The electricity market is divided in two portions the lines and meters aka delivery and supply which is the amount of power you use in kilowatt-hours or kwh.
The power plants that generate the power to the grid up until deregulation had one customer the local utility. The local utility would then turn around and sell back the power to the end-user the customer which was a prime example of the board game Monopoly.
The Electricity Market is separated into delivery provided by the local utility/supply, which can be provided by competitive suppliers.
Residential and business customers now have the ability to choose their energy supplier and pay lower rates than the utility charges , while the utility will continue to deliver the power, repair any service problems and consolidate our charge on their bill for your convenience!
Now the customer has more options to purchase power at a cheaper rate and save money!
