The Federal Energy Regulatory Commission (FERC) has released proposed rules for real-time information networks and standards of conduct, a "critical" supplement to its electric transmission open-...

to society. However, one should not expect the "losers" to support the structural change without assurances of appropriate transition arrangements. Once the industry becomes comfortable with the likelihood of net benefits from RTO formation, assuming they can be credibly demonstrated, the debate needs to evolve from identifying winners and losers. Instead,in order to move RTO development forward, the focus needs to be on developing the mechanisms to equitably distribute net benefits, at least over some transitional period.

- While the five studies described all quantify the benefits of RTO formation, only one looks at the potential costs. However, for the purpose of this article we will refer collectively to these analyses as cost/benefit studies. Additional studies are expected for PJM-MISO-SPP, Entergy (Louisiana and Arkansas) and by the Southeastern Association of Regulatory Utility Commissioners (SEARUC).

- In the transmission-constrained curtailments case, transfer limits were set equal to actual flows in transmission-constrained hours. In the reduced interface limits case, the transfer limit was set at the higher of actual flows or the actual average flows during constrained hours. Steeper sloping supply curve estimates were applied in both the NYISO and PJM markets.
- PJM used the GE Multi-Area Production Simulation (GE MAPS) model to simulate hourly locational marginal prices in the three individual northeast markets assuming separate unit commitment and dispatch functions. The RTO West study also used GE MAPS to model the RTO West and WSCC regions.
