Officials from the city's office of emergency management, as well as from Baltimore Gas & Electric, are on the scene.
Moses Glover, who lives in the neighbourhood, told the Baltimore Sun that he was in his bedroom when he heard a loud boom outside his house. When he went to his window to investigate, a second explosion knocked him to the ground.
"It knocked me across the bed," Mr Glover said. "I came downstairs and saw all of the front of the houses across the street, they were on the ground. I had a picture window downstairs, the glass is in the chair now."
According to CNN, Baltimore Mayor Bernard Young is aware of the explosion and is in a meeting with city officials about the situation.
Governor Larry Hogan offered a statement about the explosion on Twitter.
"We are closely monitoring the situation in northwest Baltimore following this morning’s horrific explosion," he wrote. "We have reached out to offer our full support to the ongoing response and recovery efforts, and are deeply grateful to the first responders on the scene."
