In previous posts, I have explored innovative business models that aim to maximize the value of solar plus energy storage systems in Australia. The country has quickly become a leading market for these technologies—as well as the advanced business models and platforms necessary to unlock their full potential.
Navigant Research tracks the rapidly growing Australian market through its new Energy Storage Projects Data Service, which provides unique insights into the dynamics of markets around the world. As shown below, the majority of storage systems in Australia are being used to integrate new solar projects and maximize their value for both customers and the grid.
While the Australian market for both solar and energy storage has grown exponentially in recent years, these technologies will only be an economical investment for select customers given current business models and regulations. A new program being launched by software provider GreenSync hopes to change this situation by opening new opportunities for customers to benefit from its distributed energy resources (DER).

GreenSync’s software-based marketplace, known as the Decentralized Energy Exchange (deX), aims to provide an avenue for distributed solar PV and energy storage system owners to trade their system’s services with local network operators in exchange for payments. Initially, the primary goal of the exchange will be to help operators manage both peak demand and variable solar generation on the grid. The opening launch of the marketplace will focus on trials with two utilities. ActewAGL, in Australia’s Capital Territory, hopes to understand how market-integrated batteries can alleviate constraints in certain parts of the grid, particularly those struggling to handle high levels of solar PV. United Energy in the Melbourne area is piloting the deX marketplace to reduce grid congestion where summer peak demand is straining existing infrastructure.
These utilities join a number of others in Australia that are working to understand how networks of DER can be utilized to provide services for grid operators in addition to the customers who own them. Utilities like AGL Energy, SA Power Networks, and Ergon Energy are working with various vendors to maximize the value inherent in energy storage systems and other flexible DER to improve the efficiency of the grid while allowing for greater amounts of solar PV to be added by customers.
Coordination Is Key
For DER providers to reach the most customers and realize the full potential of their technologies, these types of virtual aggregation platforms will be essential. Without proper coordination, the growing number of DER on the grid can result in significant systemwide inefficiencies, and their benefits may only be accessible to select electricity customers. Collaboration and coordination among DER stakeholders on the grid are key themes explored in Navigant Research’s recent white paper, Navigating the Energy Transformation.
The ability to effectively aggregate and coordinate distributed systems will be crucial for both utilities and vendors to capitalize on all the values these systems can provide. Vendors with a narrow focus on only providing cost savings and backup power for customers will significantly limit their addressable market, as their solutions may be too costly for many customers. They also risk missing out on the opportunity to play a foundational role in the development of the next-generation transactive energy system that will transform the industry.
