Why Retail Energy is Not Truly Pass-Through Wholesale: Unlocking Enterprise Savings with ISO Direct

For many enterprise energy buyers, signing a retail electricity contract every one to three years has become the default approach. It feels easy, predictable, and familiar. But here’s the hard truth: retail energy does not pass through true wholesale.

Whether you’re a data center operator in PJM, a hospital network in NE-ISO or a REIT portfolio in the NYISO, every retail supplier and utility ultimately sources from the same place—the wholesale market run by the Independent System Operator (ISO). The difference is in what you pay. And if you’re buying retail, you’re paying too much.

The Hidden Costs of Retail Energy

Retail suppliers market themselves as facilitators, but what are they really facilitating? The list of markups is long:

  • Hidden margins built into “fixed price” products
  • Risk premiums to protect the supplier’s bottom line
  • Broker fees layered into your contract

The result? Enterprises overpay for energy year after year, often without realizing it.

Why ISO Direct is Different

ISO direct procurement eliminates the middleman. Instead of buying power through a retail supplier, enterprises purchase directly from the same wholesale ISO market used by suppliers and utilities.

This approach is not about speculation or added risk. It’s about control and transparency.

  • Retail = highest costs, least transparency
  • Utility = moderate value, limited visibility
  • ISO Direct = maximum savings and full transparency

At ECM, we’ve proven that enterprises can achieve 5%–25% cost reductions without taking speculative positions—just smart, managed market access.

The Executive Impact

For enterprises with large loads, the numbers are transformative:

  • Data centers: Seven-figure savings are common in year one; for hyperscale facilities, savings can scale into tens of millions or even hundred+ million.
  • Hospitals and healthcare systems: Lower energy costs free capital for patient care and facility investments.
  • Financial institutions and REITs: Cost transparency supports ESG mandates and boosts investor confidence.

In short, ISO direct turns energy procurement into a strategic advantage, not just a line item on the budget.

Key Takeaways from Ask the ISO Expert: Episode 3

  • Retail does not equal wholesale: Retail contracts are built on the same ISO wholesale market but add costly layers of fees, margins, and premiums.
  • ISO direct delivers transparency and savings: Buying energy from the same place that suppliers do but being able to maximize visibility and control by going direct.
  • Savings at scale are significant: ECM clients achieve 5%–25% reductions, with many realizing seven-figure savings in the first year.
  • Enterprise scale magnifies opportunity: For hospitals, REITs, financial institutions, and data centers, ISO direct translates into multi-million-dollar advantages.
  • With ECM, results are proven: 20+ years in NYISO, PJM, and NE-ISO markets with a 100% client success record.
