What role does a distribution network play in electricity delivery?

The distribution network plays a crucial role in electricity delivery by incorporating substations and service lines that facilitate the transport of electrical energy from the high-voltage transmission system directly to end-users, such as homes and businesses. This network is responsible for stepping down voltage levels from transmission lines to a manageable level for consumer use, ensuring that electricity is delivered safely and reliably. The distribution network also includes transformers that adjust voltage levels appropriately, along with the necessary infrastructure needed to distribute power effectively within a region.

While moderating voltage levels, connecting generation facilities to the grid, and regulating tariffs are important aspects of electricity delivery, they pertain more to other elements of the energy system rather than the explicit function of the distribution network. Thus, understanding the composition of the distribution network, including its role in providing the final link between power generation and consumers, underscores why the inclusion of substations and service lines defines its function in electricity delivery.
