Solar power generation development cost

In 2023, the global weighted average levelised cost of electricity (LCOE) from newly commissioned utility-scale solar photovoltaic (PV), onshore wind, offshore wind and hydropower fell.

In 2020, large utility-scale systems produced electricity at a levelized (life-cycle) cost below 5¢/kWh in locations with average sunlight, and as low as 3.5¢/kWh in the sunniest parts of the country, making it one of the least expensive forms of new electricity generation. 1. This reduction in cost in combination with solar policy incentives .

In 2022, the global weighted average levelised cost of electricity (LCOE) from newly commissioned utility-scale solar photovoltaics (PV), onshore wind, concentrating solar power (CSP), bioenergy and geothermal energy all fell, despite rising materials and equipment costs.

All technologies demonstrate some degree of variability in cost, based on project size, location, and access to key infrastructure (such as grid interconnections, fuel supply, and transportation). For wind and solar PV, in particular, the cost favorability of the lowest-cost regions compound the underlying variability in regional cost and .

For technologies with no fuel costs and relatively small variable costs, such as solar and wind electric-generating technologies, LCOE changes nearly in proportion to the estimated capital cost of the technology.

6 FAQs about [Solar power generation development cost]

Are solar PV projects reducing the cost of electricity in 2022?

Between 2022 and 2023, utility-scale solar PV projects showed the most significant decrease (by 12%). For newly commissioned onshore wind projects, the global weighted average LCOE fell by 3% year-on-year; whilst for offshore wind, the cost of electricity of new projects decreased by 7% compared to 2022.

Are 'projected costs of generating electricity' falling?

The key insight of the 2020 edition of Projected Costs of Generating Electricity is that the levelised costs of electricity generation of low-carbon generation technologies are falling and are increasingly below the costs of conventional fossil fuel generation.

What is projected costs of generating electricity – 2020 edition?

Projected Costs of Generating Electricity – 2020 Edition is the ninth report in the series on the levelised costs of generating electricity (LCOE) produced jointly every five years by the International Energy (IEA) and the OECD Nuclear Energy Agency (NEA) under the oversight of the Expert Group on Electricity Generating Costs (EGC Expert Group).

What happened to solar power in 2022?

Will solar power increase in 2020?

This reduction in cost in combination with solar policy incentives has led to rapid growth in solar photovoltaic (PV) generation capacity, from providing less than 0.1% of the U.S. electricity supply in 2011 to over 3% in 2020. This upward trajectory is expected to continue.

What is the least cost option for solar power?

Nevertheless, in terms of the LCOE of the median plant, onshore wind and utility scale solar PV are, assuming emission costs of USD 30/tCO 2, the least cost options. Natural gas CCGTs are followed by offshore wind, nuclear new build and, finally, coal.
