Renegy Signs Letter of Intent to Acquire Operating 20 MW Biomass Power Generation Facility

Renegy Holdings, Inc. (Renegy) (Nasdaq: RNGY), a renewable energy company focused on acquiring, developing and operating a growing portfolio of biomass to electricity power generation facilities, announced today that it has signed a non-binding Letter of Intent ("LOI'') for the acquisition of a 20 megawatt ("MW'') biomass power plant from Sierra Pacific Industries ("SPI'') for $13.0 million. The plant operates in Loyalton, California and currently sells 10 MW of its electrical power output to Sierra Pacific Power ("SPP''), a leading electric utility company serving northern Nevada and northeastern California.

"The Loyalton plant will provide us with an additional source of revenue and anticipated positive cash flow from the plant during the second half of 2008,'' stated Bob Worsley, chairman and CEO of Renegy. "Acquiring this plant, together with the Ione plant that we announced last week, will increase the electrical power output capacity of our portfolio of biomass power generating assets to 75 MW, and advance us toward our goal of building the operating critical mass necessary for Renegy to become a self-sustaining business beginning in 2009. We previously purchased a biomass facility located in Susanville, California from SPI, and are pleased that our growing relationship has yielded another economically-compelling growth opportunity for us that also supports SPI's interest in divesting its non-core business assets. Our agreement with SPI will also provide for a supply of wood waste from SPI's sawmill and other timber-related operations to supplement the fuel requirements of both the Loyalton and Susanville plants. Furthermore, the Northern California fuel zone that we plan to implement to manage the fuel requirements of our Susanville and Ione plants will also support the Loyalton facility. Having a single, centralized fuel aggregation infrastructure that can supply multiple biomass facilities will allow us to realize significant cost efficiencies across our California plant operations.''

Under the terms of the LOI, the sale will also include approximately 50 acres of land at the Loyalton plant site along with existing fuel contracts and all operating and environmental permits for the plant. Renegy expects the transaction to close by June 30, 2008, subject to its completion of final due diligence, entering into a definitive purchase agreement for the plant, and other closing conditions. Renegy will provide partial payments toward the purchase price upon execution of a definitive purchase agreement and upon the closing of the transaction. Payment of the substantial majority of the purchase price will not be due until December 31, 2008.

Fuel for the Loyalton plant is comprised primarily of wood waste provided through long-term contracts with local suppliers. Fifty percent of the fuel is currently derived from sawmills and other forest residue from the surrounding area, and the other fifty percent is derived from municipal wood waste accumulating in nearby landfills. To further supplement its fuel supply, Renegy's fuel aggregation team is currently in negotiations with a large waste management company in the area, and plans to actively explore opportunities to procure forest-derived fuel from U.S. Forest Service lands. Renegy is also currently in discussions with SPP to renegotiate the terms of the existing power purchase agreement for the Loyalton plant. Upon the closing of the acquisition, Renegy intends to hire the current staff at the plant, consisting of approximately 18 operating personnel and a seasoned plant manager with more than 14 years of biomass fuel procurement, plant operations and permitting expertise.
