EXHIBIT 99.1

EBITDA represents net income before interest, taxes, depreciation and amortization. EBITDA is presented here because NV Energy, Inc. (the “Company”) considers it a supplemental measure of its performance and believes debt-holders frequently use EBITDA to analyze operating performance and debt service capacity. EBITDA has limitations as an analytical tool, and you should not consider it in isolation, or as a substitute for analysis of our operating results as reported under GAAP. Some of these limitations are:

	•		EBITDA does not reflect cash expenditures, or future requirements for capital expenditures, or contractual commitments;

	•		EBITDA does not reflect changes in, or cash requirements for, working capital needs;

	•		EBITDA does not reflect the significant interest expense, or the cash requirements necessary to service interest or principal payments, on debts;

	•		Although depreciation and amortization are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and EBITDA does not reflect any cash requirements for such replacements; and

	•		Other companies in this industry may calculate EBITDA differently than we do, which will limit its usefulness as a comparative measure.

Because of these limitations, the Company’s management relies primarily on our GAAP results as a measure of the Company’s performance and uses EBITDA on a supplemental basis.
