C) overnment of Puerto Rico uerto Rico Electric Power Authority October 31, 2017 Mrs. Sue Kelly, President and CEO American Public Power Association 2451 Drive, Suite 1000 Arlington, VA 22202, USA Mr. Tom Kuhn, President Edison Electric Institute 701 Avenue, N.W. Washington, DC. 20004?2696 Dear Sue and Tom: Due to the catastrophic destruction to our electrical infrastructure following hurricanes Irma and Maria, I urgently request your assistance in restoring the electrical infrastructure of the Puerto Rico Electric Power Authority (PREPA). We know the American Public Power Association and the Edison Electric Institute have relationships across the electricity sector on the mainland and request your assistance in bringing resources to Puerto Rico to support power restoration on the island. We also understand that you have relationships with key Federal and state government partners that can help expedite these requests. It is our expectation that crews and resources will be required as soon as possible and ending at a date yet to be determined. Due to the design similarities of our systems and recent experience in undertaking large scale restoration following Superstorm Sandy, we would initially request assistance from New York State public and private utilities, but understand that the scope of damage and need for certain expertise could require additional support from electric companies from across the United States. Public and private utilities from Florida are also available and can mobilize quickly due to distance and transportation logistics between Florida and Puerto Rico. While our requests will likely grow as crews are brought in to work on our system and better assessments of the damage are conducted, at this juncture we are requesting: Chief Executive Of?cer GPO. Box 364267 San Juan. Puerto Rico 00936-4267 787.521.4666 787.521.4665 3mm: pulxr, mam-a! f" Mrs. Sue Kelly Mr. Tom Kuhn Page 2 600 full time equivalent transmission and distribution line workers and associated equipment, including a minimum of 5 helicopters (3 heavy lifting and 2 light for crew transfer to transmission towers), required to support their work in restoring the transmission and distribution systems; and, Management, supervisory, and administrative support with regards to the coordination of the restoration efforts, including, but not limited to: incident command, logistics, housing, transport, and supply chain staff and support. Bear in mind that extensive portions of the transmission lines in Puerto Rico run through rugged mountainous terrain with little or no road access. Also, that there are subcontracted crews in Puerto Rico, including APPA members, that already have mobilized men and heavy equipment, have become familiar with operations and may be at your disposal creating minimal delays in restoration work. We anticipate that due to the duration of the assistance required to repair the damaged infrastructure, additional support may be required once additional specifications, requirements, and logistics are determined. Please confirm back to me your willingness to participate in the effort along with an appointed designee with whom we can work with to make immediate progress in addressing this request.
