All homes that have been without power following the Christmas storms have been told their electricity will be restored by the end of today.
"I want to thank the ESB staff for their work in restoring power to more than 100,000 homes and businesses over the past two weeks," Mr Rabbitte said.
"While most of us were enjoying the Christmas break, ESB crews were working in very difficult weather conditions to repair the energy system.
"I want to thank the ESB and all emergency workers for their selfless endeavours over the Christmas period. "
It is said emergency repair crews had returned supplies to more than 75,000 customers since storms swept in from St Stephen's Day.
Outages from earlier stormy weather had already been repaired over the last fortnight.
As of this morning, around 800 homes and businesses were still without power.
ESB crews restored supply to around 10,000 customers on Friday alone as more than 500 faults on power lines were repaired.
"Work is progressing since early morning on clearing the remaining faults due to the St Stephen's Day storms on December 26 and 27," ESB said today.
"In the affected areas of the south west and mid west we have crews from all around the country assisting in the efforts.
"As outlined yesterday, this is frustratingly slow work and we thank customers for their patience."
