Item 8.01. Other Events.

On May 4, 2006, MSW Energy Holdings LLC (“MSW Energy Holdings”) and MSW Energy Finance Co., Inc. (“MSW Finance”) filed with the Securities and Exchange Commission their Quarterly Report on Form 10-Q for the three months ended March 31, 2006 (the “Form 10-Q”). This 8-K contains supplemental financial information concerning MSW Energy Holdings and MSW Finance not included in the Form 10-Q, including certain non-GAAP financial information identified herein.

The information in this Form 8-K is furnished pursuant to Item 8.01 of this Form 8-K and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, or incorporated by reference in any filing under the Securities Act of 1933 or the Securities Exchange Act of 1934, except as shall be expressly set forth by specific reference in such filing.

MSW Energy Holdings, a Delaware limited liability company formed in March 2003, was organized for the purpose of acquiring and holding a 50% interest in Covanta Ref-Fuel Holdings LLC (“Covanta Ref-Fuel”) from Duke Energy Corporation. The initial acquisition of Covanta Ref-Fuel was completed on June 30, 2003 and the second acquisition occurred on September 30, 2005. In order to partially fund this acquisition, MSW Energy Holdings issued $200 million aggregate principal amount of 8 1/2% senior secured notes due September 1, 2010 (“Senior Notes”).

The indenture under which MSW Energy Holdings’ Senior Notes were issued requires, among other things, but subject to certain exceptions, that any restricted payments are not permitted unless certain ratio covenants based on MSW Energy Holdings’ last twelve months proportionate ownership of Covanta Ref-Fuel have been met. The proportionate adjusted data is presented, including proportionate interest expense and proportionate adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”) because these measures are used in the calculation of covenant compliance under such indenture governing the Senior Notes.

These measures which are included in the following tables are unaudited measures which are not prepared in accordance with US generally accepted accounting principles (“GAAP”). They are not intended to supplant the information provided in accordance with GAAP. Furthermore, these measures may not be comparable to those used by other companies. Accordingly, a reconciliation of Adjusted EBITDA to the most directly comparable GAAP measure, operating cash flows, is included. In addition, the ratio of proportionate interest expense to Adjusted EBITDA is an interest coverage ratio under the indenture with respect to which MSW Energy Holdings is not aware of a directly comparable GAAP measure. Accordingly, readers are directed to the computation of proportionate interests and the reconciliation of Adjusted EBITDA to operating cash flows presented below for a reconciliation of such ratio to its GAAP components. The following tables should be read in conjunction with the MSW Energy Holdings’ historical financial statements and related notes contained in the Form 10-Q. The information is being presented for informational purposes only, as it represents the covenant calculation under the Senior Notes.

Additionally, as required under the indenture, the activity of Covanta Ref-Fuel is separate from MSW Energy Holdings’ incremental activity in the following calculations (unaudited, in thousands of dollars):


	For the Twelve
	Months Ended
	March 31, 2006

Proportionate Adjusted EBITDA (1)	$	132,903

Proportionate interest expense (2)		39,781


Ratio of proportionate Adjusted EBITDA to proportionate interest expense (3)		3.3x


(1)		Proportionate Adjusted EBITDA is defined under the indenture as MSW Energy Holdings’ ownership percentage of Covanta Ref-Fuel times Covanta Ref-Fuel’s Adjusted EBITDA. Adjusted EBITDA for Covanta Ref-Fuel (as calculated below) is not a measurement of financial performance under GAAP and should not be considered as an alternative to cash flow from operating activities or as a measure of liquidity or an alternative to net income as indicators of operating performance or any other measures of performance derived in accordance with GAAP. Proportionate Adjusted EBITDA for the twelve months ended March 31, 2006 is calculated by subtracting the three months ended March 31, 2005 from the period of January 1, through June 24, 2005 and then adding the period from June 25, through December 31, 2005 and the three months ended March 31, 2006. (unaudited, dollars in thousands):

MSW Energy Holdings percentage ownership														50.0	%


Proportionate Adjusted EBITDA													$	132,903


(2)		Proportionate interest expense is defined under the indenture as the percentage ownership of the interest expense for Covanta Ref-Fuel plus 100% of incremental MSW Energy Holdings’ interest expense.

The following table reconciles MSW Energy Holdings proportionate interest expense (unaudited, dollars in thousands):


	For the Twelve
	Months Ended
	March 31, 2006

Covanta Ref-Fuel interest expense	$	46,610
MSW Energy Holdings ownership percentage		50.0	%

Covanta Ref-Fuel proportionate interest expense	$	23,305
MSW Energy Holdings incremental interest expense		16,476

MSW Energy Holdings proportionate interest expense	$	39,781


(3)		Proportionate Adjusted EBITDA to proportionate interest expense is defined under the indenture as the quotient of proportionate Adjusted EBITDA divided by proportionate interest expense.

* The levelization of the energy contract relates to the accounting of a long-term power contract, the revenue under which is being recognized in accordance with Emerging Issues Task Force (“EITF”) Issues 96-17 “Revenue Recognition under Long-Term Power Sales Contracts That Contain Both Fixed and Variable Pricing Terms.” EITF 96-17 requires that MSW Energy Holding recognizes power revenues under these contracts as the lesser of (a) amounts billable under the respective contracts; or (b) an amount determinable by the kilowatt hours made available during the period multiplied by the estimated average revenue per kilowatt hour over the term of the contract. The determination of the lesser amount is to be made annually based on the cumulative amounts that would have been recognized had each method been applied consistently from the beginning of the contract. The difference between the amount billed and the amount recognized is included in other long-term liabilities.

A reconciliation of Covanta Ref-Fuel’s Adjusted EBITDA to operating cash flow is provided below, as operating cash flows represent the most comparable GAAP measure of liquidity (unaudited, dollars in thousands).
