Texas deregulated most of the state's electricity markets in 2002, a move aimed at lowering electricity costs by letting consumers choose their own electric power providers and their own plans. Some parts of Texas continued to be regulated, including those that get power from municipal utilities, electric cooperatives and investor-owned utilities that operate outside the state's primary power grid.
The takeaway here is simple. As is the case in Washington and Iceland, if a state or country has an abundance of natural resources, it should take advantage of them to drive down the price of a kWh to attract businesses. Diversification is especially essential where possible. Without businesses and industries paying to draw power from the electrical grid, the local economy stagnates.
As of April 2014, 16 U.S. states and the District of Columbia have deregulated electricity markets. Along with aforementioned Maryland and Texas, electricity deregulation is current in Connecticut, Delaware, Illinois, Maine, Massachusetts, Michigan, Montana, New Hampshire, New Jersey, New York, Ohio, Oregon, Pennsylvania, and Rhode Island. Seven additional U.S. states began the process of electricity deregulation but have suspended efforts: Arizona, Arkansas, California, Nevada, New Mexico, Virginia, and Wyoming.
