filed a
Registration Statement on Form S-8 (Registration No. 333-92095) which
registered 35,717,000 Scottish Power plc ordinary shares reserved for issuance
under three plans of its indirect, wholly owned subsidiary, PacifiCorp.  The
Registrant also registered an indeterminate amount of plan interests under the
PacifiCorp K Plus Employee Savings and Stock Ownership Plan (the "401(k) Plan")
and under the PacifiCorp Compensation Reduction Plan dated December 1, 1994
(the "Compensation Reduction Plan").

       In connection with the sale of all of the outstanding shares of Common
Stock of PacifiCorp to MidAmerican Energy Holding Company, which closed on
March 21, 2006, the Registrant's American Depositary Shares (each of which
comprises four ordinary shares of the Registrant) are no longer being offered
under the 401(k) Plan or under the Compensation Reduction Plan.  This
post-effective Amendment No. 1 to the Registration Statement on Form S-8
deregisters all 401(k) Plan interests and all Compensation Reduction Plan
interests.
