I forgot to mention that you only need to set up for very small-scale production, almost maker-scale, so not a whole lot of land is required. With automation, any outage will create a steady trickle of usable goods. The DC's I work with run generators once a month to test (and generally, most engines don't like sitting still all the time). Certainly sufficient for use by nearby residents, so co-generation would benefit third parties if not the DC itself.
