Abstract: The disclosed technology includes systems and methods for determining network upgrade costs of a renewable energy project for an electricity generator. An example method can include selecting a region of an electric grid and receiving power flow data for the region. The method can include determining at least one overloaded electrical component based at least in part on the power flow data. The method can further include determining a network upgrade cost for the overloaded electrical component. The network upgrade cost can be based on one or more location-specific rules and electrical component upgrade cost data. The method can include generating a cost table based on the network upgrade cost. The disclosed technology can include a system configured to implement any embodiments of the methods for determining the network upgrade costs discussed herein.
