Secure High-voltage Infrastructure for Electricity from Lethal Damage Act or SHIELD Act - Amends the Federal Power Act to authorize the Federal Energy Regulatory Commission (FERC), with or without notice, hearing, or report, to order emergency measures to protect the reliability of either the bulk-power system or the defense critical electric infrastructure whenever the President issues a written directive or determination identifying an imminent grid security threat.
Directs FERC to consult with governmental authorities in Canada and Mexico regarding implementation of emergency measures.
Prescribes: (1) implementation procedures; and (2) related cost recovery measures affecting owners, operators, or users of either the bulk-power system or the defense critical electric infrastructure.
Directs FERC to require any owner, user, or operator of the domestic bulk-power system to implement measures to protect the system against specified vulnerabilities.
Directs FERC also to order the Electric Reliability Organization (ERO) to submit reliability standards to: (1) protect the bulk-power system from a reasonably foreseeable geomagnetic storm event or electromagnetic pulse event (EMP); and (2) require entities that own or operate large transformers to ensure their adequate availability to restore promptly the reliable operation of the bulk-power system in the event of destruction or disability as a result of attack or a geomagnetic storm or EMP.
Directs the Secretary of Energy to establish a program to: (1) develop technical expertise in the protection of electric energy systems against either geomagnetic storms or malicious acts using electronic communications or electromagnetic weapons; and (2) share it with owners, operators, or users of systems for the generation, transmission, or distribution of electric energy located in the United States and with state commissions.
Exempts, for a specified period, the Tennessee Valley Authority and the Bonneville Power Administration from any requirement pertaining to either emergency response measures or measures to address grid security vulnerabilities.
