W. Va. Code § 8-19-2b: Right of appeal by customers.

Customers may appeal a rate increase to the circuit court of the county in which the municipality is located on the grounds that the rate ordinance or its passage does not comply with the provisions of this article by filing a petition, signed by at least 750 customers or 25 percent of the customers served by the municipal electric utility, whichever is fewer. Any petition challenging the ordinance must be filed within 30 days following the adoption of the rate ordinance.
