First, Google signed a new, 25-year agreement for power generated at the Duane Arnold Energy Center, Iowa's only nuclear power facility. The 601-MW boiling water reactor unit was shut down in 2020 and is expected to commence operations by the first quarter of 2029, pending regulatory approvals to restart the plant.

Water Authority Agrees on Buyout Offer for Nevada Power

LCG, July 19, 2002--A meeting of the Southern Nevada Water Authority board resulted yesterday in a unanimous vote to tender an offer for Nevada Power Co., under the holding company Sierra Pacific Resources.

The water authority is affiliated with the Las Vegas Valley Water District, and provides municipal governments with water. It has been in discussions with Morgan Stanley, the investment bank, concerning underwriting of a buyout. The organization's general manager, Pat Mulroy, drew attention to Long Island, N.Y., which undertook a buyout of an investor-owned utility, resulting in the Long Island Power Authority.

According to Mulroy, the risk to ratepayers if Nevada Power is not bought out is in the form of higher rates, as the power company tries to improve its credit rating and overcome a poor cash situation. She said that with a buyout, rates would not have to rise.

The mayor of Las Vegas, Oscar Goodman, raised the issue of a loss of property taxes and franchise fees, now at about $26 million. Lyle Miller, managing director of Morgan Stanley, responded that under such situations, a utility often makes payments in lieu of taxes. A North Las Vegas City Council member, Shari Buck, described herself as a "cautious supporter" of the possibility being raised, and said her interactions with Nevada Power have been "very very positive."
