Multiple Choice

The transmission system is interconnected and is referred to as the:

Electric power moves through a connected network of high‑voltage lines, substations, and interconnections that form a web across regions. This interconnected system is described as the transmission grid. The term highlights the lattice-like structure that enables power to be routed from generators to demand centers and to maintain reliability through multiple paths. While you’ll hear “power grid” used in everyday language, at the transmission level the precise label is the transmission grid. The distribution grid, by contrast, operates at lower voltages and serves end customers, so it isn’t the correct reference for the high‑voltage interconnection.
