INFRASTRUCTURE FOR THE FUTURE INVESTMENT IN INNOVATION Building resilient networks for future generations Victoria Power Networks Solar Enablement Program Currently being considered by the Australian Energy Regulatory (AER) this program represents a $93m investment over five years that will enable most customers to connect their 5kVa solar PV system and ensure 95% of customers are able to export to the grid This program will remove solar constraints where it is economic to do so – that is where the benefits to customers outweigh the costs - and assist customers where it is not LiDAR Lab VPN has established a new LiDAR processing lab to perform vegetation inspection, focused on identifying multi-circuit clearance breaches. Through automated modelling, the inspection needs to be accurate to within 5cm, as such the models have been rigorously audited to provide assurance to the business and maintenance teams. The LiDAR Lab project will see all LiDAR services moved in-house by 2021 to improve quality, minimise risks, reduce work hours and reduce costs SA Power Networks Upgrade Low Reliability Feeders 午 SA Power Networks have pursued a program to upgrade low reliability feeders in their worst performing parts of the network. This program was not required under the National Electricity Rules (NER) and was originally rejected by the AER in their draft decision Following further consultation with the Consumer Consultative Panel the program gained unanimous consensus and the upgrade was accepted in the AER's Final Determination based on the significant stakeholder support Solar-Sponge Tariff South Australia has the highest per capita level of rooftop solar. SAPN has created an innovative tariff structure for residential customers. This tariff offers a lower network charge during the middle of the day when solar output is highest, to encourage shifting of electricity use to those times Raising demand for grid supplied electricity in the middle of the day can help manage voltage issues and thermal overloads associated with low demand, while shifting demand away from the evening peak that can put heavy strain on the network Spark Infrastructure I Investor Presentation | August 2020 19
