Through cables, power is transferred from the generator to a nearby transformer. Stepup transformer: While moving through wires, electricity loses part of its power; highvoltage electricity does so at a lower rate than lowvoltage energy. As a result, the voltage of the electricity is "stepped up" or "boosted" as it exits the power plant.
