What is the role of transformers within the electrical grid?

Transformers play a crucial role in the electrical grid by altering voltage levels to ensure efficient transmission and distribution of electricity. When electricity is generated, it typically has to travel long distances to reach consumers. By using transformers, the voltage can be stepped up (increased) for transmission over long distances, which minimizes energy losses due to resistance in the wires. Once the electricity reaches its destination, transformers can then step down (decrease) the voltage to safe levels suitable for use in homes and businesses. This process is fundamental for maintaining the efficiency of the electrical grid and ensuring that power is delivered safely and effectively to end-users.

Other options describe functions that are not directly tied to the primary role of transformers within the grid. For example, generating electricity from renewable sources involves different technologies like solar panels or wind turbines, energy storage focuses on battery systems, and load management typically involves demand response strategies but does not involve voltage transformation directly.
