; or (B) for transformers described in subsection (a)(2)(B)(i), as selected from a table of default values as determined by the Secretary in consultation with applicable industry; and (5) that the qualified energy inefficient transformer has been permanently decommissioned and scrapped. (d) Authorized amount of rebate The amount of a rebate provided under this section shall be— (1) for a 3-phase or single-phase transformer with a capacity of not less than 10 and not greater than 2,500 kilovolt-amperes, twice the amount equal to the difference in watts between the core loss value (as measured in accordance with paragraphs (2) and (4) of subsection (c)) of— (A) the qualified energy inefficient transformer; and (B) the qualified energy efficient transformer; or (2) for a transformer described in subsection (a)(2)(B)(i), the amount determined using a table of default rebate values by rated transformer output, as measured in kilovolt-amperes, as determined by the Secretary in consultation with applicable industry. (e) Authorization of appropriations There is authorized to be appropriated to carry out this section $10,000,000 for each of fiscal years 2018 through 2022, to remain available until expended. 4 Strategic Transformer Reserve Program 31401. Strategic Transformer Reserve Program (a) Establishment The Secretary of Energy shall establish a program to reduce the vulnerability of the electric grid to physical attack, cyber attack, electromagnetic pulse, geomagnetic disturbances, severe weather, climate change, and seismic events, including by— (1) ensuring that large power transformers, generator step-up transformers, and other critical electric grid equipment are strategically located to ensure timely replacement of such equipment as may be necessary to restore electric grid function rapidly in the event of severe damage to the electric grid due to physical attack, cyber attack, electromagnetic pulse, geomagnetic disturbances, severe weather, climate change, or seismic events
