WASHINGTON – A new study from the Institute for Energy Research finds that electricity from new wind and solar power is 2.5 to 5 times more expensive than electricity from existing coal and nuclear power.

This innovative study relies on data from the Energy Information Administration and the Federal Energy Regulatory Commission to find the levelized cost of electricity from existing plants, not just the cost of electricity from new power plants as is typical with many studies.

In addition, IER’s study estimates the costs imposed on the grid by the intermittent nature of wind and solar power. Factoring in these “imposed costs” provides a more realistic estimate of what electricity from new wind and solar power costs. In fact, solar power’s imposed costs actually increase as more capacity is added to the system.

The following chart shows the stark contrast between the cost of electricity from existing and new sources:

As the chart indicates: Electricity from new solar is nearly 5 times more expensive than from existing nuclear and over 3.5 times more expensive than from existing coal.

than from existing nuclear and over than from existing coal. Electricity from new wind is over 3.5 times more expensive than from existing nuclear and over 2.5 times more expensive than from existing coal. “Much of our existing coal and nuclear fleet could continue to provide affordable, reliable electricity for decades to come if not for policies like the Obama administration’s carbon regulations or the deal struck in California to shut down Diablo Canyon,” said IER President Thomas Pyle.

“Unnecessarily shutting down our existing generation in favor of expensive and intermittent wind and solar power means Americans will be left with higher electricity bills and less money in their pockets. This will have the harshest impact on poor and middle class families who spend more of their hard-earned money on energy costs. This study adds a much-needed reality check to the debate over our nation’s electricity policy.”

This study was conducted by Tom Stacy, a former member of the ASME Energy Policy Committee, and George Taylor, PhD, the director of Palmetto Energy Research. The source of the calculations used in this study is a compilation of data reported by the generators themselves to FERC and EIA.
