A large-load tariff is a utility pricing plan for customers with unusually high electricity demand, such as data centers, industrial sites, and large AI clusters. Instead of paying a simple retail rate, these customers may face separate charges for peak demand, grid upgrades, interconnection, and transmission costs. The goal is to make the electricity price reflect the strain that a very large consumer places on the power system.
In cyber security, large-load tariffs matter because availability depends on physical infrastructure. Attackers do not need to compromise a server to disrupt services if a site cannot secure power, cooling, or a viable contract to keep the facility operating. For defenders, the tariff is part of risk planning: it affects where systems can be deployed, how much redundancy is affordable, and whether a provider can sustain long-term capacity. Secure architecture now includes utility terms, not just network controls.
