Power demand from data centers is clearly increasing faster than current electric infrastructure and markets can accommodate. Therefore, data centers and grid operators are exploring one workaround: flexing data center loads during peak demand times. Brian Janous, of Cloverleaf Infrastructure, and Chris Pennington, of Iron Mountain Data Centers, discuss the current opportunities and challenges to data center flexibility. For example, there are options for moving workloads among facilities and leveraging the improving capabilities of battery storage. On the other hand, demand response is not a major business driver. The industry needs to define relatively simple solutions that can be deployed at scale to meet market demand.
