How has the cost of generating electricity changed over time?

Evidence(7)

  1. Empirically grounded technology forecasts and the energy transition: Joule

    [1]

    The frozen article snapshot contains only a short page shell with navigation and advertising elements. It provides no abstract, article text, methods, figures, tables, empirical observations, forecast results, or cost estimates. The title identifies a study about empirical technology forecasts and energy transition, but this snapshot cannot substantiate its conclusions.

    1

    Because the snapshot lacks substantive content, this source contributes no defensible evidence about how electricity-generation costs changed. It should not support a claim about learning rates, forecast accuracy, technology rankings, or future prices. The limitation is evidentiary, not a finding that costs remained stable or changed in a particular direction.

  2. Index | Electricity | 2024 | ATB | NLR

    [2]

    The 2024 Electricity Annual Technology Baseline standardizes capital expenditures, operating costs, capacity factors, and LCOE across electricity technologies. It provides base-year estimates and projections through 2050, under Conservative, Moderate, and Advanced advancement scenarios. Monetary values use 2022 dollars, and financial cases distinguish R&D-only assumptions from Market-plus-Policies assumptions for project comparisons.

  3. Levelized Costs of New Generation Resources in the Annual Energy Outlook 2026

    [3]

    EIA estimates 2031 U.S. new-build LCOEs using a 30-year recovery period and 7.27% after-tax WACC. Onshore wind costs $56.75/MWh and solar PV costs $58.33/MWh, while combined-cycle costs $77.46/MWh. Offshore wind costs $118.79/MWh, and advanced nuclear costs $87.81/MWh. It warns LCOE alone misses grid value and regional reliability when choosing investments.

  4. Projected Costs of Generating Electricity 2020 – Analysis - IEA

    [4]

    The IEA–NEA report compares 243 plants across 24 countries using a common plant-level LCOE method. It projects 2025 costs, finding onshore wind lowest on average in 10 of 14 countries. Offshore wind’s median fell below $100/MWh from above $150/MWh five years earlier. Renewables compete with fossil generation in many regions.

  5. Utility-Scale Solar

    [5]

    Berkeley Lab finds utility-scale PV installed cost fell 73% in real terms from 2010 to 2022, while average LCOE fell 82% to $48/MWh. Higher financing costs, capacity-factor changes, and rising CapEx then lifted LCOE 25% to $60/MWh in 2024. O&M declined from roughly $22 to $5/MWh between 2012 and 2024.

    [6]

    IPCC reports sustained 2010–2019 unit-cost declines of 85% for solar energy, 55% for wind energy, and 85% for lithium-ion batteries. Deployment expanded simultaneously, exceeding tenfold for solar and one-hundredfold for electric vehicles. By 2020, four renewable technologies had LCOEs already capable of competing with fossil fuels in many places globally.

  7. www.lazard.com

    [7]

    Lazard’s historical series reports 2009–2026 LCOE-range reductions of 52% for onshore wind and 81% for utility solar. From 2021 to 2026, those ranges rose 70% and 85%. The analysis attributes recent increases to capital costs, interest rates, tariffs, and supply-chain repricing, while renewables undercut fossil alternatives on an LCOE basis.
