Solar Cheap Enough to Compete Without Subsidies in Some States

YANKTON, S.D. - Solar power has become cheap enough to be competetive with other forms of commercial energy in some parts of the United States. A sharp, long-term fall in the price of solar cells has led The Economist magazine and others to declare that in sunny areas with high electricity prices, solar power is now cheap enough to compete without government subsidies.

Rory McIlmoil, program manager for the energy program at environmental consulting firm Downstream Strategies, says that applies to places like South Dakota and the northern plains.

"In those areas, solar is competing with other sources of energy that have higher electricity prices, which makes it a lot more likely that solar can compete."

One central criticism of renewable energy sources such as solar power is that they are too expensive. McIlmoil says that's rapidly changing, as solar's explosive growth shows.

He says the price of building a solar power plant is nearing where it would be competitive with a new coal plant of a similar capacity. He says both cost more than a natural gas plant, but he says solar has the advantage of free fuel.

"Natural gas peaker plants have other costs associated with their operation that solar power does not. High fuel and, depending on the size, high maintenance costs for your traditional power plants verses solar power plants."

Peaker plants are designed to kick in at times of peak power demand, to supplement regular power sources.

The solar industry still depends on significant federal subsidies, although McIlmoil points out that overall, the much larger fossil fuels industries actually receives more in tax breaks. Solar is also limited by the inconsistent nature of the sunshine, although he says power storage and flexible use of the grid are easing some of those issues.

He says that thanks to cheap solar cells, 2010 saw what was then a record level of solar power installed.

"And just one year later, twice that much was installed. Roughly 80 percent of the solar power that currently exists in the United States was installed just over the last three years."

South Dakota ranks 14th in the country for solar power potential, according to a survey by the National Renewable Energy Lab.

The Economist magazine also says that at current growth rates wind power will surpass nuclear in ten years.
