Breaking Ground: Work Starts on World's Biggest Solar Plant

1,000 megawatts of solar thermal on its way to Southern California

Breaking Ground: Work Starts on World's Biggest Solar Plant

California governor Jerry Brown and U.S. Secretary of the Interior Ken Salazar were both on hand on Friday for the ground-breaking ceremony of what will be the largest solar power plant in the world. The Blythe Solar Power Project, in Riverside County, Calif., will be home to 1,000 megawatts of solar thermal power.

The Blythe project, along with others like the much discussed Ivanpah project, represents a trend toward truly utility-scale solar power. Moving these projects forward to the point of actually beginning construction has been a challenge, with wildlife and other concerns standing in the way. In the case of Blythe, developer Solar Millennium was required by the Bureau of Land Management to fund 8,000 acres of protected land for desert tortoises and other threatened species. This is intended to roughly offset the 7,030 acres that will be disturbed by construction and by the resulting solar thermal plant. There have also been water-related issues to overcome, which changed the initial design.

Blythe will be built in phases, with the first electricity flowing toward homes—about 300,000 of them—by 2013. And though no large solar plants like this yet exist, Blythe will soon be followed by others: In 2010 alone, the BLM approved solar projects on public lands that total more than 3,500 megawatts of capacity. To put that in context, the Solar Energy Industries Association put the total installed solar capacity in the United States at the end of 2010 at only 2,593 megawatts.

This photograph shows a car with the words “We Drive Solar” on the door, connected to a charging station. A windmill can be seen in the background.

The Dutch city of Utrecht is embracing vehicle-to-grid technology, an example of which is shown here—an EV connected to a bidirectional charger. The historic Rijn en Zon windmill provides a fitting background for this scene.

We Drive Solar

Hundreds of charging stations for electric vehicles dot Utrecht’s urban landscape in the Netherlands like little electric mushrooms. Unlike those you may have grown accustomed to seeing, many of these stations don’t just charge electric cars—they can also send power from vehicle batteries to the local utility grid for use by homes and businesses.

Debates over the feasibility and value of such vehicle-to-grid technology go back decades. Those arguments are not yet settled. But big automakers like Volkswagen, Nissan, and Hyundai have moved to produce the kinds of cars that can use such bidirectional chargers—alongside similar vehicle-to-home technology, whereby your car can power your house, say, during a blackout, as promoted by Ford with its new F-150 Lightning. Given the rapid uptake of electric vehicles, many people are thinking hard about how to make the best use of all that rolling battery power.
