California Will Not Collect $2.8 Bln Refund
LCG, May 30, 2002--An argument submitted in March to the Federal Energy Regulatory Commission by California Attorney General Bill Lockyer, seeking refunds for $2.8 billion in alleged power purchase overcharges, was rejected today by the agency's commissioners.The charges in question were incurred during the period May through October 2000, for purchases made by the state from power marketers. Normally, such complaints over power sales are required to be filed 60 days from the date of purchase, but Lockyer told the FERC that the fact that quarterly reports filed by the companies did not disclose specific transactions justified waiving that requirement. The FERC agreed with Lockyer insofar as it found less detail in the reports than is required. In its order, however, it said, "The reporting deficiencies identified by the attorney general in the quarterly reports, while serious and in need of correction, do not invalidate market-based pricing tariffs as lawful, filed rates."Another, similar case filed by Lockyer seeks $8.9 billion in refunds. The case, which is still pending before the FERC, covers the later period of October 2000 through June 2001. Reports from some companies, among them Williams Cos, Mirant Corp., Reliant Energy, and Dynegy Inc., were considered insufficiently detailed by the FERC, which allowed 30 days in which the reports would have to be re-filed. The transaction records sought by the FERC would detail short-term sales to the California Water Department, the California Power Exchange, which is no longer operating, and the California Independent Sytem Operator (ISO), beginning in 2000 and through all of 2001. The transactions had earlier been submitted in aggregated form.
