Baltimore Gas & Electric (BGE) says its call to conserve electricity has ended, hours after a substation experienced an unplanned disconnection from BGE's electric grid.

Gas and Electric Co. asked customers to conserve energy “immediately” to reduce the chance of widespread power outages Monday afternoon, before ending the request a few hours later, and avoiding widespread blackouts.

In an update on its website, BGE says that "a critical power plant [is] experiencing an unplanned disconnection from the BGE electric system."
