Examining the Effects of Deregulation on Retail Electricity Prices
Taber, John T.; Chapman, Duane; Mount, Timothy D.
A primary aim of deregulation is to reduce the customer cost of electricity. In this paper, we examine the degree of success in reaching that goal using a variety of methods. We examine rates for each of four customer classes; for regulated, deregulated and publicly owned utilities; and for three definitions of deregulation. We control for a variety of factors which may independently affect differences in electricity price: climate, fuel costs, and electricity generation by energy source. Taken as a whole, the results from our analysis do not support a conclusion that deregulation has led to lower electricity rates.
