It will be the first geothermal power plant built within the California Independent System Operator (CAISO) balancing authority in the last 30 years and will be the first in Ormat’s portfolio to sell its output to a Community Choice Aggregator. The CD4 power plant is expected to be on-line in early 2022. Mammoth Pacific Geothermal currently employs 25 full-time people and expects to bring on additional employees as a result of the CD4 project. It’s estimated that the project will bring over $13 million to the region and will create more than 180 construction jobs. The state-of-the-art project is expected to provide 30MW of electricity for 22,000 homes while offsetting 4 million tons of CO2. Ormat is authorized by the US Forest Service to continue work through the recent California National Forest closure. The public is advised to be aware of heavy equipment and remain outside of marked areas. Highway 395, and installing pipelines that connect the wells to the power plant.Ĭonstruction vehicles and heavy equipment will be present and operating in the area throughout the construction period. Upcoming activities include drilling new geothermal wells at two sites near Shady Rest, building a new power plant east of U.S. We had previously reported on flow and injection tests done by Ormat on two existing geothermal wells in the project. Resource extraction projects on federal land, like Casa Diablo IV, pump royalties and money “in lieu of property taxes” into local economies.In a press release, Ormat Technologies through Mammoth Pacific Geothermal announced that construction work for the Casa Diablo IV (CD-4) geothermal project in Mammoth Lakes, California has started. If the project is not delayed significantly, according to Dan Lyster, Mono County’s economic development coordinator, construction could begin on the plant within “the next few years.”Īccording to Ormat, the project will bring millions of dollars-around $9.1 million-to Mono County, and more during its one-year construction period. Forest Service and the state’s Great Basin Unified Air Pollution Control District are cooperating lead agencies for the project The prospect of such a large pipeline running though one of Mammoth’s most highly used recreation areas-a pipeline that could be several feet in diameter-has alarmed local recreationists, the Town of Mammoth Lakes, and others, prompting an influx of comments in recent weeks. The approximately nine-mile-long pipeline is proposed to run from wells located to the north and east of Mammoth Lakes, including wells near Shady Rest Park. The proposed plant, called the Casa Diablo IV plant, will include as many as 16 new wells and the pipeline to bring the geothermal brine from those wells to the plant. The comments are now due to the appropriate federal offices (see sidebar) by close of business Wednesday, Jan. BLM extended the public comment period on this draft, originally due on Jan. In the meantime, the project is undergoing a federally mandated environmental review process, called a draft Environmental Impact Statement (EIS). The project is in the planning and environmental review phase and is expected to come to fruition several years from now, if it is approved by the federal land agencies on whose land it will sit. The 38-megawatt geothermal plant is proposed for a site adjacent to the existing Casa Diablo Road geothermal complex, tucked up against the volcanic bluffs to the east of the complex. Last week, the Bishop Bureau of Land Management (BLM) extended the time to comment on the project to Jan. Residents now have more time to weigh in on what could be one of the biggest infrastructure projects in Mono County’s history.Ī brand new geothermal plant that will generate as much power as all three existing Ormat Technologies power plants east of Mammoth Lake is in the works.
