Utility regulators say Entergy subsidiary's rate filing undermines related ALJ decisions

摘要

Regulators of a group of utility affiliates that buy power from the Grand Gulf Nuclear Station in Mississippi are pushing back on formula rate changes proposed by the nuclear facility’s majority owner System Energy Resources. SERI argues that the changes would result in a rate reduction, saving ratepayers more than $68 million over the remaining expected life of the Grand Gulf facility. But critics urged the Federal Energy Regulatory Commission to reject the proposal as they assert it “undercredits rate base by hundreds of millions of dollars.” At issue are capital costs that SERI’s ratepayers have been billed for but the company has not actually incurred related to tax deductions taken for future decommissioning expenditures for Grand Gulf. SERI, a subsidiary of Entergy, owns 90% of Grand Gulf and sells wholesale capacity and energy from the 1.4 GW nuclear generator to four of its affiliates – Entergy Arkansas, Entergy Louisiana, Entergy Mississippi and Entergy New Orleans – under a unit power sales agreement (UPSA).
