Sierra Geothermal Power Corporation (SGP) is a renewable energy company, focused on geothermal exploration and development in North America. The company currently holds geothermal leases, or options to leases, on 17 different properties in Nevada and California. These leases extend over more than 88,000 acres (880 sq km) and have a potential generation capacity of more than 400 MW of power.

SGP is actively developing five of these properties. The Reese River, Silver Peak, Wilson and Alum projects are 100% owned and operated by SGP. SGP also holds a 50% interest in the Pumpernickel Valley project. Combined, these projects have the potential to generate between 100 and 205 MW — enough power to supply approximately 80,000 to 168,000 households.

The remaining 12 properties form a robust pipeline that will ensure SGP's continued growth.
