NOTICE OF FILING, PUBLIC COMMENT HEARING, AND
EVIDENTIARY HEARING
On December 23, 2020, Appalachian Power Company (APCo) and Wheeling Power Company (WPCo) (collectively Companies) filed a duly verified Application for a Certificate to make internal modifications at coal-fired generating plants in Putnam, Mason, and Marshall Counties.
According to the Companies, the proposed modifications are necessary to comply with federal environmental regulations at the Companies’ Amos, Mountaineer, and Mitchell plants. The Amos plant is located approximately 15 miles northwest of Charleston, West Virginia, on the Kanawha River. The Mountaineer plant is located approximately 12 miles northeast of Point Pleasant, West Virginia, on the Ohio River. The Mitchell plant is located approximately 12 miles south of Moundsville, West Virginia, on the Ohio River.
The Companies provided construction estimates for several alternative projects. The estimate for APCo and WPCo construction costs necessary to allow all three plants to remain open until 2040 (Alternative 1) is approximately $317 million. The estimate for APCo and WPCo construction costs necessary to allow Amos and Mountaineer to remain open until 2040 and Mitchell to remain open until 2028 (Alternative 2) is approximately $286 million.
The construction will be phased-in over a four year period beginning in 2021. For Alternative 1 the Companies requested approval of the following surcharges in retail rates for the initial phase-in year from September 1, 2021 through August 31, 2022:

The Companies’ only resale customer in West Virginia is Black Diamond Power Company.
The average residential customer using 1,000 kWh per month would experience a rate increase of $.38 monthly or $4.57 yearly under the Companies’ proposal.
The proposed phase-one increases will produce approximately $4.8 million annually in additional revenue, an overall increase of 0.33%. If approved, the surcharge will increase gradually each year during the four year phase-in of the plant upgrades.
The project completion is expected to be achieved in 2025/2026. At that time, the Companies project that the capital costs for the Alternative 1 project will result in a total annual revenue requirement of $23.5 million. The projected surcharge rates upon substantial completion are projected to be as follows:
