A spokesman said: "Our engineers are working extremely hard to restore power to these properties as soon as possible.
"We would like to thank all our customers for their patience and apologise for any inconvenience they are experiencing.
"If you are without power, we would like to provide the following advice:
"Turn off electrical appliances at the socket. This is particularly important for heating or cooking appliances as your power could return at any time and potentially cause a safety hazard if you are absent, asleep or unaware.
"Keep one light switched on so that you know when electricity has returned.
"Check on any vulnerable neighbours and relatives to make sure they are comfortable and well.
"Use battery-powered lamps or torches if possible instead of candles as they are safer.
"Only call 999 in the event of an emergency.
"Please contact our power cut helpline on 0800 668877 any time, night or day, if your power supply has been affected."
