Call it CrossFit for the digital age: a handful of data centers are trying out short bursts of load-shifting and operational flexibility to support the grid. But how do we go from a few reps to a lasting “grid fitness” movement? As regulators, utilities, and tech companies look to scale large-load flexibility into a widespread resource, the big questions are about how to design for flexibility, who pays, and how to distribute the full stack of benefits– like cost savings, speedier time-to-interconnection, increased resilience, and climate health. SEPA experts and friends dig into the policies, partnerships, and market designs needed to make data center load flexibility a new cornerstone of the clean energy transition.
