Amazon Leverages Long-Term Demand for Green Supply

Data centres and their energy demands have become a flashpoint for debate in Ireland and beyond. The technology sector faces mounting pressure over electricity consumption at a time when the country struggles to meet climate targets and households face high energy costs.

Last year, Ireland's Commission for the Regulation of Utilities ruled that future data centres must source 80% of their energy from additional Irish renewable power plants. The decision has divided opinion across the energy and technology sectors, with supporters arguing it will accelerate the transition to clean energy whilst critics warn it could constrain growth.

Niamh Gallagher, AWS Country Lead for Ireland and Infrastructure & Public Policy Lead for EMEA, views the regulation differently. Speaking at the Wind Energy Ireland conference in Dublin on Wednesday, she argued the ruling creates "structured long-term demand" for a new generation of renewable energy in Ireland.

How purchase agreements work

The framework most commonly used to meet clean energy requirements is the power purchase agreement. These contracts commit companies to buying large amounts of electricity from wind or solar plants over periods of between 10 to 20 years.

The deals could benefit both buyers and energy providers. Companies secure energy at a fixed price while energy companies obtain the funding necessary to build and maintain installations.

Niamh said CPPAs allow developers to "convert ambition into bankable megawatts". These agreements could matter for Ireland as it works towards ambitious energy targets.

The government aims to install 5GW of offshore wind capacity by 2030. Both industry and state now acknowledge this target is unlikely to be met.

PPAs could help address the deficit. Individual projects in the pipeline cost billions of euros and securing finance remains one of the central bottlenecks.

Amazon's renewable energy portfolio

According to Amazon, the company operates around 900 data centres today with more in the pipeline. The firm is also the world's largest corporate buyer of renewable energy.

Amazon's portfolio includes more than 600 wind and solar farms capable of producing 40 GW of energy. In Ireland, the company has struck deals with green energy generators totalling 310 MW of capacity.

The company aims to secure agreements covering up to 800 MW. This is roughly the equivalent of two conventional power plants.

Amazon's partnerships include a deal with state company Bord na Móna to back development of the Derrinlough wind farm in County Offaly. Niamh said it will be capable of generating enough electricity to supply 90,000 homes.

She also pointed out that corporate deals fund renewable construction "on time, on budget and with no subsidies and at no cost to the taxpayer".

Contested grid consumption

Data centres remain a contested issue on the Irish grid. Energy consumption has attracted criticism from citizens and organisations alike, particularly as Ireland struggles with its own climate targets.

Niamh is looking to reframe the debate. She argues AI technology housed in data centres can actively reduce energy demand and carbon emissions elsewhere.

She cited a finding by Spanish energy company Iberdrola that Amazon's systems had helped it cut operating costs by between 10% and 30%. The savings were passed on to customers, according to the company.

It is the kind of argument Amazon will need to keep making. Niamh appears determined to take responsibility for that case.

"Ireland has the wind, the policy direction and the demand," she says. "Now it's about delivery."
