Note: Hosting capacity maps are published by many utilities. Key constraints are thermal limits, voltage rise, and protection coordination. Smart inverters can increase hosting capacity by 20-50%.

Reference

Thermal Limit = Feeder Rating x Thermal Margin Voltage Limit = Min Load / Voltage Margin x 5% Hosting Capacity = min(Thermal, Voltage, 1.5 x Min Load) Available = Hosting Capacity - Existing DG Rule of thumb: hosting ~15% of feeder peak
