The firm said the electricity network had been extensively damaged and the worst hit areas were Ceredigion, northern Powys, Gwynedd and the Conwy Valley.
A spokeswoman said: "We are continuing into tonight to work on repairing the network and have restored power to a further 4,000 customers, 3,000 in Wales and 1,000 in Cheshire.
"We will continue to restore more customers throughout the evening. However there will be some customers who will remain without power overnight.
"We will be working into tonight and through tomorrow to get all our customers back on supply."
The company said anyone still experiencing problems once their power was restored should contact 0845 272 2424.
