Soda Lake Geothermal Plant

The Soda Lake Operation is located in the southwest portion of Churchill County, Nevada, approximately 11 km northwest of the city of Fallon and 115 km east of Reno. The Soda Lake Operation consists of 2,881 hectares (7,119 acres) of private and federal lands.

The Soda Lake Operation is accessible by paved and gravel roads. Two major highways, Interstate 80 and U.S. Highway 50, are located in close proximity to the project area. The power plants and all production and injection wells are accessible on all weather gravel and dirt roads.

The Soda Lake Operation is in close proximity to 120 kilovolt ("kV"), 230 kV and 345 kV transmission lines. Additionally, the area is served by a regional railroad line, which passes immediately to the south.

The Soda Lake Operation sells all electricity to NV Energy Company, a wholly owned subsidiary of Sierra Pacific Resources Company, Reno, Nevada, under two 30-year power purchase agreements.

Our Soda Lake Operation is comprised of two power producing facilities, Soda Lake 1 and Soda Lake 2, with a total installed gross nameplate capacity of 23.1 MW. Soda Lake I has an installed gross nameplate generation rating of 5.1 MW and is equipped with a water-cooled condensing system. Soda Lake II has an installed gross nameplate generation rating of 18 MW and is equipped with an air-cooled condensing system. Soda Lake 1 and Soda Lake 2 came on line in 1987 and 1991, respectively.

Electricity sales from the Soda Lake Operation have averaged 8 MW net over the period 2005 to 2008. Based on the recommendations set out in the Soda Lake Report, we intend to continue the expansion program and increase net electricity sales to approximately 16 MW by March 2010, by drilling two new production wells and upgrading surface piping and existing equipment.

Contingent upon completion of the expansion of existing net power output to approximately 16 MW and additional reservoir definition, Magma intends to add additional power generation units to increase nameplate capacity to the P90 estimate of the geothermal reservoir's gross generation capacity of 28.8 MW, and potentially up to the P50 estimate of 54.8 MW.
