As data center demand grows and infrastructure constraints increase, flexibility in design is essential to building a reliable and resilient system. EPRI’s Data Center Flexibility (DCFlex) Initiative is pioneering effort to demonstrate how data centers can play a vital role in supporting and stabilizing the electric grid while enhancing interconnection efficiency. It aims to drive a cultural, taxonomic, and operational transformation across the data center ecosystem, offering a comprehensive blueprint for stakeholders including utilities, market operators, technology innovators, and policymakers. This panel introduces a recent demonstration project on data center flexibility completed in Arizona as a part of DCFlex.
