I think power grids have a kind of similar problem, super oversimplifying here because this isn't my area: Baseload power plants (e.g. coal) are large and comparatively efficient, but they need to be kept running continuously, and they take a long time to restart. Other types of plants (e.g. natural gas) can start and stop more quickly to meet surges in demand, but they aren't as efficient overall. In order to keep the second type of plant available, but not constantly running, there's a whole separate contracts market for short-notice capacity. What could such a market look like for e.g. hospital equipment capacity contracts? Food growing capacity?
