How the schemes work for businesses

The Energy Savings Scheme (ESS) and Peak Demand Reduction Scheme (PDRS) provide financial incentives to implement projects that save energy and reduce electricity demand in peak times. These incentives are passed on to businesses by Accredited Certificate Providers (ACPs) in the form of discounts and other incentives. ACPs can create Energy Savings Certificates (ESCs) under the ESS for the energy savings or Peak Reduction Certificates (PRCs) for the capacity to reduce peak demand under the PDRS. Certificates can be sold to Scheme Participants (mainly retailers) to meet their obligations under the schemes. This creates a market for the certificates, which sets their value.

Information about eligible activities is available on the Activities for businesses page.

How to get involved

As a business, there are 3 ways to get involved:

  • work with an ACP to get incentives for energy savings or peak demand reduction projects
  • get accredited as an ACP by IPART and create your own certificates for:
    • energy savings projects under the ESS or
    • peak demand reduction projects under the PDRS
  • become an Auditor under the schemes.

Work with an existing ACP to get an incentive

Projects that may be marginal on a cost–benefit basis from energy savings alone may be feasible with the additional income from certificates.  An established ACP may be able to create certificates on your behalf. If you choose to go ahead with a project, you will be asked to assign the energy savings or peak demand reduction capacity from the project to the ACP by signing a nomination form so they can create certificates.

A list of ACPs that can help you implement projects is available on the List of ACPs for business page.

ESS ACPs that become accredited under the PDRS may be able to create PRCs for eligible activities implemented after 1 April 2022 if they meet certain criteria.

Get accredited as an ACP

To become an ACP in the schemes, you must apply to IPART. More information is available on the following pages:

Become an Auditor for the schemes

Auditors help ensure ACPs and Scheme Participants comply with the ESS and PDRS requirements and obligations. They are typically engaged directly by ACPs and Scheme Participants, however IPART can also engage auditors to audit ACPs and Scheme Participants.

Current members of the Audit Services Panel can complete audits under both the ESS and the PDRS. To become a member of the Audit Services Panel you must meet certain requirements. More information on how to become an Audit Services Panel member, including auditor requirements, is provided on our Join the audit panel page.
