How much tax equity has been raised for solar and wind projects?

Norton Rose Fulbright (2020a) reported that approximately $12 billion in tax equity was raised in both 2018 and 2019 for solar and wind projects, representing approximately 40% and 55% of total project costs, respectively.

What are the advantages of solar and wind power?

Having no marginal costs (fuel and variable O&M costs), solar and wind power are typically utilized whenever they generate, thereby displacing generators with higher marginal costs and lowering wholesale electricity prices at the time.

How will wind and solar generation costs change over time?

Whereas wind and solar generation costs are projected to decrease modestly over time—a 26 percent decline in wind and 32 percent decline in solar LCOE over the next 22 years—generation value and integration costs can change more rapidly.

What are the integration costs of a wind or solar plant?

Integration costs may be incurred by the wind or solar plant, but are often borne by existing generators or elsewhere in the system. While dispatchable plants also impose integration costs, the integration costs of intermittent plants become significantly larger with increasing intermittent generation on the grid.

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.

How does storage energy capacity affect solar power?

As storage energy capacity costs increase, the solar power plant size increases (B), optimal storage duration decreases (C), and storage power capacity relative to output power increases (D). Solar cost of ownership is estimated as $1,000/kW for all three cases, and the EAF is 100%.
