Airtricity has announced that it will create 200 jobs over the next year as it enters the domestic gas market.
The company said there will be 100 new full-time jobs at its headquarters in Sandyford in Dublin, while the other 100 jobs will be 'outsourced roles'.
Airtricity said the new positions will be in sales, customer support, billing and support services.
Energy Minister Eamon Ryan has welcomed Airtricity's announcement.
'Our policy of competition in the domestic energy market is reaping dividends for the consumer and wider economy.'
Airtricity Managing Director Kevin Greenhorn said the company's investment will provide 'real and sustainable competition' in the energy market and that will benefit customers.
Airtricity says it will be offering customers a 10% discount on Bord Gáis rates.
The company entered the electricity market last year and says it now has 200,000 customers.
