HECO Exhibit 10.6(a)

         Amendment No. 1 to "Power Purchase Contract Between Hawaiian
             Electric Co., Inc. and the City & County of Honolulu
                             Dated March 10, 1986

By mutual agreement, Appendix D of the subject Contract is hereby amended to
reflect that energy furnished by the Seller to the Company shall be in
accordance with the following revised limitations:

1.   Except as limited in accordance with Section 8, Appendix A, during the
     months of June through November, there shall be no off-peak maximum rate of
     energy delivery, except for circumstances wherein the Company experiences a
     specific equipment problem which makes it technically impossible for the
     Company to take the level of output desired by the Seller.  In any such
     circumstances, the Company shall promptly notify the Seller of the specific
     problem and use its best efforts to allow restoration of the level of
     output desired by the Seller in a timely manner.

2.   During off-peak hours, the Company shall accept from the Seller during the
     months of December through May, on Monday through Friday up to 40 MW and on
     Saturday, Sunday, and holidays up to 25 MW.  The maximum off-leak dispatch
     levels noted in this subparagraph 2 shall also be subject to the same
     exception for equipment problems of the Company noted in subparagraph 1
     above, but may also be raised if the Company has a normally base-loaded
     unit off-line for overhaul.

3.   To enhance the Company's ability to accept energy from the Seller, Seller
     agrees to notify the Company by noon on Wednesday of each week of the
     expected hourly dispatch level of the Seller's facility for the coming
     week.  If the Seller so desires it and the circumstances permit it, the
     Company may waive the limitations noted above on a week-to-week basis.

This Amendment covers dispatch levels only and is in no way intended to affect
the pricing mechanisms established in the Contract.
