The Electric Vehicle Council (EVC) provides feedback to the Australian Energy Market Operator (AEMO) on the consultation paper regarding electric vehicle (EV) data, emphasizing the importance of accurate data for planning and forecasting. The EVC highlights three key areas of focus: consumer charging behavior, EVSE deployment, and EV uptake.
Consumer Charging Behavior
The EVC criticizes AEMO's overestimation of peak-time EV charging, noting that effective time-of-use (TOU) tariffs reduce charging rates to approximately 110W/EV, contrary to AEMO's worst-case scenario assumptions. Survey data from the University of Sydney shows only 15% of EV owners charge during evenings, supported by multiple surveys indicating a consistent trend. Additionally, V2G-compatible vehicles can significantly offset peak demand, with V2G expected to expand in Australia by 2025.
EVSE Deployment
The EVC supports the use of Non-Intrusive Load Monitoring (NILM) by Distribution Network Service Providers (DNSPs) to detect Level 2 EVSE, suggesting collaboration among DNSPs to improve accuracy. Potential improvements include detecting Level 1 EVSE and other peak-demand loads like air conditioning and cooking. The EVC also recommends incorporating consumer energy resources (CER) and V2G capabilities into future initiatives.
State Electrical Safety Bodies
The EVC advocates for state electrical safety bodies to include EVSE installation data in their certificates, which could be harvested electronically. This data would help DNSPs assess network capacity and inform EVSE deployment strategies.
Network Capacity Maps
The EVC calls for improved public access to network capacity data at the transformer level, citing examples of NSW DNSPs and Victorian efforts. Such data would benefit renewable energy projects and CPOs seeking deployment locations.
EV Uptake
The EVC collaborates with AEMO to refine EV uptake projections, noting the inaccuracies in the 2024 ISP's 50% target for new vehicle sales by 2027. It呼吁 federal government-level handling of vehicle sales data for public access and better EVSE deployment planning. Registration data from state transport authorities is also highlighted as crucial for tracking EV usage.
V2G Uptake Projections
The EVC argues for more granular modeling of V2G uptake, suggesting AEMO simulate penetration rates of 2%, 5%, and 10% by 2030, given V2G's current feasibility. The EVC sets 10% as an upper bound, advocating for conservative modeling.
Additional Recommendations
The EVC suggests AEMO adopt a more reflective approach to past projections, engage in scenario validation, and include expert peer review for EV uptake and V2G forecasts. An adaptive feedback loop for annual reviews of forecasting methodologies is also recommended.
Conclusion
The EVC urges AEMO to review consumer charging behavior data, support NILM advancements, leverage state electrical safety data, collaborate on EV projections, advocate for federal vehicle sales data transparency, and refine internal processes for improved accuracy.
