Average solar LCOE increases for first time this year

Published:

A brand new report by Lazard compares the levelized price of power (LCOE) for various technology applied sciences on a $/MWh foundation. It reveals that utility-scale photo voltaic and onshore wind LCOE will increase for the primary time in 2023, by $24/MWh to $96/MWh for photo voltaic and $24/MWh to $75 MWh for wind. Nonetheless, each renewable sources are nonetheless the financial leaders in comparison with nuclear, gasoline, and coal.

Photo voltaic and wind are nonetheless the most affordable sources of electrical energy, however their LCOE will enhance for the primary time in 2023, in accordance with a brand new report by US-based monetary agency Lazard.

The report gives a comparative LCOE evaluation for varied technology applied sciences on a $/MWh foundation, with exceptions for US federal tax subsidies, gas costs, carbon pricing, and the price of capital. The report additionally features a cost-of-firming-intermittency evaluation for the primary time. Not like earlier years, the LCOE for utility-scale photo voltaic ditches thin-film expertise and focuses solely on crystalline silicon.

Within the base comparability, with out contemplating subsidies, gas costs, or carbon pricing, utility-scale photo voltaic and wind have the bottom LCOE of all sources. Utility-scale photo voltaic PV is available in wherever from $24/MWh to $96/MWh, whereas onshore wind registers the bottom doable LCOE within the shortest vary, from $24/MWh to $75/MWh. Offshore wind’s LCOE ranges between $72/MWh and $140/MWh.

For comparability, below the identical standards, gasoline peaking reaches $115/MWh to $221/MWh, nuclear is $141/MWh to $221/MWh, coal is $68/MWh to $166/MWh, and gasoline mixed cycle is $39/MWh to $101/MWh, in accordance with Lazard.

Unsubsidized residential rooftop PV has an LCOE between $117/MWh and $282/MWh, whereas the LCOE of group and industrial and industrial (C&I) photo voltaic ranges between $49/MWh and $185/MWh. When factoring within the federal tax subsidy below the US Inflation Discount Act, together with the home contest provisions, rooftop PV goes from $74/MWh to $229/MWh, and group/C&I rooftop PV to $32/MWh to $155/MWh.

For the primary time in Lazard’s evaluation historical past, the typical LCOE for utility-scale PV and onshore wind elevated. Inflation, provide chain challenges, and the worldwide power disaster have all performed a job in halting photo voltaic’s “race to the underside.” Nonetheless, Lazard says that “the LCOE of the best-in-class onshore wind and utility-scale photo voltaic has fallen beneath our price, causes that will encourage ongoing consolidation throughout the sector.”

For utility-scale PV, the LCOE vary in 2021 could be very small, at $30/MWh to $41/MWh. In 2023, it’s going to go from $24/MWh to $96/MWh, thus rising the typical LCOE.

Lazard estimates that between 2016 and 2023, utility-scale PV’s LCOE will enhance by 3%, calculated as the typical proportion enhance on the high-end and low-end of the LCOE vary. Between 2009 and 2023, nevertheless, the LCOE of photo voltaic will lower by 84% in accordance with the identical metric.

The brand new report additionally contains an evaluation of the extent price of hydrogen storage, which pv journal might be coated in separate articles.
