Planning for Interconnection of Wind Plants Based on Net Maximum Capacity

This paper discusses whether changes to wind turbine versions, quantities, or upgrades will affect the process leading up to an LGIA (Large Generator Interconnection Agreement), or whether similar modifications implemented after a wind plant developer has completed and signed an LGIA require reevaluation of the system impact study (SIS).This paper provides background information followed by quantitative examples to help facilitate this discussion. Quantitative examples here are based on modifications to 1.5MW turbines, but are applicable to any alterations that may increase the total power output of turbines (measured at the wind turbine terminals) beyond the initially submitted interconnection power rating.
