Implementation data upload

To upload implementation data you need to:

  1. Save your implementation data in csv file format (use the ESS Example template or PDRS Example template to capture data in the right format before saving as a csv file). You can only include implementations from one Accreditation (e.g. GHGR12345A) and one base vintage (e.g. 2024) in each csv file.
     
  2. Complete the registering certificates case in TESSA where you will be asked to upload your csv data file.

The CSV Specification Guide and Examples Templates detail the implementation data you need to provide and how to format your data for uploading in TESSA. You must use these latest CSV Specification and examples templates from 1 July 2025:

Note the CSV specification is not intended to satisfy all ACP regulatory requirements. Acceptance of your data by TESSA is not confirmation that you have met all your obligations. It is your responsibility to ensure that you understand and comply with your obligations, including holding all necessary evidence that implementations meet requirements.
