In 2021, the Department for Energy and Mining (DEM) progressed a body of work to introduce local demand response (DR) capability requirements for a number of appliances in South Australia, including Electric Vehicles (EVs) and Air Conditioners (ACs).
To introduce these requirements, changes were made to the Electricity (General) Regulations 2012 to include regulation 58A (Designated electrical equipment must comply with demand response capability requirements).
In July 2021, DEM contracted George Wilkenfeld and Associates with Auseng Pty Ltd to evaluate international standards for EV chargers that provide equivalent DR capabilities to AS/NZS 4755, and to provide a report (PDF, 1.8 MB) on their findings.
The report recommends that the Technical Regulator Guideline should require EV Supply Equipment (EVSEs) meet either of the following standards: OCPP1.6 V2 or ANSI/CTA 2045-B. These standards were found to be the most suitable for immediate adoption based on an evaluation against a range of criteria, including maturity, market adoption and equivalence to the DR capability within the AS/NZS 4755 framework. The standards are also open and non-proprietary.
The consultant’s evaluation found that 30 of 47 EVSE models investigated would currently meet OCPP1.6 V2 or ANSI/CTA 2045-B.
With such a high level of existing complying models already in the market, the Technical Regulator Guideline - Technical Standard for Installation of EVSE’s (PDF, 672.3 KB) will commence on 1 July 2024.
The Technical Regulator Guideline also includes a ‘deemed to comply’ option for EVSEs that do not meet OCPP1.6 V2 or ANSI/CTA 2045-B. This option will enable suppliers to demonstrate to the Technical Regulator that the EVSE has been tested and meets a set of DR criteria.
