The ISO is developing an opportunity for developers to deliver generation to California without increasing the Transmission Access Charge (TAC) and without picking the winner by selecting a project in the Transmission Planning Process (TPP). The ISO intends to implement the Subscriber Participating Transmission Owner model as a win-win arrangement versus trying to extract value from those paying for the line for the benefit of the ISO’s existing ratepayers. This model allows the potential off takers/California load serving entities to make their own economic decisions with respect to which out-of-state generation projects to contract with, while the ISO would continue to exercise its existing tariff authority and utilize its supporting software systems to implement a new protocol.
