Why Ireland’s €295 Billion Infrastructure Boom by 2050 Could Flip Your Investment Strategy Overnight

Ever wonder what it would feel like if the world’s infrastructure had the ultimate glow-up? Well, hold onto your hard hats, because PwC’s Global Infrastructure Outlook is forecasting a mind-blowing €129.2 trillion investment by 2050—a figure so massive, it’s basically doubling what we spent in the last two decades combined. Yes, you read that right: double. Imagine cities growing, transport networks evolving, and power grids electrifying at a pace that’s nothing short of revolutionary. Transport and power alone will gobble up about half of this gargantuan investment, with annual spending on the move—from rails to airports—set to nearly double. Meanwhile, Ireland is sprinting ahead, turning its infrastructure deficit into an ambitious growth story that’s poised to put it among Europe’s top contenders by mid-century. This isn’t just about plugging gaps; it’s about sparking a transformation that ripples across digital innovation, social hubs, and sustainable energy. Intrigued? You should be—because this unprecedented investment cycle is reshaping how we live, work, and connect, and trust me, the future is already knocking. LEARN MORE

Cumulative global investment in infrastructure is projected to grow to €129.2tn by 2050, according to PwC‘s Global Infrastructure Outlook.

In real terms, the forecast suggests global infrastructure spending over the next 25 years will be double that of the past 20 years, before which comparable data is unavailable.

Annual infrastructure spend forecast to enter “an unprecedented investment cycle” over the next quarter of a century, climbing 55.2% from €3.8tn in 2024 to €5.9tn, with transport and power expected to account for around half of total investment.

As mobility networks modernise and cities grow, annual transport spending will rise from €1.2tn in 2024 to €2.1tn in 2050, representing a cumulative total of €43tn.

Annual spending on both rail and airport infrastructure will nearly double from 2024 levels, with annual airport spending 1.9 times higher in 2050 at €131.9bn, and rail spending 1.8 times higher at €577.5bn in 2050.

Annual spending on power infrastructure will increase from €539.6bn in 2024 to €940bn in 2050, totalling €21.4tn over the period.

Reflecting the pace of electrification, by 2050, annual investment in power storage will be nearly €77.8bn—3.7 times 2024 levels, while transmission and distribution spending will grow 2.6 times to €403.7bn.

In Ireland, annual infrastructure spend will surge 73% from €7.9bn in 2024 to €13.7bn in 2050 and to a cumulative €295bn.

This rise will increase Ireland’s share of infrastructural spend in Europe to 1.8% in 2050, up from 1.4% in 2024 and will make Ireland the 14th largest infrastructure market in Europe by 2050.

This projected spending growth reflects Ireland’s well-publicised infrastructure deficit and the scale of the country’s ambition.

Ireland stands out as one of Europe’s fastest-growing infrastructure markets, with gains in infrastructure spend supported by the National Development Plan.

Ireland’s infrastructure investment out to 2050 will be dominated by digital (€71.8bn), power (€55.6bn), social (€51.3bn), transport (€38.5bn), and water (€34.2bn).

Together, these five sectors account for over 85% of Ireland’s projected total spend on infrastructure.

“Ireland’s infrastructure pipeline is ambitious and needs to be. Public and private investors must work together to deliver the transformative change that is needed over the next couple of decades,” said Rob Costello, capital projects and infrastructure partner at PwC Ireland.

“Investment cannot happen in silos. Developing the digital infrastructure that will drive our economy forward will require significant investment in our energy infrastructure.

“New, sustainable communities will be made possible only through investment in transport, health and education.”

In the three years from 2024 to 2027, annual global investment in data centres is on track to more than double to €215.3bn as the AI arms race intensifies.

Total investment from 2024 to 2032 will top €1.28tn in a remarkable short-term escalation, which will be followed by a period focused on improving the utilisation, efficiency, and adaptability of existing built stock.

Globally, Asia-Pacific will remain the engine of global infrastructure activity, accounting for more than half of total investment to 2050, propelled by urbanisation, industrial expansion and rapid build out of power and digital networks.

Africa will see the world’s fastest-growing infrastructure investment rate, with annual spending to increase nearly 1.8 times by 2050, reflecting demographic change and significant infrastructure gaps.

Europe and North America will enter a period of renewal to replace ageing transport, energy and water systems, with annual infrastructure spending forecast to rise 1.6 times by 2050 across the Americas and 1.4 times in Europe

PwC’s analysis is the first of its kind to offer long-term infrastructure spending forecasts to 2050 for nine sectors, 20 subsectors and 45 countries and territories, which represent 88% of global economic output.

It draws on the last 20 years of spending data and models future spending based on economic and policy factors.

The analysis considers public and private investment in hard infrastructure, including power, transport, telecoms, and water, but excluding spending on housing, capital equipment and plant and machinery.

PwC Ireland — Global infrastructure spending is expected to top €129tn through 2050.

“Ireland’s current infrastructure deficit limits our potential and our quality of life. Investment in infrastructure is a statement of ambition for a better and brighter future, and we must all get behind it,” said Ciarán Nevin, economics director at PwC Ireland.

“Ireland can be transformed for the better over the next 25 years. By investing hundreds of billions of euro in our future, we can decarbonise our energy and transport systems, protect our environment, and enable the industries of tomorrow.”
