The input value used for onshore wind in AEO2022 was $1,411 per kilowatt (kW), and for solar PV with tracking, it was $1,323/kW, which represents the cost of building a plant excluding regional factors.
Capital costs tend to be low for gas and oil power stations; moderate for onshore wind turbines and solar PV (photovoltaics); higher for coal plants and higher still for waste-to-energy, wave and tidal, solar thermal,
Measured by any metric, the cost of wind and solar power has decreased sharply during the past decade. Figure 6 displays the generation costs of onshore wind energy and those of solar PV, as derived from
The levelized cost of electricity (LCOE) for technologies like solar and wind power represents the per-unit cost of electricity generation over the entire lifespan of a power plant, encompassing initial capital
This chart shows the levelized cost of energy generation by source (in U.S. dollar per MWh).
Solar photovoltaic systems ($800-$1,000/kW) and onshore wind projects ($1,200-$1,500/kW) are also among the lower-cost power generation options primarily due to the simpler technology, shorter
Renewables continue to prove themselves as the most cost-competitive source of new electricity generation. On an LCOE basis, 91% of newly commissioned utility-scale renewable capacity delivered power at a lower cost
Baseload Power Needs Will Require Diverse Generation Fleets Despite the sustained cost-competitiveness of renewable energy technologies, diverse generation fleets will be required to meet baseload power needs over
The average cost per unit of energy generated across the lifetime of a new power plant. This data is expressed in US dollars per kilowatt-hour. It is adjusted for inflation but does not account for differences in living costs
