Economic Planning

Reliability planning sets the stage for economic planning. The Congestion Assessment and Resource Integration Study (CARIS) examines congestion on New York’s transmission system and the relative costs and benefits of generic projects to alleviate that congestion.  Specific projects are evaluated in a second phase of the economic planning process.  If 80 percent or more of the weighted vote of beneficiaries vote in favor, the costs of the project can be allocated to all beneficiaries through the NYISO’s tariffs. The NYISO’s economic planning process was developed in response to Order 890 of the Federal Energy Regulatory Commission (FERC). It integrates a local planning process for each transmission owner with the existing reliability planning process and the CARIS into an extended two-year planning cycle.
