Harper Advisory LLC

What Harper Advisory LLC does

Harper Advisory LLC is a boutique energy regulatory and commercial advisory firm founded in 2022 by Sam Harper and headquartered in Shenandoah (Spring), Texas. The firm serves large industrial electricity consumers — including steel mills, refineries, petrochemical operators, manufacturers, and data centers — across U.S. organized wholesale electricity markets (ERCOT, CAISO, PJM, MISO, IESO) and the Mexican wholesale market (CENACE). The practice is organized around three service lines: regulatory advocacy before the CPUC, PUCT, CARB, ERCOT, and adjacent agencies; commercial advisory spanning procurement, hedging, and contract structuring with quantitative analysis built on first-party interval data; and renewables and storage advisory for onsite and grid-scale resource integration.

The business model is fee-based professional services with negotiated engagement terms, and the firm is privately held without external funding. The team is small — approximately seven named individuals drawn from operators including ArcelorMittal and Gerdau — and includes the principal, data scientists, policy analysts, and consultants. Marquee engagements include ongoing representation of the California Large Energy Consumers Association (CLECA, 500+ MW aggregate load) and the ERCOT Steel Mills coalition, participation in PG&E's 2027 General Rate Case, a seven-organization joint intervention in Southern California Edison's 2025 GRC, and the PUCT Project 58481 outcome that raised the large-load threshold from 25 MW to 75 MW. The firm's public regulatory filings, testimony, and participation in technical conferences serve as both work product and demand-generation infrastructure.
