Development of Two Solar-thermal Electric Hybridized Power Plant Debuts in Southern California
Solar MW Energy, Inc and affiliate Ecosystem Solar Electric Corp has commenced the development of two solar-thermal electric hybridized power plant facilities of this type in the aggregate of Nominal 675 megawatts (MW), to be located westerly of Cuddeback Dry Lake, County of San Bernardino, Southern California Mojave Desert.
These facilities, considered to be "plant-within-a-plant" will utilize at the solar field substantially improved tried-and-true Concentrated Solar power (CSP) technology, coupled with 3 underground molten salt (MS) storage tanks and associated equipment at the power block, to be sited on 320 acres of privately owned land by the developer, in two of the highest solar insulation zone/ solar-radiation in the world.
This development is an addition to already commenced developments by the developer of two other "jewels", with identical design system for solar-thermal-hybrid electric power plants, to be located in Kern County and near Barstow, Southern California Mojave Desert, USA.
The unique design of Twin Parabolic (mirrors) Collectors and Twin Parabolic Receivers (tubes not be confused with pipes), at levelized costs of less than half of other solar farms will be implemented.
These plants will dwarf all other solar-thermal-hybrid farms in megawatt-hours production, in addition to substantially reducing the use of fragile and sensitive Mojave Desert land for solar thermal power plant's siting.
The first parabolic receiver heats Therminol, a Heat Transfer Fluid (HTF) to over 400°C, during an average of 8 hours of daylight's sun radiation, which is sent to a boiler to produce steam that operates a steam turbine. The second receiver also heats HTF to over 400°C, during an average of 8 hours of daylight's solar radiation and transfers the HTF to an underground, dual stem wall concrete storage tank containing molten salt, a unique system which will foster another 8 hours of electric power production, thus doubling the capacity.
All the heat that results from the 24 hour of hybridized system operation is re-directed to foster a combined cycle operation, utilizing the waste heat recovery system.
The entire cycle of this super hybridized facility aims to produce reliable and firm delivery, 24 hours a day, 365 days a year of baseload, as well as super-peak electric power to the grid, sufficient enough for over half a million homes and business facilities in Southern California.
The proposed facility will support the State of California's goal of increasing the percentage of renewable energy supplies.
The benefits of the proposed projects and facilities will outweigh the environmental and social costs.
These facilities are to be developed at a levelized cost of about 6 cents per kilowatt-hour (kWh), which is about the same as that of coal plants, when taken into consideration that coal plants have to pay for their heavy emissions, construed as their additional levelized costs.
Although, the world wants renewable energy now, it is not appropriate to completely shut down heavy fossil fuel plants for about 15-25 years, causing an economic disruption in the global economy.
A gradual and responsible conversion to renewable energy is necessary, with a fuel mix of approximately 15 to 25% of renewable energy and 85 to 75% of fossil fuel, particularly the cleanest, being natural gas.
Permitting solar-thermal-electric hybrid power plants is a year long process which also involves public participation and virtually all Federal, State and local Governments involved in the permitting by the lead agency, the California Energy Commission.
Currently, merchant plants of this type and utility-scale will most likely trigger the development, in the near future, of massive solar-thermal-hybrid power plants of over 1,000 megawatts.
