A recent NREL report finds that concentrating solar power systems (CSP) with thermal energy storage (TES) provide value to the grid that is $30/MWh to $51/MWh higher than conventional base load generation. The analysis focused on grid performance in California under a 33% renewable scenario.

Today, from security and battlefield readiness to cost savings and efficiency, America’s military is making an unprecedented commitment to renewable energy sources, and solar is “walking point” on many of these new, innovative efforts.
Through the third quarter of 2011, the U.S. solar market installed more than 1 gigawatt (GW) of grid-connected photovoltaics (PV) on the year, far surpassing the 2010 annual total of 887 megawatts (MW). The third quarter of 2011 was also the largest quarter for installations ever seen in the U.S., supported by utility-scale project completions and rapidly declining prices for PV modules.
In 2010, the U.S. installed 887 megawatts (MW) of grid-connected PV, 104% growth over the 435 MW installed in 2009. Despite this, U.S. market share of global installations fell to 5.1%, down from 6.0% in 2009. Over the past six years, the U.S. has been growing at a relatively even pace with the global market; as a result, U.S. market share of global installations has consistently hovered between 5% and 7% since 2005. In 2011, however, this pattern is likely to end. A first-half slowdown in major European markets (most notably Italy and Germany) combined with continued strength in the U.S. has already led most PV manufacturers and developers to seek opportunities in the U.S. market with many in the industry expecting the it to be the largest market in the world within a few years.
In 2011, however, this pattern is likely to end. A slowdown in major European markets (most notably Italy and Germany)2, combined with the continued strength of the U.S. market, has already led most PV manufacturers and developers to seek opportunities in the U.S. We anticipate an exciting, if volatile, year in the U.S. PV market. This report catalogues the beginning of this period.
The U.S. solar energy industry grew to new heights in 2008 and many industry observers expect thatgrowth to continue in 2009. Total capacity grew by 1,265 megawatts (MW)1 in 2008, up from 1,159 MW installed in 2007.2 This brings the total installed capacity up by 16 percent to 9,183 MW. Capacity in both photovoltaic (PV) and solar water heating systems grew at record levels. And while no new concentrating solar power (CSP) plants were completed in 2008, projects totaling more than 6,000 MW are in the pipeline most with signed purchase power agreements. Solar pool heating capacity grew at a slower rate than in 2007, reflecting conditions in the residential real estate market.
At high penetration of solar generation there are a number of challenges to economically integrating this variable and uncertain resource.
Concentrating solar power (CSP) deployed with thermal energy storage (TES) provides a dispatchable source of renewable energy.
Establishing interconnection to the grid is a recognized barrier to the deployment of distributed energy generation. This report compares interconnection processes for photovoltaic projects in California and Germany.
More than half of the electricity produced in the southeastern states is fuelled by coal. Although the region produces some coal, most of the states depend heavily on coal imports.
