As always, great piece, Lyn. Like many others, I am very interested in the idea of data centers as “flexible assets.” But I do wonder whether there is some hype, or at least very high expectations, about how flexible data centers can actually be/are willing to be in ways that maintain/enhance grid reliability.
Your post made me think of a LinkedIn post by Margarita Patria (https://www.linkedin.com/feed/update/urn:li:activity:7403784074554716160/) on how utilities view data center flexibility. The bottom line was: "data center flexibility is limited and can’t be relied on for resource adequacy planning or reliability. "
Nobody expects perfect flexibility from DCs (what would perfect even be? The layered system is complex!) as flexibility depends on a host of DC-specific features (workload, location, incentives, ...) and, as a whole system, on layers. But I wonder whether we may be giving DCs too much credit for their willingness to be flexible. Will planners and operators be able to reliably count on/enforce this flexibility?
When I think about the “five nines” reliability expectations that data-center founders/CEOs love to emphasize, alongside the pacing problem of a twentieth-century grid trying to adapt to twenty-first-century players, it feels like there is still a missing institutional piece. Or, to put it as a question, can we expect those layers to align to the point where this flexibility from data centers can be extracted to enhance system-wide reliability? The technical DC capability to be flexible may be there, but can it be converted into **dependable** system value? I
I think we need to build the institutional architecture so that we start to treat this as a contracting problem, where the grid operator and the data center contract over a specific set of behaviors, actions, payments, and penalties. Then we can count it for RA.
