IVANPAH プロジェクト(建設中)
BrightSource’s LPT solar thermal system is currently being deployed at the Ivanpah
Solar Electric Generating System (ISEGS) in California’s Mojave Desert. Ivanpah,
which started construction in October 2010, is the first project that will deliver power to
serve the company’s signed contracts with PG&E and Southern California Edison. The
project - which counts NRG Solar, Google and BrightSource as equity investors - is
currently the largest solar plant under construction in the world. The project is being
constructed by Bechtel.
Ivanpah is also designed to maximize the economic benefits for California’s High Desert
community. In December 2009, BrightSource Energy’s engineering partner, Bechtel,
signed a project labor agreement with the State Building and Construction Trades
Council of California (SBCTC), and the Building & Construction Trades Council of San
Bernardino and Riverside Counties to provide qualified, skilled craft workers for the
Ivanpah project. In addition to providing good jobs, the project will also result in
significant state and local tax revenues.
A 392 megawatt (gross) solar complex using mirrors to focus the power of the sun on
solar receivers atop power towers.
The complex is comprised of three separate plants to be built in phases between 2010
and 2013, and will use BrightSource Energy’s LPT solar thermal technology.

Chevron/Brightsource Solar-to-Steam Demonstration FacilityChevron Technology
Ventures and BrightSource have partnered to build the world’s largest solar thermal
enhanced oil recovery demonstration facility. The 29 megawatts thermal solar-to-steam
facility will support enhanced oil recovery efforts at Chevron’s oil field in Coalinga,
California. The solar facility demonstrates solar thermal technology’s ability to cleanly
and cost-effectively support enhanced oil recovery efforts in California and around the
world. BrightSource’s LPT technology was selected through a competitive process and
the project began construction in 2009.
Extracting heavy-oil reserves, like the ones found at Coalinga, is a global challenge.
According to a recent report by SBI, conventional oil recovery methods are only able to
extract about 10% - 30% of the original oil from any given reservoir, leaving nearly 70% 90% of the reservoir’s oil untouched. The report estimates that an additional 241.7
billion barrels of oil could be added to worldwide proven reserves with the
implementation of enhanced oil recovery methods.

・SolarReserve (アメリカ)
SolarReserve was formed to solve two of the fundamental barriers of renewable energy:
scalability and storage. Unlike hydroelectric, geothermal, biomass, and other renewable
energy technologies that use limited renewable fuel sources, SolarReserve's power
plants draw their heat from the sun - earth's ultimate source of clean energy. And unlike
wind and photovoltaics, SolarReserve's power plants can deliver power whenever it is
needed, either 24 hours per day or only during "peak" demand. By overcoming these two
key barriers, SolarReserve enables utility-scale, clean, renewable electricity generation
Crescent Dunes Solar Energy Project プロジエクト(not yet approved)
SolarReserve is currently developing the Crescent Dunes Solar Energy Project near
Tonopah, Nevada. Once constructed, it will power up to 75,000 homes during peak

・Solar Millennium(ドイツ)
As Europe's first ever parabolic trough power plants, Andasol 1 and 2 are in operation
since 2008 and 2009 on the Guadix plateau in the province of Granada. Flagsol GmbH,
Solar Millennium AG's technology subsidiary, supplied engineering services for the
solar field, i.e. planning, design and construction supervision as well as the control.
Upon completion of the power plants, all the stakes in the power plant companies were
sold (to ACS/Cobra) in accordance with the business model. According to ACS Andasol 1
provides 175 gigawatt hours per year, exceeding the expectations.
In the immediate vicinity Andasol 3 was built, which is essentially identical to Andasol
1 and 2. The plant, which was realized by Solar Millennium and its partners, is owned
by Solar Millennium, Ferrostaal, RWE Innogy, RheinEnergie and Stadtwerke München
(50%). The plant was inaugurated officially in september 2011.
Andasol Power Plants プロジエクト(稼働中)
Solar Millennium developed with Andasol 1 - 3 the first parabolic trough power plants
in Europe. With a collector surface area of over 1.5 million square meters - equal to 210
soccer pitches - they are the largest solar power plants in the world.
The three Andasol-plants together provide approximately half a million people in
southern Spain with environmentally friendly solar electricity. They will also contribute
to Spain's supply reliability and, in particular, cover the demand peaks in the Spanish
electricity grid during the summer months. The increased electricity demand is
primarily caused by the high energy consumption of air-conditioning units. Each power
plant has an electricity output of 50 megawatts and operates with thermal storage. A
full thermal reservoir can continue to run the turbines for about 7.5 hours at full-load,
even if it rains or long after the sun has set. The heat reservoirs each comprise of two
tanks measuring 14 m in height and 36 m in diameter and contain liquid salt. Each
provides 28,500 tons of storage medium.
As Europe's first ever parabolic trough power plants, Andasol 1 and 2 are in operation
since 2008 and 2009 on the Guadix plateau in the province of Granada. Flagsol GmbH,

time during a test phase.
RWE states that this test is a step on
the
way
to
completing
and
commissioning the 50MW plant, which
is scheduled to being commercial
operation in October 2011.
The Andasol 3 plant uses a parabolic
trough design, comprised of more than
200,000 parabolic mirrors. The plant
includes a molten salt thermal storage
system which developers say will
enable the plant to generate electricity
for up to eight hours after the sun has
gone down.
The Andasol 3 CSP plant
The Andasol 3 is the third in the
Andasol series of plants in Southern
Spain. The 10MW Andasol 1 was
Europe's first commercial parabolic
