RD247 - Appalachian Power®, A unit of American Electric Power, Integrated Resource Planning Report – May 1, 2018

Executive Summary:

This Integrated Resource Plan (IRP, Plan, or Report) is submitted by Appalachian Power Company (APCo or Company) based upon the best information available at the time of preparation. However, changes that afFect this Plan can occur without notice. Therefore, this Plan is not a commitment to specific resource additions or other courses of action, as the future is highly uncertain.

Much has changed since the Company filed its last Plan, including the following:

• the federal Tax Cut and Jobs Act of 2017 (2017 Tax Act) was signed into law;

• Virginia enacted legislation earlier this year that contained specific directions regarding various matters that are addressed in IRPs; and,

• on April 2, 2018, the Virginia State Corporation Commission (Commission or SCC) issued an Order denying APCo's request to acquire the Beech Ridge II and Hardin wind facilities (Wind Facilities)*1, on the grounds that those facilities are "not needed" by APCo to serve its Virginia customers.

The Commission's denial of APCo's request to acquire the Wind Facilities also raised concerns about the Company's forecasts of natural gas and energy prices, and called into question the constitutionality of some of the provisions of Virginia's newly-enacted legislation.

These events and others discussed throughout this Report, resulted in a number of differences between this Report and previous APCo IRP filings.
(*1) On page 6 of its Order Denying Reconsideration, the Commission stated as follows: "Because this proceeding is legislative in nature and our determination is without prejudice, APCo may present new evidence in support of a new application to acquire these resources, with the Grid Transformation and Security Act (the 2018 Virginia Act) applicable to such application filed on or after July 1, 2018." APCo is exploring its options in this regard, as the modeling performed for this IRP confirms that the opportunity to take advantage of the full 100% federal Production Tax Credit (PTC) available to the Wind Facilities is quickly slipping away.
