Energy surges are caused by significant load increases. Power surges happen when there is a massive spike in your electrical system's current. They only last about a fraction of a second but can cause lifelong damages to any outlets or plugged-in appliances and can even blow out a PG&E transformer and/or damage infrastructure. This is due to the power surge overloading the circuits connected to your electrical system. This occurs when a customer increases their electric usage significantly. This increase in electric consumption is much higher than what PG&E factored into the transformer size for the neighborhood. Some examples of load increases include home Improvements such as additions, lighting upgrades, electric car, large electrical appliances, and more.
