AWS Scales Corporate PPAs To Fuel Ireland’s AI Growth

The rise of AI is inseparable from the growth of data centres and the environmental footprint that comes with them. Pressure on energy and water use is intensifying as the sector expands.

Governments are responding with new rules aimed at limiting impacts while sustaining digital growth. Ireland is one of the clearest test beds for this balance.

In 2023, the Commission for the Regulation of Utilities ruled that future data centres must meet 80% of their power from additional Irish renewable plants.

The decision divides opinion across energy and technology circles. Some see constraint; others see a catalyst for new capacity.

Niamh Gallagher, AWS’s Country Lead for Ireland and Infrastructure & Public Policy Lead for EMEA at AWS, frames it as opportunity.

Speaking at Wind Energy Ireland’s conference in Dublin, Ireland, Niamh says the policy creates “structured long-term demand” for new renewable generation.

That demand signals bankable projects and a clearer route to delivery. It also sets expectations for developers and buyers on timing and scale.

PPAs turn intent into investment

Power purchase agreements (PPAs) are the main way demand becomes steel in the ground. Under PPAs, companies commit to buy power from wind or solar projects for between 10 and 20 years.

The buyer locks in price certainty and the developer secures the revenues needed to finance construction. Niamh says CPPAs convert ambition into “bankable megawatts”.

These contracts help address finance bottlenecks on large projects. Predictable cash flows lower the cost of capital and speed up build programmes.

Ireland targets 5GW of offshore wind by 2030, a goal now widely seen as at risk. PPAs can bridge part of the gap while permitting and grid upgrades progress.

Scaling renewable capacity

Individual offshore and onshore projects cost billions of euros. Bankability remains one of the hardest hurdles to clear.

Long-term offtake gives lenders confidence that projects will repay. It also helps align delivery schedules with grid connection windows.

Fixed-price contracts manage volatility for buyers and developers. They also support local supply chains and skills.

For the Irish system operator, visible pipelines aid planning for grid reinforcements. That includes prioritising nodes where new renewables can connect with fewer constraints.

Amazon’s market role

Amazon is one of the largest hyperscalers globally with a significant presence in data centres. It is also the world’s largest corporate buyer of renewable energy with more than 600 wind and solar projects totalling 40GW.

In Ireland, Amazon has PPA deals covering 310MW and targets up to 800MW. That is roughly equivalent to two conventional power plants.

Partnerships include Bord na Móna’s Derrinlough wind farm in County Offaly. Niamh says the site can generate enough electricity to power 90,000 homes.

Niamh adds that corporate deals deliver projects “on time, on budget and with no subsidies and at no cost to the taxpayer”. 

The message appeals to policymakers even as critics note it also serves Amazon’s case for data centre growth as a public good.

Public debate on data centres

Data centre energy use sparks scrutiny amid climate goals and household bills. The conversation is active across policy and community forums.

Niamh argues the technology hosted in data centres reduces energy and carbon elsewhere. 

She cited a recent finding by Spanish energy giant Iberdrola, which reports Amazon’s systems help it cut operating costs by between 10% and 30%, with savings passed on to customers.

The net-impact debate now turns on delivery and evidence. Transparent reporting and system-level studies will matter.

“Ireland has the wind, the policy direction and the demand. Now it is about delivery,” says Niamh.
