Areas of focus

An emerging discussion around the integration of transmission and distribution operations in real-time.

Transmission operations are reshaping under large loads, the 765 kV buildout, and inverter-based resources. This is the peer room where operators work through it and founding members help set the direction.

TSO is the peer forum for real-time and near-real-time transmission operations — control-center decision-making, operator tools, event response — and for preparing operators and processes for the emerging environment of large loads, 765 kV, IBR, and FERC Orders 881 and 2222.
