The Institute for Energy Research and the American Coalition for Clean Coal Energy released a new study evaluating the levelized cost of electricity (LCOE) from new and existing generation resources.
This innovative study takes into account several important considerations that other reports do not when calculating LCOE. These include the imposed costs of wind and solar generation, as well as the costs of operating existing generation sources in addition to those of building and operating new plants. Including these considerations presents a fuller picture of the operating costs of wind, solar, coal, gas, nuclear, and hydroelectric sources.
The chart below shows that new wind and solar installations are two to three times more expensive than existing generation sources.
