Why do legislatures regulate competition for utility companies?

Legislatures regulate competition for utility companies to ensure fair pricing, reliability of services, and protection of consumer interests. Utility services, often considered essential, involve significant infrastructure and investment, making unregulated competition potentially harmful. Regulation aims to prevent monopolistic practices and ensure equitable access while balancing the need for innovation and efficiency in service delivery. Ultimately, these regulations seek to promote a stable and sustainable energy market that benefits both consumers and providers.
