The National Treasury Management Agency said it will auction €1 billion of 10-year bonds on Thursday, as it bids to close in on its minimum fund raising target for the year.
The NTMA has so far raised €12.5 billion of long-term debt.
It plans to issue between €14 billion and €18 billion of bonds in total this year.
Last week, the NTMA also announced plans to issue Ireland's first Green Bond in the coming months, subject to market conditions.
Green Bonds remain a relatively new feature of the sovereign debt market. In the EU only France, Belgium and Poland have issued them so far.
The NTMA said it intends to engage with potential investors on a targeted roadshow over the coming weeks.
Frank O'Connor, the NTMA's Director of Funding and Debt Management, said the agency's strategy is to expand its investor base by geography, investor type and product.
"The issuance of Green Bonds enables Ireland to access a new and growing pool of capital," he added.
