The Michigan Public Service Commission has ordered two affiliated energy utilities, DTE Electric Company and DTE Gas Company, to provide evidence that they did not violate established and tariffed billing rules when they converted to a new billing system.

Finding that the underlying action was tantamount to unlawful retroactive rate making, the Ohio Supreme Court has sent back to the Ohio Public Utilities Commission a 2013 decision in which the commission had required FirstEnergy Corporation’s Ohio affiliates to return to their customers more than $43 million for what the commission deemed to be excessively priced purchases of renewable energy credits (RECs) dating back to 2010. In its decision, the commission said that an audit had revealed that some of the utilities’ REC purchases had not been prudent and therefore must be disallowed.

In a tentative decision, the Pennsylvania Public Utility Commission has disclosed how it intends to oversee future water, wastewater, and storm water services provided by entities created by Pennsylvania cities of the second class — specifically, the Pittsburgh Water and Sewer Authority (PWSA). The ruling proposes methods for rate making, tariff approval, compliance plans, infrastructure improvements, consumer protections, and other implementation issues. The commission asked that interested parties and stakeholders submit comments and input on the commission’s plans.
