Disconnecting computers used in power plants and electrical grids from the internet is being proposed in a bill before the Senate, according to The Hill.

A subcommittee of the Senate Committee on Energy and Natural Resources will hold a hearing on July 12 to discuss the Securing Energy Infrastructure Act, which proposes moving offline most critical components of the nation's critical infrastructure.

Introduced on June 6 by Sens. Angus King (I-Maine), Susan Collins (R-Maine), Martin Heinrich (D-N.M.), and Jim Risch (R-Idaho), the bill seeks to replace computer-connected components with analogue ones as a means to reduce the attack surface for potential intruders.

“National security officials and cyberexperts have repeatedly warned us about the dangerous impact a cyberattack could have on major components of our national infrastructure, like our electric grid,” said Sen. King in a statement.

This approach was helpful when the Ukraine's grid was targeted, the senators said.
