The Story of Energy Deregulation in Maryland

Before the state legislature passed energy deregulation in Maryland, the state utilities were in charge of generating and delivering power to everyone. Because they had a monopoly on the supply, electricity rates in Maryland were sky-high.

This put a lot of pressure on residents and businesses alike. Because of this, state officials considered having their energy deregulated to allow better options for power.

In 1999, the Electric Customer Choice and Competition Act of 1999 was approved by the Maryland General Assembly, and this forever changed the utility industry in Maryland. Thanks to the Act, consumers can now purchase electricity through an electric retail supplier. Now, energy consumers in Maryland, both residential and commercial, may purchase electric power from one of several Energy Services Company (ESCO) providers.

An advantage of having energy deregulation in the state is that it helped reduce the power rates. Now everyone can choose a retailer with a plan that will match their needs and lifestyle.

Even if residents choose to get their supply from an electric retailer, the electricity will still come from one of the utilities in the state. But it will be much more affordable than getting it directly from the supplier.

What’s more, Maryland is looking to use alternative energy more in the coming years, which will help their residents and the environment.
