W5: Distribution-Connected Data Centers

Workstream 5 (WS5) focuses on understanding and enabling distribution‑connected data centers (DxDCs) as a class of loads with distinct technical, operational, and planning considerations compared to transmission‑connected facilities. The work develops a comprehensive characterization of DxDC architectures and workloads, evaluates their flexibility potential and grid‑support capabilities, and examines the operational, interconnection, economic, and reliability frameworks needed to integrate these resources at the distribution level. Through coordinated analysis, stakeholder engagement, and the development of practical frameworks and playbooks, WS5 aims to reduce uncertainty, support streamlined interconnection and planning processes, and provide actionable guidance, tools, frameworks, technical specifications, etc. for utilities, data center developers, and and other stakeholders to implement. Integration with other workstreams ensures alignment with broader flexibility, market, and system‑planning efforts while supporting informed decision‑making as distribution‑connected computing continues to evolve.
