To prohibit the Public Service Commission from altering the special "economic development" rates granted by a utility to a particular company. In particular, the bill insulates the special rates granted by Consumers Energy to the Hemlock Semiconductor subsidiary of Dow Corning from a ban on cross-subsidization between residential and commercial/industrial customers; in effect it would cause residential and other business customers to subsidize Hemlock's below-cost rates. This ban on cross-subsidization ("deskewing") was part of a 2008 bill that mostly ended the ability of non-residential customers to buy power from a generator other than Detroit Edison or Consumers Power, essentially restoring their monopoly status. See also 2008 bills that granted millions in tax breaks and subsidies to Hemlock.
