UK Power Networks has reported that 290 properties were without power in Rendlesham and surrounding areas, which includes the postcode IP12 2.
The power cut was due to an overhead electricity line fault.
A spokesman for UK Power Networks said: “Specialist engineers from our control room are also working to divert power remotely, so it’s possible your power could come back on at any point. We can’t always restore everyone this way.
“That’s why we’re also sending staff to the area to check our equipment.”
The power has since been restored.
