“[F]iveyearsago,wehadrelativelyflatgrowthintheindustrialsector.…Certainly,data

“10yearsago,everybodythoughta25[megawatt,MW]loadwasbig.These[loads
today]arehuge—725MW.”

Untilrecently,demandintheelectricitysectorwasrelativelystable.Inrecentyears,
however,investmentinlargesourcesofnewload—manufacturingfacilitiesanddata
centers—hasreached$630billion.
