I think crypto-mining could be help with bringing on more electricity from renewable resources online faster and more gracefully in the absence of sufficiently large scale grid batteries.

Imagine a solar or wind power plant that currently has sufficiently problematic swings in electricity production. A crypto-mining data center nearby could consume some if not all of this problematic excess electricity production more gracefully than disabling sections of the solar or wind power plant. In this application, crypto-mining would not be the primary reason to have all of this crypto-mining hardware. As the local grid requires more power generation, crypto-mining nodes could be turned offline to offset their electricity use.

This thought is just something I had, and there might be problems with it.
