NV Energy and Waste Management Complete Power Purchase Agreement for Landfill Energy Project in Storey County, Nevada

NV Energy (NYSE: NVE) and Waste Management (NYSE: WM) today announced a 20-year power purchase agreement for the sale of renewable energy produced from a three-megawatt landfill gas-powered project to be located southeast of Reno at Waste Management’s Lockwood Landfill. The facility is expected to be generating renewable energy by late 2011.

The Lockwood Plant will use landfill gas extracted from a series of wells at the landfill and use that gas in a state-of-the-art turbine-generator to make renewable electricity for NV Energy customers. Waste Management currently has 115 landfill gas-to-energy facilities operating at its landfills throughout North America.

NV Energy’s CEO and President Michael Yackira noted that the Lockwood Landfill project provides an environmental benefit for Nevada, as well as a reliable and consistent renewable energy resource for customers.

"This project is noteworthy because it recovers otherwise unused landfill gas, cleans the gas with the latest technology, and then uses that gas as fuel to generate renewable energy for our customers,” Yackira said.

Waste Management’s Area Vice President Alex Oseguera said, "We take a once-wasted commodity and turn it into a long-term, reliable source of renewable energy, which is a major environmental plus for local communities.”

NV Energy currently has more than 1,200 megawatts of geothermal, solar, wind, biomass, small hydro, and waste-heat recovery under contract that are either in commercial operation or in the project development stage.

This project also helps move Waste Management toward meeting one of its sustainability goals of doubling its renewable energy production.

The agreement is subject to the approval of the Public Utilities Commission of Nevada.
