Southwest Power Pool Granted Conditional RTO Status

LCG, Feb. 10, 2004--The Southwest Power Pool's application to be considered a regional transmisson organization was given conditional approval by the Federal Energy Regulatory Commission (FERC) today.

The power pool is spread through eight states in the Southern Great Plains, and first applied for recognition as an RTO two years ago. At that time, FERC's vision for large, regional markets was such that the SPP was considered too small to provide competition and a fair market environment.

The chairman of the FERC, Pat Wood III, said in a statement, "I am pleased that, at last, we have the opportunity to recognize the important role that the Southwest Power Pool plays in providing needed leadership for the power markets in the nation's heart." The approval was granted with corresponding requirements that an independent board, an independent market monitor, and clear daily control of transmission be set up.
