I love solar, but this "those who can afford microgrids can shield themselves from blackouts" paired with net metering where "the wealthy get paid a premium for excess generation and can buy expensive high-demand power back at a discount" probably aren't steps on the path to improved grid resiliency for any definition other than this weird "no island-wide outages" definition.
One alternative is decentralization, and the article talks about that:
> The town’s local environmental nonprofit Casa Pueblo teamed up with researchers from the U.S. Department of Energy’s Oak Ridge National Laboratory in Oak Ridge, Tenn., to develop a way to connect multiple microgrids to exchange power with one another, all without having to be hooked up to Puerto Rico’s grid. The strategy, called grid orchestration, ensures that if power is knocked out on one of the installations, the others aren’t compromised.
Is it the wealthy that are doing that? Maybe? Probably? But isn't that how any R&D technology investment starts?
It's also involving a government-funded lab to re-envision how these systems could work to achieve resiliency through coordinated decentralization. And if there's any truth to trickle-down economics, it would have to be in something that allows for a decentralized approach accessible to many, not a centralized approach that only rewards r > g accumulation. Sounds like a good use of government research funding to me.
