BACKGROUND The American Samoa Power Authority is a multi function public utility that provides electric power, water, waste water, and solid waste services. In addition, the ASPA is also a fuel distributor. On September 29, 2009, an earthquake and tsunami destroyed the ASPA Satala Power Plant that provided approximately one half of the power generation capacity in American Samoa. The U.S. Federal Emergency Management Agency (FEMA), the ASPA, and the American Samoa Government (ASG) provided temporary power. However, this power was very difficult to manage and power was not fully restored to all customers. The ASPA, with approval from the U.S. Federal Emergency Management Agency (FEMA), issued an Invitation for Bids to install a Temporary Turnkey Power Generation Capacity until the Satala Power Plant could be rebuilt or relocated. The Temporary Power generated was connected to the grid. Based on the IFB responses and Source Evaluation Board deliberations, Aggreko International was awarded the bid and contracted to provide temporary turnkey power generation service. The American Samoa Power Authority seeks to replace the Temporary Turnkey Power Generation capacity by June 30, The ASPA is in the process of procuring the 18 MW of TIELINE RFP Page 9

10 Modular and Portable Generator capacity with Switchgear and Protection systems also Modular and Portable. The 18MW Generation System and Switchgear will be located close to the Satala Feeders connection vaults. The ASPA will be responsible for pulling the cabling between the locations of the Temporary Power Generation systems and the Satala Feeders connection vaults and to the new TEILINE Substation equipment. The 18MW Generation System and Switchgear are not part of this RFP. The project is in two locations the Satala Power plant site will have two transformers and one switchgear assembly while the Tafuna would hold the second half of the system. The American Samoa Power Authority seeks to replace the damaged TIELINE transformers and associated switchgear in accordance with the Milestone schedule in section V. III.
