What Is A Utility Company?
Natural gas and electric utility companies were the main source of energy for many years. In fact, since the original organization of energy in the United States, utilities were responsible building power and gas lines, generating power, delivering electricity and natural gas, and billing customers. In states that are still regulated today, utility companies are still responsible for all of this.
In a deregulated state, however, utility companies have a slightly different role. Read more about the difference between energy suppliers and utilities in deregulated states below.
How Do Utilities Differ From Energy Suppliers?
In states that have deregulated utilities, utility companies play a different role. In these states, utilities do not own the entire energy supply chain. In fact, deregulation makes it impossible for utilities to own generation plants, and even sell energy to end users in states like Texas.
In these states, energy suppliers are allowed to purchase electricity and natural gas from the wholesale market and resell it to the utility company’s customers. Some energy suppliers even generate their own electricity and natural gas in these states. When a customer elects to purchase energy from a supplier, the utility company still maintains local power lines, delivers energy to the customer, and in many cases, is still in charge of billing the customer.
