Why does meralco of the Philippines is one example of pure monopoly?

Meralco, or the Manila Electric Company, is considered a pure monopoly in the Philippines because it is the sole provider of electricity in its service area, which covers Metro Manila and surrounding regions. This means there are no direct competitors in the market, allowing Meralco to control pricing and supply without the pressure of competition. Additionally, the high barriers to entry, such as substantial infrastructure costs and regulatory requirements, further reinforce its monopolistic position. As a result, consumers have no alternative electricity suppliers, making Meralco a classic example of a pure monopoly.
