Our new online system TESSA (The Energy Security Safeguard Application) has replaced the ESS Registry, ESS Portal and ELT Portal. It will support the Energy Security Safeguard Schemes including the Energy Savings Scheme and Peak Demand Reduction Scheme (from commencement). Click the TESSA link to access TESSA.

TESSA has different functionality depending on what type of user you are and how you interact with the schemes.

User types

There are four main user types in TESSA:

  • Public Access Users – anyone can access the registers maintained in TESSA or ask a question
  • Sub account holders (Basic Users) – can raise cases in TESSA and enter data
  • Signatory Users (only available to Accredited Certificate Provider organisations) – can do what basic users do and submit applications for accreditation and applications to amend an accreditation
  • Primary User (Customer Admin Users) – can do what basic users do and create additional users in TESSA.
