The Secretary of Defense may not transfer ownership of any power generation infrastructure or power transmission infrastructure located in Guam to the Guam Power Authority until the Secretary certifies to the congressional defense committees that such infrastructure is sufficient to meet projected mission requirements of the Department of Defense for power generation and transmission capacity in Guam through fiscal year 2036.
(b) Underground transmission requirement
Not less than 50 percent of the total linear miles of power transmission lines transferred to the Guam Power Authority pursuant to any agreement with the Secretary of Defense shall consist of underground transmission lines.

This paragraph shall apply to infrastructure owned by the Secretary of Defense, including infrastructure that is currently leased to, operated by, or otherwise made available for use by the Guam Power Authority.
