AI summary E3 modeled four scenarios for EV load shapes based on access to rates and charge management, evaluating impacts on load and system peak. Scenarios include unmanaged charging, blended, managed with TOU, and managed with VGI aggregation, considering TOU responsiveness and load management techniques.

Hourly load forecasts Load forecasts were developed at an hourly level for a full year for each scenario identified in Section 4. Load forecasts across the entire LDV population are averaged to give a per vehicle profile. [Figure 3-6](#pag...

AI summary The document discusses hourly load forecasts for light-duty vehicles (LDVs) in Nova Scotia, comparing unmanaged and managed charging profiles. Unmanaged charging occurs primarily in the early evening, while managed charging, influenced by Nova Scotia Power's time-of-use (TOU) rates, shifts charging to off-peak hours. These profiles are used in cost-benefit analysis and total load forecasting.
