In a market limited in size, potential new competitors have little incentive to enter because doing so would lower the industry’s returns below the cost of capital.
Example: Union Pacific Corp.
Dominion Energy Inc is an integrated energy company. Its activities include electric generation, natural gas transmission, storage, distribution and gathering pipelines, and electric transmission and distribution lines. Morningstar states that Dominion’s Atlantic Coast Pipeline “is an excellent example of the dynamics of the efficient scale moat source” because “once a pipeline is constructed, there is little incentive for competitors to enter a market.”
