Geothermal 101
Attribution: USGS
George Gorski over at Seeking Alpha has posted a nice entry on geothermal entitled “Geothermal 101” – it’s a very good read and has the added benefit of exploring the geothermal supply chain in addition to developers and operators. It succeeds in giving a baseline education on the types of harvest techniques, the development challenges and benefits, and in the publicly traded companies participating in the industry.
Mr. Gorski, if you read this, there is one major correction to your article: Calpine (of San Jose – not San Diego) operates 19 of the 21 plants at The Geysers. The Northern California Power Association operates the other two. Also, two new developer/operators are working in The Geysers, US Renewables is re-powering a the old DWR Bottle Rock plant and Western GeoPower is re-powering the old PG&E Unit 15 plant. There are many more plants in California in the Mammoth, Coso, and Imperial Valley regions. Otherwise, a very good article and highly recommended.
