Transmission Benefits and Cost Allocation.

Abstract:

“The cost of transmission facilities must be allocated to those within the transmission planning region that benefit from those facilities in a manner that is at least roughly commensurate with estimated benefits.” (FERC 2010, p. 91) Benefits include reliability, economic and public policy related impacts. Turning the principle into a workable policy is important as a support for restructured electricity markets. A challenge is to make the different measure of benefits commensurable, and to find approximations that honor the principle without imposing a standard of perfection. A framework for such cost allocation uses examples from existing models and transmission investment studies to describe how the cost allocation principle could apply within the limits of available analytical capabilities.
