​Review transmission access charge wholesale billing determinant

This initiative will consider modifying the transmission access charge (TAC) wholesale billing determinant to exclude the end-use load that is offset by the energy produced by distributed generation. The ISO currently allocates the TAC to each MWh of internal end-use load and exports to recover participating transmission owners' costs of owning, operating and maintaining transmission facilities under the ISO operational control. This topic was originally included in the Energy Storage and Distributed Energy Resources Phase 2 initiative.

 

Initiative status

Policy development: Initiative closed. The scope needed a broader review of the TAC design. A new initiative
to address this is planned to launch midyear 2017.
