Item 5. Other Events
- --------------------

        On April 15, 2002, Nevada Power Company (the "Company") filed a
Petition for Reconsideration of Certain Findings (the "Petition") with the
Public Utilities Commission of Nevada ("PUCN"), seeking reconsideration of the
recent decisions of the PUCN with respect to the Company's general rate case,
PUCN Docket No. 01-10001, and the Company's application for approval of new
revised depreciation rates, PUCN Docket No. 01-10002. In the Petition, the
Company raised six issues for reconsideration: the treatment of revenues related
to SO2 Allowances, in particular the calculation of the annual amortization
amount, which appears to be in error; the adjustment for "excess" capital
investment related to common facilities at the Harry Allen generating station;
the rejection of adjustments to accumulated depreciation reserves related to the
establishment of revised depreciation rates for transmission, distribution and
common facilities; the delay in allowing the Company to recover its merger costs
without the benefit of carrying charges; the finding that the Company has no
need for and is entitled to zero funds cash working capital; and the
establishment of a 10.1 percent return on equity.

        At this time, the Company cannot predict how long it will take for the
Petition to be heard or the outcome of the proceeding. A copy of the Company's
April 15, 2002 filing is attached hereto as Exhibit 99.1.

        The undersigned registrants hereby clarify their Current Reports on
Form 8-K, dated April 11, 2002, filed on April 15, 2002, regarding the Company's
lawsuit against the PUCN with respect to the PUCN's decision on the Company's
deferred energy rate case. The lawsuit was filed in the First Judicial District
Court of the State of Nevada in and for Carson City, and not in Federal District
Court as was inadvertently stated in the prior Current Reports on Form 8-K.
