The length of term allowed for power sales contracts is a critical determinant of the ability of states to meet their increasingly ambitious renewable power targets. Many utilities advocate limiting terms to 10 or perhaps 15 years for renewable energy contracts, emphasizing the "flexibility" that shorter terms offer. In contrast, contract terms of 20 or […]

The world’s largest solar electric system was dedicated in June 2005 in Mühlhausen, Germany. The 10-MW system comprises three separate but interconnected photovoltaic parks in different cities that use an innovative sun-tracking system to maximize their outputs. After one year of operation, all three parks are still going strong—as you’d expect, due to their dearth of moving parts.

We tend to forget that today’s super-sized power plant designs began life as small prototypes that grew in size only as fast as technology and economics allowed. Arizona Public Service, a long-time leader in solar energy development, has invested in the development of one such technology that is compatible with the sunny Southwest and certain to become more cost-competitive in the near future. This successful demonstration of a 1-MW concentrated solar power, trough-style energy system is the first to have put power on the grid since 1988. But it certainly won’t be the last.

In an effort to tap the significant solar energy resources of New Mexico, Arizona, Nevada, California, Utah, Texas, and Colorado, the U.S. DOE will support efforts to install a total of 1,000 MW of concentrating solar power (CSP) systems over the next five years. "This initiative will provide a substantial engine for economic development, job […]
