Siemens has partnered with renewable energy player CES Energy to provide on-site electrical power services for tech multinationals locating their data centres in Ireland.

While Ireland, with its cool climate, is deemed a good choice for these centres, the government is conscious that the pace of development is overtaking the already ambitious grid development plans in Ireland, and could hinder Irish potential in this area.

According to Gary O’Callaghan, chief executive of Siemens in Ireland, on-site generation has many benefits for data centre operators, offering a reliable power supply to to meet data centre timeframes, as well as the reduction of costs and carbon footprint.

“The changing energy landscape is providing new opportunities for the data centre sector,” O’Callaghan explained.

“With the joint expertise of Siemens and CES Energy, tech companies now have the option of self-sufficiency in power generation. When you make and manage your own energy, costs are predictable, you have a direct impact on your sustainability and you’re not constrained by grid availability.”

Additionally, combining heat recovery with renewable options such as solar or biogas ensures that on-site generation assists the country in reaching its emissions targets while providing a key sector in Ireland with the critical energy it needs.

On-site generation also offers the opportunity to channel excess heat and power into local Irish communities to power homes and businesses, an energy-efficient practice adopted by Scandinavian countries.

In this way, a data centre with 10 MW capacity can heat around 20,000 modern residential apartments.

“On-site generation is key to meeting the future energy demands of these power-hungry data hubs, while delivering on Ireland’s carbon footprint commitments,” explained Brendan Marren, director of CES Energy.
