Self-consumption means using electricity where it is generated instead of exporting all of it to the grid. In a local energy setup, this usually refers to matching on-site generation, such as solar or wind, with nearby demand and storage so more of the produced power is consumed immediately. Higher self-consumption can improve efficiency, reduce reliance on external supply, and make distributed energy projects more predictable.
In cyber security, self-consumption matters because it is part of the control logic for smart grids, microgrids, and industrial sites. Systems that balance generation, batteries, and loads depend on sensors, controllers, and communications that can be disrupted or manipulated. An attacker who interferes with load data, storage controls, or scheduling can reduce resilience or force inefficient grid export and import. Defenders therefore focus on segmentation, authenticated control channels, monitoring for abnormal demand patterns, and safe fallback modes when automation fails.
