UK Power Networks is reporting that Storm Eunice has left another 147 customers without power in Glemsford, near Sudbury.
This comes after more than 200 customers in Newmarket suffered a power cut.
The incident was first reported at 10.23am.
UK Power Networks hope to restore electricity to the area between 12pm and 1pm.
Its website says engineers are "currently investigating a high voltage overhead electricity line fault which has caused a power cut in the local area".
It is currently unclear whether this is due to a fallen tree branch bringing down overhead wires near Clare.
