Solar Thermal Energy an Industry Report
Solar Thermal Energy an Industry Report . Solar Thermal Technology on an Industrial Scale The Sun is Our Source Our sun produces 400,000,000,000,000,000,000,000,000 watts of energy every second and the belief is that it will last for another 5 billion years. The United States An eSolar project in California. reached peak oil production in 1970, and there is no telling when global oil production will peak, but it is accepted that when it is gone the party is over. The sun, however, is the most reliable and abundant source of energy. This site will keep an updated log of new improvements to solar thermal and lists of projects currently planned or under construction. Please email us your comments at: [email protected] Abengoa’s PS10 project in Seville, Spain. Companies featured in this report: The Acciona Nevada Solar One plant. Solar Thermal Energy an Industry Report . Solar Thermal vs. Photovoltaic It is important to understand that solar thermal technology is not the same as solar panel, or photovoltaic, technology. Solar thermal electric energy generation concentrates the light from the sun to create heat, and that heat is used to run a heat engine, which turns a generator to make electricity. The working fluid that is heated by the concentrated sunlight can be a liquid or a gas. Different working fluids include water, oil, salts, air, nitrogen, helium, etc. Different engine types include steam engines, gas turbines, Stirling engines, etc. All of these engines can be quite efficient, often between 30% and 40%, and are capable of producing 10’s to 100’s of megawatts of power. -

Some applicants have assumed aggressive project schedules. For example, both UCT and EWT assume that the leave to construct process – from application to decision – can be completed in less than one year. The generalized phase-by-phase project schedule of each applicant is shown in the table below. The questions below are intended to test the reasonableness of the scheduling assumption and the sensitivity of development and construction cost estimates to changes in the project schedule that underpins each such estimate.

NV Energy North Bordertown to California Sub 120 kV Project This project is comprised of a new 345/120 kV 280 MVA transformer at NVE’s Bordertown Substation and a 120 kV, 11-mile line from Bordertown to California substation. This project is expected to be in service by end of 2025. Multiple studies on the project have been performed by NVE indicating that no significant regional impact from these internal transmission facilities can be expected. West Tracy 345/120 kV Transformer This project is driven by expected load growth in the Reno/Tracy area. The project includes the construction of a new 120 kV switchyard and a new 345/120 kV 280 MVA transformer at the existing West Tracy substation. This project is planned to be in service in 2022. Multiple studies on the project have been performed by NVE indicating that no significant regional impact from this internal transmission facility can be expected.

Concentrated Solar Power Focusing the Sun’S Energy for Large‐Scale Power Generation
Concentrated Solar Power Focusing the sun’s energy for large‐scale power generation August 2009 Concentrated solar power (CSP) is a method of electric generation fueled by the heat of the sun, an endless source of clean, free energy. Commercially viable and quickly expanding, this type of solar technology requires strong, direct solar radiation and is primarily used as a large, centralized source of power for utilities. In contrast, photovoltaic cells are effective in a wider range of regions and applications. CSP plants generate power best during the late afternoon – during peak demand – and can displace the use of fossil fuel plants that emit the greenhouse gases that cause climate change. As energy storage technology continues to advance, more CSP plants will be able to provide baseload power throughout the night. TECHNOLOGY CSP, also called solar thermal power, uses mirrors to focus sunlight onto a heat‐transfer medium. The steam produced from the heat‐transfer medium powers a turbine or engine that generates electricity. Depending on the type, CSP plants can supply up to 100 megawatts (MW) with a potential to produce up to 300 MW, on par with other utility‐scale power plants. Effective CSP requires solar radiation of at least 5.5 kWh/m2/day – California averages 6.75‐8.25 kWh/m2/day1 – and functions best in arid, flat locations. The U.S. Southwest, Sahara Desert, and Australia have the highest potential capacity for CSP in the world.2 TYPES OF CSP SYSTEMS Parabolic Trough: Long, curved mirrors pivot to concentrate sunlight onto tubes filled with a heat transfer fluid, generally oil or water, whose steam California Parabolic Trough moves a power‐generating turbine.
