The project area is impacted by load growth and The project area is impacted by load growth and “ “interconnected interconnected” ” system needs system needs

Long-term planning investigation initiated by the ISO in 2003 Load growth area of 4% to 5% annually Five other alternatives were assessed The preferred alternative selected by the CAISO: The highest load serving capability Produces the required level of reliability Least environmental issues Can be implemented without CPCN or GO131D – therefore shortening the construction time Best overall benefits (cost-technical-environmental)
