Troughs Tower Comparison

NREL: Troughs and Towers Deliver Similar Value

A new National Renewable Energy Laboratory (NREL) report finds that parabolic troughs and receiver towers deliver similar value for CSP plants.

The report, “Estimating the Performance and Economic Value of Multiple CSP Technologies in a Production Cost Model,” compares dry-cooled towers with dry-cooled troughs at the same annual capacity (1.2 terawatt-hours), and with comparable levels of thermal storage.

It finds that the two technologies produce different production patterns when measured over daily and seasonal time scales, but both operate at 70 percent capacity factor and the total value to the grid is similar. Annual operational savings, relative to fossil fuel plants, run 3.6 percent for towers and 3.7 percent for troughs, at today’s prices for coal and natural gas.



GE Reaffirms Commitment to Large-Scale Solar

In a blog post, General Electric’s chief engineering officer writes: “Solar power generation is a hot commodity in the renewables energy market – last year, it topped the charts for renewable energy production growth, passing the 100 terawatt hour mark with 65% year on year growth in 2013. This is a marked shift from decades of slow growth, and a global challenge to deliver a significant proportion of energy demands from renewable sources.” And so, GE is developing products to support very large solar projects, including a 4MW, 1500-volt inverter. More
