The Public Utilities Commission of Nevada (PUCN) today approved an increase in electric rates for NV Energy's (NYSE: NVE) utility serving southern Nevada.

The increase is a result of the company's mandatory General Rate Case (GRC) filing made in December, 2008. The Commission has instructed the company to implement new rates in a two-phase process. The projected net impact on residential customers from both phases is expected to result in a total increase of approximately 6.9 percent annually.

The first increase, 3 percent, will take effect on July 1, 2009. As disclosed by the PUCN today, the typical residential customer using 2,181 kilowatt hours of electricity per month in July, August and September, will see a bill increase of $7.68 per month.

The second increase, an estimated 3.9 percent, would follow on January 1, 2010. This increase includes the remainder of the PUCN's order today minus an estimated decrease in the Base Tariff Energy Rate (fuel and purchased power costs) resulting from declines in natural gas prices.

The PUCN established an overall rate of return for the company of 8.53 percent and a return on equity of 10.5 percent. The overall revenue increase to the company is approximately $221 million.

NV Energy customers are encouraged to take advantage of specific programs that will ultimately help curtail the dollar impact of the increase, such as the Equal Payment Program, which spreads costs evenly over a 12-month period, as well as utilize new features offered by the company through "My Account" at nvenergy.com. The website features tools that will help customers track energy consumption and determine savings opportunities through a variety of energy conservation and efficiency programs.
