Harley Henninger

Harley Henninger is a Senior Staff Electrical Engineer at Diamondback Energy with 22 years of experience spanning the refining, chemicals, and upstream oil and gas industries. His career has focused on the planning, design, and reliability of electrical power systems supporting large‑scale industrial and upstream operations, with extensive experience across the Permian Basin.

In addition to his engineering role, Harley serves as Vice‑Chair of the Permian Basin Petroleum Association (PBPA) Electrical Coalition, where he engages with transmission service providers (TSPs), ERCOT, and the Public Utility Commission of Texas (PUC) on policy, planning, and operational issues affecting electric reliability in Far West Texas. He provides technical input and operational perspective on Permian Basin concerns related to Generic Transmission Constraints (GTCs) and Interconnection Reliability Operating Limits (IROLs), particularly as these measures impact critical upstream loads, production continuity, and regional grid stability.

Harley contributes to coalition positions and industry feedback associated with PUC transmission and Certificate of Convenience and Necessity (CCN) proceedings, ERCOT planning discussions, and stakeholder engagements focused on load growth, transmission timing, and reliability risk. His work emphasizes practical, field‑informed perspectives that help bridge regulatory objectives with real‑world operational realities facing upstream operators.
