Coalition leaders and senior ministers will meet this morning to sign off on the €100bn revised National Development Plan.
The blueprint for infrastructure spending will be announced tomorrow along with the Summer Economic Statement.
Housing, transport, energy and water services will be funded from the new National Development Plan.
Minister for Public Expenditure Jack Chambers said it will amount to €100bn from 2026 to 2030, along with the promise of another €100bn for the following five years.
The aim is to address shortfalls in services and utilities while also shoring up Ireland’s competitiveness.
Tánaiste Simon Harris said the new plan will signal a step change in infrastructure investment.
Headline figures will be announced tomorrow, with the allocations for departments and utilities set out.
However, the full list of projects will not be confirmed for several months.
“I think it’s important that people are aware that the backdrop against which the Summer Economic Statement will be published this year will be very, very different from previous years,” Mr Harris said.
He added: “We are endeavouring to put together a set of economic projections at a time of huge global uncertainty.
“So, it is going to be necessary to be prudent in the figures we publish and to make decisions in the weeks and months ahead that have a real focus on protecting jobs and investment and keeping our country safe during what could be an economically turbulent period ahead.”
