1. EQUIPMENT OVERVIEW

The equipment being made available for purchase is a GE MS6001B Gas Turbine 33 MW Power Generation Package with Deltak heat recovery steam generator. Steam capacity is nominally 280Klbsm/hr @ 410psig/640F. For detailed equipment information reference Table 2.

2. EQUIPMENT STATUS

The cogeneration facility was operating satisfactorily when it was shutdown in February of 2004 by the equipment operator. The equipment was idled when a new power facility was brought on-line. Equipment preparations for a long-term outage were made by the cogeneration facility operator and the details of the equipment preparation are not known. It appears that minimal preparation was performed to preserve the equipment. Some equipment was removed and placed in climate controlled storage such as motors and switchgear. Prospective buyers should perform due diligence and/or assume some maintenance will be required prior to returning equipment to service.

3. EQUIPMENT CONDITION The following information is offered in good faith; however, OWNER DOES NOT MAKE ANY REPRESENTATION OR WARRANTY, EXPRESSED OR IMPLIED, AS TO THE CONDITION OF THE EQUIPMENT, AND SPECIFICALLY MAKES NO REPRESENTATION OR WARRANTY OF MERCHANTABILITY OR OF FITNESS FOR A PARTICULAR PURPOSE. A prospective purchaser of the equipment must conduct its own due diligence as to the condition of the equipment. The equipment will only be made available for purchase on an “AS IS, WHERE IS” basis. Visual inspections and electrical / mechanical test were performed on the major components of the cogeneration facility in March 2009. The inspections and tests were performed to provide a reasonable assessment of the current condition of the equipment. The equipment assessment summary is provided in Table 1 and equipment details are provided in Table 2.
