The gas supply shock absorber also comprises pressure sensing and regulating valves, which direct positive pressure spikes to the gas storage and draw gas from storage during negative pressure spikes.

If the gas storage has sufficient gas, a co-located data center utilizes such gas for increased electrical power generation during increased processing activity, which can be requested or generated. Conversely, if the gas storage has insufficient gas, and a negative pressure spike occurs, the data center throttles down or offloads processing.
