Nevada Power's $961 Million Rate Hike Not Half Enough;Casino Operators Balk at Prospect of $1 . Billion More

LCG, Dec. 28, 2001--Nevada Power Co., which has asked state utility regulators for a whopping $961 million (as in $0.96 billion) rate increase could be back asking for another rate hike of about $1 billion a year from now, the Las Vegas Review-Journal reported yesterday.

Casino operators, who are pretty good on figuring the odds, think it could happen and are unhappy about it.

The Nevada Energy Buyers Network, which represents casinos and other commercial customers, questioned the way Nevada Power based part of its proposed rates on future costs. The utility has based those costs on prices in contracts for wholesale power it either can't or chooses not to generate itself.

Nevada Power is confident it can renegotiate contracts with wholesale power providers so that it will pay less than the contract terms. Based on those assumed renegotiations, Nevada Power projects that its "going forward" cost should be 5.4 cents per kilowatt hour. But other utility documents show the rate should be 11.8 percent per kilowatt hour, the paper said.

The difference between the two is about $1.05 billion in annual revenue for Nevada Power.

Steve Boss, president of the buyer's network, said "The magnitude of the increase is a substantial financial impact on our clients, and our clients want to make sure in fact that the costs were prudently incurred as required (under state law)."
