Company Overview of BrightSource Energy, Inc.

Company Overview

BrightSource Energy, Inc., a solar thermal technology company, designs, develops, and sells proprietary systems to produce energy in utility-scale electric power plants in United States and internationally. The company’s systems use fields of tracking mirrors, known as heliostats, controlled by its proprietary software to concentrate sunlight onto a solar receiver/boiler unit to produce high-temperature steam. The steam produced in the solar receiver/boiler unit is used in a conventional steam turbine to produce electricity or in industrial applications, such as thermal enhanced oil recovery. It also acts as the system architect for the layout and optimization of the solar field; and provide...

BrightSource Energy, Inc. Key Developments

BrightSource Launches Next Generation Solar Field Technologies

BrightSource Energy, Inc. announced advanced solar field technologies currently being deployed at the 121 megawatt (MW) Ashalim Solar Thermal Power Station located in Israel’s Negev Desert. The fourth generation of BrightSource’s solar field technologies features improvements to the heliostats, solar field communications network and solar field control system. These technologies are designed to further optimize power production, reduce construction time and lower project costs. The 392 MW Ivanpah Solar Electric Generating System, located in California’s Mojave Desert, is the large CSP tower project and is entering its third year of operation. The Ashalim project, which is now under construction, builds on the experience gained at Ivanpah. BrightSource’s technologies being deployed at Ashalim are designed to deliver performance improvements in all areas of solar field operations. New Heliostat Design Improves Performance and Lowers Cost: With fewer components and an easier assembly, new heliostats cost less and can be installed much faster. BrightSource’s latest design measures 4 x 5.2 meters, 25% larger compared to Ivanpah. Each heliostat consists of four flat, low-iron glass mirrors that provide maximum reflectivity for the life of the project. The new streamlined design maximizes the total reflective surface within the constraints of the mechanical drive systems and allowable wind load. Precision steel parts, including a torque tube, support arms and connectors, ensure rigidity and reliability in desert conditions for more than 25 years. Dual-Axis Trackers Now Powered by the Sun: Each heliostat is individually controlled and features an integrated, dual-axis tracking system capable of 360 degree positioning. Movement is powered by a small photovoltaic panel and rechargeable lithium-ion battery power supply unit. Other components include a control module, azimuth drive system, and elevation drive system. This system significantly reduces electrical wiring and cabling in the solar field. Long-term reliability is also improved. Industry First Wireless Solar Field Communications and Control: BrightSource’s solar field integrated control system (SFINCS) manages the distribution of energy across the solar receiver using real-time heliostat-aiming and closed-loop feedback. At Ashalim, each of the 50,600 heliostats positioned in the 3.15-square-kilometer solar field will communicate wirelessly with the SFINCS. The wireless system reduces cabling by as much as 85% in the solar field, further reducing costs and accelerating the construction schedule. Ashalim represents the first deployment of the wireless SFINCS solution that was tested and independently validated at the company’s Solar Energy Development Center (SEDC), a fully operational “sun-to-steam” solar demonstration facility used to test equipment, materials and procedures as well as construction and operating methods. The latest version of SFINCS – BrightSource’s proprietary optimization and control software – maximizes project performance and power production efficiencies. These new algorithms enable increased heliostat density that yields higher energy output per square meter of the solar field.
