A regional government is deciding how to build out its electricity infrastructure to serve a large, populated area. The primary goal is to achieve the lowest possible average cost per unit of electricity delivered to consumers. Two plans are proposed:

Plan A: Construct one single, large, interconnected grid to serve the entire region. Plan B: Construct several smaller, independent grids, each serving a different district within the region.

Which plan is more likely to achieve the goal of lower average costs, and what is the economic reasoning?

Cost Structure and Economies of Scale in Power Grids

An electricity provider invests heavily in building a new, extensive network of transmission lines and pylons to serve a growing city. Once this infrastructure is in place, the cost of transmitting each additional kilowatt-hour of electricity is very small. Which of the following statements best analyzes the relationship between the provider's cost structure and the quantity of electricity it delivers?

If an electricity grid operator doubles the amount of electricity it transmits through its existing network, its average cost per unit of electricity delivered will likely increase.

Match each economic term to its correct description within the context of operating an electricity grid.

Because the initial investment in building an electricity grid is very high while the cost to transmit each additional unit of power is low, the average cost per unit of electricity falls as the total amount of power transmitted increases. This economic principle is known as ____.
