While the company proposes dealing with these costs in one case, Harris said he plans to ask the commission to deal with the matters separately.
"We're going to encourage the commission to implement the ENEC decrease and what happens with the merger and what happens with the asset transfer will be determined elsewhere," Harris said.
He said he planned to work with Consumer Advocate Division staff to file a formal response in the power companies' case.
"I think telling people the impact of the asset transfer on a standalone basis is more transparent," Harris said. "Right now they're trying to blend it in and basically say it all adds up to what we're paying today."
In testimony filed with the commission, Appalachian Power director of regulatory services Steven Ferguson said the companies' proposal is designed to provide stability for customers.
"This commission has historically worked with utilities to help keep customer rates stable by not lowering or raising them in a frequent and isolated fashion, but by making rate changes that take into account multiple issues and a long-term view," Ferguson said.
"The companies have a proposal that could provide their customers with a high degree of rate stability."
One potential future cost not included in the power companies' request is an increase in tree trimming and right-of-way maintenance costs expected later this year.
The PSC asked power companies to improve those programs in response to the power outages that followed last summer's derecho.
Power companies are expected to present new program plans - as well as any potential rate increases needed to cover their costs - to the commission this summer.
Appalachian, however, is not expected to file a rate case this year to recover damage costs from last year's major storms.
In a letter sent to customers Monday, APCo President Charles Patton said the company would not file for a rate increase this year to recover the $98 million in in-state damages suffered as a result of the derecho and Superstorm Sandy.
"While these expenses are legitimate costs of doing business, we do not expect to file an application with the Public Service Commission seeking rate recovery this year," Patton said.
