Natural Causes

The most common cause of power cuts are natural. Weather can cause dramatic and powerful circumstances that can can cut off power to individuals, communities or in worst the case, an entire grid network.

Lightning is the most common cause of the power cuts. When lightning strikes a building, it creates a power surge through existing electrical circuits. Ideally all electrical items should be unplugged in a lightning storm, to stop them from being damages by power surges. Snow and rain can cause accidents that also damage power infrastructure. High winds and extremely icy conditions can damage power lines and poles. Even extreme heat can warp metal, potential cause power cuts in extreme cases. Humidity and dust build up can also be an issue, as they can cause short circuits in equipment.

The Grid

After natural causes, it is likely that power cuts and surges will come from the electrical grid itself.

Other power supply problems stem from issues with the grid itself. Anything from scheduled maintenance to a fault component could cause the grid issues. If this happens the power surges could damage sensitive equipment.
