Southeastern Grid Plan Gains Momentum

LCG, Oct. 11, 2002--An outline for a regional transmission organization (RTO) that would serve an area extending from South Carolina to Louisiana and central features concerning its management were approved by a 4-0 vote by the Federal Energy Regulatory Commission (FERC), allowing its supporters to develop a full, detailed proposal for an entity known as SeTrans.

The design of SeTrans has been developed thus far by Southern Co., which has a significant transmission presence in the Southeast, Entergy Corp., based in New Orleans, and by nine municipal and public providers of power. The states seen as having at least part of their transmission grid overseen through SeTrans also include Georgia, Florida, Alabama, Mississippi, Arkansas, and Texas.

The approval of the outline raises the likelihood that the formal proposal will be substantially accepted by FERC as conforming with its proposed rules concerning grid reliability, tariff design, and an independent grid administrator.
