SK Telecom has expanded its partnership with Schneider Electric to develop an AI Data Centre (AIDC) in Ulsan.

Under the deal, Schneider Electric will supply mechanical, electrical and plumbing equipment, such as switchgear, transformers, automated control systems and Uninterruptible Power Supply units.

The agreement builds on a partnership announced at Mobile World Congress 2025 and includes using Schneider's Electrical Transient Analyser Program within SK Telecom's data centre management system.

It will allow operations to be optimised through a digital twin model instead of relying only on traditional monitoring tools.

Both companies have also agreed on prefabricated solutions to shorten construction times, reference designs for new facilities, and joint efforts to grow the Energy-as-a-Service business.

A Memorandum of Understanding extends the partnership to other SK Group affiliates, combining battery technologies with Uninterruptible Power Supply and Energy Storage Systems.

Executives said the collaboration would help set new standards for AI data centres and create synergies across the SK Group. It is also expected to support SK Telecom's broader AI strategy while contributing to sustainable and efficient infrastructure development.
