Grid readiness is the ability of an electricity network to carry, balance, and deliver power reliably for a new asset. It includes enough transmission capacity, stable frequency and voltage control, safe interconnections, and operational procedures that let the new load or generator fit without stressing the system. In plain terms, a project is not truly deployable until the grid can absorb it safely and consistently.
In cyber security, grid readiness matters because power systems are high-value targets and failures can cascade quickly. Weak readiness can expose poor segmentation between operational technology and corporate networks, missing telemetry, brittle control logic, or inadequate backup paths. Attackers may try to exploit these gaps to disrupt load balancing, overload substations, or force unsafe shutdowns. Defenders use readiness assessments, monitoring, redundancy, and tested recovery plans to make sure the network can keep operating even under attack or during equipment failure.
