(2) The electric grid faces challenges from 
aging infrastructure and a need for increased elec-
tric power transmission capacity. 
(3) The United States faces a pressing need to 
expand electric power transmission. 
(4) Electric power transmission investments 
will— 
(A) improve resilience by enabling access 
to diverse generation resources across the coun-
try; 
(B) promote economic benefits and create 
new jobs in communities across the country; 
and 
(C) enhance electric grid reliability.
