B -- CALAMA WIND FARM PROJECT IN CHILE DUE 050900 POC Evangela Kunene, USTDA, 1621 N. Kent Street, Suite 300, Arlington, VA 22209-2131, Tel: (703) 875-4357, Fax: (703) 875-4009 The Grantee invites submission of qualifications and proposal data (collectively referred to as the "Proposal") from interested U.S. firms which are qualified on the basis of experience and capability to develop a feasibility study for the development of a 37.5 MW wind farm to be located near the city of Calama in the desert region of Antofagasta in northern Chile. The proposed project is a 37.5 MW wind farm to be located near the city of Calama in the desert region of Antofagasta in northern Chile. The wind facility would consist of 50 turbines of 750 kW nominal. These turbines are the most suitable for the wind profile existing in the site being tentatively planned. The proposed site has an average speed of 8 m/s or 18 miles per hour. The wind speeds that have been recorded are positive and the preliminary studies have indicated that the site has favorable wind resources and should be studied and evaluated further. CODELCO contracted Zond Energy to conduct a pre-feasibility study two years ago. The study made positive recommendations but due to the lapse of time, many of the recommendations and follow on feasibility study recommendations need to be enhanced and some further analysis conducted to update the recommendations of Zond. Wind projects are expected to have a life span of 20-30 years, mainly determined by the useful life of the equipment of the plant. For the purpose of analysis CODELCO has used a 20 year life span for the proposed project. The project will require engineering, construction and equipment procurement that has been estimated at $37.5 million by CODELCO. This figure is approximately $1,000 per kW of installed capacity. Due to existing infrastructure such as roads and the relatively inexpensive land available, the total project cost is slightly less than has been the case for similar projects developed elsewhere in the world. However, almost all of the equipment and engineering services would be imported during the implementation of the project. Previous studies and initial wind measurements have indicated favorable wind resources in the proposed northern region of Chile as well as in parts of southern Chile. CODELCO has been working to develop this project and introduce wind energy as an alternative energy source for power generation in Chile. The feasibility study for the Calama Wind Farm will allow CODELCO to take the next step in development of this important renewable energy project in Chile and provide them with an overall project plan and schedule for engineering, including micro siting, design, procurement, and construction of the Calama Wind Farm. Specific tasks for the feasibility study include the following: Verification of Resource Data; Quantification of Emissions Offsets; Preparation of Carbon Verification/Certification Protocol; Development of Contractual and Financial Project Structures; Confirmation of Existing Electrical/Utility Interface Designs; Identification of Hardware Requirements and Procurement Process; q Preparation of the Financial proformas; Identification ofFinancial and Development Support for Project; Documentation of Utility and Regulatory Support for Project; Preparation of TOR for Project EIA and Approval; Evaluation of Project Risks and Critical Success Factors The U.S. firm selected will be paid in U.S. dollars from a $275,000 grant to the Grantee from the U.S. Trade and Development Agency (TDA). A detailed Request for Proposals (RFP), which includes requirements for the Proposal, the Terms of Reference, and a background definitional mission report are available from TDA, at 1621 N. Kent Street, Suite 300, Arlington, VA 22209-2131. Requests for the RFP should be faxed to the IRC, TDA at 703-875-4009. In the fax, please include your firm's name, contact person, address, and telephone number. Some firms have found that RFP materials sent by U.S. mail do not reach them in time for preparation of an adequate response. Firms that want TDA to use an overnight delivery service should include the name of the delivery service and your firm's account number in therequest for the RFP. Firms that want to send a courier to TDA to retrieve the RFP should allow one hour after faxing the request to TDA before scheduling a pick-up. Please note that no telephone requests for the RFP will be honored. Please check your internal fax verification receipt. Because of the large number of RFP requests, TDA cannot respond to requests for fax verification. Requests for RFPs received before 4:00 PM will be mailed the same day. Requests received after 4:00 PM will be mailed the following day. Please check with your courier and/or mail room before calling TDA. Only U.S. firms and individuals may bid on this TDA financed activity. Interested firms, their subcontractors and employees of all participants must qualify under TDA's nationality requirements as of the due date for submission of qualifications and proposals and, if selected to carry out the TDA-financed activity, must continue to meet such requirements throughout the duration of the TDA-financed activity. All goods and services to be provided by the selected firm shall have their nationality, source and origin in the U.S. or host country. The U.S. firm may use subcontractors from the host country for up to 20 percent of the TDA grant amount. Details of TDA's nationality requirements and mandatory contract clauses are also included in the RFP. Interested U.S. firms should submit their Proposal in Spanish and English directly to the Grantee by 5:00 p.m., May 9, 2000 at the above address. Evaluation criteria for the Proposal are included in the RFP. Price will not be a factor in contractor selection, and therefore, cost proposals should NOT be submitted. The Grantee reserves the right to reject any and/or all Proposals. The Grantee also reserves the right to contract with the selected firm for subsequent work related to the project. The Grantee is not bound to pay for any costs associated with the preparation and submission of Proposals.****** Posted 03/29/00 (W-SN439273). (0089)
