Where Your Energy Comes From

The electric grid is the interconnected network that makes electricity accessible wherever we need it. It’s a sophisticated system with three core components:

• Generation: Making the Electricity
  Power plants and renewable energy facilities convert energy from various sources into electrical power. Large quantities are generated and fed into the grid.
• Transmission: Moving Electricity
  High-voltage power lines are responsible for efficiently transporting the electricity over long distances from the generation sites to local areas. These lines are often supported by large metal towers.
• Distribution: Delivering Electricity
  This final stage involves delivering electricity at a lower, safer voltage to individual consumers. Substations reduce the voltage from transmission lines, and local power lines to safely carry it to homes, businesses, and neighborhoods.

High energy demand periods, like hot summer days when air conditioners surge, strain the grid, potentially causing overloads and blackouts. This increased workload accelerates equipment wear and tear, leading to more frequent maintenance and potentially higher electricity costs, often with greater environmental impact.

The grid can also experience disruptions due to storms, accidents, or equipment failures. Grid operators prioritize restoring service as safely and quickly as possible.
