Levelized Cost Comparisons Help Explain Value of Various Electric Generation Technologies (EIA)
When power plants are built, several factors influence the choice of fuels and technologies that will ultimately generate electricity. Cost is one of the most difficult factors to compare, as technologies can have vastly different capital, fuel, maintenance, and financing costs, as well as different utilization rates and access to fuel resources. Two measures, the levelized cost of electricity (LCOE) and the levelized avoided cost of electricity (LACE), are widely used to make cost comparisons across technologies.
