In idiomaticEnglish, "the powers that be" is a phrase used to refer to those individuals or groups who collectively hold authority over a particular domain. It is a plurale tantum where "be" is the archaic alternative form of "are"; the singular equivalent, "the power that is," is less commonly used. The Powers That Were (TPTW) is also another derivation that is used.
Some examples of "powers that be" are:
Governments, both central and local, and the accompanying civil service
The upper management of a business
Those who control the dissemination of information
