The Renewable Electricity Register (RER) is a service for those accredited for the Renewables Obligation (RO), Renewable Energy Guarantees of Origin (REGO) and Feed-in Tariffs (large installations only, ROO-FIT) schemes.
The service facilitates the issue and redemption of the certificates used by these schemes. Registered account holders can use it to provide information, and undertake tasks required to support scheme activities.
The deadline for submitting 2025/26 generation data to Ofgem in order to claim REGOs for the Great Britain Fuel Mix Disclosure (FMD) is 1 July 2026.
Ofgem’s objective is to complete all application reviews and issue REGOs in advance of the FMD deadlines. However, this is contingent on several critical factors, including but not limited to:
1: The accuracy and completeness of your output data,
2: The timely submission of your applications, and
3: The quality and integrity of supporting evidence provided.
Failure to engage with Ofgem, or to supply requested evidence within required timescales may lead to instances where any REGOs associated with your accreditation may not be issued for the 2025/26 disclosure period, even where accreditation is ultimately granted.
Applicants are therefore strongly advised to prioritise engagement and ensure that submissions are accurate, complete, and supported by robust evidence.
RER Public reports are currently being uploaded to an external SharePoint site on Tuesday & Friday evenings, if you wish to access these reports please contact renewable.enquiry@ofgem.gov.uk who will provide instructions on this process.
The Renewable Electricity Register will currently be available Monday to Friday between the hours of 08:00 – 17:00 whilst we undertake maintenance outside of core hours. Apologies for the inconvenience.
Welcome to the Renewable Electricity Register (RER). This is the replacement for the Renewables & CHP Register and services the RO, REGO and ROOFIT schemes.
Please note the following important information regarding the RER:
• The RER user guide can be accessed via the link in the footers at the bottom of each page.
• Guidance documents for Generators, Agents, and Suppliers can be found on the Ofgem website, here:
o RO Guidance o REGO Guidance o ROOFIT Guidance
• Any ROC or REGO certificates which were not accepted by the receiver on the Renewables & CHP Register have reverted to the sender.
• If you have multiple generating stations within an organisation account, please be aware that the declarations have pagination, so when signing new or annual declarations these may be across more than one page.
• Due to the amount of data contained within, downloading the full Certificates (RO), Certificates (REGO) or Compliance Certificates reports can take 5-10 minutes. Please consider using the filters available to decrease the volume of data downloaded.
