Electric Ireland said today it would credit the bills of about 10,000 of its registered vulnerable customers with €100 credit each.
The company said the €1m credit will help those in need during the Covid-19 pandemic and is another customer commitment as part of its "Brighter Together Energy Programme" launched earlier this year.
Electric Ireland also announced the extension of its disconnection moratorium which started on October 22 and which will now run until March 1, 2021.
As well as Electric Ireland's 1.1 million residential customers being able to avail of the disconnection moratorium, the scheme will be extended to its business customers.
Marguerite Sayers, Executive Director of Electric Ireland, said the company has almost 10,000 registered vulnerable customers, some of whom are critically dependent on electrically powered equipment.
"We hope this gesture from us will alleviate some pressure at the end of a challenging year," Ms Sayers said.
"We are also acutely aware of the difficulties that some customers are experiencing due to the combined effect of the Covid-19 pandemic, Christmas expenses and winter energy bills," Ms Sayer said.
She said the company has a rigorous engagement process in place to help customers who are facing such difficulties, to ensure they continue to offer them the best support.
"The continuation of our disconnection moratorium until March 2021 means that all of our residential and business customers can also rest assured that they will have the comfort of energy supply in the coming months," she said.
"We are making a promise that we feel proud of - that no home or business will be left in the dark this winter due to payment difficulties," she added.
The ESB executive also urged any customer who is experiencing financial hardship to contact the company, adding that it will work with them to agree a payment plan suited to their individual circumstances.
