Western RTO Requested by Utilities

LCG, April 1, 2002-A group of western utilities has requested the Federal Energy Regulatory Commission (FERC) to approve its proposal for a Regional Transmission Organization (RTO) to oversee energy transactions in the west.

Sierra Pacific Power, Puget Sound Energy, Portland General Electric, Nevada Power, NorthWestern Energy, Idaho Power, British Columbia Hydro and Power Authority, Bonneville Power Administration, and Avista came together to submit the proposal.

The request would open up transmission lines over the whole region, facilitating the delivery of wholesale electricity and eliminating additional transmission fees incurred when electricity moves from one system to the next. Instead, utilities would pay one base fee to use transmission lines in the region.

The RTO, as a non-profit corporation, will cost between $125 and $140 million per year, and independent analysts project that RTO West will save $300 million.

Foreseen to be in effect around 2005 if approved, RTO West still requires a lot of assessment and paperwork. BC Hydro, as a Canadian utility, will require special authorization. Also, some utilities require state approval.
