This is reflected in the Lazard report. The report shows a steep decrease in the LCOE for PV solar, with a drop of 88 percent in the last 9 years and a compound annual growth rate (CAGR) of 21 percent. The LCOE for wind energy has a similar trend with a decrease of 69 percent in the last 9 years and a CAGR of 12 percent.
While incentives are still a large component of the renewable energy market, the Lazard report shows that its influence, especially with utility-scale PV solar, is waning. Incentives have much more of an effect on residential PV and wind energy.
When compared to conventional generation such as nuclear and coal, the Lazard report shows that utility-scale PV and wind have a much lower LCOE. Much of this is due to increased competition in the market as well as capital cost factors, such the supply chain and improved technology. While wind has been competitive since 2011, according to Lazard, utility-scale PV solar has only been competitive in the last couple of years.
We expect the trends shown in the Lazard report, especially with utility-scale PV and wind, to continue in the next 10 years. The Department of Energy’s SunShot 2030 goal is to cut the LCOE of utility-scale PV by an additional 50% by the year 2030. Following the current trend, we expect the LCOE for PV solar will reach the goal in 2028. The SunShot program, which began in 2011, has been instrumental in reducing the cost of LCOE for PV solar without subsidies. The solar industry achieved the initial SunShot 2020 goal of $0.06 per kilowatt-hour for utility-scale PV 3 years ahead of schedule.
Our analysis is based on several factors. Capital costs will continue to reduce, while technology will continue to improve. Also, the implementation and advances in energy storage will be crucial to wind and solar. The wind doesn’t always blow and the sun doesn’t always shine during peak demand, resulting in curtailed wind energy production and clipped solar production. The SunShot 2030 goal includes integration of PV solar with storage as an integral part of reducing the LCOE by half. The Lazard analysis cites the ability for energy storage to not only capture otherwise lost energy, but also share interconnection and inverter costs, as reasons why the LCOE of utility-scale PV solar and wind may decrease in the future. In addition, the trend of mothballing and not replacing older conventional generation facilities will only increase demand and market penetration for renewables.
