Charleston, WV (AP) -- The West Virginia Public Service Commission's consumer advocate division doesn't like Appalachian Power's math behind its request for an 18.5 percent rate increase.
It says Appalachian Power improperly included roughly $6.9 million in maintenance and operation expenses.
Company spokeswoman Jeri Matheney said Appalachian Power based its estimates on the "latest and best information."
Appalachian Power will present its case Tuesday to the PSC.
The consumer advocate will be joined by several businesses across West Virginia in opposing the increase.
In addition to the increase the company wants to impose July 1, it is asking for a 14.5 percent and 13.2 percent over the next two years.
It says they're needed to cover higher coal and purchased power prices.
