Transmission Planning re: Congested Generation ROS Directed PLWG to consider issue discussed at January ROS Mtg – The question was raised whether transmission system upgrades should be identified to increase access to grid for constrained generation throughout ERCOT – ERCOT’s work to assess potential system upgrades to relieve potential future congestion in Panhandle (PREZ studies), while no similar assessment of existing constrained generation in other areas of ERCOT, was offered as an inconsistency in addressing generation congestion on the ERCOT Grid. – Discussions will assess how best to address the issue. – A review of current Planning Guide, Protocol, and PUC Substantive Rule language may be appropriate to serve as a basis for identifying what is currently the required planning responsibilities for ERCOT and the TSPs.
