The purpose of this executive order is to protect the national security of the United States bulk-power system, which provides the electricity that supports national defense, vital emergency services, critical infrastructure and the economy. The order recites that the minimal restrictions on acquisition or operation in the United States of foreign-produced bulk-power system electric equipment increase the ability of some foreign entities to create and exploit vulnerabilities in bulk-power equipment. The order declares a national emergency with respect to that threat, and it prohibits the acquisition, importation, transfer or installation of foreign-produced bulk-power system electric equipment where the transaction involves any property in which any foreign country or national thereof has any interest if the transaction poses an undue risk of sabotage, subversion, unauthorized access, malicious remote action or supply disruption affecting the bulk-power system; poses an undue risk of catastrophic effects on the security or resilience of U.S. critical infrastructure or the economy; or otherwise poses an unacceptable risk to the national security of the United States. Upon making a determination that a transaction presents any of the foregoing risks, the secretary of energy may impose conditions on the continued use, operation, maintenance, servicing or updating of foreign-manufactured or operated bulk-power system electric equipment acquired or installed before the date of the order. The order also allows the secretary of energy to design and negotiate measures to mitigate the concerns identified in the order. Likewise, it allows the secretary of energy to establish criteria and procedures for recognizing particular equipment and vendors in the bulk-power system electric equipment market as prequalified for future transactions. The order also authorizes the secretary of homeland security to (a) take such actions as may be necessary to implement the order; (b) promulgate rules and regulations to carry out the intent of the order; and (c) develop and submit a set of recommended revisions to the Federal Acquisition Regulation (FAR) to ensure that national security risks are adequately considered in any federal procurement concerning energy infrastructure.
