Across markets worldwide, average curtailment rates for wind and solar are generally quite low, often around 3%. However, these low average curtailment rates may overstate how much renewable supply increases as a result of further increases in renewable capacity.
Fitch Ratings-Hong Kong-10 May 2024: China's solar and wind power curtailment rates may continue to rise in the near term, as the improvement in the power system's ability to consume renewables may lag the pace of aggressive capacity additions, says Fitch Ratings.
While just 0.4% of the potential wind generation is curtailed during our sample period, we again find that only 90% of the midday output from new wind capacity goes towards increasing the state's renewable supply. The remaining 10% goes towards increasing solar curtailments.
Curtailment is when electricity generation is deliberately reduced below its maximum generation potential. Wind generation increased by 42% between 2019 and 2023 and makes up a substantial proportion of the energy mix in the Midwest.
Solar and wind power curtailment rates rose to 4% and 3.9% in 1Q24, 2pp and 0.7pp up yoy, respectively, as capacity additions continued to break records. China added 45.8GW of solar
The latest information and the future estimations of curtailment in several countries/areas are summarised, including Ireland, California and Texas in U.S., and Japan.
Across markets worldwide, average curtailment rates for wind and solar are generally quite low, often around 3%. However, these low average curtailment rates may overstate how much
The monthly curtailment rates are equal to the total monthly curtailment in the CAISO market of utility-scale solar (wind) divided by the monthly potential utility-scale solar (wind)
Figures 3 and 4 illustrate wind and solar curtailment, respectively, in selected countries or areas in the form of C-E maps (correlation maps between energy share of wind/solar/wind+solar and annual
Curtailment is when electricity generation is deliberately reduced below its maximum generation potential. Wind generation increased by 42% between 2019 and 2023 and makes up a
Curtailments occur when wind and solar are capable of generating electricity, but operators cannot dispatch that electricity into the grid. This data-file tabulates curtailment rates in
The following charts show the daily and 7-day wind and solar curtailment by category, if any. The following charts show hourly year to date wind and solar curtailment by category, if any. The
Although VRE curtailment is increasing overall, the share of curtailed wind and solar PV generation remains relatively low, ranging from 1.5% to 4% in most large renewable energy markets.
Wind curtailment is the intentional reduction of wind power output to maintain grid stability. Learn about its causes, impacts, and strategies to minimise curtailment.
