Amazon says it will spend $20 billion on two data center complexes in Pennsylvania, including one it is building alongside a nuclear power plant that has drawn federal scrutiny.

Amazon plans to invest at least $20 billion in the construction of multiple data center complexes in Pennsylvania, marking what officials called the largest private sector investment in the state’s history.
