The JL-26 enterprise license

Use the Joule Ledger commercially across your whole fleet, and publish results under it. $120,000 a year.

Reviewed 5 November 2026

What you get

  • Commercial use of the JL-26 method across your organization and fleet
  • The Energy Budget Toolkit, AAERL's software for setting energy spend policies so devices finish tasks within their reserve, on the scope your agreement sets
  • The right to publish audited results that cite JL-26
  • Notice of new editions and revisions before they apply
  • A named contact

Who it is for

AI providers, hardware makers, operators and device companies that report energy across many systems, or build the method into their own products.

How it works

  1. Send an enquiry with your fleet, use and publication plans.
  2. We send a written proposal with scope and terms.
  3. Sign the agreement; we set up your access.

Price and limit

  • $120,000 a year.
  • At most 300 a year. The limit reflects what we can deliver well; we do not run countdowns.
  • Prices rise 10% each year. A price you have paid stays fixed for the period you paid for; the increase applies from your next purchase or renewal, and we tell you before it does.

Renews yearly under a written agreement. We send a written reminder before each renewal deadline, by the method the agreement names, and you can choose not to renew.

What it is not

JL-26, the Joule Ledger, is a proprietary measurement method published by AAERL. It is not a consensus standard and has not been adopted by any standards body or regulator. An audit grade (Declared, Witnessed or Replicated) says who checked a result and how. It is not a certification, an accreditation or a regulatory approval.

Questions

Can we resell assessments under the license?

Only if your agreement says so. By default, the license covers your own systems and publications.
