The objective of this 18 month subcontract was the improvement of reflective optics CPV panels to enable the large-scale, reliable production of solar electricity to meet SAI-established LCOE targets, and ultimately provide a path to solar power at parity with or better than the cost of energy generated utilizing fossil fuels. To this end, SolFocus has completed this subcontract with great success as evidenced by the end results of a CPV panel with conversion efficiencies greater than the targeted 22% and manufacturing capabilities with a run rate capacity far exceeding the milestone benchmark >3MW.


Wind Energy And Power System Operations: A Review Of Wind Integration Studies To Date, Jennifer Decesaro, Kevin Porter Dec 2009

Wind Energy And Power System Operations: A Review Of Wind Integration Studies To Date, Jennifer Decesaro, Kevin Porter

Publications (E)

This paper provides an overview of the challenges associated with wind integration and summarizes the findings of the wind integration studies conducted over the course of the past five years. We begin with an overview of the approximate time frames used in grid operations. We then describe how wind integration studies are conducted, discuss the results on wind integration costs and grid impacts from these grid integration studies, and assess some of the grid planning and operation changes that may be necessary to incorporate higher levels of wind generation. We close with several conclusions.


Examination Of The Regional Supply And Demand Balance For Renewable Electricity In The United States Through 2015, Lori Bird, David Hurlbut, Pearl Donohoo, Karlynn Cory, Claire Kreycik Mar 2009

Examination Of The Regional Supply And Demand Balance For Renewable Electricity In The United States Through 2015, Lori Bird, David Hurlbut, Pearl Donohoo, Karlynn Cory, Claire Kreycik

Publications (E)

This report examines the balance between the demand and supply of new renewable electricity in the United States on a regional basis through 2015. It expands on a 2007 NREL study (Swezey et al. 2007) that assessed the supplynational basis. As with the earlier study, this analysis relies on estimates of renewable energy supplies compared to demand for renewable energy generation needed to meet existing state renewable portfolio standard (RPS) policies in 28 states, as well as demand by consumers who voluntarily purchase renewable energy. However, it does not address demand by utilities that may procure cost-effective renewables through an …
