CEO Bill Fehrman (appointed late 2024, succeeding Julie Sloat) leads AEP's $54 billion five-year capital plan (2025-2029) — one of the largest capital programs in US utility history — focused on transmission expansion (building 765kV and 345kV high-voltage transmission lines to interconnect renewable generation and serve data center load growth), distribution system modernization, and regulated renewable generation additions that earn AEP's allowed return on equity across 11 state regulatory jurisdictions.
