CAISO’s First Geothermal Plant in 30 Years Comes Online

August 25, 2022

The first geothermal power plant built in more than three decades within the California Independent System Operator (CAISO) balancing authority has come online. Mammoth Pacific Geothermal, an Ormat Co. subsidiary, declared the 30-MW Casa Diablo IV (CD4) commercially operational on July 20.

CD4 is located on public land two miles east of the Town of Mammoth Lakes in Mono County, California. The project is part of the Mammoth complex, which includes three other plants—one completed in 1985 and two added in 1990—each with a generating capacity of approximately 10 MW. The complex taps into the Long Valley Caldera’s hydrothermal system at a point where the hot water is only a few hundred feet below ground.

CD4 comprises two Ormat Energy Converter (OEC) binary generating units, each 21.2 MW, and vaporizers, turbines, generators, air-cooled condensers, preheaters, pumps and piping, and related ancillary equipment. OEC binary generating units are based on an Organic Rankine Cycle, and work by vaporizing a secondary working fluid (organic, with a low boiling point) that is heated by the geothermal fluid extracted from an underground reservoir.…

DTE Energy Will Close Belle River Coal Power Plant Two Years Early

Detroit-based DTE Energy said it will cease all coal use at its Belle River Power Plant no later than December 2028, at least two years earlier than the facility’s previously scheduled 2030 end date.

The Belle River Power Plant comprises two electric generating units, each with a maximum gross design generating output of 697 MW. The 2,200-acre site on which it’s located is in China and East China Townships in St. Clair County, Michigan, and is shared with several other units including a few gas-fired peaking combustion turbines and the coal-fired St. Clair Power Plant. The Belle River units were brought online in 1984 and 1985, respectively.

DTE, which serves about 2.2 million electric customers in southeast Michigan, said retiring the facility by 2028 will enable the company to achieve its 50% carbon emissions reduction goal faster than planned and move the company closer to its ultimate goal of achieving net zero carbon emissions. DTE has already retired four of its coal-fired facilities—Marysville, Harbor Beach, Conners Creek, and River Rouge—and plans to retire its Trenton Channel and St.…

Coal Shipments to Power Sector at Lowest Level in 14 Years

The post Coal Shipments to Power Sector at Lowest Level in 14 Years appeared first on POWER Magazine.

Shipments of coal to U.S. power plants in 2020 fell 22% year-over-year, according to data released May 13 by the U.S. Energy Information Administration (EIA). The agency said the U.S. power sector received 428 million short tons (MMst) of coal last year, the lowest amount since the EIA began publishing shipment data in 2007.

The EIA said the COVID-19 pandemic was partly to blame for the drop, as demand for electricity fell nationwide. The agency in April reported that U.S. energy consumption in 2020 fell 7% year-over-year, which it said “marked the largest annual decrease in U.S. energy consumption in both percentage and absolute terms in our consumption data series that dates back to 1949.”

Thursday’s report also pointed to the ongoing decline of U.S. coal-fired power generation; federal data shows about 9.5 GW of coal-fired generation was shuttered nationwide last year, the fourth-highest total since 2009.…

The post DOE Launches Program to Demonstrate Advanced Nuclear Reactors Within 5 Years appeared first on POWER Magazine.

Bolstered by $ 230 million in Congressionally appropriated funding, the Department of Energy (DOE) has officially launched the Advanced Reactor Demonstration Program (ARDP) to help U.S.-based private developers of advanced nuclear reactors demonstrate their technology in the U.S.

Much anticipated by industry, the program formally established under the Office of Nuclear Energy program on May 14 is one of three major government-led and Congressionally supported initiatives to boost U.S. nuclear energy research and development. Congress has also appropriated $ 305 million for fuel cycle research and development, and $ 267 million for reactor concepts research, including for the industry-led Advanced Reactor Concepts program and the Versatile Advanced Test Reactor.

The National Reactor Innovation Center at Idaho National Laboratory provides resources for testing, demonstration, and performance assessment to accelerate deployment of new advanced nuclear technology concepts. These are some milestones and a tentative timeline the facility could achieve over the next decade.
