Harper Advisory advises large industrial energy consumers across the US on regulatory proceedings, energy procurement, commercial strategy, and renewable energy — with particular focus on organized wholesale markets including ERCOT, CAISO, and PJM.

Large industrial end users — companies for whom energy is a significant cost of production — bring distinct commercial pressures, operating constraints, and regulatory exposure to every engagement. Harper Advisory was purpose-built for that client, by people who have managed energy at that scale.

Regulatory — Representation and advocacy in state utility commission proceedings, ISO/RTO stakeholder processes, and state agency rulemakings. Expert witness testimony, formal comments, and policy engagement with commissioners and staff before CPUC, PUCT, CARB, and other agencies.

Commercial — Energy market strategy, commodity risk management, energy contract negotiations, demand response program participation, and support for new and expanded load interconnections with utilities and ISOs.

Renewables & Storage — Renewable energy and battery storage advisory from feasibility through execution: Private-Use-Network configuration, behind-the-meter BESS analysis, RFP management, developer proposal assessment, and RPS compliance strategy.

Principal Sam Harper spent fifteen years managing energy at scale for major North American steel producers — first at ArcelorMittal, then as Director of Energy at Gerdau. He served on the ERCOT Board of Directors from 2016 to 2021. Harper Advisory's team includes energy consultants, data scientists, and analysts with deep experience across PJM, ERCOT, CAISO, IESO, MISO, and unorganized markets.
