FERC Reiterates Rule on Transmission Interconnection

LCG, Mar. 3, 2004--A rule designed by the Federal Energy Regulatory Commission and first outlined in July 2003 was given further publicity today, based on the agency's interest in promoting and clarifying its position on non-discriminatory transmission access.

The specific area of the rule detailed by FERC concerns upgrades to transmission, and how much the provider may charge its interconnected customer. The provider has an option of charging a transmission rate that is the incremental cost for any upgrades associated with the interconnection, but it may also charge the average embedded cost rate across the transmission system. The agency is of the opinion that allowing the provider to charge the higher of those amounts would mean that existing transmission customers would not in effect be required to pay for new interconnections by merchant generators.

The rule affects close to 176 investor-owned public utilities owning, operating or controlling interstate transmission.
