The Global Leader in Certifying Clean Power
I-REC Services for Every Stakeholder
The Xpansiv I-REC Registry enables utilities, energy companies, and consumers to be certain of the nature and origin of the power they purchase. I-RECs also provide a valuable revenue stream for electricity generators, directly rewarding them for every unit of renewable energy produced. With 220 GW of generation already registered and growing, we are helping pave the way to a global clean economy.
Registrants (electric generation asset owners and their agents)
In order to produce I-RECs, production facility owners or entities acting on their behalf should onboard as a Registrant with the I-REC Issuer in their country. Becoming a Registrant enables the registration of production facilities with the Issuer and the submission of requests for I-RECs.
Participants (traders and other market players)
In order to trade or redeem (retire) I-RECs, traders, other market players, and End Users can become a Participant and hold accounts on the Xpansiv I-REC Registry. They can redeem certificates for their own reporting, or on behalf of their clients, and trade certificates with other Participants.
End Users (electricity consumers)
Any organization or individual can purchase I-RECs to advance their sustainability progress and secure documentation for emissions reporting. When redeemed (retired) by an End User, the I-REC is permanently and uniquely “consumed” by them and allocated for their reporting. An End User can choose to be a Participant themselves or contract with a Participant to manage this service on their behalf.
Issuers (organizations providing auditing, verification, and local support)
Xpansiv’s work is supported by a global network of Issuers, all accredited by the International Attribute Tracking Standard, who independently audit information and issue I-REC(E) certificates for electricity generated from sustainable sources. Every country in which I-RECs are issued has a single Issuer serving that region.
Governments (regulators, ministries, and others)
Xpansiv works with governments and policymakers to create robust, credible certification standards that encourage the transition to a certified, global clean economy. The International Attribute Tracking Standard has been designed to allow for interaction between both voluntary and compliance markets.

How It Works
The process is straightforward, efficient and trusted by power producers and certificate buyers worldwide.
Register Assets & Report Generation
Generators register and gain approval. They then report verified clean energy production on an ongoing basis.
Issue & Transfer RECs
Certificates are created and transferred through a secure, traceable ledger.
Redeem (Retire) for Claims
End Users (or Participants on their behalf) retire I-RECs to support clean energy procurement claims and sustainability reporting.

Frequently Asked Questions
Answers to common questions about the Xpansiv I-REC Registry
General
What is the difference between a Registrant and a Participant?
Registrants act on the producer side and can be the generator or an agent of the generator. A Registrant does not have to be the facility owner. However, Registrants must have the exclusive right to trade the renewable energy attributes. Registrants are the only parties that can register a production facility with the Issuer and request the issuance of I-REC(E)s.
Participants are market players and hold trade accounts on the registry. Participants can transfer I-REC(E)s to other Participants and redeem them on behalf of End Users. They can also transfer certificates from their account to the account of an approved Platform, such as a trading marketplace.
Can my organization be both a Registrant and a Participant?
Yes, an organization can register as both a Registrant and a Participant.
What supporting evidence do I need to submit with my application to become a Registrant or a Participant?
You need to submit the following information with your application:
- A completed, signed and dated copy of the Standard Terms and Conditions which will be sent to you for electronic signature. Please note that the Standard Terms and Conditions differ for Registrants and Participants. If your organization wishes to become both a Registrant and a Participant, we require completed, signed and dated copies of both.
- A completed, signed and dated copy of the I-REC(E)s Registry Application Form for Registrants and Participants.
- Copy of company accounts dated within the last 12 months (e.g. copies of the Profit & Loss Statement or Balance Sheet).
- For corporate bodies: proof of company registration number (e.g. a copy of the Certificate of Incorporation).
- For private individuals: a photocopy of the applicant’s passport.
For Registrant agreements, please contact the relevant Issuer. For all other documents and agreements, please see the Documents & Guides page.
Are the I-TRACK Standard Terms and Conditions negotiable?
No. The I-REC market operates on a non-discriminatory basis so that all Registrants and Participants trade on equal terms.
Are the Registrant and/or Participant Fees negotiable?
No. Market players require a robust energy attribute certificate (EAC) system that adheres to international best practices to enable them to make trustworthy energy claims. These instruments are provided by market facilitators, who are in return dependent on the use of these instruments to continue their facilitation of the market. The International Tracking Standard Foundation provides and requires a level playing field for all market players and guarantees a fair and competitive market. This means that all Participants and Registrants pay the same fees for the same services.
If I want to buy I-RECs, do I need to become a Participant?
No. You can use an I-REC(E) trader that is an existing Participant if you wish. Alternatively, you can become a Participant and buy directly from the market.
Facility (Power Generation) Registrations
How do I register a facility?
Please see the I-REC Registry User Guide for Registrants, which is available on the Documents & Guides page.
How long is my Production Facility registration valid for?
Production Facilities are registered for an initial period of 5 years. At the end of the 5-year period, your Issuer will contact you to provide you with the opportunity to renew the device for a further 5 years. Further details of the process and costs involved will be outlined in the fee structure, which is available on the Documents & Guides page.
If I want to register a wind farm, do I need to provide the coordinates of each wind turbine?
Yes. When registering a wind farm, we require a spreadsheet containing the coordinates for each turbine within the wind farm to be uploaded with the supporting documents.
Issue Requests
How do I submit an Issue Request to the I-REC Registry?
Full details of how to submit an Issue Request to the I-REC Registry are detailed in the I-REC Registry User Guide for Registrants, which is available on the Documents & Guides page.
When can I-REC(E)s be issued from for a newly registered Production Facility?
The first day of eligible production may be backdated to the Facility’s commissioning date. However, eligibility is limited by the applicable Residual Mix Deadline issuing period.
Can future I-REC(E)s be issued in advance of production?
No. An I-REC(E) is a statement of an historical fact and is issued against proof of generation from a specific source at a specific time. A future delivery cannot be guaranteed by any Issuer.
Do I have to claim for a full month’s production?
No. But please be aware that if you submit an Issue Request which is dated for a full month, but you only want to claim for half of the month, you will not be able to claim the balance at a later date. For example, if you had eligible production of 1000 MWh for 1 May – 31 May but you only wanted to claim 600 MWh, you could submit an issue request for 1 May to 19 May. You would then have the option to claim the remaining 400 MWh using the date range 20 May – 31 May.
How far back can I date an Issue Request?
Issue Requests for January-June must be submitted by 31 May the following year. Issue Requests for July-December must be submitted by 30 September the following year.
Can I request I-REC(E)s if I have the right to obtain emissions reductions or carbon credits?
It is not possible for you to retain the right to obtain emissions reduction certificates or carbon credits as well as claim I-REC(E)s for the energy nominated in an Issue Request. An I-REC(E) is a factual statement of an electricity production event. Such events may also contribute to a reduction in global emissions against a business-as-usual case. An I-REC(E) cannot be issued without inclusion of any avoided emissions, carbon credits, or similar market instrument that might be available to the registrant or device owner. When submitting an Issue Request for an I-REC(E), you must confirm that you hold the right to any such avoided emissions, carbon credits, or similar market instruments and that you irrevocably assign such rights within each issued I-REC(E). Each I-REC(E) will carry an identifier throughout its life that it includes the right to any such avoided emissions, carbon credits, or similar market instruments, which will be visible to I-REC(E) Participants.
Can I submit an Issue Request for a period that crosses a calendar year (e.g., from 31 December 2026 to 15 January 2027)?
No. It is not possible to submit Issue Requests that cross the end of a calendar year.
Can I submit an Issue Request for a fraction of a MWh (megawatt-hour)?
Yes. We support issuing, transfer, and redemption at the Wh (watt-hour) level. (A watt-hour is 0.000001 of a megawatt-hour). This means you can submit Issue Requests in increments of 0.000001 MWh.
Redemptions
How do I redeem (retire) I-REC(E)s?
Step-by-step instructions on how to redeem I-REC(E)s can be found in the I-REC Registry User Guide for Participants, which is available on the Documents & Guides page. Please note that the redemption of an I-REC(E) marks the end of its transferrable lifecycle. Once redeemed, an I-REC(E) can no longer be transferred. Therefore, please check the details carefully when making redemption requests, as the process is irreversible.
How do I request a redemption statement?
Step-by-step instructions on how to generate a redemption statement can be found in the I-REC Registry User Guide for Participants, which is available on the Documents & Guides page. Please note that once requested, it is not possible to reverse the process.
What dates can I use for the reporting period?
You may choose any reporting dates on a redemption statement. For example, it is possible to report from 1 December 2026 to 31 December 2027. However, it is up to the End User (beneficiary) and any organization to which they may report to determine which certificates may be acceptable for any given time period.
Can I amend a redemption statement once it has been requested?
No. It is not possible for Participants to reverse the process, so we recommend that you check the details at all stages of the process. The I-REC Registry also provides warning messages throughout the redemption process and allows users to preview the statement before completing the process. For example, you will see the following message at the approval stage:
Warning: This process cannot be undone so please check the details carefully before continuing.
Is it possible to amend the Beneficiary details?
No. Once created (i.e., by selecting ‘Submit’ on the ‘Add new Beneficiary’ screen of the I-REC Registry), it cannot be modified. If a Beneficiary is no longer required, it should be marked as inactive. Further details on how to add Beneficiaries or mark them as inactive can be found in the I-REC Registry User Guide for Participants, which is available on the Documents & Guides page.
When adding a new Beneficiary, do I add the country in the Location field on the I-REC Registry?
No. You do not need to add the country to the Location field, as the country should be selected from the ‘Country’ dropdown box. The Location field should contain the building number, street name, city/town or state, and the zip/postal code.
