Public utilities: electric utilities; cap on electric choice; modify. Amends sec. 10a of 1939 PA 3 (MCL 460.10a).

This bill establishes a 10% cap on the portion of an electric utility's retail sales that can be served by alternative electric suppliers, meaning no more than 10% of a utility's customers may switch to alternative providers at any time. The cap can be adjusted downward if less than 10% of sales are already with alternatives, but must return to 10% after five years without adjustment. Exceptions allow specific customers - like those with facilities continuously served by alternatives since 2008 or Upper Peninsula iron ore facilities under settlement agreements - to exceed the cap for their operations. The bill also maintains a queue for customers waiting to switch to alternatives as of December 2015, requiring utilities to manage these requests annually. These changes directly affect Michigan electric utilities, their retail customers, and alternative energy providers seeking to serve them.
