Australia has one of the highest proportions of households with PV solar systems in the world. With record high retail electricity prices, comparatively low feed-in tariff rates for exported PV energy and rapid reduction in energy storage costs, the market for behind-the-meter battery energy storage systems has the potential to increase dramatically. The two critical aspects of battery energy storage systems are safety and performance. At present, there is limited information available to allow consumers to make an informed choice regarding the performance of battery systems.
A project consortium consisting of DNV GL, CSIRO, Smart Energy Council and Deakin University was established in mid-2018 to develop a proposed performance testing Standard for battery energy storage systems connected to residential and small-scale commercial solar photovoltaic (PV) systems. During Stage 1 of this 2-year project a Standards review & gap analysis was undertaken to inform the development of the battery performance standard. The focus of this review was to provide a snapshot of the regulatory and Standards framework relevant to the ABPS; identify coverage and relevancy of current local and international performance standards; and identify gaps where further work is needed to establish appropriate performance testing protocols or reporting requirements to enable improved product comparisons for consumers. This presentation outlines the methodology and conclusions drawn from this gap analysis activity.
