Examples relate to flexible datacenters or other power loads tolerant of intermittent operation and configured to use power received behind-the-meter. A system may include a set of computing systems powered by behind-the-meter power and a datacenter control system. The datacenter control system may be configured to monitor a set of conditions that includes behind-the-meter power availability at the set of computing systems and perform a weighted analysis using the set of monitored conditions. Based on the weighted analysis, the datacenter control system may be configured to modulate operating attributes of one or more computing systems of the set of computing systems. In some examples, the datacenter control system is a remote master control system in communication with a datacenter control system of a flexible datacenter housing the set of computing systems.
