A waiting list to buy power from competitors to Michigan's two dominant utilities is growing significantly.
A new report from state regulators shows Consumers Energy's queue of "choice" customers grew 57 percent in 2012. Detroit Edison's waiting list rose 74 percent.
The 10,000-plus customers on the waiting list can't buy electricity from alternative providers because of a 2008 Michigan law limiting competition to 10 percent of the market.
The report issued Friday will provide more fodder for opponents of the cap who want lawmakers to consider raising or eliminating it. House Republicans said last week they will look at the 10 percent cap and other regulatory issues, citing concerns about high electricity bills.
Supporters say the law is working as intended.
