The state Public Service Commission wants utility providers to explain how they responded to the June 29 derecho and how they plan to respond to future storms.
On Monday the commission requested state utilities attend a public meeting at 9:30 a.m. Oct. 22, to detail response efforts.
The meeting is part of an ongoing investigation into the utilities' response to the storm, which knocked out power to more than 500,000 statewide. Some customers remained without power for up to two weeks.
The power outages also led to water and phone outages in some areas.
The PSC began the investigation in late July by asking 11 utility companies to answer a series of questions about the storm response.
Utilities filed responses in August detailing the extent of the storm damage.
Appalachian Power and Mon Power reported a total of $172 million in damages following the storm. Frontier Communications estimated repairs to their system would cost $5.8 million; West Virginia American Water reported $750,000 in repair expenses.
While the companies reported the repair costs, the PSC said in its Monday order it would not consider any rate increase requests to cover those costs as part of the investigation in this case.
Any company wishing to cover those costs will have to file a separate case.
