The electric grid connects electricity generation with homes and businesses. Understanding its main parts helps distinguish a utility outage from an issue within your property’s electrical system.
Generation, transmission and distribution
Electricity is produced from several energy sources. Transmission lines carry power over long distances; substations and transformers adjust voltage, and distribution networks deliver it to local customers. Grid operators coordinate supply and demand as conditions change.
Higher transmission voltages help reduce losses over distance. Power still passes through several stages before reaching a home’s service equipment and branch circuits. The U.S. Energy Information Administration explains this delivery system in more detail.
What to do during an outage
Use your utility’s official outage information and reporting channels. Stay away from downed wires and damaged utility equipment. If only part of your property is affected, an electrician can help assess an internal problem; do not open the panel to investigate.
Prepare backup lighting and power
Keep flashlights available instead of relying on candles. Portable generators must operate outdoors at least 20 feet from a home, with exhaust directed away from buildings; never use one in a garage. Follow manufacturer instructions and have an electrician plan any connection to building wiring.
Read the CPSC’s outage safety guidance. Bianco Electric can discuss generator installations and electrical diagnosis for your property.
