The growth of DER- What is DER all about?
A distributed energy resource (DER) refers to a consumer-owned energy device. This small-scale power generation unit operates locally and connects to a larger grid at the distribution level. Examples of DERs include solar panels, solar storage batteries, electric vehicles, and controllable loads like Heating, Ventilation, and Air Conditioning (HVAC) systems and electric water heaters which enable individuals to generate, store, and manage their electricity.
Unlike traditional power sources, DERs typically consume the energy they produce close to the point of generation. To effectively utilise renewable resources and manage their intermittent nature, multiple renewable sources and energy storage systems like batteries and flywheels are necessary. These power sources and storage devices are tightly managed using electronic management devices such as solar inverters and software like Storage Distributed Resource Schedulers (SDRS). DERs find applications in residential, commercial, and industrial sectors, serving utility providers, businesses, and individuals for renewable power generation, storage, and backup power. They are integral to the development of advanced power grids, including smart grids.
Benefits of DER
The inclusion of distributed energy resources into the grid has several benefits. Customers with DER assets can expect to pay less for electricity because they can sell power back to the grid.
In areas where there is a high reliance on wind, solar and other variable energy resources (VERs), distributed energy resources can be used to help improve the quality of service and reliability of service.
Energy Matters has been a leader in the renewable energy industry since 2005 and has helped over 40,000 Australian households in their journey to energy independence.

Reliability of Australia's DER
Reliability is a paramount concern for any energy system, and DER integration is no exception. Australia’s DER framework, comprising solar photovoltaic (PV) systems and battery storage, has demonstrated commendable reliability. This reliability stems from several factors, including technological advancements, rigorous quality standards, and proactive maintenance. Government regulations, such as the Australian Standard for Solar Photovoltaic (AS/NZS 5033:2021), ensure the safe and reliable installation of solar PV systems. Additionally, manufacturers and installers adhere to stringent industry guidelines to maintain the highest quality standards.
In terms of energy generation, solar PV systems have proven to be highly reliable, especially given Australia’s abundant sunlight. Battery storage technologies have also made significant strides, with advanced control systems and improved chemistry enhancing their performance and longevity. Regular maintenance and monitoring, along with warranties provided by reputable manufacturers, contribute to the overall reliability of DER systems.
Security of Australia's DER
The security of DER encompasses both physical and cyber aspects. From a physical security standpoint, consumer-owned energy devices, such as solar panels and batteries, are typically installed on residential or commercial premises, reducing the vulnerability to physical attacks. Moreover, robust regulations govern the installation and maintenance of DER systems to prevent unauthorised access and tampering.
On the cyber front, the increasing digital connectivity of DER devices necessitates stringent security measures. Australia’s energy sector has been proactive in addressing cybersecurity concerns. The Australian Energy Market Operator (AEMO) and energy regulators work closely with industry stakeholders to establish robust cybersecurity frameworks. These frameworks outline best practices, threat mitigation strategies, incident response protocols, and information-sharing mechanisms.
The DER industry also emphasises secure communication protocols, encrypted data transmission, and user authentication mechanisms to protect against cyber threats. Regular software updates and patches help mitigate vulnerabilities, while robust data privacy regulations, such as the Australian Privacy Principles, safeguard consumer data.
The integrity of Australia's DER
Ensuring the integrity of Australia’s DER involves guaranteeing the accuracy and consistency of energy generation, consumption, and billing. This is achieved through accurate metering and monitoring systems, along with transparent regulatory mechanisms. The Australian Energy Market Commission (AEMC) sets the rules and regulations governing DER integration, including the requirement for smart meters to accurately measure and report energy flows.
Smart meters and advanced monitoring systems enable real-time visibility into energy generation and consumption patterns, allowing for accurate billing and promoting transparency. To maintain integrity, regulatory bodies monitor compliance with standards and regulations, taking appropriate action against any malpractice or non-compliance.
Consequences of cybersecurity breaches
Cybersecurity breaches in DER systems can have wide-ranging consequences. First and foremost, a successful attack on the DER framework could disrupt the power supply to individual consumers, businesses, and even critical infrastructure. This can result in financial losses, operational disruptions, and potential safety hazards. Additionally, cyberattacks targeting DER systems may compromise the privacy and personal data of energy consumers, leading to identity theft and other fraudulent activities. Moreover, interconnected DER systems can serve as potential entry points for hackers to launch attacks on broader energy networks, threatening the stability of the entire grid.
Cybersecurity breaches are of paramount concern
As Australia advances towards a DER-dominated energy future, addressing the challenges posed by cybersecurity breaches is paramount. The article highlights the potential risks and consequences associated with such breaches and emphasises the need for proactive measures. By adopting a comprehensive approach that encompasses strong authentication, encryption, monitoring, regular audits, education, and collaboration, Australia can build a resilient DER ecosystem that ensures the security, reliability, and trustworthiness of its distributed energy resources. Only by taking proactive steps to fortify cybersecurity defences can we maximise the benefits of DER while safeguarding the integrity of Australia’s future energy framework.
