Solar Shines As Regulatory Battles Abound

A tough legal and financial terrain is confronting producers, utilities and regulators.

State commissions are challenged to find the sweet spot whereby utilities can afford to maintain their systems and homeowners are motivated to go green.

Solana, the First Large-Scale Solar Plant with Thermal Energy Storage in the U.S., Passes Commerical Operation Tests

Abengoa announced that Solana, the world´s largest parabolic trough plant and also the first solar plant in the United States with thermal energy storage, has successfully passed commercial operation tests. A thermal energy storage system allows Solana to generate electricity for six hours without the concurrent use of the solar field. This technology consists of parabolic shaped mirrors mounted on structures that track the sun and concentrate the sun's heat, later transforming water into steam and powering a conventional steam turbine.

Solar Hype and Hope

Utility-scale projects suffer growing pains.

Anyone who’s been watching the solar power industry for more than a few years can’t help but be impressed by the recent explosion of large-scale projects. It seems akin to the rapid scale-up of wind in the late 1990s and early 2000s—when megawatt-scale turbines became standard-issue, and the definition of a “large” wind farm changed from a capacity of 20 MW to something more like 200 MW.

Solar Expansion

Technologies are scaling up quickly to meet industry needs.

Like other California electric utilities, San Francisco-based Pacific Gas & Electric (PG&E) has been scrambling to meet the state’s renewable portfolio standard (RPS), which requires suppliers to obtain at least 20 percent of their power from renewable energy sources by 2010. Though the RPS includes a variety of technologies, renewables developers are choosing utility-scale solar power more than any other resource, says Hal La Flash, PG&E’s director of emerging clean technologies.
