The roles and responsibilities of electricity distribution networks are being challenged by the changing mix of resources in the grid. The energy transition is not just about reducing emissions by changing technologies in large-scale generation, it is also about a trend towards more localised, or distributed energy resources (DER). The Australian Energy Council’s latest discussion paper looks at what the transition might mean for distribution networks and customers.
The role of consumers in the energy transition will continue to grow in significance. The Australian Energy Council’s members and other energy sector participants recognise the increasing role of CER in the energy transition as well as the value it can deliver to consumers.
By the end of the first quarter this year solar PV installations had put been fitted to more than 3.7 million Australian rooftops with a capacity of 22.58GW, according to the Clean Energy Regulator. In addition to the latest installation statistics, we take a look at other developments with rooftop solar, as well as the impact utility-scale solar is having on price setting in the National Electricity Market.
Since market start the NEM has used a single and simple outcome metric for its reliability standard: “Unserved Energy” (USE). Essentially, we target an average of no more than 10.5 minutes off supply per customer per year from rotational load-shedding. In response to a Reliability Panel Review, the Australian Energy Council has published a report by Endgame Economics that theoretically contemplates the appropriateness of the existing standard in the transitioning power system and concludes that the existing simple USE output form approach remains the best approach for the future power system, just as it is in the current power system.
