The PDRS, which was launched in 2022 and managed by NSW Independent Pricing and Regulatory Tribunal (IPART), is a part of an overall strategy to improve energy security and alleviate pressure on the electricity network. The scheme operates on the principle of paying Peak Reduction Certificates (PRCs) to businesses and consumers for installing energy-saving devices that lower peak levels of electricity usage. PRCs are tradable commodities in a regulated market. Battery installations to specific standards create PRCs, which may be sold to accredited certificate providers (ACPs). This provides an economic incentive for battery installers and consumers to participate in the program. But why do such certificates have value, and how do installers maximize their value?

Economic Value of PRCs for Battery Installations

One of the primary advantages of the PDRS is that it can award Peak Reduction Certificates. The quantity of PRCs that are released is based on certain parameters such as available capacity of the battery and peak demand reduction efficiency. For example, a 14.2 kWh battery can lead to approximately 1,133 PRCs, which could be equivalent to significant economic savings. Demand and supply determine the price of PRCs in an open market. Battery installers can advise their customers on how they can achieve maximum returns by making the most suitable storage facility decision. ACP-holding installers also have the ability to de-mystify certificate trading, offering customers maximum financial return. What is the role of battery installers in assisting their customers in selecting the optimal system in a bid to maximize their returns?

Eligibility Requirements for Battery Installers

To qualify for inclusion in the PDRS, battery installers and the batteries themselves must fulfill certain requirements of eligibility.

Approved batteries must possess a usable capacity of 2 kWh to 28 kWh. They must also be on the Clean Energy Council’s (CEC) approved products list. The battery system has to be installed on a site of an existing solar photovoltaic (PV) system or as part of a new installation of a solar PV system. There should be a minimum warranty of 10 years, along with a condition that the battery should have at least 70% usable capacity during the warranty period. Under these conditions, battery installations are eligible for PRCs under the PDRS. Installers are also required to follow strict documentation procedures in order to achieve compliance. What does a battery that is not complying with these terms do, then?

Accreditation and Compliance for Installers

Installers seeking to take advantage of the PDRS need to become accredited.

The major accreditation needed is the Grid-Connected Battery Storage “Design and Install” or “Install Only” accreditation with Solar Accreditation Australia. Compliance is an integral part of the scheme. Installers are required to give complete records, such as pre-installation and post-installation photographs, signed customer statements, and technical details of the installed battery system. Misprocedure can result in rejection of PRC claims, hence the installers’ requirement of keeping proper records. But how do installers ensure an easy accreditation process?

Working with Accredited Certificate Providers (ACPs)

In order to gain most from the PDRS, battery installers can collaborate with Accredited Certificate Providers.

Accredited Certificate Providers are institutions that are known to produce and exchange PRCs on behalf of consumers and institutions. If they work with ACPs, then the installer can make the transactional process for customers easier so that customers will enjoy their economic gains without entering into certificate trading. ACPs play an important role in accumulating PRCs to sell on the certificate market, making it easier for schemes to comply, and enabling trading by battery owners. IPART publishes a list of approved ACPs, and battery installers are invited to make connections with them in order to maximize the value of their service. But how do installers go about selecting an appropriate ACP with whom to form a connection?

Recent Updates and Policy Changes

The PDRS scheme is evolving, with frequent revision and expansion of eligibility criteria and implementation guidelines.

With effect from December 19, 2024, some prime updates are an improvement in the definition of batteries to permit certification only for higher storage systems in PRCs, changes to eligibility criteria based on evolving standards of energy efficiency, and continuation of incentives for new solar PV and battery systems. Battery installers need to watch out for these changes in order to stay compliant and keep their customers eyeing the most attractive possible financial incentives. But what should installers be expecting in the future?

Future Outlook of Battery Installations Under PDRS

The NSW Peak Demand Reduction Scheme is a big step towards a more resilient and sustainable energy network.

For battery installers, it provides them with a route to greater business opportunity while facilitating a more stable electricity grid. Installers can look to remain ahead of PRC valuation and market developments in the next few years, informing customers about long-term financial and environmental advantages of battery storage and enhancing cooperation with ACPs and regulators to simplify incentive claims. As energy saving efforts continue to spread wider, battery storage will have a significant role in regulating the consumption of energy and grid equilibrium. Installers who make effective use of the PDRS will be in a position to drive their businesses further and help push renewable energy alternatives forward. So, what lies in store for NSW battery storage for energy sustainability?
