Ferc Approves Wecc-wide Proxy Group For Roe On Transmission Path Upgrade

摘要

It is suitable for a transmission line owner in the West to use a region-wide proxy group in calculating returns on equity for its project, FERC recently determined.rnIn the order (ER08-374, EL08-38), the commission approved a 13.5% return on equity for a major Southern California transmission route owned by Atlantic Path 15 based on a proxy of 17 investor-owned utilities in the Western Electricity Coordinating Council, where the upgrade is located.rnAtlantic Path 15 used five screening parameters to reduce the number of companies in its proxy from 17 to nine, with a range of reasonable returns of 7.63% to 13.67%, said the order.rnAdditionally, FERC accepted the transmission owner's December filing and suspended the proposed rates until February 20, subject to refund. Atlantic Path 15 requested to decrease its transmission revenue requirement by $2.7 million to $32.1 million.rnThe upgrade is an 83 mile, 500 kV transmission line that was built in 2004 along the existing Path 15 corridor in California to relieve a seriously constrained congestion point. The project added about 1,500 MW to the 5,400 MW of transmission capacity for south-to-north flows and increased capacity for north-to-south power flows by about 1,100 MW.
