Alterra Power: Peru Subsidiary Authorized to Explore Arequipa Region
Magma Energía Geotérmica Perú, a subsidiary of Alterra Power, has been authorized by the Energy and Mines Ministry of Peru for geothermal exploration in Arequipa region. The company now holds 9 geothermal exploration authorizations in the country.,

Calpine Corp: Department of Conservation Honors The Geysers for 12th Consecutive Year
Calpine Press Release — On June 20, the California Department of Conservation’s Division of Oil, Gas and Geothermal Resources (DOGGR) presented its annual Outstanding Geothermal Field and Lease Facility Maintenance Award to The Geysers for the Prati lease operated by CPN Wild Horse Geothermal, LLC.  This is Calpine Corporation’s 12th consecutive annual lease award.  Currently, CPN Wild Horse Geothermal operates 16 wells in The Geysers Geothermal field, seven of which are located on the Prati lease.  Altogether, Calpine operates 326 active wells and 15 power plants in The Geysers geothermal field that are capable of producing 725 megawatts of clean, reliable, renewable power.

ElectraTherm, Ormat Technologies: Reno-Area Geothermal Facilities Tour Recounted
An article on gives feedback on a geothermal facilities tour organized in conjunction with the recent GEA National Geothermal Summit in Reno, Nevada.  Two GEA member companies: Ormat Technologies, Inc. and ElectraTherm, Inc.  made their northern Nevada geothermal power plants available for the rare field trip.  Reporter Michael Rafferty must have paid attention on the guided bus tour through geothermal valley (aka the surrounding geology of Reno-area Nevada) as he takes us through geothermally heated swimming pools in Reno subdivisions; the geothermal heating/cooling system at the Peppermill Casino which has housed the GEA’s Geothermal Energy Expo on several occasions; and on to the featured facilities of the tour.  “Ormat’s Steamboat Springs complex is recognizable by the odd-looking collection of closely spaced pipes that hug the ground as seen from U.S. 395,” Rafferty says, and on to Ormat’s Brady geothermal power plant. The final stop was ElectraTherm’s 50 kw generator at the Florida Canyon Mines which utilizes the hot water from the gold leach field to power the mines. The system is so small it fits in a small cargo container — a contrast to the larger fields of Steamboat Springs, which produces enough energy to power the city of Reno.

Ormat Technologies: PV Plans Near Geothermal Plant in California
Ormat Technologies is making plans for their first photovoltaic power plant, located in Imperial Valley, California near the company’s geothermal power plant. ET Solar Group Corp. is supplying 10.8 MW photovoltaic modules for the project expected to generate approximately 24,500 MWh of power per year.

U.S. Geothermal Inc.: Drilling Complete at El Ceibillo Project
US Geothermal Press Release (Boise, Idaho) June 25 — (NYSE MKT: HTM; TSX: GTH) U.S. Geothermal Inc., a leading renewable energy company focused on the development, production, and sale of electricity from geothermal energy, announced today that its wholly owned subsidiary, U.S. Geothermal Guatemala, S.A., completed drilling well EC-1 at the El Ceibillo Project.

Well EC-1 was drilled to a total depth of 4,829 feet (1,472 meters) and encountered a bottomhole temperature of 491°F (255°C), with the temperature gradient at the bottom of the hole rising at a rate of 7.1°F/100 Feet (129.1°C/km). High temperatures in excess of 392°F (>200°C) were encountered in the well beginning at a depth of 2,625 feet (800 meters), which represents a potential high temperature reservoir interval in excess of 2,204 feet (672 meters). Permeability was encountered and a slotted liner capable of supporting production was placed in the well. A preliminary cleanout flow from the well looked favorable and warrants formal testing. Flow test equipment is currently being fabricated for a planned test, which is expected to be performed within the next 4 to 6 weeks.

Well EC-1 was originally planned for a depth of 3,280 feet (1,000 meters), however due to favorable drilling conditions, geology, and increasing temperature; the well depth was extended and was completed within the original budget.

“We are very excited about the preliminary results seen from our first production depth well at our El Ceibillo project in Guatemala”, said Doug Glaspey, President and COO of US Geothermal. “Reservoir temperatures within the El Ceibillo area of our concession are significantly higher than we anticipated, and as a result of favorable drilling conditions, our projected drilling costs for production size wells appear to be at or lower than we have planned.”
